SUMMARY Background Cinematic Rendering (CR) is a recently introduced post-processing 3D-visualization imaging tool. The aim of this study was to assess its clinical value in the preoperative planning of deep inferior epigastric artery perforator (DIEP) or muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps, and to compare it to maximum intensity projection (MIP) images. The study presents the first application of CR for perforator mapping prior to autologous breast reconstruction. Methods Two senior surgeons independently analyzed CR and MIP images based on computed tomography angiography (CTA) datasets of 20 patients in terms of vascular pedicle characteristics, the possibility to harvest a DIEP or MS-TRAM flap, and the side of the flap harvest. We calculated inter- and intra-observer agreement in order to examine the accordance of both image techniques. Results We observed a good inter- and intra-observer agreement concerning the type of flap and the side of the flap harvest. However, the agreement on the pedicle characteristics varies depending on the considered variable. Both investigators identified a significantly higher number of perforators with MIP compared to CR (observer one p Conclusion The current study serves as an explorative study, showing first experiences with CR in abdominal-based autologous breast reconstruction. In addition to MIP images, CR might improve the surgeon's understanding of the individual's anatomy. Future studies are required to compare CR with other 3D visualization tools and its possible effects on operative parameters.

Chronic hand ischemia causes cold intolerance, intractable pain, and digital ulceration. If ischemic symptoms persist despite pharmacologic treatments, surgical interventions should be considered. This retrospective study evaluated the long-term results after ulnar and radial reconstruction using an interpositional deep inferior epigastric artery (DIEA) graft combined with periarterial sympathectomy. Patients who underwent this surgery from March 2003 to February 2019 were included. To evaluate variables influencing recurrence after the procedure, patients were divided into the recurred and non-recurred groups and their data were compared. Overall, 62 cases involving 47 patients were analyzed (16 and 46 cases in the recurred and non-recurred groups, respectively). The median DIEA graft length was 8.5 cm. The rates of rheumatic disease and female patients were significantly higher in the recurred than in the non-recurred group, without significant between-group differences in postoperative complication rates. In the multivariate analysis, underlying rheumatic disease and graft length had significant effects on recurrence. In Kaplan–Meier analysis, the 5- and 10-year symptom-free rates were 81.3% and 68.0%, respectively, with lower rates for cases with rheumatic disease. Thus, arterial reconstruction using an interpositional DIEA graft provides long-term sustainable vascular supply in patients with chronic hand ischemia, especially in those without rheumatic disease.

Partial maxillectomy for maxillary sinus cancer treatment requires soft tissue reconstruction with enough bulk to occupy the large-volume defect. Deep inferior epigastric artery-based flaps and subscapular artery-based flaps are commonly used, but necessitate invasive muscle dissection or position change and a large recipient vessel. The aim of this report was to present a case of partial maxillectomy defect successfully reconstructed with a superficial circumflex iliac artery (SCIA) perforator (SCIP) flap, to address these drawbacks. A 67-year-old female underwent partial maxillectomy for maxillary sinus cancer. The defects included the medial and the caudal aspects of the maxillary sinus with unilateral palate loss. A double-paddle SCIP flap (19 × 9 cm and 10 × 6 cm) was elevated in a free-style manner based on the superficial branches of the SICA. The SCIP and its concomitant vein were anastomosed to a facial artery perforator and the angular vein with supermicrosurgical perforator-to-perforator anastomosis. Two skin paddles were utilized to reconstruct the defects of the nasal wall and the oral aspects of the palate. Postoperative course was uneventful, and the patient could resume normal oral diet 5 days after surgery. Three years after surgery, there was no cancer recurrence or any postoperative complication, and the patient was satisfied with normal speech and diet, and with concealable donor and recipient scars. Double-paddle SCIP flap transfer may be an option for reconstruction of a partial maxillectomy defect.

BACKGROUND: The length of the amputation stump is crucial for optimal prosthetic fitting and rehabilitation. Especially in traumatic amputation, direct closure of the stump may be challenging, and bone shortening is frequently needed. To avoid excessive bone shortening, coverage of exposed bone with free flaps is a versatile option. OBJECTIVE: Here we present our experience with the utilization of free flaps from the lower abdomen for the coverage of amputations stumps of the lower extremity. METHODS: Between March 2008 and October 2010, five patients (three female, two male) with complex wounds on amputation stumps of the lower extremity were treated with a mean age of 50 years (range: 15–72 years). Six abdominal free flaps were performed in five patients (one bilateral case), including four deep inferior epigastric artery (DIEP-) and two muscle-sparing transverse rectus abdominis muscle (ms-TRAM-) flaps. Patient’s and operative data were collected retrospectively. RESULTS: One complete flap failure occurred (overall success rate: 83.3%). Three of five patients gained full ambulatory status. CONCLUSIONS: Due to the low donor site morbidity a long vascular pedicle and the large amount of available tissue, abdominal based free flaps represent our first choice for microsurgical reconstruction of lower extremity stumps.

Background: There is an increasing evidence for the use of thin flaps based on vascular perforators for reconstructive surgeries. The medial sural and deep inferior epigastric artery flaps offer versatility for the reconstruction of major defects of the head and neck. Objectives: “Whether medial sural artery perforator (MSAP) flap or rectus abdominis perforator flap is better for the reconstruction of glossectomy defects in terms of functional outcome?” Data Sources: PubMed, Cochrane Library, clinicaltrials.gov and hand searches. Participants and Interventions: Patients who underwent tongue reconstruction with either MSAP flap or deep inferior epigastric artery perforator (DIEAP) flap. Study Appraisal and Synthesis Methods: Based on defined study criteria 6 studies were selected according to Prisma Guidelines. The overall estimated effect was categorized as significant where P < 0.05. Results: There was no significant difference between both flaps in terms of receptor site complications (P = 0.223). Overall odds ratio (OR) for complications was 1.35 (95% confidence interval [CI]: 0.412–0.736) and the test for overall effect t value was 2.836, P < 0.05. Overall OR was 6.01 (95% CI 0.5–7.45) and the test for overall effect t value was 1.41, P < 0.05 indicating there was a statistical difference in the intelligibility of speech. Limitations: Anatomical variations, under-reporting of studies and lack of universal tool for speech intelligibility. Conclusions and Implications of Key Findings: Both the flaps are comparable in terms of functional outcome. Medium-sized defects can be reconstructed with MSAP and composite larger defects would benefit from DIEAP. In females, anterolateral thigh flap still remains the choice for composite reconstructions.

Mobile smartphone thermal imaging (MTI) devices correlate with blood flow, which makes them appealing adjuncts during reconstructive surgery. MTI was assessed in the setting of deep inferior epigastric artery perforator (DIEAP) free flaps. We hypothesized that MTI can be a surrogate for blood flow to identify microvascular flow insufficiencies.Nineteen patients underwent 30 DIEAP flaps for breast reconstruction. Images were obtained preoperatively, intraoperatively, and at instances of concern for flap viability. Three groups were evaluated: normal DIEAP flaps (NDFs), flaps with arterial insufficiency (AI), and flaps with venous congestion (VC).All flaps were successful. There were significant temperature increases from max ischemia (24.5 ± 2.1°C) to 1 min after anastomosis (27.2 ± 1.6°C, P 0.001). NDFs continued to warm until the final MTI was taken when leaving the operating room. There were no differences between MTI flap temperatures before transfer to the chest and after completion of microanastomosis. With questionable flap viability, VC and AI temperatures were found to be significantly colder than the NDF group (28.3 ± 1.9°C versus 32.2 ± 1.8°C, P = 0.003) in the VC group and (27.2 ± 0.7°C versus 32.2 ± 1.8°C, P = 0.001) in the AI group. After correction of the identified flow insufficiency, VC and AI rewarmed and temperatures were no different compared with NDF.MTI recognizes microanastomotic failure and is a practical adjunct in the evaluation of free flap perfusion.

Summary: Gestational gigantomastia (GGM) is a rare condition characterized by a massive overgrowth of breast tissue during pregnancy. Surgical sanction may be required when conservative measures fail. In this study, we report the case of a 29-year-old woman who presented with an evolutive GGM responsible for physical and emotional distress, despite medical treatment. A multidisciplinary decision was made to induce delivery at 32 weeks. In the postdelivery period, the patient developed breast wounds, complicated with septic cardiomyopathy. An emergency bilateral mastectomy was then carried out, together with banking of both nipple-areola complexes. Thereafter, delayed bilateral 2-stage breast reconstruction was started at 12 months with subcutaneous tissue expanders, later on followed by implants removal and autologous reconstruction with bilateral deep inferior epigastric artery perforator flaps and bilateral nipple replantation.

Summary Background Perforator flaps yield the best results for the patient with the least morbidity, and they should be considered the gold standard in head and neck reconstruction. Although deep inferior epigastric perforator (DIEP) flap is considered as the gold standard in breast reconstruction, its use in head and neck reconstructive surgery does not seem so widespread. The objective of this study is to conduct a systematic review of the use, applications and results of the DIEP flap in the head and neck area. Methods Search was conducted in different indexed databases (PubMed/MEDLINE, the Cochrane Library, Scielo and Web of Science) and through meta-searcher Trip Database with deep inferior epigastric perforator flap AND head neck keywords. Studies on animal and human experiments published in peer-reviewed journals, where investigators assessed the use of DIEP flap, according to the Koshima criteria, in the head and neck area were considered. Results A total of 31 articles and 185 flaps with 95% of survival were found. Thrombosis or venous stasis is the most frequent cause of flap loss and 16.1% presented some type of complication, the most frequent being the dehiscence. The most use was in the reconstruction of glossectomy defect secondary to squamous cell carcinoma (30.51%), being able potentially to re-establish sensory innervation in oral cavity. The assessment of risk bias (National Institutes of Health) highlights the lack of uniformity, with no standardisation of the outcome variable collection and monitoring. Discussion By virtue of its versatility, reliable vascular supply and high flap survival rate, the DIEP flap reconstruction could be an option in complicated 3-dimensional head and neck defects while maintaining the standard of low donor site morbidity.

Background Seroma is one of the most common complications following body contouring. Progressive tension sutures (PTSs) have been shown to decrease the seroma rate following abdominoplasty, component separation, and facelifts and following latissimus flap and deep inferior epigastric artery perforator flap harvest. Objectives The aim of this study was to investigate the effects of PTS techniques and their impact on the seroma rate in body contouring flap procedures. Methods A retrospective review was performed of all patients undergoing a flap procedure (defined as any procedure that produces a dead space and subsequent susceptibility to seroma) by a single surgeon at a single institution over 3 years. All patients/procedures utilized PTS techniques, as is routine in the surgeon’s practice. No drains were used. Patient demographics and complications, including seroma, were tracked. Results A total of 441 flap procedures were performed in 351 patients over the 3-year study period. These procedures comprised 305 abdominoplasties, 68 lower body lifts, 17 medial thigh lifts, 36 brachioplasties, and 15 torsoplasties. PTSs were used in all procedures. No drains were utilized. Complications occurred in 72 procedures (16.3%), with the most common complication being minor wound dehiscence without infection. There were no cases of seroma. Conclusions PTSs represent an effective technique for reducing the seroma rate, eliminating the potential space and promoting tissue adherence in flap procedures for body contouring. This is the first study of its kind demonstrating the use and role of this technique in body contouring procedures beyond the scope of abdominoplasty. Level of Evidence: 4

BACKGROUND The internal mammary artery/vein (IMA/V) are commonly used recipients for free flap breast reconstruction, but requires costal cartilage resection and limits future use of the IMA. This study aimed to evaluate the feasibility of the thoracoacromial artery/vein (TAA/V) as recipients for deep inferior epigastric artery perforator (DIEP) flap breast reconstruction compared with using the IMA/V. METHODS Medical charts of patients who underwent free DIEP flap breast reconstruction using the TAA/V or the IMA/V as recipient vessels were reviewed. Patient and vessel characteristics, time for vessel preparation and anastomosis, and postoperative pain were compared between TAA/V and IMA/V groups. RESULTS Thirty-four patients were included; 12 in TAA/V group, and 22 in IMA/V group. There was no flap failure in both groups. There were statistically significant differences between TAA/V and IMA/V groups in vessel preparation time (10.9 ± 3.7 min vs. 24.1 ± 6.0 min, p

Objective The aim of the present study was to report a novel design of the chimeric deep inferior epigastric artery perforator flap (DIEP) to achieve dead space filling, Achilles tendon bridging, and skin resurfacing simultaneously with minimal donor‐site morbidity. Methods From September 2012 to May 2016, a retrospective study was carried out on six pediatric patients with composite soft tissue defects of the heel that were repaired with the chimeric DIEP flap. The chimeric flap design included a flap of the anterior sheath of the rectus, a block of rectus muscle, and a large skin paddle. All the parts were supplied by a common artery. After harvesting the flap, all element parts were inserted at the corresponding sites in a tension‐free manner. With one set of vessel anastomoses at the recipient site, accurate repair with tendon reconstruction, dead space elimination, and wound covering were accomplished. The donor site incisions were closed initially. Data on patient age, medical history, injury severity, defect size, flap dimensions, recipient vessels, donor site closure, complications, and follow‐up were collected and reviewed. Results Five of the six chimeric DIEP flaps survived without complications. The remaining one case experienced partial necrosis of the skin paddle caused by venous congestion, which healed after routine dressing changes. Primary donor site closure was accomplished in all cases. The mean follow‐up was 18.6 months (range, 10–36 months). Five patients had satisfactory aesthetic and functional outcomes; one patient needed a secondary debulking procedure. Compared to the unaffected side, the affected side showed no obvious difference for ankle movement, tiptoe function, and patient gait during the follow‐up period. Good ankle function was observed in all patients. There was no donor site breakdown, with only a slightly noticeable linear scar. Conclusion The chimeric DIEP flap reduced the operative time, solved the problem of deficiency of recipient vessels, and attained satisfactory functional and aesthetic outcomes with low donor site morbidity. Therefore, it is a promising option for three‐dimensional reconstruction of composite defects with dead space and Achilles tendon defects as well as skin loss in children., We reported a novel design of the chimeric deep inferior epigastric artery perforator flap (DIEP). The chimeric DIEP flap reduced the operative time, solved the problem of the deficiency of recipient vessels, and attained satisfactory functional outcomes. Therefore, it could be a promising option for three‐dimensional reconstruction of composite defects in children.

Introduction When a Deep Inferior Epigastric Artery flap is not suitable, the Profunda Artery Perforator (PAP) flap can be a good alternative for autologous breast reconstruction. Popularity of the PAP flap is expanding, but it is still only slowly being adopted worldwide. We report our experience with 116 consecutive PAP flaps showing refinements and evolution of the technique towards improvement in outcomes and patients' satisfaction. Methods We prospectively collected data from consecutive PAP flap breast reconstructions performed from 2016 to 2019. Patients' demographics, pre-, intra-, postoperative data and revision procedures were analyzed. The BREAST-Q and a specific questionnaire investigating outcomes at the donor site were completed preoperatively and 12 months postoperatively. Results One-hundred and sixteen PAP flaps were performed in 86 patients, 64 unilateral and 22 bilateral breast reconstructions. Mean body mass index was 24.72 kg/m2 (range 18.9-29.2) and mean flap weight was 251.30g (range 152g – 455g). Complications included donor site hematoma (1.7%), seroma (2.6%), fat necrosis (1.7%) and wound dehiscence (2.6%). No arterial/venous thrombosis nor flap losses were recorded. Patients reported high satisfaction in all BREAST-Q domains, with mean postoperative scores being higher than preoperative ones, suggesting a positive effect in quality of life and satisfaction. Scores were significant in the satisfaction with breast domain (p= 0.0016). Conclusions Breast reconstruction with PAP flap yields a high success, low complications and excellent cosmetic outcomes in the breast and donor sites. It improves patients' satisfaction and quality of life; hence it can be considered an excellent option for autologous breast reconstruction.

Extensive surgical removal is often required to treat soft tissue sarcomas. When they are localized in the groin-upper medial thigh region, the excision is particularly demanding because of the rich lymphatic network and lymph nodes present in that area. The lymphatic vessels with respective lymph nodes draining the whole leg are most of the time inevitably damaged, causing a series of debilitating sequelae such as lymphocele and lymphedema. To prevent these issues, together with the defect coverage, additional lymphovenous anastomoses (LVA) showed encouraging results. Here we present a case of resected groin sarcoma reconstructed by means of pedicled lower deep inferior epigastric perforator (DIEP) flap combined with multiple LVAs. In particular, the superficial veins of the DIEP flap have been employed as the donor veins for LVAs. A 76-year-old patient presented a leiomyosarcoma in the right trigonum femorale which was surgically excised leaving a defect of about 12 cm × 7 cm with exposed femoral vessels and nerves. The remaining defect was then filled with a pedicled DIEP flap, and three leaking lymphatic vessels in the thigh were anastomosed with three branches of a superficial vein originating from the DIEP flap. The postoperative course was uneventful and at 12 months follow-up no signs of either seroma or lymphocele. This result suggests that the concept of lymphatic flow-through (LyFT) DIEP flap might be a modern and particularly useful solution for those cases that require both dead space obliteration and lymphatic drainage restoration.

The gold standard for autologous reconstruction in the post-mastectomy patient remains the deep inferior epigastric artery perforator flap, although many women may not be candidates for abdominally based free tissue transfer. In this scenario, there are several other donor site options based from the thigh (transverse and diagonal upper gracilis flaps, profunda artery perforator flap, lateral thigh flap) and trunk (lumbar artery perforator flap, superior and inferior gluteal artery perforator flaps). This study will review the history, relevant anatomy, surgical technique and outcomes for alternative flaps in autologous reconstruction. Additionally, preoperative imaging (CTA, MRA) and novel applications (stacking flaps, neurotization) in breast reconstructive microsurgery will be discussed.

For survivors of breast cancer lymphedema is their greatest survivorship burden. Modern surgical techniques to treat lymphedema are effective at reducing limb volume, symptoms of lymphedema, episodes of cellulitis, and improving patient quality of life. Physiologic procedures, including lymphovenous bypass (LVB) and vascularized lymph node transplant (VLNT), restore physiological lymphatic function within the affected extremity. In patients with post-mastectomy breast cancer-related upper extremity lymphedema that desire breast reconstruction, microvascular abdominal flap breast reconstruction can be combined with superficial inguinal (groin) VLNT to provide breast reconstruction and treatment of lymphedema in a single operation. This article reviews the indications, preoperative assessment, surgical technique, outcomes, and tips and pearls for performing this procedure.

Reconstruction of a complex knee defect is challenging, especially when complicated with osteomyelitis. Complex knee defect requires multi-component three-dimensional reconstruction using a chimeric flap. Although anterolateral thigh (ALT) flap is the most workhorse chimeric flap, another chimeric flap is required when ALT flap is not available. In this report, we present a case of complex knee defect successfully treated with a free triple-component chimeric deep inferior epigastric artery perforator (DIEP) flap transfer. A 36 year-old male sustained right above-knee amputation and Gustilo IIIB open fracture of the left patella after being run over by a train. Stump formation was performed for the right limb amputation, and the left knee wound resulted in skin necrosis complicated with patella osteomyelitis. After debridement, the left knee wound showed a 3 × 2 cm articular capsule defect, 5 × 2 cm exposed patella stump, and a 16 × 9 cm skin defect. A triple-component chimeric DIEP flap, containing a 7 × 3 cm rectus abdominis muscle (RAM), a 3 × 2 cm RAM's fascia, and a 23 × 10 cm skin was transferred. The RAM's fascia was used to reconstruct the joint, the RAM to cover the exposed patella's stump and the reconstructed joint, and the skin paddle to cover the skin defect. Six months after the surgery, the patient could walk without osteomyelitis recurrence, and there was no limitation in the left knee joint's range of motion. Although indication is limited, a multi-component chimeric DIEP flap may be an option for three-dimensional reconstruction of a complex defect.

Complex abdominal wall reconstruction is challenging, and vascularized fascia is preferred for active infection cases. Pedicled tensor fascia lata flap is commonly used for lower abdominal wall reconstruction, and free vascularized fascial flap based on the lateral circumflex femoral artery (LCFA) is used for upper abdominal wall reconstruction. However, LCFA-based flap transfer requires invasive and time-consuming muscle dissection and a large recipient vessel. The purpose of this report was to present a new application of superficial circumflex iliac artery (SCIA) perforator (SCIP)-based fascial flap for upper abdominal wall reconstruction. A 70-year-old male suffered from a long-lasting extensive abdominal wall herniation complicated with mesh infection and cutaneous fistulae following multiple herniation repair with synthetic mesh. After complete debridement of infected tissues, there was a 29 x 26 cm full-thickness abdominal wall defect. Components separation was performed to minimize the defect size, after which 12 x 7 cm defect remained in the upper abdominal wall. A 20 x 10 cm SCIP deep fascial flap was elevated based on the deep branch of the SCIA. The SCIP flap was transferred to the defect to reconstruct the upper abdominal wall. The SCIP was anastomosed to the deep inferior epigastric artery perforator with supermicrosurgical perforator-to-perforator anastomosis. Postoperative course was uneventful with good functional and esthetic results of the donor and recipient sites 11 months after the surgery. Although further studies are required, SCIP fascial flap may be an option for upper abdominal wall reconstruction.

Objectives: The upper extremity is an important functional unit and is frequently exposed to trauma. Large soft tissue defects in the upper extremities require reconstruction with reliable tissues with maximum functional and aesthetic results.We aimed to present a reconstruction a massive soft tissue defect of elbow with oblique paraumbilical perforator flap in a multitrauma patient. Methods: A 26 year-old female patient was admitted as a result of an in-vehicle traffic accident. The patient had cerebral contusion, lung contusion, humerus fracture, tibia fracture, large dermal abrasions in the trunk,extensive tissue defect including scalp, wrist, elbow and proximal forearm. After reduction of fractures,ulnar nerve was reconstructed with sural nerve graft. 22 x 17 cm sized massive soft tissue defect of the elbow was. Results: Based on two deep inferior epigastric artery perforators the OPUP flap was raised in suprafascial fashion. The flap was divided on the 22nd day. No complications observed postoperatively. Conclusion:The OPUP flap is a versatile and reliable flap; hence it can be used as a salvage option for massive upper extremity defects around the elbow especially when other reconstructive methods are not possible.

Extensive soft tissue loss or injury of the hand and upper extremity is a challenging reconstructive problem traditionally treated with abdominal-based pedicled flaps. Options for coverage included the groin flap based on the superficial circumflex iliac artery, the Scarpa's fascia flap based on the superficial inferior epigastric artery, and the paraumbilical perforator flap from the deep inferior epigastric artery perforators. Despite the ability to provide consistent and pliable soft tissue coverage with ease of elevation, these flaps have several disadvantages including restriction of mobility, requirement for multiple procedures, bulkiness and patient discomfort. With the advent of microsurgery, pedicled regional flaps, and off-the-shelf skin substitutes, the applications for these flaps have narrowed. However several indications still remain. These include: patient and facility factors which deter microsurgery, the absence of recipient vessels after injury, prior surgical use of recipient vessels, the need to preserve major vessels for future reconstruction, and large multi-surface wounds requiring coverage. In this review we detail these indications and provide case examples for each.

INTRODUCTION Venous congestion is the most common vascular complication of the deep inferior epigastric artery perforator (DIEP) flaps. Adding a second venous drainage by anastomosing a flap vein and a recipient vein (super-drainage) is considered the solution of choice. Evidence to support this procedure, had not yet been confirmed by an analysis of the literature. We aimed to provide this evidence. MATERIALS AND METHODS We searched the literature (MedLine, Scopus, EMBASE, Cochrane Library, and Google Scholar), for studies discussing venous congestion and venous super-drainage in DIEP flap for breast reconstruction. Thirteen of the 35 articles compared results between one or two venous anastomoses. Meta-analysis was performed following PRISMA guidelines. Pooled risk ratio (RRs) for congestion, fat necrosis, partial necrosis, and total necrosis with corresponding 95% confidence intervals (CI) were calculated using a fixed-effect model with the Mantel-Haenszel method. The need to return to surgery (95% CI) was estimated with a random effect model using the DerSimonian and Liard method. RESULTS We showed a statistically significant advantage of super-drainage to reduce the venous congestion of the flap (RR: 0.12, 95% CI: 0.04-0.34, p-value

Background: The deep inferior epigastric artery perforator (DIEP) flap is the gold standard in autologous breast reconstruction. When the abdomen is not available, alternative donor sites can be found at the buttock, the lumbar region, or the thighs. These flaps are referred to as second-choice flaps. This study compares the superior gluteal artery perforator (SGAP) flap and the lumbar artery perforator (LAP) flap to the DIEP flap using patient-reported outcomes. Methods: A retrospective study was performed reviewing the records of 417 women who underwent a free flap breast reconstruction with either a DIEP, an LAP, or an SGAP flap, between 2006 and 2018. Patients were asked to fill out the BREAST-Q questionnaire, and patient-reported outcomes were analyzed and correlated to the demographic information. Results: The response rate was 54.5 percent, with 50 LAP, 153 DIEP, and 25 SGAP flap patients participating. When questioned about their satisfaction with breasts and satisfaction with outcome, all three procedures were rated similarly high. When comparing the physical well-being of the donor site and appearance of the donor site, LAP flap patients reported significantly lower scores than DIEP and SGAP flap patients. Conclusions: Patients who undergo LAP or SGAP flap breast reconstruction seem similarly satisfied with the appearance and outcome of their free flap breast reconstruction compared with DIEP flap patients. The donor-site morbidity and its impact on the patient's well-being in SGAP and LAP flap patients have been underestimated. Despite more donor-site discomfort, the LAP and SGAP flaps are feasible alternatives whenever the DIEP flap is not possible.

Background Several patient-related factors have been identified with regard to the safety and efficacy of breast reconstructions. Using the largest database available in Europe, the presented study investigated the impact of cigarette smoking on deep inferior epigastric artery perforator (DIEP) free-flap breast reconstructions. Methods In total, 3,926 female patients underwent 4,577 free DIEP-flap breast reconstructions after malignancies in 22 different German breast cancer centers. The cases were divided into two groups: nonsmokers (NS) and smokers (S). Impact of smoking on surgical complications, controlled for covariates, and cluster effects within the cancer centers were analyzed by using generalized linear mixed models. Results Overall, there was no significant difference between the groups of patients regarding the rate of total flap loss. However, the rate of partial flap loss (0.9 vs. 3.2%, p Conclusion Our findings suggest that successful free tissue transfer can be achieved in smokers despite higher rates of partial flap losses and wound-healing disturbances. However, patients with a history of smoking requiring DIEP flap reconstruction should be critically evaluated preoperatively, informed in detail about the higher risk of complications and encouraged to quit smoking prior to surgery.

Background The deep inferior epigastric artery perforator (DIEP) flap is the commonest flap used for breast reconstruction after mastectomy. It is performed as a unilateral (based on one [unipedicled] or two [bipedicled] vascular pedicles) or bilateral procedure following unilateral or bilateral mastectomies. No previous studies have comprehensively analyzed analgesia requirements and hospital stay of these three forms of surgical reconstruction. Methods A 7-year retrospective cohort study (2008–2015) of a single-surgeon’s DIEP-patients was conducted. Patient-reported pain scores, patient-controlled morphine requirements and recovery times were compared using non-parametric statistics and multivariable regression. Results The study included 135 participants: unilateral unipedicled (n=84), unilateral bipedicled (n=24) and bilateral unipedicled (n=27). Univariate comparison of the three DIEP types showed a significant difference in 12-hour postoperative morphine requirements (P=0.020); bipedicled unilateral patients used significantly less morphine than unipedicled (unilateral) patients at 12 (P=0.005), 24 (P=0.020), and 48 (P=0.046) hours. Multivariable regression comparing these two groups revealed that both reconstruction type and smoking status were significant predictors for 12-hour postoperative morphine usage (P=0.038 and P=0.049, respectively), but only smoking, remained significant at 24 (P=0.010) and 48 (P=0.010) hours. Bilateral reconstruction patients’ mean hospital stay was 2 days longer than either unilateral reconstruction (P Conclusions Although all three forms of DIEP flap breast reconstruction had similar postoperative pain measures, a novel finding of our study was that bipedicled DIEP flap harvest might be associated with lower early postoperative morphine requirements. Bilateral and bipedicled procedures in appropriate patients might therefore be undertaken without significantly increased pain/morbidity compared to unilateral unipedicled reconstructions.

Background The purpose of this study was to compare the anatomical features of the internal mammary vessels (IMVs) at the second and third intercostal spaces (ICSs) with regard to their use as recipient vessels in deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. Methods A total of 38 consecutive DIEP breast reconstructions in 36 patients were performed using IMVs as recipient vessels between March 2017 and August 2018. The intraoperative findings and postoperative complications were analyzed. Anatomical analyses were performed using intraoperative measurements and computed tomography (CT) angiographic images. Results CT angiographic analysis revealed the mean diameter of the deep inferior epigastric artery to be 2.42±0.27 mm, while that of the deep inferior epigastric vein was 2.91±0.30 mm. A larger mean vessel diameter was observed at the second than at the third ICS for both the internal mammary artery (2.26±0.32 mm vs. 1.99±0.33 mm, respectively; P=0.001) and the internal mammary vein (IMv) (2.52±0.46 mm vs. 2.05±0.42 mm, respectively; P Conclusions The IMVs at the second ICS had more favorable anatomic features for use as recipient vessels in DIEP flap breast reconstruction than those at the third ICS.

Background The superficial circumflex iliac artery perforator (SCIP) flap cannot be used for coverage of large defects. We introduce a novel flap design to overcome the SCIP flap's size limitation. Methods Data of patients who underwent coverage of defects exceeding 113 cm2 (12 × 12 cm) using combined flaps composed of an SCIP flap and either a superficial inferior epigastric artery (SIEA) flap or a deep inferior epigastric artery perforator (DIEP) flap from September 2015 to September 2019 were retrospectively reviewed. After elevation of the SCIP flap, the SIEA was dissected. If the diameter of the SIEA was smaller than 0.5 mm, a DIEP included in the flap design was identified. For minimal donor site morbidity, the DIEP dissection was limited to its takeoff point from the deep inferior epigastric artery (DIEA), and a small T-portion of the DIEA was harvested. Results Six patients met inclusion criteria. The average defect size was 18.5 ± 2.3 × 15.7 ± 3.7 cm, and all defects were sufficiently covered. The mean dimensions of the SCIP flap, the SIEA flap, and the DIEP flap were 18.5 ± 2.5 × 7.5 ± 1.0 cm, 15.5 ± 2.1 × 6.6 ± 1.6 cm, and 17.5 ± 2.1 × 6.5 ± 0.7 cm, respectively. All flaps survived completely with no healing complications, and no donor site complications were observed. The SCIP flap was combined with the SIEA flap in four cases and with the DIEP flap in two cases. The average follow-up period was 12.7 ± 6.7 months. The final outcome was satisfactory in all cases. Conclusion Large defects (up to 20 × 20 cm) can be covered with minimal donor site morbidity, with primary closure, by combining either the SIEA or the DIEP flap with the SCIP flap.

As deep inferior epigastric artery perforator (DIEP) flap surgery is gaining popularity, more patients including BRCA-positive patients need simultaneous laparoscopic surgery. We share our experience on a patient who underwent concurrent laparoscopic hysterectomy during flap elevation with a novel method. A patient diagnosed with a right breast cancer also required laparoscopic hysterectomy due to multiple uterine myoma. After perforator mapping was performed, flap elevation through external oblique fascia level was carried out first, sparing the periumbilical perforator and superficial inferior epigastric vein. Three ports were inserted for laparoscopy on posterior fascia level in the periumbilical area, left upper quadrant area and suprapubic area. The surgery was completed without any complication, gas leaks or vascular injury with the advantage of reduced risk of vascular damage and less surgical incision.

Background Total extraperitoneal laparoscopically assisted harvest of the deep inferior epigastric vessels permits a decrease in myofascial dissection in deep inferior epigastric artery perforator flap breast reconstruction. The authors present a reliable technique that further decreases donor-site morbidity in autologous breast reconstruction. Methods The authors conducted a retrospective cohort study of female subjects presenting to the senior surgeon (S.K.K.) from March of 2018 to March of 2019 for autologous breast reconstruction after a newly diagnosed breast cancer. The operative technique is summarized as follows: a supraumbilical camera port is placed at the medial edge of the rectus muscle to enter the retrorectus space; the extraperitoneal plane is developed using a balloon dissector and insufflation; two ports are placed through the linea alba below the umbilicus to introduce dissection instruments; the deep inferior epigastric vessels are dissected from the underside of the rectus muscle; muscle branches and the superior epigastric are ligated using a Ligasure; and the deep inferior epigastric pedicle is ligated and the vessels are delivered through a minimal fascial incision. The flap(s) is transferred to the chest for completion of the reconstruction. Results Thirty-three subjects totaling 57 flaps were included. All flaps were single-perforator deep inferior epigastric artery perforator flaps. Mean fascial incision length was 2.0 cm. Sixty percent of subjects recovered without narcotics. Mean length of stay was 2.5 days. Flap salvage occurred in one subject after venous congestion. Two pedicle transections occurred during harvest that required perforator-to-pedicle anastomosis. Conclusion Total extraperitoneal laparoscopically assisted harvest of the deep inferior epigastric pedicle is a reliable method that decreases the donor-site morbidity of autologous breast reconstruction.

Perforator-based flaps have become a mainstay of autologous breast reconstruction practice. Despite available radiological investigations ranging from Doppler ultrasound (US) to CT angiography (CTA), finding and quantitatively assessing perforators remains a time-consuming, complex process. Infrared thermographic imaging (IRT) shows promise as a novel modality for preoperative localisation of perforator vessels. Thirteen women undergoing elective breast reconstruction with deep inferior epigastric artery perforator (DIEAP) flaps were recruited between August 2017 and July 2018. All had CTA and Doppler US mapping of arterial perforators preoperatively as standard. Additional abdominal thermal images were taken using a FLIR ONE smartphone compatible camera. Thermal hotspots were compared with Doppler markings and CTA findings. Twenty-six flaps were analysed. Seventy perforators were marked by Doppler US, with a mean of 2.92 perforators per flap (± SEM 0.15, SD 0.72). Forty (57%) had a corresponding hotspot on IRT. Overall, there was a statistically significant positive correlation between the number of perforators detected by Doppler US and IRT (r = 0.573, n = 26, p = 0.003) and kappa index 0.65. Eighty-four perforators were identified by CTA, with a mean of 3.5 perforators per flap (± SEM 0.14, SD 0.66). Fifty-eight (69%) had a corresponding hotspot on IRT. There was a statistically significant positive correlation between the number of perforators detected by CTA and IRT (r = 0.504, n = 26, p = 0.012) and kappa index 0.60. Thermography is an inexpensive, portable, non-invasive imaging technique, which shows statistically significant correlation to CTA and Doppler US in mapping perforators.

Objectives. Lower extremity ulcers are quite common in patients with autoimmune diseases. Due to chronic use of immunosuppressants, these wounds may develop into deeper wounds resulting in exposure of bone or tendon, which in turn may require free tissue transfers for coverage. The author reviewed perforator free flap transfers performed in this group of patients and analyzed the results. Methods. A retrospective review was performed on all patients who underwent perforator free flap transfer for coverage of lower extremity ulcers without trauma, over a 10-year period. Patient demographics, administered immunosuppressants, and flap and donor site complications were analyzed. Results. Twenty-two perforator free flap transfers were performed in patients with autoimmune diseases, including 18 thoracodorsal perforator flaps, 2 anterolateral thigh flaps, and 2 deep inferior epigastric artery flaps. There was no total flap loss, but there was a high rate of partial flap necrosis (40.9%) and wound dehiscence (40.9%). Intake of corticosteroids was significantly associated with postoperative complications ( P < .05). Conclusion. As partial loss of flap and wound dehiscence is much more common in this group of patients, treatment may take longer, and a fully informed consent should be obtained preoperatively. Surgeons should not avoid performing perforator free flap transfers in patients with autoimmune diseases under immunosuppression; instead, much more preparation and caution are required.

The deep inferior epigastric artery perforator (DIEP) flap has been widely used for approximately 30 years as an effective method for breast reconstruction, defect repair, and perineal reconstruction. However, few literatures have reported on thinned pedicle DIEP flaps for scrotal reconstruction. The present study presents a series of reconstruction of the scrotum using thinned pedicle DIEP flaps. Five patients with large scrotal skin defects were admitted to our hospital from October 2010 to December 2015. Among these patients, three patients had testes and spermatic cord exposure after accidental injury, while two patients had testes exposure after machine extrusion. All of these patients were repaired using thinned pedicle DIEP flaps. During the 12–24-month follow up, one patient experienced a bulky flap, and a subsequent thinned flap was successfully made. The other four flaps were successfully transplanted with good esthetic and functional results. All donor sites were primarily closed; there was no functional disturbance, such as dysuria and abdominal hernia, and the sensation of these flaps partially recovered after 6 months. The thinned pedicle DIEP flap is robust, reliable, and resilient, and offers good-quality skin cover and cushion to the testes. This flap can be considered a good choice for scrotal reconstruction.

Background Reconstruction of intrapelvic soft tissue defects traditionally relies on regional pedicled myocutaneous flaps. However, there remain situations in which local options are unavailable. We review our experience treating intrapelvic defects with the anterolateral thigh (ALT) microvascular free flap. Methods A retrospective, institutional review was conducted from 2014 to 2018 of patients undergoing microvascular ALT flap reconstruction of intrapelvic defects. Four patients were identified in this cohort out of 92 total pelvic reconstruction cases. Results All patients underwent abdominoperineal resection (APR) for rectal cancer treatment. In the two male patients, pelvic abscesses and bladder leak necessitated soft tissue reconstruction after radiation and APR. In both, regional tissue options were unavailable, and a buried ALT free flap was used for soft tissue reconstruction. Both female patients developed rectovaginal fistulas secondary to their tumor burden, necessitating posterior vaginal wall resections. Prior surgical scars and ostomies made abdominal wall tissue unavailable; thus, free ALTs were used to eliminate intrapelvic dead space and reconstruct the posterior vaginal wall. In all cases, recipient vessels were the deep inferior epigastric artery and vein. Flap survival was 100%. Conclusions Pelvic reconstruction has traditionally been addressed with local/regional pedicled flaps. In cases where these are unavailable, the free ALT flap is a versatile option when buried for intrapelvic reconstruction or posterior vaginal wall lining. We also propose updating Cordeiro et al.'s classic vaginal defect reconstruction algorithm to include the free ALT flap for type IB cases in which the rectus abdominis is unavailable.

Background Phalloplasty often requires free tissue transfer. There is ample literature describing flap-related outcomes, but the microsurgical technique used, including choice of recipient vessels, has been an overlooked yet important topic. In this study, the authors review the outcomes of their experience with the deep inferior epigastric artery and locoregional veins and outline technical modifications that occurred during the study period. Methods A retrospective chart analysis of patients who underwent microsurgical phalloplasty between September of 2016 and July of 2019 was performed. Variables included flap design, donor site, and recipient vessels. The outcome measures were return to the operating room for flap compromise and partial or complete flap loss. Results Forty-two phalloplasties using the deep inferior epigastric artery were identified. There were six take-backs for flap compromise, and four patients required venous revision, one of whom lost his urethral flap on postoperative day 9. There was a decrease in take-back rate from 30 percent in the first 20 patients to 0 percent in the second 22 patients in the study period. A total of 11.9 percent of patients had partial flap loss. This decreased from 15 percent to 9 percent in the two groups. Conclusion After an initial learning curve, the combination of deep inferior epigastric artery, deep inferior epigastric vein, and great saphenous vein combined with specific technical modifications such as targeted coagulation of the vasa nervorum of the clitoral nerve has proven to be a reliable technique.

Background This study aims to characterize the effect of laser-assisted indocyanine green fluorescence angiography on fat necrosis and flap failure in deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. Methods A retrospective review was performed on 1000 free flaps for breast reconstruction at a single center from 2010 to 2017. Indocyanine green angiography was used after completion of recipient-site anastomoses to subjectively assess for areas of hypoperfusion. A multivariable logistical analysis was conducted with 24 demographic and surgical factors and their effects on fat necrosis and flap failure. Results Five hundred six DIEP flaps were included in the statistical analyses. Thirteen percent of flaps had fat necrosis. Indocyanine green angiography was used for 200 flaps and was independently associated with a decrease in the odds of fat necrosis (OR, 0.38; p = 0.004). There was no reduction in flap failure rates when using indocyanine green angiography (OR, 1.15; p = 0.85). However, there was a decrease in flap loss with increasing venous coupler diameter (OR, 0.031 per 1-mm increase; p = 0.012). The 84.9-g higher weight of resected tissue before inset without indocyanine green angiography versus the weight of the tissue resected with indocyanine green angiography was statistically significant (p = 0.01). Per single incident of fat necrosis, our cohort underwent an additional 0.69 revision procedures, 1.22 imaging studies, 0.77 biopsies, and 1.7 additional oncologic office visits. Conclusion Intraoperative indocyanine green fluorescence angiography decreases the odds of fat necrosis, saves volume when flap trimming at inset, and can significantly reduce the postoperative surveillance burden in DIEP-based breast reconstruction.

The aim of the study was to investigate the relationship of BMI and abdominal wall thickness (AWT) with the diameter of the dominant deep inferior epigastric artery perforator (DIEP) as well as DIEA branching pattern in preoperatively performed computed tomography angiography (CTA).We conducted a retrospective study including all patients undergoing DIEP flap breast reconstruction with available CTAs from November 2013 to April 2018 in our department. The caliber-strongest DIEP was detected after passage of the rectus fascia as well as the superficial inferior epigastric artery (SIEA) and correlated with the AWT 5 cm above and below the umbilicus, lateral at the level of the umbilicus and at the level of the anterior superior iliac spine (ASIS), and with BMI.Seventy-seven patients met the inclusion criteria (age: 47.3 ± 8.9 years). We observed a significant relationship (p 0.05) between DIEP (mean ∅ = 2.98 mm) and BMI (r = 0.353), the AWT supra- and infraumbilical (r ≥ 0.32), and the AWT lateral at the level of the umbilicus and ASIS (r ≥ 0.25). In addition, there was a highly significant correlation (p 0.01) between SIEA and BMI (r = 0.389) and between the AWT lateral at the level of ASIS (r ≥ 0.41).We demonstrated a correlation of the diameter of the dominant DIEP with both BMI and AWT. Focusing on the diameter, in patients with a high AWT at the level of the ASIS, the SIEA, if present, may represent an alternative therapeutic option.

SUMMARY One key component of a successful autologous breast reconstruction is insetting the flap to accurately resemble an aesthetic breast. The authors describe a novel technique used to shape a deep inferior epigastric artery perforator flap into a coned breast mound before introducing it into the breast pocket. With the flap perfusing on the chest wall, an area of skin estimating the size and location of the skin paddle is marked. The skin to be buried is then deepithelialized. Once hemostasis is ensured, the shaping is performed. Two 2-0 polydioxanone sutures are anchored in the Scarpa fascia at the 10- and 2-o'clock positions and then run at the level of the Scarpa fascia to the 6-o'clock position. The two sutures are then cinched together to achieve the desired shape and then tied. The flap is then placed in the breast pocket and secured into place at the inferomedial and inferolateral corners, and at its cranial aspect. The size of the skin paddle can then be finalized. In the authors' series of 21 breast reconstructions in 11 patients using flap preshaping, they have not seen any compromise in flap perfusion, with one patient showing a small area of secondary fat necrosis. In addition, the flaps maintained their aesthetic breast shape throughout follow-up. The authors believe this technique for shaping inferior epigastric artery perforator flaps before inset into the breast pocket to be both safe and predictable, simplifying one of the more tedious aspects of autologous breast reconstruction.

Background Abdominal flap-based breast reconstruction is challenging in the overweight and obese population not only because of increased donor-site complications, but also because excessive flap thickness makes inset cumbersome, requiring thinning and remodeling that frequently result in aesthetically poor outcomes. Methods The authors started by studying 10 deep inferior epigastric artery perforator flaps with angiographic computed tomography. Then, they prospectively performed 21 breast reconstructions using a superficial thinning technique reliant on a constant suprafascial vessel as the pedicle for the remaining deep fat and compared the rate of complications with their previous experience using traditional flap thinning techniques. Results All samples studied showed a suprafascial division of the main perforator. Two constant branches were identified, one coursing over the Scarpa fascia and displaying a robust network of linking vessels with the subcutaneous and subdermal plexuses. That anatomical insight was used to develop a flap-thinning technique tested on 21 consecutive high-body mass index patients. A 7-year retrospective analysis (n = 164) showed no significant correlation between body mass index and incidence of complications except for a long-term upper pole step deformity that was associated with increasing body mass index (p = 0.001). No statistically significant difference in complications was found comparing high-body mass index patients from the retrospective group (n = 72) with the superficial thinning group, but a highly suggestive difference (p = 0.061) was found regarding the avoidance of the step deformity using the superficial thinning technique. Conclusion The presence of a constant suprafascial perforator branch makes superficial DIEP thinning a safe technique that facilitates inset and improves the reconstructed breast contour of obese patients.

BACKGROUND Intraoperative venous congestion is a main complication in deep inferior epigastric artery perforator (DIEP) flap for breast reconstruction. We present a pedicle measuring technique to precisely predict the length of pedicle needed in DIEP free flap, to improve the outcome, and to reduce the risk of donor site morbidity and complications. MATERIALS AND METHODS A single-center, open-label, prospective, randomized study was carried out to access efficacy and safety of a pedicle measuring technique in 389 patients. Each patient received a delayed breast reconstruction using free unipedicled DIEP flap, and internal mammary vessels were chosen as recipient vessels. During the surgery, the conventional DIEP flap technique was used in the control group, in which the course of the pedicle was fully dissected. In the measuring group, the flap in setting way was decided preoperatively, the distance (A) between the internal mammary vessels (a) and the point of DIEP perforator into the subcutaneous tissue (b) was measured, and then the length (B) of the perforator (c) and the main trunk (d) is measured and dissected to achieve 1 cm longer than A. RESULTS There are 180 and 209 patients enrolled in the control and measuring group, respectively. Venous congestion occurred in 15 patients (8.3%) in the control group, and 1 patient (0.5%) in the measuring group (P < 0.001). All the 16 patients were found venous thrombosis. Then successful free flap salvage surgeries were performed in 10 patients. Six patients (3.3%) had total flap necrosis due to recurrent venous thromboembolisms. Fat necrosis occurred in 16 patients (8.9%) in the control group, and 5 patients (2.4%) in the measuring group (P = 0.006). Partial flap necrosis was found in 12 patients (6.7%) in the control group, and in 3 patients (1.4%) in the measuring group (P = 0.008). Total flap necrosis occurred in 6 patients (3.3%) in the control group, but no (0%) patient in the measuring group (P = 0.009). CONCLUSIONS Measurement of pedicle length for DIEP flap transferring in breast reconstruction is a reliable technique that could secure the DIEP free flap, reduce operative invasiveness, and lower the risk of complications considerably.

Background The superficial fascial system is routinely closed to alleviate tension at the abdominal donor site after harvest of the deep inferior epigastric artery perforator flap (DIEP) for breast reconstruction. This is thought to decrease rates of wound dehiscence and improve contour postoperatively. There has been no comparative analysis on closure of the superficial fascial system and its effect on donor-site outcomes. Methods The authors retrospectively evaluated outcomes of DIEP flap breast reconstructions performed between 2017 and 2019. After May of 2018, the surgeons collectively agreed to stop closure of the superficial fascial system. All subsequent patients underwent closure of rectus abdominis fascia followed by skin closure. Patient demographic data and abdominal donor-site comorbidities were recorded between the superficial fascial system closure and no-superficial fascial system closure groups. Representative photographs of patients from the two groups were blindly assessed for scar appearance and contour using previously published grading scales. The results were compared. Results DIEP flap breast reconstruction was performed in 103 consecutive women. Among patients with abdominal donor-site reconstruction, 66 had superficial fascial system closure and 37 did not. There was not a significant difference in fat necrosis or wound dehiscence between the two groups (p = 0.29 and p = 0.39, respectively). Postoperative abdominal scar and contour were evaluated by 10 independent raters and showed no significant difference between the two groups. Conclusion Omission of superficial fascial system closure resulted in no difference in wound dehiscence or fat necrosis rates and aesthetic appearance of the abdominal scar and contour.

Background The first reports of using color Doppler ultrasound for evaluation of the microvasculature were in the 1990s. Despite the early reports of its efficacy, color Doppler ultrasound did not achieve popularity nor general usage in part due to the cumbersome size, cost and poor resolution. This is the first study to demonstrate the potential utility of a new, highly portable, tablet-based color Doppler ultrasound (PT-CDU) system for imaging perforator flaps. Methods The deep inferior epigastric artery (DIEP), lateral arm (LA), anterolateral thigh (ALT), thoracodorsal artery (TDAP), and the medial sural artery (MSAP) perforator flaps were imaged within classic topographic landmarks to visualize and measure variables related to perforator flap anatomy. The Philips Lumify L12–4 linear array probe attached to the Samsung Galaxy Tab A tablet was the system used for all examinations. Results A total of 216 flaps were scanned in 50 healthy adult volunteers: 44 DIEP, 44 LA, 40 ALT, 48 TDAP, and 40 MSAP. Precise anatomic information regarding perforator size, number, and location was obtained. Overall, the percent of flaps having at least 1 perforator within the specified topographical landmarks was 89% for the DIEP, 84.1% for the LA, 72.5% for the ALT, 50% for the TDAP, and 30% for the MSAP (p = 2.272e-09). The percent of patients having an asymmetry (right versus left) in the number of perforators was 72.7% (ALT), 65% (DIEP), 59.1% (LA), 41.7% (TDAP), and 30% (MSAP) (p = 0.0351). Conclusion Portable, tablet-based color Doppler ultrasound offers high-resolution images of perforators and represents a facile technology that may be of interest to microsurgeons in the planning of perforator flaps. Variations in vascular anatomy were well-demonstrated. This surgeon-driven imaging technology may represent an excellent alternative to other imaging modalities.

Background The lumbar artery perforator flap is a second-choice flap in autologous breast reconstruction whenever a deep inferior epigastric artery perforator (DIEP) flap is not possible. Ideal candidates are pear-shaped women who do not have enough bulk on the abdomen or thighs. Patient-reported “satisfaction with breasts” is excellent but we were curious about the donor site morbidity. Methods We performed a retrospective study of all lumbar flap breast reconstructions performed between 2010 and 2019. Patients were invited by e-mail and telephone to take part in a BREAST-Q survey. Results One hundred fifty-four flaps were performed in 110 patients. Sixty-three patients filled out the BREAST-Q questionnaire. The most frequently observed donor site complications are seroma (35.1%), dehiscence (8.4%), and hematoma (3.2%). Correction of the donor site scar was performed in 31.8% of patients, lipofilling of the donor flank in 5.2%, and liposuction of the contralateral flank in 18.3% of patients. Body mass index (BMI) was the only significant risk factor for donor site complications. Patient-reported “satisfaction with donor site appearance” was good but significantly lower for primary reconstructions compared with secondary and tertiary procedures. Flap weight significantly influences patient-reported “physical wellbeing of the donor site.” Ninety-seven percent of patients would recommend the surgery to someone in a similar position and would do it all over. Conclusion The lumbar artery perforator flap is a good alternative for breast reconstruction in selected patients. The donor site issues consist mainly of seromas, prolonged discomfort, and a scar that might be noticeable to others, but patient-reported satisfaction is very high.

SUMMARY Deep inferior epigastric artery perforator (DIEP) flap surgery is one of the most common techniques for breast reconstruction using abdominal tissue. Although the DIEP flap reduces donor-site morbidity when compared with the conventional free transverse rectus abdominis musculocutaneous flap, violation of the anterior rectus sheath, rectus muscle, and motor nerves cannot be avoided. To further minimize tissue damage in the donor site, the use of a surgical robotic system for DIEP flap harvest with a totally extraperitoneal approach has been suggested. This totally extraperitoneal approach has a long learning curve because of the narrow preperitoneal space and the difficulty of converting a potential space to an actual space. Thus, the authors suggest a single-port robotic system optimized for narrow surgical spaces as a feasible option for DIEP flap harvest by a totally extraperitoneal approach, which has a shorter learning curve.

Breast reconstruction using a pedicled transverse rectus abdominis muscle (TRAM) flap is a well-established surgical procedure. Although studies suggest that transplanting this flap using a delayed method reduces the risk of partial flap necrosis, challenges persist. Hence, we present three cases of breast reconstruction using a pedicled TRAM flap with both delaying and supercharging. Patient age, excised tissue volume for mastectomy, and follow-up period were as follows: Case 1, 58 years, 429 cm(3), 5 months; Case 2, 35 years, 910 cm(3), 6 months; and Case 3, 56 years, 489 cm(3), 4 months. One patient (Case 2) required a large flap tissue volume to achieve breast symmetry, whereas the other two (Cases 1 and 3) had long, longitudinal scars from previous cesareans sections. In a delayed surgery, the flap was partially elevated with partial dissection and no ligation of the deep inferior epigastric artery and vein (DIEAV). An artificial dermis with a silicone membrane (Teldermis(®)) was used to prevent adhesion of the rectus abdominal muscles and DIEAV to the surrounding tissue. Supercharging was performed by anastomosis between the ipsilateral DIEAV and internal thoracic AV. Flaps in zones I–III and in half of zone IV for Case 2, and zones I–III for Cases 1 and 3, were transferred; all survived without infection. This method allowed the transferring of a larger tissue volume compared with the conventional pedicled TRAM flap-transfer method. Thus, it may be useful for patients who require larger tissue volume or high-risk patients.

Background Advancements in three-dimensional (3D) printing have enabled production of patient-specific guides to aid perforator mapping and pedicle dissection during abdominal flap harvest. We present our early experience using this tool to navigate deep inferior epigastric artery (DIEA) topography and evaluate its impact on operative efficiency and clinical outcomes. Patients and Methods Between January 2013 and December 2018, a total of 50 women underwent computed tomographic angiography (CTA)-guided perforator mapping prior to abdominal flap breast reconstruction, with (n = 9) and without (n = 41) 3D-printed vascular modeling (3DVM). Models were assessed for their accuracy in identifying perforator location and source-vessel anatomy, as determined by operative findings from 18 hemi-abdomens. The margin of error (MOE) for perforator localization using 3DVM was calculated and compared with CTA-derived measurements for the same patients. Flap harvest times, outcomes, and complications for patients who were preoperatively mapped using 3DVM versus CTA alone were analyzed. Results Overall, complete concordance was observed between 3DVM and operative findings with regards to perforator number, source-vessel origin, and DIEA branching pattern. By comparison, CTA interpretation of these parameters inaccurately identified branching pattern and perforator source-vessel origin in 28 and 33% of hemi-abdomens, respectively (p = 0.045 and p = 0.02). Compared with operative measurements, the average MOE for perforator localization using 3DVM was significantly lower than that obtained from CTA alone (0.81 vs. 8.71 mm, p Conclusion The results of this study support the accuracy of 3DVM for identifying DIEA topography and perforator location. Application of this technology may translate to enhanced operative efficiency and fewer perfusion-related complications for patients undergoing abdominal free flap breast reconstruction.

The deep inferior epigastric artery perforator (DIEP) flap is the gold standard for autologous breast reconstruction. When the DIEP pedicle is damaged, alternative perforator flaps are harvested from sites with less donor tissue, such as the thigh. Pedicled superior epigastric artery perforator (SEAP) flaps have been recently described for reconstruction of inferior partial breast defects. The purpose of this report is to show the surgical technique of the free SEAP flap for reconstruction of the entire breast in two patients. The authors describe two patients where the DIEP pedicle was unavailable. The first patient was 53 years old, with body mass index (BMI) 22.7, while the second patient was 60 with BMI 32.4. The donor site was marked as for a DIEP, and two lateral row perforators were selected in each case. Flaps were designed to cross the midline, with adequate perfusion confirmed via indocyanine green angiography. Both flaps were rotated 90° counterclockwise for inset into the chest. Flap size and weight for the two patients were: 24 × 15 cm and 350 g; and 25 × 15 cm and 400 g. Both patients had a routine postoperative course without complications. Length of follow-up was 155 and 158 days, respectively. We believe that the free SEAP flap is a promising technique in select patients who require an alternative to the DIEP for autologous breast reconstruction.
