Background: Intraoperative thrombosis during microvascular surgery is a nasty complication. Most intraoperative thromboses occur at the proximity of the anastomosis and microsurgical salvage techniques are needed to correct the complication. The aim of this article is to provide an overview of basic clinical patency testing and microsurgical salvage techniques. Methods: A search of the literature up to November 2020 was performed, using PubMed and Web of Science databases. Articles reporting on clinical intraoperative patency testing and/or salvage techniques in microvascular surgery were included. Results: Comprehensive illustrations of intraoperative clinical patency testing include: pulsation pattern, flicker test and milking test. The following surgical salvage techniques for both end-to-end and end-to-side intraoperative microvascular occlusion management are described: suture-line thrombectomy, thrombectomy through arteriotomy, anastomotic resection with complete re-anastomosis and, balloon extraction. Conclusion: Decision making in surgical salvage techniques for microvascular thrombosis depends on localization of the thrombus and the surgeon’s experience and preference. In case of any doubt, it is better to reopen a few sutures and have a clear inspection of the anastomosis in order to prevent redo surgeries. This paper serves as a guide for especially the starting microsurgeon to clinically and surgically identify and handle an intraoperative microvascular anastomosis thrombosis and occlusion.

Extravasation is the movement of fluid outside its conduit into the extracellular tissue, possibly leading to a local inflammatory reaction, compartment syndrome, tissue necrosis, and full thickness skin loss at the affected area. To prevent these complications, early recognition, referral and treatment of an extravasation injury is of utter importance.We present a case, illustrating an extravasation injury into the breast managed by a renovated surgical technique - emergency evacuation low-pressure suction (EELS). A 54-year-old woman attended the emergency department with 1.5 L of total parenteral nutrition leaked into her right breast via a central portal catheter. The patient was seen within 24 hours of the incident, and presented with a diffuse swollen, tender and erythematous right breast but no overlying skin necrosis. Dry EELS via two small stab incisions was performed to evacuate the extravasated total parenteral nutrition and to minimise the aspiration of healthy fat tissue of the breast. Only a few cases of extravasation injuries into the breast have been described and most cases involve chemotherapy extravasation from a central catheter. Presumably there is an underreporting of this complication in the literature.This case-report promotes the use of aspiration in the management of diffusely spread extravasated injuries. EELS is a more appropriate term than liposuction, as there is no intention to evacuate healthy fat tissue. This new term is less confusing and might help medical staff and patients to better understand the treatment as it will break the affiliation with an aesthetic procedure. It is an effective and cosmetically satisfactory technique to treat early total parenteral nutrition extravasation injury at the level of the breast.

Objective: Breast reconstructions with perforator flaps from the lower abdomen, commonly known as Deep Inferior Epigastric artery Perforator flap (DIEP-flap), have become the golden standard for autologous breast reconstruction after breast amputation. During this surgical procedure multiple challenging steps are encountered such as the selection of a suitable perforator that provides sufficient blood supply for the flap, surgical dissection of the chosen perforator, determination of perfusion area of the chosen perforator, microsurgical anastomosis, flap inset and shaping the flap into a breast. The current gold standard for perforator mapping is Computed Tomography Angiography (CTA). However, this is a relatively expensive imaging modality that requires intravenous contrast injection and exposes patients to ionizing radiation. More recently, Dynamic Infrared Thermography (DIRT) has been proposed as an alternative imaging modality for perforator identification. DIRT appears to be an ideal alternative technique not only for the identification of the dominant perforators, but also for the mapping of the individual influence of each perforator on the flap perfusion, to monitor integrity of the perforator after dissection and to monitor the patency of the pedicle of the free flap after the anastomosis, during flap inset and flap shaping. Study design: In this clinical study we present the results of the use of DIRT in 33 DIEP-flaps in 21 patients after mastectomy. The same standardized measurement set-up was used for all the flaps in the pre-, intraand postoperative period. Results: In the pre-operative period DIRT confirmed the location of the 69 perforators shown on the CTA. In the intra-operative period the rate and pattern of rewarming was successfully observed. One perforator was severely damaged during dissection and the DIEP flap was converted to a Muscle Sparing free Transverse Rectus Abdominis Muscle (TRAM) flap, after viability check of the flap by DIRT. DIRT diagnosed one kinking of the pedicle after microsurgical anastomosis. Two flaps were monitored successfully postoperatively. All 33 breast reconstructions were with good outcome. Conclusion: The use of DIRTwith our standardized measurement setup is a useful, non-invasive tool during breast reconstructions with free DIEP-flaps in all the phases of the reconstruction (pre-, intraand post-operative). This study confirms that DIRT with the standardized measurement setup provides information on perforator location, blood supply and patency of the anastomosis without interference with the operating surgeon.

Introduction Perineal bowel evisceration is a rare complication after extralevator abdominoperineal excision (ELAPE). This surgical technique is used to resect low rectal and anal cancer, with a lower likelihood of positive surgical margins, but resulting in a larger perineal defect. A vertical rectus abdominis myocutaneous (VRAM) flap allows filling of the empty pelvic space and closure of the defect in the pelvic floor. Case presentation A 77-year-old woman, with a hysterectomy in her medical history, underwent an ELAPE followed by reconstruction of the perineal defect with a VRAM flap after neoadjuvant radiotherapy for a moderately differentiated invasive adenocarcinoma of the distal rectum. The postoperative course was complicated with a herniation of the perineal wound and evisceration of a bowel loop. Conclusion Closure of the perineal defect after ELAPE remains a challenge, especially in cases where several risk factors for delayed wound healing, flap failure and perineal herniation are present.

Dynamic infrared thermography (DIRT) has been used to locate perforating vessels and to assist in reconstructive breast surgery. Qualitative information on the perforating vessels is obtained by analyzing the rate and pattern of rewarming of hot spots which are easily registered with an infrared camera. Thermal measurements are made before and during surgery and are compared with the CT images available before the operation. The thermal images can provide the individual influence of each perforator on the flap, as well as the dimensions of the perfused area. It will be investigated if the thermal image sequence locating the different dominant perforators will prove to be a useful tool for reconstructive DIEP-flap surgery

Infrared thermography technology has improved dramatically in recent years and is gaining renewed interest in medicine for applications such as skin tissue identification, breast reconstruction using DIEP flaps, psoriasis etc. However, there is still a need for an optimized measurement setup and protocol to acquire the most appropriate images for decision-making and further processing. Nowadays, different cooling methods are used, but a general optimized cooling protocol has not been defined yet. In this manuscript, a standardized cooling technique and measurement setup, are reviewed and optimized. It is possible to improve the thermal images by choosing an appropriate cooling method, cooling, and optimized measurement setup

BACKGROUND: Large and ptotic breasts are considered an anatomical contraindication for nipple sparing mastectomy (NSM). Necrosis rates can be as high as 76%. The authors examined whether targeted preshaping mastopexy/reduction combined with simultaneous two-stage preshaping of the implant pocket prepares for an uneventful implant reconstruction. METHODS: Macromastia and ptosis patients opting for risk-reducing NSM or having a peripherally localized carcinoma in situ, were offered a two-stage mastopexy/reduction simultaneously with preshaping of the implant pocket by subpectoral expansion. Only the inferior pedicle bearing the nipple-areola complex (NAC), remained. A delayed secondary NSM and tissue expander-to-implant reconstruction was scheduled 3 months later. The use of an acellular dermal matrix (ADM) was not necessary because the capsule around the expander created a hammock supporting the definite prosthesis. Follow up was at 2 weeks, 3 months, and 6 months. RESULTS: Forty-one procedures were performed in 24 patients. The mean age was 45±12.08 years (range, 22 to 72 years). Patients’ mean body mass index (BMI) was 26.79 kg/m(2) (range, 19 to 35 kg/m(2)). One patient had diabetes and two smoked. One transient epidermolysis of the NAC occurred in each stage. No NAC or skin necrosis occurred; no implant had to be removed. CONCLUSIONS: A two-stage mastopexy/reduction, simultaneously with preshaping of the implant pocket by tissue expansion and followed by a 3-month delayed secondary NSM with tissue expander-to-implant reconstruction is a safe technique in large ptotic breasts.

Infrared thermography technology has improved drastically in recent years and is regaining interest in medicine for applications such as deep inferior epigastric perforate flap breast reconstruction, breast cancer diagnosis, skin tissue identification, psoriasis detection, etc. However, there is still a need for an optimised measurement setup and protocol in order to capture the most suitable images for decision making and further processing. Nowadays, different cooling methods are being used; nevertheless, a general optimised cooling protocol is not yet defined. In this manuscript, several cooling techniques, as well as the measurement setups, are reviewed and optimised. It is possible to enhance the thermal images by selecting an appropriate cooling method and duration, and additionally, an optimised measurement setup enables a comparison between different inspections.

Background Vaccination against COVID-19 has started in several countries already and is on its way in others. However, there is an important hesitance towards the vaccine. The aim of this study is to evaluate the vaccination hesitance and main concerns towards the vaccine among surgeons. Methods An anonymous survey of 16 questions was sent to 138 Belgian surgeons before the start of vaccination in Belgium. The questions were divided into sections, evaluating demographics, COVID-19 test status and symptoms, the surgeon's opinion on the COVID-19 vaccination and their main concerns. Results Ninety-three out of 138 surgeons (67.4%) completed the survey: two-third of them were residents. Sixty-nine surgeons (74.2%) do want to get vaccinated. Forty-two surgeons (45.2%) feel like they do not have enough information about the vaccine. Residents feel significantly more underinformed than consultants (52.3% and 29.0%, respectively). Surgeons who feel to be well-informed are more willing to get vaccinated (92.2%) compared to those who feel to have a lack of information (52.4%). The main concerns among surgeons include effectiveness (26.9%), safety and side effects (19.4%) and organisation and vaccination strategy (12.9%). Twenty-five surgeons (26.9%) have no concerns at all. Conclusion Most surgeons (74.2%) are ready for their COVID-19 vaccine. However, some of the surgeons are still doubtful about the vaccine. A lack of information plays a major role in their scepticism. A strong communication strategy is necessary to educate, reassure and motivate surgeons to get vaccinated.

Background: Elastofibroma dorsi (ED) is a benign slow growing soft tissue tumor that is most frequently located subscapular. The prevalence is estimated to be 2% on imaging studies in individuals over 60 years old and might occur bilaterally. The etiology, however, remains unclear. Case presentation: This report presents the case of a man with bilateral ED. He first presented at the age of 49 with a subscapular ED on the right side and again at the age of 53 with a subscapular ED on the left side. At both times, diagnosis of ED was histopathologically confirmed after surgical resection. And, again at both times, the postoperative course was characterized by seroma development. Discussion: This report shows a brief review of literature on ED. It contains a summary of the current data on prevalence, etiology, clinical presentation, diagnosis, histopathological findings, surgical treatment and postoperative management. It also includes a flowchart for diagnostic and therapeutic approach. Conclusions: ED might present bilaterally, though not necessarily affecting both sides simultaneously. In order to diagnose ED MRI is ought to be sufficient. Invasive procedures, i.e. complete surgical excision, are mandatory to treat symptomatic ED, although such surgical procedures are often complicated by seroma formation.

Eccrine porocarcinoma is a rare and potentially fatal malignant adnexal tumor that can arise de novo or develop from its benign precursor, poroma. Diagnosis is difficult due to its rarity and resemblance to many other (benign) skin tumors. We present the case of a 71-year-old woman presenting with a long-standing case of eccrine porocarcinoma on the scalp. After multiple incomplete excisions over the last 15 years, no metastases were found. Major reconstructive surgery was necessary after complete excision of the lesion. Complete removal of the eccrine porocarcinoma was achieved in 2 stages. The defect was closed with a large rotation flap of the scalp. No adjuvant radio- or chemotherapy was given. Twenty-one months later, the patient presented with a rapidly growing lymph node recurrence, which was treated by lymph node dissection followed by chemoradiation. This case demonstrates the consequences of suboptimal surgical treatments and follow-up of eccrine porocarcinoma and its benign precursor, poroma. Early recognition, proper pathological diagnosis, and adequate surgical treatment are highly recommended in order to obtain a good prognostic outcome. Level of evidence: Level V, Risk/Prognostic study.

Background:Autologous fat grafting [AFG] is a surgical technique used to correct breast deformities or to reconstruct partial breast deformities after breast conservative treatment [BCT] or mastectomy for breast cancer. However, a strong debate remains upon the topic of safety and the oncological risk after lipofilling. There is a need for more studies assigned with a higher level of evidence. Objective:This retrospective cohort study aimed to provide a strong evidence-based argument concerning the safety of fat grafting in patients who underwent breast cancer surgery in comparison to a group with similar characteristics who did not receive lipofilling. Methods: Two cohorts consisting of women with a history of breast cancer were retrospectively assembled. All patients underwent BCT and/or a mastectomy as breast cancer treatment. An intervention population of patients that had received primary or secondary lipofilling was statistically compared to a control population of patients that had received a breast reconstruction without lipofilling. Results: Fifty patients with a mean age of 53.6 ± 9.3 years at the time of lipofilling were included in the intervention cohort. The control group included 67 patients with a mean age of 52.8 ± 8.5 years at the time of breast reconstruction. Both cohorts showed no significant differences for demographic or oncological data. Mean follow-up time was 15.0 ± 15.6 months in the intervention group and 45.4 ± 35.1 months in the control group. The prevalence of the complications are shown in the table. No complications were seen in 35 patients [70%] after lipofilling. Fat necrosis was mostly observed [n=15] but no infections or local oncological recurrences were reported. In the control group a complication-free follow-up occurred in 38 patients [56.7%] after breast reconstruction. One control patient demonstrated a local oncological recurrence. A higher prevalence of infections was observed in the control population [p = 0.048] and the prevalence of fat necrosis was higher after lipofilling [p = 0.028].

We present a 30-year-old man with a sternal Ewing's sarcoma, who was treated by complex resection of the sternal body and reconstruction by a methyl methacrylate sandwich graft and a pedicled latissimus dorsi flap.

In the modern world, one-third or more of breast cancer patients still undergo uni- or bilateral mastectomy. Breast cancer patients, in general, have a good prognosis and long-term survival. Therefore, the treatment must not only focus on survival but also on the quality of life. Breast reconstruction with an autologous free deep inferior epigastric artery perforator (DIEP) flap is one of the preferred options after mastectomy. A challenging step in this procedure is the selection of a suitable perforator that provides sufficient blood supply for the flap to prevent necrosis after anastomosis. In this pilot study, the possibilities for dynamic infrared thermography (DIRT) are investigated to select the best suitable perforator. The measurements are done with external cooling in the preoperative stage to accurately predict the location of the dominant perforators. During the surgery, in the peroperative stage, measurements are done for mapping the influence of a specific perforator on the perfused areas of the abdominal flap. Perforators are sequentially dosed and opened again to map the influence of that perforator on the vascularization of the flap, visualized with the help of the thermographic camera. The acquired steady-state thermal images could help decide which parts of the abdominal flap to use for the reconstruction so that the chance of (partial) necrosis is reduced. In the postoperative stage, DIRT could visualize the arterial and or venous thrombosis before they become clinically obvious as (partial) necrosis. At present DIRT seems to be a valuable investigation for the pre-, per-, and postoperative phases of DIEP-flap reconstructions. Large, high-quality clinical studies are needed to determine its definitive role. (C) 2020 Optical Society of America

Breast reconstruction with an autologous free Deep Inferior Epigastric Perforator (DIEP) flap is one of the preferred options following mastectomy. A challenging step in this procedure is the selection of a suitable perforator that provides sufficient blood supply for the flap. The current golden standard for perforator mapping is computed tomography angiography (CTA). However, this is a relatively expensive imaging modality that requires intravenous contrast injection and exposes patients to ionizing radiation. More recently, dynamic infrared thermography (DIRT) has been proposed as an alternative imaging modality for perforator identification. DIRT appears to be an ideal alternative technique not only for the identification of the dominant perforators, but also for the mapping of the individual influence of each perforator on the flap perfusion. Multiple studies have been performed with the use of DIRT, unfortunately without standardisation of the measurement set-up. In this technical note we propose a standardised and reproducible measurement set-up for the use of DIRT during breast reconstructions with a free DIEP flap. This set-up can be used pre-, intra- and postoperatively. A standardised measurement set-up will improve the quality of measured data and ensure reproducibility.

Background: Ewing's sarcoma is the second most common primary malignant bone tumour in children. Depending on localisation and extent, massive bone defects remain when curative surgery is performed. Whereas in the past, limb amputation was often unavoidable to obtain curative resection, nowadays different limb saving reconstructive options are available. Case report: We report the successful reconstruction of a massive femur defect with a free vascularised fibular graft (FVFG) after Ewing's sarcoma resection in a four-year-old girl. Both the age of the patient and the extensive graft hypertrophy makes this case exceptional. Conclusion: Femur reconstruction with a FVFG is a rarely performed and complex procedure in young children. It is an excellent reconstructive technique for large long bone defects, which can avoid limb amputation without compromising oncologic outcome.

Conservative breast surgery followed by irradiation, often referred to as Breast conserving therapy (BCT), has replaced modified radical mastectomy for the treatment of early stage invasive breast cancer and ductal carcinoma in situ (DCIS). About 10% to 40% of the patients treated with BCT have poor cosmetic outcome results. Small tumours in large breasts can be successfully treated by lumpectomy and radiotherapy, with good cosmetic outcome. However when the tumour breast ratio is higher, the cosmetic outcome can be very disappointing. A surgical conflict arises between optimal oncologic resection and the desire to spare as much tissue as possible to minimize the risk of deformities. In case of a small defect lipofilling can be performed. This technique transplants fat grafts from a donor site to the defect in the breast. In case of larger defects there is the option of oncoplastic surgery. Oncoplastic techniques combine the optimal oncological resection with an adequate reconstruction for optimal cosmetic outcome. Oncoplastic techniques allow the breast surgeon to perform a tumour resection with adequate margins and the plastic surgeon will reconstruct the defect during the same procedure for optimal cosmetic outcome. The use of oncoplastic techniques to reconstruct defects of partial mastectomies (BCT) can be immediate, delayed or immediate delayed. Current breast cancer treatment leads to long-term surivival. It it there for important not only to survive but also life. Therefore the quality of life and good cosmetic outcome is mandatory after breast cancer treatment. Oncoplastic surgery is based on two techniques: volume displacement and volume replacement. The volume displacement techniques use (dermo)glandular flaps of the breast to fill the resection defect. Volume displacement techniques ideally work when the tumour resection can be incorporated in a breast reduction pattern. A similar technique is used on the contralateral breast to match size and shape. The volume replacement techniques use autologous non-breast tissues to compensate the volume loss after tumour resection. Volume replacement techniques are used when a large resection volume is needed in a small breast. Depending on the location and size of the defect many different flaps can be used for partial breast reconstruction. (C) 2018 Elsevier B.V. All rights reserved.

Summary Background Surgeons remain reluctant to perform nipple-sparing mastectomy (NSM) in large breasts due to a higher risk of necrosis. We performed a systematic review of the literature to evaluate indications, techniques, and outcomes in immediate or delayed breast reconstructions in large and/or ptotic breasts. Methods The following search terms were used for both titles and key words: [NSM AND (“breast ptosis” OR “ptotic breast” OR “large breast” OR “breast hypertrophy” OR “gigantomastia”)]. All forms of breast reconstruction in large and/or ptotic breasts from 1990 through September 1st 2018 reporting indications, techniques, and outcomes were included. Results Thirty-one studies met the inclusion criteria, yielding 1128 NSMs (709 immediate and 419 delayed) in 629 patients for analysis. The overall complication rate was 29.08%. The mastectomy flap necrosis rate was 12%, the partial nipple-areola complex (NAC) necrosis 11%, and the complete NAC rate 11%. The overall complication rate in one-stage versus delayed reconstructions was 37.52% versus 14.8%. The incidence of necrosis in one-stage versus delayed reconstructions was 5.36% versus 2.15% for partial, 5.08% versus 0.48% for complete NAC necrosis, and 4.8% versus 1.43% for skin flap necrosis. Conclusions The majority of studies being small and retrospective as well as the large variation in outcomes indicates that we lack consensus on the timing of reconstruction or ideal technique. A noticeable difference in skin flap and NAC necrosis, however, is seen in the favor of NAC-delayed procedures. Randomized controlled trials are mandatory to prove this difference significantly.

A rectovaginal fistula (RVF) is a rare disease. It’s an epithelium-lined abnormal communication between rectum and vagina. It represents approximately 5% of all anorectal fistulas. RVF may have different causes. We present a case of a 58-year-old woman with a rectovaginal fistula after stapled hemorrhoidopexy (Longo operation). A 58-year-old woman presented herself in our department with vaginal fecal discharge and vaginitis almost one month after a stapled hemorrhoidopexy was performed in another hospital. On vaginal examination, a large dorsal defect was palpated at four cm. On rectal examination, the stapler line was palpable at four cm and just distal to this stapler line, a large defect could be palpated. A lower gastrointestinal tract radiography was performed and identified a RVF. The patient was put on antibiotics and two operations were planned. First, a temporary ileostomy was created. After healing of the vaginitis, reconstructive surgery with anatomic fistula repair in combination with the interposition of healthy, vascularised tissue was performed. In this case, we chose the Martius flap. The operation as well as the postoperative course was uneventful. Cases of postoperative RVF have been increasingly reported since the introduction of stapled hemorrhoidopexy. Patients with RVF can have a varying degree of symptoms. Diagnosis is primarily based on the patient’s medical history together with a clinical examination. There are many surgical approaches for RVF. Anatomic fistula repair alone is associated with lower success rates compared with combined procedures with the adjunctive interposition of healthy, vascularised tissue.

In order to identify the exact location of a useful perforator for DIEP flap breast reconstruction, CT images are made in the pre-operative phase. The aim of this research is to evaluate if dynamic infrared thermography is a helpful tool to check and visualize the blood flow in the flap during the pre- and peroperative phase. The results will be used in order to pinpoint the usefulness of IR thermography as an alternative method for perforator mapping and flapdesign. By means of infrared thermography the blood vessel distribution and its vascularisation of the abdominal wall will be visualized. The thermal images can help to detect the correct perforator and can help to decide which parts of the flap are best perfused and can be used for the DIEP flap reconstruction.

Dynamic infrared thermography (DIRT) has been used to locate perforating vessels and to assist in reconstructive breast surgery. Qualitative information on the perforating vessels is obtained by analysing the rate and pattern of rewarming of hot spots which are easily registered with an infrared camera. Thermal measurements are made before and during surgery and are compared with the CT-images available before operation. The thermal images can provide the individual influence of each perforator on the flap, as well as the dimensions of the perfused area. We will investigate if the influence of the different dominant perforators can be assessed by dynamic infrared thermography as a useful tool for recostructive DIEP-flap surgery.

Introduction: Ectopic meningiomas are rare tumors which can be encountered by all surgical specialties. Patients and methods: We report on two different cases, a contemporary one and a historical one, highlighting the diversity of clinical presentations and prognoses of these lesions. Furthermore epidemiological aspects, clinical features, and diagnostic and therapeutic work-up in patients with an ectopic meningioma are reviewed. Results: Typically, ectopic meningiomas present as gradually expanding lesions, causing a variety of symptoms by their mass effect. Diagnosis is based on histological characteristics, which are similar to those of intracranial meningiomas. Treatment is primarily surgical. Conclusions: The cases we report are at different ends of the clinical and prognostic spectrum. Therapeutic options for different clinical scenarios are discussed.

Objective: Subcutaneous emphysema can be an alarming sign of a necrotizing soft tissue infection. However, non-infectious etiologies exist that can be treated conservatively. This case report describes a subcutaneous emphysema of unknown origin and highlights the importance of distinguishing these clinical entities. Methods: We present a 17-year old female with pain and subcutaneous emphysema of the left arm. There were no systemic symptoms. Inflammatory parameters were slightly elevated. Computed tomography (CT) scan of the chest excluded intrathoracic abnormalities. Despite antibiotic treatment, the pain increased and the emphysema extended. Necrotizing fasciitis was feared. A surgical exploration was performed and hyperbaric oxygen therapy was started. Results: Intraoperatively, puncture marks were identified on the left arm. Air noticeably escaped, but normal, unaffected tissues were identified and microbiological cultures remained negative. We observed a good clinical evolution. Conclusion: The lack of apparent causes, the unexplained puncture marks and psychiatric comorbidity suggests the possibility of subcutaneous emphysema due to factitious manipulations. Patients with subcutaneous emphysema who remain clinically stable, have minimal pain and no significant inflammatory changes could be treated conservatively. Close clinical monitoring is essential to avoid delayed intervention in case of a necrotizing soft tissue infection.

Reconstructive surgery aims to improve quality of life by recreating a natural-looking breast that is warm to the touch. To obtain symmetry and body contour alignment, restoration of volume within the skin envelope is mandatory. The chosen reconstruction technique depends on the characteristics of the diseased breast, the shape and volume of the contralateral breast, and the technical skills of the surgical team. Timing, type and different possibilities of breast reconstruction are discussed. (C) 2018 Elsevier B.V. All rights reserved.

Summary Background Musculocutaneous flaps have become the first choice in the surgical repair of pressure sores, but the indication for including muscle in the transferred flaps still remains poorly defined. This study compares outcomes after muscle and non-muscle flap coverage of pressure sores to investigate whether it is still necessary to incorporate muscle tissue as part of the surgical treatment of these ulcers. Methods A retrospective revision of 94 consecutive patients with ischial or sacral pressure sores operated between 1996 and 2002 was performed. Depending on the inclusion of muscle into the flap, the patients were divided in two groups: musculocutaneous flap group and fasciocutaneous flap group. Charts were reviewed for patient characteristics, ulcer features and reconstructive information. Data between groups were compared with emphasis on early (haematoma or seroma, dehiscence, infections, necrosis and secondary procedures) and late (recurrence) postoperative complications. Results A total of 37 wounds were covered with muscle and 57 wounds covered without muscle tissue. The groups were comparable in relation to age, gender, ulcer characteristics and timing for surgery. There were no significant differences in early complications between the study groups. The mean follow-up period was 3.10±1.8 years (range: 0.5 to 6.7). There were no statistical differences in ulcer recurrence between the groups. The type of flap used was not associated with postoperative morbidity or recurrence in the univariate and multivariate analyses. Conclusions The findings of this clinical study indicate that the musculocutaneous flaps are as good as fasciocutaneous flaps in the reconstruction of pressure sores, and they question the long-standing dogma that muscle is needed in the repair of these ulcers.

Summary Background Salvage breast reconstruction is defined as a complete revision of a previous reconstruction in case of unsatisfactory results or failure of primary or secondary breast reconstruction. We have termed this ‘tertiary breast reconstruction'. This article presents our experience with tertiary reconstructions, including the indications, method of reconstruction and outcomes. Methods A retrospective note review was performed for all patients who underwent breast reconstruction with autologous tissue under one surgeon between 2002 and 2009 at the University Hospital, Ghent. Out of these 688 patients, 54 patients (7.8%) required tertiary surgery with autologous tissue after failure of implant breast reconstruction. Results The first reconstructive surgery involved 38 unilateral and 16 bilateral cases with a total of 70 operated breasts. A further 11 breasts were reconstructed following risk-reducing mastectomy or at the patient's request for aesthetic reasons. Out of 81 free-flap reconstructions, the deep inferior epigastric artery perforator (DIEAP) flap was the most harvested at 66 (81%). The mean±SD operating time was 7.2±1.8h and the mean hospital stay was 7.2±1.9 days. One total flap loss (1.2%) occurred. The mean follow-up was 31 months with a range between 3 months and 6 years. During follow-up, 30 patients (55.5%) needed secondary procedures to improve the aesthetic outcome. Donor-site corrections were performed in 18 patients (33%). Revisions of the breast flap were performed in 29 patients (53%). Conclusions Restoring the breast envelope and footprint, in addition to excision of scar tissue, is the key step in breast reconstruction. Further corrections are required depending on the amount of the initial damage to the breast or subsequent postoperative complications.

Background: Salvage of a faded autologous breast reconstruction is a complex and challenging problem. The purpose of this study was to analyze the indications, methods. and outcomes of tertiary surgery in patients with a failed autologous breast reconstruction. Methods: A retrospective Chart review was performed for all patients who underwent breast reconstruction with autologous tissue performed by the senior author (M.H.) between 2002 and 2009. Special emphasis was made to evaluate the first reconstruction performed, causes of failure, indications for tertiary reconstruction, and Outcomes. A preoperative hematologic workout was performed. For patients who were classified within the highest group of thromboembolism, specific prophylactic measurements were taken for the tertiary surgery. Results: Of 688 patients who underwent autologous breast reconstruction, a total of 14 patients required tertiary breast reconstruction. Hypercoagulability was found in three patients resulting from disorders such as lupus anticoagulant positivity and antiphospholipid syndrome. Six patients (43 percent) underwent a combination of local skin flaps and/or implant. reconstructions Eight patients (57 percent) underwent nine microvascular breast reconstructions: five superior gluteal artery perforator flaps, three transverse myocutaneous gracilis flaps, and one deep inferior epigastric artery perforator flap. Two of nine flaps (22 percent) required quaternary reconstnictions because ()fa failure of the second free flap. Additional corrections such as revision lipofilling, scar revision, contralateral breast shaping, implant change, and capsulotomies were performed in 92.7 percent of the patients, with a mean follow-up of 37 months (range, 6 months to 7 years). Conclusions: Tertiary surgery after autologous breast reconstruction failure has limited options and further reoperations are often needed. Careful patient history and selective blood tests may reveal hidden coagulation disorders. When a second free flap is planned, primary and secondary antihrombotic therapy should be considered.

Multisutural synostosis may result in frontofacial hypoplasia. The aesthetic and function problems arising from this can be corrected by frontofacial advancement, either by monobloc or bipartition osteotomy. Significantly larger, safer advancements can be achieved using distraction osteogenesis when compared to conventional osteotomy. However, the stability of this technique has been questioned. A retrospective study of 21 patients with craniofacial dysostosis who underwent frontofacial advancement osteotomies using the rigid external distractor system was undertaken. Twelve were distracted on protocol 1 (24 hours after surgery at 1.5 mm/d). Nine were distracted on protocol 2 (7 days after surgery at 1 mm/d). A 6-week consolidation period was used. Changes in frontofacial advancement in the sagittal plane were measured preoperatively, immediately, at 6 months, and where possible thereafter annually using lateral cephalograms and three-dimensional computed tomography scans. The midface was distracted an average of 16.4 mm with a range of 12 to 22 mm as measured in the sagittal plain. Relapse was seen only in 3 of 21 patients, and all of these patients were distracted using protocol 1. Distraction osteogenesis of the frontofacial skeleton using the rigid external distractor frame is generally stable. In this series, a longer latency period and reduced distraction rate resulted in greater stability. Overdistraction in the growing infant is recommended to allow for completion of growth. Overdistraction is not needed to compensate for potential relapse.

The relatively high number of complications and disadvantages of the conventional techniques in breast reduction combined with our expertise in restoring sensation in breast reconstructive procedures, led to the development of a new technique that was crystallised from the traditional techniques and is able to overcome most of their disadvantages. The key issue of the technique is that the nipple is vascularised and innervated on a column of glandular tissue that remains in contact in its posterior part with the pectoralis muscle and its perforators and in its lateral aspect to the lateral pillar of breast tissue. Due to the ptosis that develops during the process of hypertrophy, this column will gain sufficient length to be turned upwards into the new position of the nipple. Resection of glandular tissue is performed cranially, medial and inferior to this column. Undermining of the skin is reduced to an absolute minimum and glandular resections are always performed in the shape of a wedge. In this way, undermining of the breast gland over the pectoralis muscle is avoided. The glandular pedicles are sutured together after loosely fitting the glandular cone with the nipple into its new position. The long term results of the first 68 cases were reviewed and compared to our experience with the superior dermal pedicle technique combined with the vertical scar as described by Lassus and later by Lejour. Due to increased vascularisation of the nipple-areolar complex (NAC), wound complications were markedly reduced with the new technique. Sensation in the NAC was preserved in almost all cases. There was a high satisfaction about the obtained aesthetical results in regard to shape and volume. Increased viability of the NAC, a reduced rate of wound complications and preservation of sensation in NAC are the main advantages of this technique. Additionally, flattening of the NAC is avoided by the support by glandular tissue behind the NAC that improves projection and hereby the aesthetic conic appearance of both breast and nipple.
