RESUMO

Autologous breast reconstructions have grown in popularity because of their durability, aesthetic outcomes, symmetry, increase in external beam radiotherapy use, and potential aesthetic enhancement at the donor site. Increasing patient expectations for predictable high aesthetic outcomes with minimal complications or need for further procedures has been met by refinement in the use of flaps. The authors' microsurgical breast reconstruction center aims to provide this while delivering efficient service. The deep inferior epigastric flaps form 85% and transverse upper gracilis and profunda artery perforator flaps account for 10%; lumbar artery perforator flaps are a new addition to the authors' armamentarium.

RESUMO

LEARNING OBJECTIVES: After reviewing this article, the participant should be able to: 1. List major risk factors for hernia formation and for failure of primary repair. 2. Outline an algorithmic approach to anterior abdominal wall reconstruction based on the degree of contamination, components involved in the deficit, and width of the hernia defect. 3. Describe appropriate indications for synthetic and biological mesh products. 4. List common flaps used in anterior abdominal wall reconstruction, including functional restoration strategies. 5. Describe the current state of the art of vascularized composite tissue allotransplantation strategies for abdominal wall reconstruction. SUMMARY: Plastic surgeons have an increasingly important role in abdominal wall reconstruction-from recalcitrant, large incisional hernias to complete loss of abdominal wall domain. A review of current algorithms is warranted to match evolving surgical techniques and a growing number of available implant materials. The purpose of this article is to provide an updated review of treatment strategies to provide an approach to the full spectrum of abdominal wall deficits encountered in the modern plastic surgery practice.

RESUMO

Selecting potential recipient vessel options for free flap anastomosis is an important consideration in microsurgical breast and chest wall reconstruction. In these settings, the most common comprise the internal mammary and thoracodorsal vessels, although alternative anastomotic sites have also been described. On occasion, consideration of these alternatives becomes a necessity. The use of five separate recipient vessels is highlighted in a unique case of recurrent locally advanced breast cancer requiring multiple complex reconstructions using free tissue transfer. A 56-year-old lady presented for delayed breast reconstruction one year after radical mastectomy for locally advanced lobular breast cancer. Despite wide resections, local chest-wall recurrence five times necessitated five microsurgical reconstructions, using separate recipient pedicles: internal mammary vessels, thoracodorsal vessels, serratus branch of thoracodorsal vessels, intercostal vessels and thoracoacromial vessels. All flaps survived completely, without donor or recipient complications. There has not been a subsequent recurrence at 6 months since last reconstruction. The purpose of this report is to present the first reported case of microsurgical chest wall reconstruction using five separate free flaps requiring anastomosis to multiple recipient vessels for anterior chest wall coverage, to present a literature-based and clinical review of the regional vascular anatomy of the anterior chest wall, and to present an operative approach algorithm. In such complex cases, this understanding can facilitate a streamlined approach to management. © 2014 Wiley Periodicals, Inc. Microsurgery 37:66-70, 2017.

RESUMO

BACKGROUND: An increasing number of women undergo mastectomy for breast cancer and post-mastectomy autologous breast reconstruction has been shown to significantly improve the psychosexual wellbeing of the patients. A goal of treatment is to achieve symmetry and projection to match the native breast, and/or the contralateral breast in the case of a unilateral reconstruction. Autologous reconstruction, particularly with the deep inferior epigastric artery perforator (DIEP) flap, is particularly advantageous as it can be manipulated to mimic the shape and turgor of the native breast. However, very few techniques of shaping the breast conus when insetting the DIEP flap to enhance aesthetic outcome have been reported to date. With the aide of three-dimension (3D) photography and 3D-printed mirrored image of the contralateral breast as a guide intraoperatively, we describe our St Andrew's coning technique to create a personalized flap projection. METHOD: We report a prospective case series of 3 delayed unilateral breast reconstructions where symmetrization procedure to the contralateral breast was not indicated. Using a commercial 3D scanner (VECTRA XR, Canfield Scientific), the breast region was imaged. The mirrored image was 3D-printed in-house using a desktop 3D printer. RESULTS: In all cases, projection of the breast mound was able to be safely achieved, with a demonstrated central volume (or 'cone') able to be highlighted on imaging and a 3D printed breast. A 3D print of the contralateral breast was able to be used intraoperatively to guide the operative approach. CONCLUSIONS: The St Andrew's coning technique is a useful aesthetic maneuver for achieving breast projection during DIEP flap breast reconstruction, with 3D imaging techniques able to assist in perioperative assessment of breast volume.

RESUMO

BACKGROUND: Venous couplers are ubiquitous around the world and are a useful tool for the reconstructive microsurgeon. A systematic review of coupler performance studies demonstrated a thrombosis rate range of 0% to 3%, whilst the average time of using the device is 5 minutes. There is sparse published data on cost analysis and the impact of operator experience on the anastomotic coupler device success. Improvements in outcomes other than time benefits have also not been shown. This study aims to address these deficiencies in the literature. METHODS: A retrospective clinical study was undertaken, aiming to compare equivalent groups of patients that had free flap surgery with venous micro-anastomoses with those that had sutured anastomoses. The cohort comprised all patients undergoing microsurgical breast reconstruction at the St Andrew's Centre for Plastic Surgery & Burns from January 2009 to December 2014. RESULTS: Between January 2010 to December 2014, 1,064 patients underwent 1,206 free flap breast reconstructions. The average age of patients was 50 years. Seventy percent of patients underwent mastectomy and immediate reconstruction during this period with the remaining 30% having a delayed reconstruction. The 1,206 free flaps comprised of 83 transverse myocutaneous gracilis (TMG) flaps, and 1,123 deep inferior epigastric artery perforator (DIEP) flaps. In total the coupler was used in 319 flaps, 26% of the cohort. There was a statistically significant clinical benefit in using the anastomotic coupler for venous anastomosis. Overall, the return to theatre rate was 12.69% whilst the overall flap loss rate was 0.75%. The overall coupler failure rate was significantly less at 1.4% whilst sutured vein failure rate was 3.57% (P=0.001). CONCLUSIONS: The anastomotic coupler for venous anastomosis in free flap surgery is associated with reduced operating times, reduced take-backs to theatre and cost benefits. This is the first study to demonstrate clear clinical benefits to anastomotic couplers, and suggests that these may be the gold standard for venous microanastomosis. With increasing experience with their use and technological advances, these outcomes may continue to improve.

RESUMO

BACKGROUND: Breast reconstruction is a multi-stage process, involving many individual procedures and many healthcare professionals which take the patient through from diagnosis of breast cancer to the completion of cancer treatment and ultimate breast reconstruction. With an experience of over 3,000 autologous breast reconstructions, we have refined both our surgical technique and overall approach to breast reconstruction to improve the efficiency in free flap based breast reconstruction surgery. METHODS: Through a process mapping approach similar to that employed by large-scale industry, we have broken down free flap based breast reconstruction into multiple smaller processes. By looking at various steps as a simple component of the whole, we have improved our theatre efficiency to maximize patient throughput and improve our outcomes for breast reconstruction patients. RESULTS: Since beginning free flap breast reconstruction surgery, we have improved overall efficiency by applying a process mapping approach. In our early experience, we undertook a single patient undergoing breast reconstruction with a free flap per theatre list, moving to two patients having breast reconstruction, and now carry out three free flap based reconstructions in a single theatre per day as a routine. Specific times are demonstrated, with no increased complication rate. CONCLUSIONS: Through clearly defined processes, operative efficiency in autologous breast reconstruction can achieve three free flaps per day in a single theatre.

RESUMO

BACKGROUND: Stacked and bipedicled abdominal flaps are useful in women who require a large breast reconstruction but have relative paucity of abdominal tissue. A new classification system is described to assist the surgeon in achieving the best possible aesthetic outcome. METHODS: A retrospective review of 25 consecutive stacked and/or bipedicled deep inferior epigastric perforator (DIEP) flap reconstructions was assessed from 2009 to 2014. Demographic data and key variables were prospectively collected in our breast reconstruction database and an aesthetic classification devised. There are four main subtypes, (I) folded; (II) divided; (III) coned; and (IV) divided and folded. Each of these subtypes can be moulded in a symmetrically or asymmetrically fashion depending on the contralateral breast shape together with distribution and consistency of fat within the abdominal flap. RESULTS: Of the 25 patients, three-quarter were immediate reconstruction, with an average age of 48 years and a median follow-up of 2 years 10 months. Just over half the patients (57%) had bipedicle flaps with two recipient donor vessels with the remaining 43% had stacked flaps. The most common recipient sites are the thoracodorsal vessels (62%) and intercostal perforators (26%). The average abdominal pannus weight was 610 grams (SD: 320 grams), with a hemi-abdominal weight of 305 grams. Two patients had haematomas, of which one lost their reconstruction. Another patient had a venous congestion flap which was salvaged. CONCLUSIONS: Bipedicled or stacked abdominal flaps allow the all four zones of the abdominal tissue to be used in unilateral breast reconstruction. The approach of tailoring the abdominal flaps to match the contralateral breast reconstruction is largely an art form. The paper aims to bring some meaningful system to aid the surgeon to achieve the best possible outcome with the components presented to them.

RESUMO

BACKGROUND: Advances in mobile telecommunication, improved mobile internet and affordability have led to a significant increase in smartphone use within medicine. The capability of instant messaging, photography, videography, word processing, drawing and internet access allow significant potential in this small portable device. Smartphone use within medicine has grown tremendously worldwide given its affordability, improved internet and capabilities. METHODS: We have searched for apps specifically helpful in the perioperative care of microsurgical breast reconstructive patients. RESULTS: The useful apps have been subdivided: (I) communication apps-multimedia messaging, WhatsApp, PicSafeMedi: allow efficient communication via text, picture and video messages leading to earlier assessment and definitive management of free flaps; (II) storage apps-Notability, Elogbook: electronic storage of patient notes and logbooks of case which can be shared with others if required; (III) educational apps-FlapApp, Touch Surgery, PubMed on tap: step by step guides to surgical procedures to aid learning and medical journal database; (IV) flap monitoring app-SilpaRamanitor: free flap monitoring app based on photographic analysis for earlier detection of compromised flaps. CONCLUSIONS: There has been remarkable growth in smartphones use among surgeons. Apps are being developed for every conceivable use. The future will be in wearable smart devices that allow continuous monitoring with the potential to instigate change should deviations from the norm occur. The smart watch is the start of this digital revolution.

RESUMO

For autologous breast reconstruction, there are cases where one free flap cannot provide the volume of tissue required, and the concept of 'stacked' bilateral deep inferior epigastric artery (DIEP) flaps was developed, in which hemi-abdominal flaps are raised on each deep inferior epigastric artery (DIEA), and both flaps transferred to the chest. In cases of bilateral breast reconstruction, stacked flaps may be required to achieve volume replacement, however options are not described. We demonstrate the use of stacked free flaps for bilateral breast reconstruction, using one DIEP flap stacked with one transverse upper gracilis (TUG) flap for each side. A 49-year-old woman, with BRCA1 mutation, presented for risk reduction mastectomies. Flap design was planned to achieve maximal projection and primary nipple reconstruction. This was able to be achieved by using the DIEP flap de-epithelialised and completely buried, with the flap orientated with the pedicle on its superficial surface, and the TUG flap lying superficially with its skin paddle used for nipple reconstruction and able to be monitored clinically. There were no flap or donor related complications and good aesthetic outcomes were achieved. This technique offers a further option in microsurgical breast reconstruction for patients in whom there is a paucity of abdominal tissue for reconstruction.
