This case report presents the use of the superficial circumflex iliac perforator (SCIP) flap for soft tissue reconstruction of the knee, using the descending genicular artery (DGA) as the recipient vessel. A 14-year-old female table-tennis player presented with a right knee mass diagnosed as angiomatoid fibrous histiocytoma. Following resection of the mass, which left a 6.5 × 5.5 cm soft tissue defect over the patella, a free SCIP flap was harvested and used for reconstruction. The SCIP flap was chosen for its thinness and flexibility, making it suitable for the highly mobile knee joint. The superficial circumflex iliac artery (1.2 mm) was anastomosed to the DGA (1.5 mm) in an end-to-end fashion. The flap and deepithelialized skin paddle were routed through a subcutaneous tunnel, and the donor site was closed directly over a drain. The flap survived completely with no postoperative complications. Six months later, despite hyperpigmentation of the scar, the contour was satisfactory with no limitations in knee range of motion. This case underscores the advantages of the SCIP flap, particularly its compatibility with the DGA, reduced donor site morbidity, and excellent aesthetic and functional outcomes. The SCIP flap, combined with the DGA as the recipient vessel, provides an effective solution for complex knee reconstructions, offering a primary option for similar cases., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Autologous breast reconstruction using the abdominal flap based on the superficial system has the potential to minimize donor-site morbidity. Although efforts to improve its transfer have been focused, there have been scarce attempts to further reduce donor-site complications in the abdomen. Seroma formation is a significant complication after the superficial based abdominal flap harvest. The authors report our novel technique to address this issue. Using indocyanine green (ICG) lymphography, we identified lymphatic leakage sites in the abdominal donor site and repaired them by selective suture: ICG-guided lymphatic vessel suture ligation (ICG-LVSL). We performed ICG-LVSL for 10 patients who underwent breast reconstruction using the superficial abdominal flap and compared the incidence of seroma development between ICG-LVSL and non-LVSL groups. After propensity score matching, nine patients remained in each group. The ICG-LVSL group experienced lower incidence of seroma formation (0 versus 55%, P <0.01). The ICG-LVSL technique may be useful for reducing donor-site morbidity of the superficial abdominal flap., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

This article introduces a reproducible strategy for complex reconstruction scenarios that require the use of two flaps. It specifically focuses on the utilization of the superficial circumflex iliac artery perforator (SCIP) flap as a secondary flap, particularly in complex cases where available arterial options are limited. In the first scenario, the SCIP flap is elevated simultaneously during elevation of a fibula bone flap. The pedicle of the fibula flap will be anastomosed to the recipient vessels, and the pedicle artery of the SCIP flap, the superficial circumflex iliac artery, will be anastomosed to the distal end of the peroneal artery. The SCIP flap pedicle offers greater length compared with a cutaneous flap sourced from the peroneal artery, thus providing increased flexibility for the flap inset. In the second scenario, the SCIP flap is combined with the anterolateral thigh (ALT) flap to manage a significant defect. The pedicle of the ALT flap is anastomosed to the recipient vessels, and the superficial circumflex iliac artery is anastomosed to the distal end of the pedicle artery of the ALT flap, the descending branch of the lateral circumflex femoral artery. The SCIP flap can be harvested simultaneously with a fibula flap or an ALT flap from the same side, and its arterial anastomosis can always be established with the distal ends of the arterial pedicle of these two flaps. This efficient and reproducible method can also contribute to minimal donor site morbidity and will be particularly valuable in settings where recipient artery choices are limited., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Superficial inferior epigastric artery (SIEA) flap is often chosen to minimize postoperative complications such as abdominal pain and bulging. However, drawbacks, including a small diameter and a short pedicle, pose challenges in anastomosing or creating the lower pole of the breast. Here, we report a case of breast reconstruction using an SIEA flap with pedicle elongation via an arteriovenous loop (AV-loop) using a contralateral superficial inferior epigastric vein (SIEV) graft. A 49-year-old woman underwent a left total mastectomy with the primary insertion of a tissue expander. Breast reconstruction using an SIEA flap with pedicle elongation was planned. The running pattern, pedicle length, and diameter of bilateral SIEA/SIEV and superficial circumflex iliac artery and vein (SCIA/SCIV) were evaluated preoperatively using a 48-MHz probe of ultra-high-frequency ultrasonography (Vevo MD ultrasound device, Fujifilm Visual Sonics, Amsterdam, the Netherlands). During the flap harvesting, the contralateral SIEV graft was harvested to create an AV-loop for pedicle elongation. The 9 cm graft was anastomosed to the left internal mammary artery and vein (IMA/IMV). After the flap elevation, the created AV-loop was divided at the midpoint and anastomosed to the pedicle of the SIEA flap. The SIEA flap, extended with a SIEV AV-loop, facilitated the augmentation of the lower pole of the breast without the risk of pedicle kinking and pulling. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. The prolonged pedicle length via an AV-loop prevents the pedicle kinking and allows for positioning the flap more freely, resulting in an aesthetically good breast contour by filling in the lower pole. The precise preoperative evaluation of the vessels using ultra-high-frequency ultrasonography facilitated meticulous planning. In cases where surgeons aim to minimize intraoperative and postoperative complications associated with other abdominal free flaps, this method may be considered a viable and promising option., (© 2024 Wiley Periodicals LLC.)

Summary: Although supermicrosurgery techniques are essential skills for lymphatic surgery or perforator-flap surgery, an ideal training model is yet to be introduced. Living animal models, such as rodents, are considered to be ideal microsurgical training models. However, the use of living animal models is costly and involves bioethical considerations. Hence, the authors developed a novel, cost-effective, highly reproducible, and easy-to-handle supermicrosurgical anastomosis training system using the chicken embryo within the egg-in-cube system. Chick embryos were fertilized in the artificial cubic eggshell, which was fabricated by integrating a polycarbonate frame structure and five polydimethylsiloxane membranes. Seven days later, the trainees underwent supermicrosurgical training using the vitelline artery of the chick embryo. The trainees were able to perform supermicrosurgical training using all 11 surviving chicken embryos. The average diameter of the vitelline artery was 0.43 mm. Patency and pulsation were observed after the anastomosis in four of the 11 cases. The supermicrosurgical training system using the chicken embryo within the egg-in-cube system has several advantages. This system is ethically acceptable, less costly and easier to manage than other animal models, and suitable as a supermicrosurgical training model, such as for lymphovenular anastomosis, because the diameter of the vitelline artery was similar to that of the lymphatic vessels in patients with lymphedema. Moreover, the trainee can confirm patency and leakage after the anastomosis because this model has a circulation system. The trainee can practice the supermicrosurgical technique efficiently with simultaneous feedback on anastomosis results., Clinical Relevance Statement: This study introduces a novel, cost-effective supermicrosurgical training system using chicken embryos within an egg-in-cube, offering a practical and ethical alternative. Its close simulation to human lymphatic vessels supports skill enhancement for practicing surgeons., (Copyright © 2023 by the American Society of Plastic Surgeons.)

The objective of this study was to establish an animal model of arteriosclerosis for assessing vasospasm and to investigate the relationship between arteriosclerosis and vasospasm. Twelve-week-old male Sprague-Dawley rats were fed a diet supplemented with adenine and vitamin D (adenine/vitD). Body weight, blood, and femoral artery histopathology were assessed at 2, 4, and 6 weeks. Change in the femoral artery was examined by transmission electron microscope (TEM). Vasospasm was induced by administering epinephrine extravascularly into the femoral artery and released by the treatment with lidocaine as a vasodilator. During this period, the extravascular diameter and blood flow were measured. The rats in the adenine/vitD group developed renal dysfunction, uremia, hyperphosphatemia, and elevated serum alkaline phosphatase. Histological and TEM analyses of the femoral arteries in the treated rats revealed the degeneration of elastic fibers and extensive calcification of the tunica media and intima. Vascular smooth muscles were degenerated and osteoblasts were developed, resulting in calcified arteriosclerosis. Vasospasm in arteriosclerotic arteries was detected; however, vasodilation as well as an increase in the blood flow was not observed. This study revealed the development of vasospasm in the femoral arteries of the arteriosclerotic rats and, a conventional vasodilator did not release the vasospasm., (© 2023.

Background: Although autologous reconstruction following breast cancer surgery is common, little is known about the association between preoperative body mass index (BMI) and short-term surgical outcomes. This study investigated the association between BMI and short-term surgical outcomes in autologous breast reconstruction using a nationwide Japanese inpatient database., Methods: We retrospectively identified female patients with breast cancer who underwent breast reconstruction using a pedicled flap or free flap from July 2010 to March 2020. Multivariable regression analyses and restricted cubic spline analyses were conducted to investigate the associations between BMI and short-term outcomes with adjustment for demographic and clinical backgrounds., Results: Of the 13,734 eligible patients, 7.1% and 22.2% had a BMI of < 18.5 kg/m 2 and > 25 kg/m 2 , respectively. Compared with BMI of 18.5-21.9 kg/m 2 , overweight (25.0-29.9 kg/m 2 ) and obese (≥ 30.0 kg/m 2 ) were significantly associated with higher occurrences of takebacks (odds ratio, 1.74 [95% confidence interval, 1.28-2.38] and 2.89 [1.88-4.43], respectively) and overall complications (1.37 [1.20-1.57] and 1.77 [1.42-2.20], respectively). In the restricted cubic spline analyses, BMI showed J-shaped associations with takebacks, overall complications, local complications, and wound dehiscence. BMI also demonstrated linear associations with postoperative surgical site infection, duration of anesthesia, duration of drainage, length of stay, and hospitalization costs., Conclusion: In autologous breast reconstruction following breast cancer surgery, a higher BMI was associated with takebacks, morbidity, a longer hospital stay, and higher total costs, whereas a lower BMI was associated with fewer surgical site infections, a shorter hospital stay, and lower total costs., (© 2023.

Background and Objectives : Surgical management of local recurrence of soft tissue sarcomas (STS) is still challenging. In this article, we report on multiple flap reconstructions for multiple local recurrences of STS. Their feasibility will be validated by examining clinical cases. Materials and Methods : Patients who underwent multiple flap reconstructions for multiple local recurrences of STS between April 1997 and October 2021 were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics, and postoperative complications were examined. Results : Twenty operations of eight patients were identified. The location of the defects was the back in two, the buttock in two, the groin in two, and the lower extremities in two. The average total number of wide resections was 4.0 and the average total number of flap reconstructions was 2.5. The average follow-up period was 109.4 months. The average size of the defect was 102.4 cm 2 and the average flap size was 15.7 × 10.8 cm. The histological diagnoses were malignant fibrous histocytoma (MFH) in eight operations, osteosarcoma in two operations, myxoid liposarcoma in two operations, undifferentiated pleomorphic sarcoma (UPS) in six operations, and myxofibrosarcoma (MFS) in one operation. Of twelve subsequent operations, the resection of the previously transferred flap was performed in six operations (50%). The occurrence of take back, flap complications, and donor-site complications in the primary operation group was 25%, 25%, and 12.5%, respectively. The occurrence of take back, flap complications, and donor-site complications in the second and subsequent operation group was 0%, 0%, and 16.7%, respectively. Conclusions : Multiple operations including wide resections followed by flap reconstructions for multiple local recurrences are feasible. Reconstructive surgeons should choose the options of the flaps considering the future local recurrence for tumors with a high risk of recurrence.

Background: Reconstruction after wide resection of a sarcoma arising in the shoulder girdle is challenging, and little evidence is available to compare short-term outcomes between pedicled-flap and free-flap reconstruction., Patients and Methods: Thirty-eight patients undergoing immediate reconstruction surgery with only a pedicled-flap (n = 18) and with a free-flap (n = 20) after sarcoma resection on the shoulder girdle between July 2005 and March 2022 were identified. One-to-one propensity score matching was performed to compare the postoperative complications., Results: Transferred flaps survived completely in 20 cases in the free-flap group. In the all-patient analysis of binary outcomes, the occurrences of total complications, takebacks, total flap complications, and flap dehiscence were higher in the pedicled-flap group than in the free-flap group. The propensity score-matched analysis showed the occurrence of total complications was significantly higher in the pedicled-flap group than the free-flap group (53.8% vs. 7.7%, p = 0.03). In the propensity score-matched analysis of continuous outcomes, the pedicled-flap group demonstrated a shorter operation time than the free-flap group (279 vs. 381 min, p = 0.05)., Conclusions: This clinical study demonstrated the feasibility and reliability of a free-flap transfer for the defect after wide resection of a sarcoma arising in the shoulder girdle., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2023 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background and Objectives: Soft tissue reconstruction after sarcoma ablation in the posterior aspect of the upper arm has been commonly addressed using the pedicled latissimus dorsi musculo-cutaneous flap. The use of a free flap for coverage of this region has not been reported in detail. The goal of this study was to characterize the anatomical configuration of the deep brachial artery in the posterior upper arm and assess its clinical utility as a recipient artery for free-flap transfers. Materials and Methods: In total, 18 upper arms from 9 cadavers were used for anatomical study to identify the deep brachial artery's origin and point of crossing the x -axis, which was set from the acromion to the medial epicondyle of the humerus. Measurements of the diameter were taken at each point. The anatomic findings of the deep brachial artery were employed clinically in the reconstruction of the posterior upper arm after sarcoma resection using free flaps in 6 patients. Results: The deep brachial artery was found in all specimens between the long head and the lateral head of the triceps brachii muscle, and it crossed the x -axis at an average distance of 13.2 ± 2.9 cm from the acromion, with an average diameter of 1.9 ± 0.49 mm. In all 6 clinical cases, the superficial circumflex iliac perforator flap was transferred to cover the defect. The average size of the recipient artery, the deep brachial artery, was 1.8 mm (range, from 1.2 to 2.0 mm). The average diameter of the pedicle artery, the superficial circumflex iliac artery, was 1.5 mm (range, from 1.2 to 1.8 mm). All flaps survived completely with no postoperative complications. Conclusions: The deep brachial artery can be a reliable recipient artery in free-flap transfers for posterior upper arm reconstruction, given its anatomical consistency and sufficient diameter.

In the treatment of sarcoma, the reconstructive surgeon must consider not only limb salvage but also functional reconstruction. The aim of this study was to evaluate a functional reconstruction of a dorsal forearm defect after sarcoma resection using immediate tendon transfer. Patients who underwent reconstruction of a dorsal forearm defect after sarcoma resection with an immediate tendon transfer between 1997 and 2019 at our hospital were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics and functional outcomes were examined. Nine patients were included in this study. Tendon transfer of the flexor carpi radialis (FCR) or the flexor carpi ulnaris (FCU) to the extensor digitorum communis (EDC), the brachioradialis (BR) to the EDC, and the palmaris longus (PL) tendon to the extensor pollicis longus (EPL) was performed in seven, two and five patients, respectively. Seven patients underwent reconstruction using a free flap. Neither anastomosis complications nor infections were encountered. Partial flap necrosis and donor site dehiscence were seen in one case each. The mean distal interphalangeal (DIP), proximal interphalangeal (PIP) and metacarpophalangeal (MP) joint active extension were 4.4°, 6.1° and 11.1° postoperatively. The mean Musculoskeletal Tumor Society (MSTS) score was 26. Immediate tendon transfers of the FCR or the FCU to the EDC and the PL tendon to the EPL can be considered an optimal functional reconstruction of a dorsal forearm defect after sarcoma resection.

Background: Despite the increasing popularity of autologous breast reconstruction, limited evidence is available. The aim of the present study was to compare the short-term outcomes of pedicled- and free-flap breast reconstructions., Methods: Using a nationwide Japanese inpatient database, we identified 13,838 patients who underwent breast reconstruction for breast cancer (July 2010-March 2020) using a pedicled or free-flap (pedicled- and free-flap groups, n = 8279 and 5559, respectively). One-to-one propensity score matching was performed to compare the occurrence of postoperative complications, duration of anesthesia, length of stay, and total costs between the two groups. We also performed subgroup analyses stratified by hospital volume., Results: The propensity score-matched analysis involving 3524 pairs showed that the pedicled-flap group had significantly lower proportions of takeback (2.1% vs. 3.2%, p < 0.001), thrombosis (0.6% vs. 1.7%, p < 0.001), and postoperative bleeding (2.1% vs. 5.7%, p < 0.001) than the free-flap group. No significant differences were found in wound dehiscence or tissue necrosis. Compared to the free-flap group, the pedicled-flap group had a short duration of anesthesia (412 vs. 647 min, p < 0.001) and low total hospitalization costs (12 662 vs. 17 247 US dollars, p < 0.001) but a prolonged postoperative length of stay (13 vs. 12 days, p < 0.001). The subgroup analyses showed results compatible with those of the main analysis., Conclusions: In this large nationwide cohort of patients who underwent breast reconstruction, pedicled-flap reconstruction was associated with fewer postoperative complications (excluding necrosis and wound dehiscence) and lower hospitalization costs but a longer postoperative length of stay than free-flap reconstruction., (© 2022.

Background:  Reconstruction after wide resection of a large sarcoma arising in the posterior trunk may require free-flap transfer to reduce the postoperative complications. Here, we describe the recipient vessels on the whole posterior trunk. Moreover, to show the reliability of these vessels, we describe an institutional series of free-flap reconstruction., Methods:  In the cadaveric study, 20 posterior trunk regions from 10 fixed cadavers were dissected. The location and the diameter of the perforating artery and vein on the posterior were documented. In the clinical study, 54 patients undergoing immediate reconstruction surgery with only a pedicled flap ( n  = 45) and with a free flap ( n  = 9) after sarcoma resection on the posterior trunk between July 2005 and September 2021 were identified. One-to-one propensity score matching was performed to compare the postoperative complications., Results:  In the cadaveric study, a total of 178 perforators were identified. The average diameter of the superficial cervical artery (SCA) and vein, dorsal scapular artery (DSA) and vein, medial branch of dorsal intercostal artery perforator (m-DICAP) and vein, lateral branch of dorsal intercostal artery perforator (l-DICAP) and vein, and dorsolateral intercostal artery perforator (DLICAP) and vein were 1.03, 1.67, 1.38, 1.84, 1.28, 1.84, 1.01, 1.60, 1.11, and 1.70 mm. In the clinical study, the propensity score-matched analysis involving eight pairs showed a significantly higher occurrence of total complications in the pedicled-flap group than the free-flap group (62.5 vs. 0%, p  = 0.03)., Conclusion:  The cadaveric study showed that the perforators from the SCA, DSA, and posterior intercostal artery are constantly present. The clinical study demonstrated the feasibility and reliability of a free-flap transfer., Competing Interests: None declared., (Thieme. All rights reserved.)

Background and Objectives : Prolonged drain stay and lymphorrhea are often problems at the donor site of the superficial circumflex iliac artery perforator (SCIP) flap. This study aimed to introduce a novel technique of the SCIP flap elevation: Deep Fat Saving (DFS) technique. Materials and Methods : Thirty-two patients who underwent the SCIP flap transfer were divided based on the flap-elevated layer: above the deep fascia or the Camper fascia saving the deep fat. The duration of drain stay and the rates of flap survival and donor-site complications were compared between the groups. The inverse probability weighting (IPW) method was conducted to balance confounders. Results : By IPW, two balanced pseudo-populations were created: DFS = 33.9 and Conventional = 31.3. There were no significant differences in the rate of flap survival (DFS: 100% verses Conventional: 95.8%, p = 0.32) and donor site complications (DFS: 2.4% versus Conventional: 1.3%, p = 0.68, respectively). The duration of drain stay was shorter in the DFS group (weighted median: 6 versus 8 days; weighted difference: -1.6 days (95% confidence interval: -2.8 to -0.4), p = 0.01). Conclusions : An SCIP flap can be reliably harvested using the Deep Fat Saving technique.

Background:  Recent advances in the superficial circumflex iliac artery (SCIA) perforator flap transfer emphasized the necessity to comprehensively understand the lower abdominal vasculature. This study aimed to clarify the relationship among the superficial inferior epigastric artery (SIEA), the superficial branch (SCIAs), and the deep branch (SCIAd) of the SCIA., Methods:  Computed tomographic angiography was retrospectively reviewed in 312 hemiabdomens in 161 female patients who underwent abdominal flap breast reconstruction. We assessed the presence, caliber, and branching patterns of the SCIA branches and the SIEA., Results:  The SIEA-SCIA common trunk was present in 40.1% of the hemiabdomen and was identified in either side of the abdomen in 63.6% of patients. At least one superficial vessel larger than 1.5 mm was found in 61.5% of hemiabdomens. Seven branching patterns of the SCIA-SIEA system were noted: (1) the SCIA and the SIEA originated together (17.0%); (2) the SIEA and the SCIAs shared an origin (22.8%), (3) the SCIA and the SIEA branched separately (17.0%), (4) each artery originated separately (8.0%); (5) the SCIAs and the SCIAd emerged together with the SIEA absent (17.3%); (6) the SCIAs and the SCIAd originated separately with the SIEA absent (13.1%); (7) the SIEA and SCIAd originated separately with the SCIAs absent (3.5%)., Conclusion:  SCIA-SIEA branching patterns were classified into seven distinctive patterns. This novel classification may help surgeons to choose the optimal pedicle when using the hemi-abdomen region as the donor site., Competing Interests: None declared., (Thieme. All rights reserved.)

Background: Breast reconstruction using autologous tissue has been widely performed, and its safety and usefulness have been reported. However, there are few reports on the long-term morphological evaluation of autologous breast reconstruction cases. We evaluated long-term change of breast shape using Vectra, a 3-dimensional imaging device, for breast reconstruction cases with more than 10 years of follow-up., Methods: The subjects had undergone autologous tissue breast reconstruction between 2007 and 2009. Sixteen deep inferior epigastric perforator flap cases were included in this study. For each patient, 4 items were measured as indicators: breast width, distance from the sternal notch to the nipple, distance from the nipple to the inframammary fold, and breast volume. The ratio of reconstructed breast to healthy breast was calculated for these 4 items., Results: The long-term average ratio of breast width was 0.99, that of distance from the sternal notch to the nipple was 0.98, that of distance from the nipple to the inframammary fold was 0.94, and that of breast volume was 1.13. We evaluated the influence of body mass index and age at the time of the primary reconstructive surgery, but there was no significant difference in 2 body mass index groups (obese and nonobese groups) and 2 age groups (less than and more than 50 years old)., Conclusion: We assumed that the balance between the reconstructed breast and the contralateral native breast would become worse over time because of breast sagging and changes in breast elasticity. According to our study, the shape balance of left and right breasts was maintained over time. Limitation of this study is the fact that more than half of the cases included in this study had undergone small to moderate revision surgery during the course of follow-up., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background and Objectives : Among many donor site options for autologous breast reconstruction, the use of the profunda femoris artery perforator (PAP) flap has become common in patients who are not suitable for the gold standard procedure, the deep inferior epigastric artery perforator flap. However, its limited volume has precluded its wide use in breast reconstruction. The aim of this report was to demonstrate the effectiveness of a method in which the anatomical position of the pectoralis major muscle was adjusted to augment the volume of the superior pole of the breast during PAP flap transfer. A comparison was made with a conventional PAP flap breast reconstruction. Materials and Methods : Fifty-nine consecutive cases where unilateral autologous breast reconstruction was performed using the vertically designed PAP flap were retrospectively reviewed. Conventional PAP flap transfer was performed in 36 patients (Group 1), and PAP flap transfer with pectoralis major muscle augmentation was performed in 23 patients (Group 2). Results : The patient satisfaction at 12 months postoperatively was statistically greater in Group 2, with the pectoralis major muscle augmentation, than in Group 1 [23/36 (64%) vs. 22/23 (96%), p = 0.005]. There were no significant differences in postoperative complication rates at the reconstructed site [2/36 (5.6%) vs. 0/23 (0%), p = 0.52]. Conclusions : Higher patient satisfaction could be achieved with pectoralis major muscle augmentation in PAP flap breast reconstruction without increasing the postoperative complication rate at the reconstructed site.

Docetaxel-based chemotherapy, which is administered before or after axillary lymph node dissection (ALND) in breast cancer patients with positive axillary lymph nodes, is reported as an independent risk factor for development of breast cancer-related lymphoedema (BCRL). Severe hardening of the soft tissue, which is a typical manifestation of BCRL with a history of docetaxel-based chemotherapy, has been considered a contraindication for lymph-venous anastomosis (LVA). This study aimed to evaluate the efficacy of LVA for BCRL with a history of the use of docetaxel. Twenty-six consecutive BCRL patients who underwent LVA were reviewed retrospectively. All patients underwent ALND. Amongst 23 patients who had chemotherapy for breast cancer, docetaxel-based chemotherapy was administered in 12 patients. The postoperative change of the limb circumferences and the improvement of subjective symptoms were assessed. Overall, patients showed improvements of the limb circumferences at the wrist, the elbow, and 5 cm above and below the elbow. There were no statistical differences of the postoperative changes of the circumferences between the docetaxel-administered and non-administered groups (0.25% vs. 2.8% at 5 cm above the elbow ( p = 0.23), -0.4% vs. 0.7% at 5 cm below the elbow ( p = 0.56), and 2.5% vs. 2.5 % at the wrist ( p = 0.82)). LVA is comparably effective for lymphedematous patients who had undergone docetaxel-based chemotherapy before or after ALND.

Background:  The superficial circumflex iliac artery (SCIA) perforator (SCIP) flap has gained acceptance among reconstructive microsurgeons, the minimal donor site morbidity being its greatest advantage. The purpose of this article is to introduce the use of preoperative ultrasonography to facilitate elevation and to avoid postoperative complications of the SCIP flap., Methods:  Preoperative mapping of the SCIA and the superficial circumflex iliac vein (SCIV) using a high-resolution ultrasound system were performed in patients undergoing reconstruction using a free SCIP flap. The skin paddle was designed placing the SCIA and the SCIV in the middle of the flap., Results:  Preoperatively marked SCIA and SCIV were found intraoperatively in all cases. The skin paddle design for sufficient arterial inflow and venous drainage resulted in no postoperative flap complications., Conclusion:  The use of a preoperative high-resolution ultrasound system significantly facilitates elevation of the SCIP flap, notably via the following 2 points: 1) pedicle can always be found under the markings made with preoperative ultrasonography, 2) satisfactory perfusion of the flap can be guaranteed via a safe flap design that includes preoperatively marked vessels within the skin paddle., Competing Interests: None declared., (Thieme.

The incidence of upper extremity lymphedema after breast cancer treatment is reported to be 14% after axillary lymph node dissection (ALND) and 33% after ALND and regional lymph node dissection. The present report describes a novel method in which the afferent lymphatic vessels are harvested with their lymph nodes from the Zone 4 region as a separate flap, the superficial circumflex iliac artery perforator (SCIP) flap, in the setting of autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap. From September 2017 to September 2020, seven female patients with an average age of 46.9 years (range: 39 to 54 years) underwent autologous breast reconstruction using the DIEP flap and the lymphatic SCIP flap procured separately from the Zone 4 region. All patients had undergone ALND, four patients had undergone radiation therapy, and three patients had established lymphedema at the time of reconstruction. All lymphatic SCIP flaps survived completely. Lymphedema did not occur in any of the four patients to whom the lymphatic flap was transferred for a preventive purpose (average follow-up: 37.5 months). In three patients with established lymphedema at the time of reconstruction, the average rate of estimated volume decrease at the last follow-up (average: 29.0 months) was 12.6%. A lymphatic SCIP flap procured from the Zone 4 region in DIEP flap breast reconstruction can contribute to improvement or prevention of lymphedema with no additional donor site.

Background:  During elevation of the superficial circumflex iliac artery (SCIA) perforator (SCIP) flaps, the flap pedicle must often be converted from the superficial branch to the deep branch of the SCIA, complicating and prolonging the procedure. The goal of the present study was to demonstrate the effectiveness of high-resolution ultrasonography to decrease the conversion rate on which no previous report has focused, by making a comparison with a conventional method., Methods:  Forty-five consecutive cases where free SCIP flap transfer was performed for reconstruction were retrospectively reviewed. To preoperatively mark the course of the superficial branch, handheld Doppler ultrasonography was used in 27 cases (group 1) and a high-resolution ultrasound system in 18 cases (group 2)., Results:  The conversion rate was significantly greater in group 1 than in group 2 (10/27 [37%] vs. 0/18 [0%], p  = 0.003]. The frequency of use of multiple venous anastomoses was significantly higher in group 1 than in group 2 (21/27 [78%] vs. 2/18 [11%], p  < 0.001). The operative time was significantly longer in group 1 than in group 2 ( p  = 0.038). There were no significant differences in postoperative complication rates (1/27 [4%] versus 0/18 [0%], p  = 1.0)., Conclusion:  The use of a preoperative high-resolution ultrasound system significantly decreased the rate from of intraoperative conversion from the superficial branch to the deep branch of the SCIA. It also resulted in significantly fewer venous anastomoses and a shorter operative time, while maintaining a low incidence of postoperative complications., Competing Interests: None declared., (Thieme.

Background: A goal in ideal lower eyelid reconstruction is to achieve not only an esthetic recovery of the shape of the eyelid but also to obtain satisfactory eyelid function without damage to the corneal surface. In this report, we introduce our "Like with Like" reconstruction technique using a combined Hughes flap and swing skin flap. The Hughes flap is a tarsoconjunctival pedicled flap from the upper eyelid, and the swing skin flap is a kind of transposition flap based on the orbicularis muscle pedicle., Patients and Methods: Eight patients who had more than 25% of the lower eyelid affected by a full-thickness defect were included. There were five men and three women, and the average age was 68.4years old. All patients had undergone wide tumor excision of the lower eyelid due to a malignant tumor and had also had primary two-stage eyelid reconstruction with a combined Hughes flap and swing skin flap., Results: The average reconstructive time was 1:20, and no postoperative severe complications such as flap necrosis or wound dehiscence were observed. The follow-up period was an average of one year, and there were no functional problems such as ectropion, lower eyelid retraction, lid margin hypertrophy, lacrimation disorder, or corneal problems observed in any cases. Esthetically, no reconstructed eyelid bulging or asymmetry in the lid margin was observed in any of the cases., Conclusions: Combining the Hughes flap and skin swing flap technique might be the best choice for a full-thickness lower eyelid defect with regard to the esthetic and functional results., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Aplasia Cutis Congenita (ACC) in the scalp is a rare congenital malformation. The treatment for ACC with large defects involving the scalp, bone, and the dura is challenging. Local debridement of necrotic tissue is important to prevent lethal complications such as infection and meningitis. However, debridement has the risk of damaging the sagittal sinus or the dura. Recent developments in ultra-high-frequency ultrasound(US) systems provide frequencies of 70 MHz and capability resolution as fine as 30 μm, which could allow precise imaging of small and thin anatomical structures. The study aimed to describe the methods of precise evaluation of the defect in the scalp and safe debridement using ultra-high-frequency US. This is the first report on direct observation of a newborn's brain using ultra-high-frequency US. The boy was delivered spontaneously with a large defect of the scalp and bone. After 14 days, due to signs of infection, local debridement was performed carefully under ultra-high-frequency US-based evaluation. The dura, the sagittal sinus, and the small anatomical structures such as arachnoid granulations could be observed. Because the brain herniation gradually aggravated, dural reconstruction using fascia lata and scalp reconstruction using transposition flap was performed. Finally, good skin coverage over the defects was obtained. This method minimizes the risk of damaging the sagittal sinus and the brain parenchyma, which may cause fatal complications. Although further clinical investigations will be required to confirm its efficacy, ultra-high-frequency US has the potential to be a useful device for ACC treatment., Competing Interests: Disclosure: The authors have no financial interest in relation to the content of this article., (Copyright © 2021 The Authors.

Background: The use of intraoperative indocyanine green (ICG) angiography has been well documented for confirmation of arterial perfusion in transferred free flaps. However, no previous report has yet focused on whether ICG angiography can be used to detect congestion in free flaps. The present report investigates the feasibility of ICG angiography for detecting flap congestion intraoperatively through illustrative cases., Methods: From September 2019 to September 2020, 65 consecutive female patients who underwent breast reconstructions using a free deep inferior epigastric perforator (DIEP) flap were enrolled in this study. Forty-eight patients with 52 DIEP flaps were eligible for the study after application of the exclusion criteria. ICG angiography was performed after elevation of the flap, after completion of the anastomoses, and after inset of the flap., Results: In five cases (9.6%), an inadequate highlight was demonstrated with ICG angiography performed after flap elevation. All such cases were deemed congestive since robust bleeding was observed with the prick test. ICG angiography demonstrated sufficient highlight of the flap after removal of the clamp on the superficial inferior epigastric vein. In two cases (4.2%), kinking of the pedicle vein of the DIEP flap was found with ICG angiography performed after inset of the flap. In both cases, the pedicle and the flap were reinset. All flaps survived completely postoperatively., Conclusion: ICG angiography can detect flap congestion, and the proposed 3-step protocol is useful for the prevention of postoperative complications., (© 2021 Wiley Periodicals LLC.)

Background: Autologous repair using costal cartilage grafts remains the most widely accepted method of microtia reconstruction. A major complication of current techniques is loss of ear shape caused by scarring, contracture and cartilage absorption. We present a new surgical technique utilizing the posterior auricular artery free flap in microsurgical reconstruction of the retroauricular sulcus in microtia., Method: Reconstruction is performed in two stages. In the first stage, a fabricated costal cartilage framework is inserted into a skin pocket as described by Nagata. In the second stage, the ear framework is elevated from the scalp and held by an additional cartilage wedge. Following indocyanine green angiography perforator mapping, a posterior auricular artery perforator flap is harvested from the contralateral (normal) ear and used to reconstruct the posterior auricular sulcus covering the cartilage framework and elevating wedge., Results: The technique was applied to three patients aged 11-15 years with a follow-up time of 8 months to 3 years. The average flap artery diameter was 0.73 mm and the vein was 0.7 mm. Venous congestion occurred in one case and was resolved with a vein graft leading to complete flap recovery. Good ear shape, elevation, projection, skin color and texture were achieved in all the cases., Conclusion: Posterior auricular artery flap reconstruction of the retroauricular sulcus in microtia repair is a useful alternative to the current skin graft and tissue expander-based techniques. It provides the ideal skin color and texture match and may improve the overall results of microtia reconstruction by enhancing vascularity., Competing Interests: Declaration of Competing Interest The authors declare that there is no conflict of interest., (Copyright © 2021 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Lymphaticovenular anastomosis (LVA) is a challenging procedure and requires a sophisticated supermicrosurgical technique. The aim of this study was to evaluate and establish a discrete supermicrosurgical anastomosis method using the "suture-stent technique"., Methods: Forty-eight LVA sites of twenty patients with lower extremity lymphedema who had undergone LVA between July 2020 and January 2021 were included in this study. LVA was performed with the conventional technique or with the suture-stent technique. The patency of the anastomoses was evaluated using an infrared camera system intraoperatively. The success rate on the first try and the final success rate for each group were compared., Results: After full application of the exclusion criteria, 35 LVAs of 16 patients including 20 limbs were included in the analysis. The ratio of good patency findings after anastomosis in the suture-stent technique group was 100%. The incidences of leakage or occlusion on the first try were statistically greater in the conventional technique group (29.4%) than in the suture-stent technique group (0%) ( p = 0.0191). All anastomoses achieved good patency in the final results., Conclusion: With its minimal risk of catching the back wall during the anastomosis, the suture-stent technique can be considered an optimal anastomosis option for LVA.

Background: Recently, the deep inferior epigastric perforator (DIEP) flap has become the gold standard for breast reconstruction, but it has some drawbacks such as abdominal bulging and hernia. To overcome these disadvantages, the superficial inferior epigastric artery perforator (SIEA) flap is used as an alternative option, but it has another problem, namely limited vascular territory and risk of vascular thrombosis. To solve these problems, we introduced our new technique, a combined SIEA and superficial circumflex iliac artery perforator (SCIP) based double pedicled abdominal flap. In this report, we present our experience of using this technique., Methods: The SIEA and SCIP based double pedicled abdominal flap was used in five patients who wanted to have unilateral breast reconstruction after a mastectomy due to breast cancer. The average age was 48.2 (range 38-56) years, and the average BMI was 24.4 (range 19.2-31.4). The SIEA and SCIP based double pedicled abdominal flap was designed as a modified DIEP flap, and all flaps were placed in the vertical setting. The flap pedicles had two different vascular supplies, SIEA and SCIA, and the drainage systems, SIEV and SCIV, anastomosed to the internal mammary artery and vein in all cases., Results: The harvested SIEA and SCIP based double pedicled abdominal flaps were a median volume of 925 g (range 452-1570 g) and average size of 491 cm 2 (range 440-611 cm 2 ). The average reconstructive time was 7:41 (range 6:31-9:17). In four out of the five cases, the SIEA and SCIA joined together to make a common pedicle artery trunk, and its average size was 1.08 mm. Four out of the five cases had a wide vascular territory crossing the abdominal midline as shown by ICG angiography. One case showed ICG fluorescence for the hemi-side of the abdominal flap. Postoperative course was uneventful, and there were no major perioperative complications, which need extra surgical procedures. Follow-up period averaged 273 days (range 194-312 days)., Conclusion: The SIEA and SCIP based double pedicled abdominal flap showed viable flap territory across the midline in all cases. The SIEA and SCIP based double pedicled abdominal flap might be another ideal option for breast reconstruction, when appropriate SIEA and SCIA pedicles are identified, and an adequate ICG fluorescence is obtained for the size of flap needed., (© 2021 Wiley Periodicals LLC.)

Background: Postoperative complications after flap-coverage in sarcoma treatment can postpone postoperative adjunct treatments. Here, we present our experience with the use of the superficial circumflex iliac artery perforator (SCIP) flap after sarcoma resection., Patients and Methods: Patients undergoing immediate reconstruction surgery with a flap after sarcoma resection at a single institution from February 2017 to April 2020 were identified. Patient demographics, tumor characteristics, surgical characteristics, and complications were examined., Results: Thirty-five consecutive patients underwent reconstructions using a SCIP flap (34 free and one pedicled SCIP flaps). We also identified 47 consecutive patients who underwent reconstruction with other pedicled or free flaps over the same time period. No significant differences were found in patient age, gender, defect size, or operative time between these two groups. The incidences of overall complications (20/47 [42.6%] vs. 3/35 [8.5%], p < .001), flap dehiscence (7/47 [14.8%] vs. 0/35 [0%], p = .018), and total flap complications (15/47 [31.9%] vs. 2/35 [5.7%], p = .005) were statistically greater in the control group than in the SCIP group., Conclusion: With its minimal postoperative complication rate both in the reconstruction site and the donor site, the SCIP flap can be considered an optimal reconstruction option after sarcoma resection., (© 2021 Wiley Periodicals LLC.)

Background: In the setting of the reconstruction for a large defect, we must make the maximum use of the limited human tissue with the minimum damage. In this article, we report on reconstruction using a combination of three-skin paddle latissimus dorsi and a scapular flap for a large defect after soft tissue sarcoma resection to minimize donor site morbidity., Methods: From 2000 to 2012, six patients underwent primary reconstruction using free or pedicled triple-lobe combined latissimus dorsi and scapular flap after wide resection of soft tissue sarcoma. There were five male patient and one female, and their average age was 66.8 (range, 49-80 years). The location of the defects was the thoracic wall in three, the thigh in one, the knee in one, and the shoulder in one. The average size of the defect was 18.8 × 13.9 cm., Results: The average size of the ascending scapular flap and the skin paddle of the latissimus dorsi flap was 6.8 × 13 cm and 7.3 × 14.7 cm. One patient had partial necrosis of the skin paddle of the latissimus dorsi flap, which was treated conservatively. The triple-lobe combined latissimus dorsi and scapular flaps survived completely in five cases. Neither anastomosis complications nor infections were encountered. The average follow-up period was 63.67 months. All patients were satisfied functionally and esthetically with the reconstruction outcomes at the end of follow-up., Conclusion: In conclusion, the triple-lobe combined latissimus dorsi and scapular flap is one of the options for reconstruction of a large defect after sarcoma resection to minimize donor site morbidity., (© 2020 Wiley Periodicals LLC.)

Soft tissue sarcomas are rare neoplasms that can occur on any part of the body. The operative position for the resection is determined depending on the site of the soft tissue sarcomas; intraoperative repositioning may be needed for reconstruction. We present the profunda femoris artery perforator (PAP) flap harvest technique (wherein the flap can be used in any position), and suggest that the PAP flap transfer can eliminate the need for intraoperative repositioning., Methods: From December 2018 to January 2020, 7 patients with an average age of 68 years underwent reconstructions using a PAP flap after wide resection of STS. The mean defect size was 11.3 × 16.5 cm (range, 5.5-25 × 11-26 cm). The location of the defects was the medial thigh in 2 patients, the posterior thigh in 1, the popliteal fossa in 1, the groin in 1, and the buttock in 2. The PAP flap was elevated in the supine "frog-leg" position, the prone position, the jack-knife position, or the lateral "crisscross" position; the lateral decubitus position with the donor lower extremity on the bottom., Results: Of the 7 cases, the operations were performed in the supine "frog-leg" position in 3 cases, the prone position in 2 cases, the jack-knife position in 1 case, and the lateral "crisscross" position in 1 case. There were no intraoperative position changes in all cases. The mean size of the PAP flap was 8.7 × 19.9 cm (range, 6-11 × 17-24 cm). One patient had donor site dehiscence, which was treated conservatively. The PAP flaps survived completely in all cases. The mean follow-up period was 10.5 months (range, 6-17 months)., Conclusion: Since the PAP flap elevation is feasible in every position, the PAP flap can be considered a versatile reconstruction option after sarcoma resection., (Copyright © 2020 The Authors.

The profunda artery perforator (PAP) flap has become an alternative option for breast reconstruction. Reliable perforators arise through the adductor magnus muscle, and dissection of the perforator is straightforward. Recently, we have found that the PAP flap with the sensory nerves can be harvested as an innervated flap. We discuss the feasibility of PAP flap neurotization. We reviewed 13 patients for whom innervated PAP flap harvesting was considered. The average age was 50.7 years. There are 3 different patterns of innervated PAP flap harvesting, Type 1: including a sensory nerve that can be found in the adipose tissue around the PAP flap, Type 2: including a sensory nerve that runs along the medial femoral circumflex system, and Type 3: including a sensory nerve that runs along the profunda artery perforators. The average flap harvest time was 2:11 ± 0:31, and a sensory nerve was identified in 10 of 13 cases (77%). No sensory nerves were found in the other 3 cases. The length of the included sensory nerve was 5.5 ± 1.6 mm on average. Types 1 and 2 were found in 3 patients (30%), Type 3 was found in 2 patients (20%), and combined Types 1 and 3, 2 and 3 were found in one patient each (10%). As sensory nerves run around the PAP flap or close to the perforators, it is easy to perform flap neurotization with the PAP flap. We believe that the PAP flap could be an alternative option to achieve sensate breast reconstruction., Competing Interests: Disclosure: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2020 The Authors.

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 cm 2 (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., (© 2020 Wiley Periodicals, Inc.)

Background and Objectives: The profunda femoris artery perforator (PAP) flap is gaining popularity in microsurgical reconstruction. The complications that can occur after the PAP flap harvest include donor-site lymphedema, seroma, or cellulitis. The aim of this study was to evaluate and establish a safer technique for the elevation of lymphatic vessels preserving profunda femoris artery perforator (LpPAP) flap using pre- and intraoperative ICG lymphography. In this article, we also evaluate the anatomical relationship between the PAP flap and lymph-collecting vessels., Methods: From July of 2018 to January of 2019, 24 patients with soft tissue defects after tumor resection underwent reconstruction using PAP flaps. The lymph-collecting vessels at the medial thigh area were identified using pre- and intraoperative ICG lymphography. A PAP flap was elevated taking care not to damage lymph-collecting vessels. After flap elevation, the anatomical correlation between lymph-collecting vessels and the anterior edge of the gracilis muscle was measured. The postoperative complications were assessed., Results: PAP flaps survived completely in all cases. In all cases, using intraoperative ICG lymphography, surgeons confirmed that the lymph-collecting vessels in the medial thigh region were left intact. There were no donor site complications such as lymphedema, lymphorrhea, or cellulitis., Conclusion: The elevation technique of an LpPAP flap is effective in reducing the risk of damage to lymph-collecting vessels, and thus reducing chances of postoperative lymphorrhea or iatrogenic lower limb lymphedema., (Copyright © 2020.

Thanks to the introduction of virtual surgical planning (VSP), mandibular reconstruction using a fibula flap has become simplified, and patient-specific reconstruction is now possible. With a VSP software, surgical "cutting guides" and custom-made titanium plates can be designed to help surgeons. However, they are expensive and require extended periods of time either for prototyping or to acquire the advanced knowledge necessary for operating the VSP software. The aim of this article is to introduce a new easy and low-cost method of surgical planning for mandible reconstruction using a computer-aided design and the syringe-aided manufacturing technique. Simulations of fibula osteotomy are performed using regular and commercially available 10-ml syringes. The syringes are cut into separate segments to fit the defect of the 3-dimensional mandible model and to match the prebent titanium plate. The syringe segments are then connected together 3-dimensionally to confirm that the shape matched both the contour of the defect and the angles of the mandible. The simulated syringe segments are used as cutting guides. Then osteotomies are performed according to the cutting guide to obtain the exact lengths and angles required to achieve precise bony reconstruction. The mandibular reconstruction procedures are successful, with a good match between the preoperative planned syringe models and the final results of the surgery. Although further clinical investigation will be required to confirm its efficacy, the computer-aided design and the syringe-aided manufacturing method has the potential to be a useful technique for mandible reconstruction using a vascularized fibula flap., Competing Interests: Disclosure: The authors have no financial interest to declare in relation to the content of this article, (Copyright © 2020 The Authors.
