Flying high?-Exploring the effect of red bull on blood pressure after microsurgical breast reconstruction in a randomized controlled trial.

BACKGROUND: A sufficiently high blood pressure (BP) is essential for flap perfusion after microsurgical breast reconstruction. However, postoperative hypotension is common after these procedures. Perioperative volume overload may increase flap-related complications, and postoperative vasopressor use may be limited depending on institutions. Red Bull has been shown to increase BP in several studies. We aimed to evaluate the effect of Red Bull on perfusion-related variables after microsurgical breast reconstruction. METHODS: We conducted a multicenter, prospective, randomized controlled trial. Female patients undergoing unilateral microsurgical breast reconstruction from June 2020 to October 2022 were randomly assigned to the intervention or control groups. The intervention group received 250 ml of Red Bull 2 h after surgery and twice on postoperative day (POD) 1. The control group received 250 ml still water at the respective intervals. BP was measured using a 24-hour monitoring device. Vasopressor use, fluid balance, and flap outcomes were compared. RESULTS: One hundred patients were included in the study. Both groups were comparable concerning age, body mass index, and caffeine consumption. Mean arterial and diastolic BP were significantly higher in the Red Bull group after the second drink in the morning of POD1 (p-value = 0.03 and 0.03, respectively). Vasopressor use was similar, with a tendency for less postoperative etilefrine in the Red Bull group (p-value = 0.08). No flap loss was observed. CONCLUSIONS: We observed increased mean arterial and diastolic BP in the Red Bull group after the second drink. Red Bull may be a useful adjunct after microsurgical breast reconstruction. LEVEL OF EVIDENCE: I, therapeutic.

Effect of the Red Bull Energy Drink on Perfusion-Related Variables in Women Undergoing Microsurgical Breast Reconstruction: Protocol and Analysis Plan for a Prospective, Multicenter Randomized Controlled Trial.

BACKGROUND: Maintaining a sufficiently high systolic blood pressure is essential for free flap perfusion after microsurgical breast reconstruction. Yet, many women undergoing these procedures have low postoperative systolic blood pressure. Intravenous volume administration or vasopressors may be needed to maintain systolic blood pressure above a predefined threshold. However, excessive volume administration may lead to volume overload and flap stasis, and the postoperative use of vasopressors may be limited depending on institutional standards. Additional nonpharmacological measures to raise blood pressure might be beneficial. Evidence suggests that the Red Bull energy drink could raise blood pressure. It has been shown to increase systolic and diastolic blood pressure in healthy volunteers and athletes. OBJECTIVE: The primary objective of this study is to determine the difference in systolic blood pressure between an intervention group receiving Red Bull and a control group receiving still water after microsurgical breast reconstruction. Secondary objectives include postoperative heart rate, 24-hour fluid balance, pain level, or necessity for revision surgery due to flap complications. METHODS: The Red Bull study is a prospective, multicenter randomized controlled trial comparing the effect of postoperative ingestion of Red Bull energy drink against still water in female patients undergoing unilateral microsurgical breast reconstruction. A total of 250 mL of Red Bull (intervention group) or 250 mL of still water (control group) will be administered to the study participants 2 hours postoperatively as well as for breakfast and lunch on postoperative day 1, amounting to a total volume of 750 mL per 24 hours. Female patients between 18 and 70 years of age undergoing unilateral microsurgical breast reconstruction will be included. Exclusion criteria are a history of arterial hypertension, cardiac rhythm disorder, diabetes mellitus, gastric or duodenal ulcer, thyroid disease, and current use of antihypertensive or antiarrhythmic drugs or thyroid hormones, as well as intolerance to Red Bull. RESULTS: Recruitment for the study started in June 2020 and was completed in December 2022. There is evidence that the Red Bull energy drink increases blood pressure in healthy volunteers and athletes. We hypothesize that postoperative ingestion of Red Bull will increase systolic blood pressure in women after microsurgical breast reconstruction. Red Bull could hence be used as a nonpharmacological adjunct to vasopressors or volume administration in women with hypotensive blood pressure after microsurgical breast reconstruction. CONCLUSIONS: This paper describes the Red Bull study trial protocol and analysis plan. The information will increase the transparency of the data analysis for the Red Bull study.

Breast implant reverse surgery: A step-by-step approach.

The popularity of breast augmentation has seen a decrease in number in the recent years. Simultaneously, the request for breast implant removal has increased impressively. A total of 77 women undergoing breast implant removal with no exchange were divided into four groups depending on the type of "reverse surgery" following the explantation: simple implant removal, implant removal with lipofilling, implant removal with mastopexy, and implant removal with mastopexy and lipofilling. Following this, an algorithm was created to standardize the ideal "reverse" surgery. After surgery, all the patients were followed for at least 6 months to understand their level of satisfaction regarding the outcome of the surgery. The majority of patients were highly satisfied after explantation. Implant-related issues were found to be the main cause for explantation surgery. Capsulectomy was performed in the minority of cases, as the capsule was found to be an ideal layer for fat grafting. Grouping the patients into 4 categories allowed us to investigate a pattern behind the decision to undergo a certain type of secondary procedure and to create an algorithm with general rules that can be used as a guide for surgeons. The increased demand for this type of surgery underlines a new interesting trend in plastic surgery that, together with Breast Implant-Associated Anaplastic Large Cell Lymphoma advent, will probably have implications on the communication between surgeons and patients and most likely on the choice of choosing different ways of breast volume augmentation.

Trends and Innovations in Autologous Breast Reconstruction.

More than 40 years have passed since the description of the first "free abdominoplasty flap" for breast reconstruction by Holmström. In the meantime, surgical advances and technological innovations have resulted in the widespread adoption of autologous breast reconstruction to recreate the female breast after mastectomy. While concepts and techniques are continuing to evolve, maintaining an overview is challenging. This article provides a review of current trends and recent innovations in autologous breast reconstruction.

Use of free flaps in aesthetic breast surgery: a single centre experience and literature review.

BACKGROUND: Implant-based breast augmentation is one of the most performed procedures in aesthetic surgery, whereas autologous tissue application is confined to fat grafting as adjuvant procedure. The use of free flaps in cosmetic mammoplasties is not popular, but the number of reports in the literature is increasing. We believe that autologous tissue transfer for cosmetic purposes could be a valuable alternative for volume enhancement in selected conditions, especially following weight loss. In this paper, we provide a systematic literature review of the current literature of using autologous free flaps for breast augmentation in non-cancer patients, and we also report our experience on this topic to identify possible indications and criteria for the patients' selection. METHODS: PRISMA's guidelines have been followed for the literature review. In order to demonstrate the feasibility, safety and patient satisfaction with breast volume enhancement with autologous tissue, a retrospective single-centre study was conducted on women who underwent breast volume enhancement with autologous tissue. Patient's satisfaction was assessed with a visual analogue scale (VAS) creating an ad-hoc outcome scale, and the data were summarised with a descriptive statistic. RESULTS: Twelve patients were enrolled in the study. Weight loss was the main indication for surgery. The average length of procedure was 5.1 h, and the hospitalization was 2.3 days. After 12 month, the patient outcome was excellent in 2 cases, good in 9 cases and moderate in 1 case. CONCLUSIONS: Although further research is needed, the literature review and our case series show that the use of free flaps for breast volume enhancement is safe and gives a satisfactory outcome.

Comparing complications and perioperative teams in microsurgical breast reconstruction: retrospective cohort study.

Background: Subspecialization with dedicated perioperative teams has become common practice in some surgical disciplines. While surgeon experience, the number of surgeons involved, and enhanced recovery after surgery (ERAS) pathways are known factors affecting the outcome after microsurgical breast reconstruction, the impact of the perioperative team has not been studied. Methods: We conducted a retrospective cohort study consisting of a chart review of all patients who underwent microsurgical breast reconstruction from January 2019-April 2020. Surgery was performed by three microsurgeons at two institutions with different perioperative teams-one being a small clinic [private clinic (PC), 33 beds] and the other being a larger hospital [corporate hospital (CH), 335 beds]. Patients were grouped into two cohorts according to the institution where surgery was performed. The primary outcomes studied were frequency of revision surgery, flap loss and patient length-of-stay (LOS). Results: One hundred and fifty microsurgical breast reconstructions were performed in 125 patients. Demographic data [age, body mass index (BMI), current tobacco use, donor site] was found statistically comparable between both cohorts. In the PC cohort with fewer perioperative care providers, lower rates of revision surgery and flap loss were observed (P value =0.009 and 0.04, respectively). LOS was not significantly different between the two cohorts (P value =0.44). Conclusions: The outcome of microsurgical breast reconstruction depends on multiple factors. In this study, fewer flap complications occurred at the small clinic. One reason among others might be the lower number of perioperative care providers involved and hence higher likelihood of sharing microsurgical cases, which facilitates routine and ensures less variability in care. The value of perioperative team subspecialization in microsurgical breast reconstruction needs to be assessed in prospective studies.

Microsurgical Breast Reconstruction in Patients with Disorders of Hemostasis: Perioperative Risks and Management.

BACKGROUND: Surgical and technological advances have resulted in the widespread adoption of microsurgical breast reconstruction. Many comorbidities that potentially might impair vasculature and wound healing are no longer considered contraindications for these procedures. However, some uncertainty still prevails regarding the perioperative management of patients with disorders of hemostasis. METHODS: The authors combined a literature review with a retrospective chart review of patients with disorders of hemostasis who had undergone microsurgical breast reconstruction at the senior author's (J.F.) center between 2015 to 2020. Several disorders associated with thrombotic and/or hemorrhagic complications were identified, and a standardized risk assessment and management strategy was developed in cooperation with a hematologist. RESULTS: Overall, 10 studies were identified comprising 29 patients who had a defined disorder of hemostasis and underwent microsurgical breast reconstruction. Seventeen microsurgical breast reconstructions were performed on 11 patients at the senior author's (J.F.) center. High factor VIII levels, heterozygous factor V Leiden, and heterozygous prothrombin mutation G20210A were the most common genetic or mixed genetic/acquired thrombophilic conditions. As expected, hereditary antithrombin, protein C, or protein S deficiencies were rare. Among hemorrhagic disorders, thrombocytopenia, platelet dysfunction, and von Willebrand disease or low von Willebrand factor levels were those factors most frequently associated with increased perioperative bleeding. CONCLUSIONS: Patients should be screened for elevated risk of thrombosis or bleeding before undergoing microsurgical breast reconstruction, and positive screening should prompt a complete hematologic evaluation. Interdisciplinary management of these disorders with a hematologist is essential to minimize risks and to obtain optimal reconstructive results. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, IV.

Safe mobilisation of transverse upper gracilis flap in patients with hip replacements.

BACKGROUND: The transverse upper gracilis (TUG) flap is easily harvested to recruit a fair volume of tissue from the inner upper thigh region, making it the second choice of certain authors. Hip replacement is deemed prohibitive due to positional requirements that predispose to anterior dislocation of prosthetic femoral heads. In this report, we describe a simple and safe way to raise TUG flap in patients with existing hip prostheses, detailing patient assessments, and technical variations in a limited case series. MATERIAL AND METHODS: A retrospective single cohort study was conducted on patient who underwent TUG flap-based reconstruction after hip replacement. Hip joint instability was assessed clinically and with CT. Flap harvesting was performed to prevent the extra-rotation of the femoral head by the thigh flex or dissecting the pedicle keeping the thigh straight. RESULT: Eleven patients were qualified for the study, and the flap raising time was superimposable to the conventional technique. Six flaps were elevated, while the thigh was kept in the flexed position without any extra-rotation, and the pedicle dissection was completed in 5 cases by keeping the thigh in the straight position. No intra- or postoperative hip dislocations resulted. All patients ambulated on mornings after surgery, returning to daily activities within 4 weeks. CONCLUSION: TUG flap is a viable alternative that is not necessarily prohibited by existing prosthetic hips. Careful patient assessment and positioning during surgery are key considerations for safe and successful procedures.

Comparing Seroma Formation at the Deep Inferior Epigastric Perforator, Transverse Musculocutaneous Gracilis, and Superior Gluteal Artery Perforator Flap Donor Sites after Microsurgical Breast Reconstruction.

Background Seroma formation is the most common donor site complication following autologous breast reconstruction, along with hematoma. Seroma may lead to patient discomfort and may prolong hospital stay or delay adjuvant treatment. The aim of this study was to compare seroma rates between the deep inferior epigastric perforator (DIEP), transverse musculocutaneous gracilis (TMG), and superior gluteal artery perforator (SGAP) donor sites. Methods The authors conducted a retrospective single-center cohort study consisting of chart review of all patients who underwent microsurgical breast reconstruction from April 2018 to June 2020. The primary outcome studied was frequency of seroma formation at the different donor sites. The secondary outcome evaluated potential prognostic properties associated with seroma formation. Third, the number of donor site seroma evacuations was compared between the three donor sites. Results Overall, 242 breast reconstructions were performed in 189 patients. Demographic data were found statistically comparable between the three flap cohorts, except for body mass index (BMI). Frequency of seroma formation was highest at the SGAP donor site (75.0%), followed by the TMG (65.0%), and DIEP (28.6%) donor sites. No association was found between seroma formation and BMI, age at surgery, smoking status, diabetes mellitus, neoadjuvant chemotherapy, or DIEP laterality. The mean number of seroma evacuations was significantly higher in the SGAP and the TMG group compared with the DIEP group. Conclusion This study provides a single center's experience regarding seroma formation at the donor site after microsurgical breast reconstruction. The observed rate of donor site seroma formation was comparably high, especially in the TMG and SGAP group, necessitating an adaption of the surgical protocol.

Dual pedicle epiphyseal transfer for paediatric bony sarcoma reconstruction: Technique and review of outcomes.

Skeletal reconstruction after tumour resection in paediatric patients is challenging. The resultant reconstruction needs to meet the demands of graft incorporation as well as the potential for growth. The vascularised fibular epiphyseal transfer (VFET) offers the potential for both. We retrospectively reviewed eight paediatric patients treated with VFET after bony tumour resection. All patients underwent a dual pedicle transfer with the peroneal artery for the diaphyseal blood supply and the recurrent branch of the anterior tibial artery for the physis. This is the largest series in literature for dual pedicle transfers for bony reconstruction. We present our surgical technique and outcomes in terms of functional limb salvage and growth.

Prepectoral versus subpectoral implant-based breast reconstruction after skin-sparing mastectomy or nipple-sparing mastectomy (OPBC-02/ PREPEC): a pragmatic, multicentre, randomised, superiority trial.

INTRODUCTION: The emphasis on aesthetic outcomes and quality of life (QoL) has motivated surgeons to develop skin-sparing or nipple-sparing mastectomy (SSM/ NSM) for breast cancer treatment or prevention. During the same operation, a so-called immediate breast reconstruction is performed. The breast can be reconstructed by positioning of a breast implant above (prepectoral) or below (subpectoral) the pectoralis major muscle or by using the patients' own tissue (autologous reconstruction). The optimal positioning of the implant prepectoral or subpectoral is currently not clear. Subpectoral implant-based breast reconstruction (IBBR) is still standard care in many countries, but prepectoral IBBR is increasingly performed. This heterogeneity in breast reconstruction practice is calling for randomised clinical trials (RCTs) to guide treatment decisions. METHODS AND ANALYSIS: International, pragmatic, multicentre, randomised, superiority trial. The primary objective of this trial is to test whether prepectoral IBBR provides better QoL with respect to long-term (24 months) physical well-being (chest) compared with subpectoral IBBR for patients undergoing SSM or NSM for prevention or treatment of breast cancer. Secondary objectives will compare prepectoral versus subpectoral IBBR in terms of safety, QoL and patient satisfaction, aesthetic outcomes and burden on patients. Total number of patients to be included: 372 (186 per arm). ETHICS AND DISSEMINATION: This study will be conducted in compliance with the Declaration of Helsinki. Ethical approval has been obtained for the lead investigator's site by the Ethics Committee 'Ethikkommission Nordwest- und Zentralschweiz' (2020-00256, 26 March 2020). The results of this study will be published in a peer-reviewed medical journal, independent of the results, following the Consolidated Standards of Reporting Trials standards for RCTs and good publication practice. Metadata describing the type, size and content of the datasets will be shared along with the study protocol and case report forms on public repositories adhering to the FAIR (Findability, Accessibility, Interoperability, and Reuse) principles. TRIAL REGISTRATION NUMBER: NCT04293146.

Abdominal perforator exchange flap (APEX): A classification of pedicle rearrangements.

INTRODUCTION: Abdominal-based reconstruction is the most commonly performed method for breast reconstruction after mastectomy using the patient's own tissues. DIEP flap has allowed to reduce the donor site morbidity but the incidence of bulging or hernia remains still high, especially when flap is based on multiple perforators. Abdominal Perforator Exchange flap (APEX) represents a further step forward in preserving the abdominal wall structures by disassembling the pedicle components and their reconstitution at the end of the dissection. In this study, we explore the possible anatomical configurations of perforators exchange for APEX, providing a simple classification of perforators reconstitution patterns and the possible clinical implications. MATERIALS AND METHODS: A retrospective study was conducted on patients who received APEX flap for abdominal based breast reconstruction. Preoperative CT scans and procedure descriptions were analyzed to identify the vascular patterns during flap harvesting and the pedicle reconstitution sites. The onset of abdominal wall and flap related complications were investigated. RESULTS: APEX flap was performed on 51 women and four vascular patterns were identified. We identified the Type A pattern in 36 cases (70.6%), the Type B pattern in 8 (15.7%), and the Type C pattern in 5 (9.8%). We performed an extra-anatomical reanastomosis (Type D) in only two case (3.9%) (p = .09). We recorded anastomotic problems in five pedicles' reconstitution and the odds ratio showed a possible correlation between the localization of pedicle division and the anastomosis problems (p > .05). No total or partial flap loss was recorded during this study. Marginal fat necrosis was clinically observed in three cases, which had very large flaps. No bulging or hernia was recorded. CONCLUSION: Our perforators exchange classification for abdominal-based flap helps clinician in planning the surgery and also in describing the procedure easily allowing a more efficient communication. This classification could be used to approach perforator flaps with multiple vessels at other anatomical locations as well.

Donor site aesthetics and morbidity after DIEP flap breast reconstruction-A retrospective multicenter study.

The deep inferior epigastric artery perforator flap (DIEP) has gained widespread popularity in autologous breast reconstruction due to its natural aesthetic results and muscle-sparing design. However, donor site results regarding aesthetic outcome are often less favorable. We therefore aimed to identify crucial factors that might increase the risk for abdominal bulging and an impaired aesthetic appearance. We conducted a multicenter study evaluating all patients receiving autologous breast reconstruction using a DIEP flap between 2013 and 2017. Medical records were analyzed with special attention to flap technique, number of perforators, localization of perforator, and donor site complications. In addition, the aesthetic appearance of the abdominal donor site was evaluated by blinded clinicians at one-year follow-up. A total of 242 patients underwent DIEP flap breast reconstruction. Abdominal bulging occurred in 7%. Further subgroup analysis revealed a significant correlation between abdominal bulging and two or more perforators (P = .003), the use of lateral row perforators (P = .009), and a higher BMI (P = .002). Obesity (P = .003) and higher patient's age (P = .003) could be identified as risk factors for an undesirable appearance of the donor site. We recommend the use of a medial-row single perforator whenever possible in order to optimize donor site morbidity and decrease the risk of abdominal bulging. Proper patient selection and careful donor site closure following a standardized approach should be performed to limit the risk of aesthetically undesirable results.

Diep Flap Volume Augmentation: Literature Review and "Calzone" Flap Shaping Technique.

Breast reconstruction with DIEP flap is a well-accepted and well-established technique for autologous breast reconstruction. In the past, this reconstructive option was typically offered to a limited group of patients as previous surgeries or low BMI were considered to be an obstacle to the success of the procedure or for the achievement of a satisfactory cosmetic outcome due to the lack of available tissue. Nowadays, this does not correspond to truth anymore and DIEP flaps are performed routinely on slender patients and on women who have undergone previous liposuction or abdominal surgeries. This paper analyzes current surgical options for volume recruitment in patients with scanty abdominal tissue or with abdominal scars and presents our standardized approach for DIEP volume augmentation with the "Calzone style" bipedicled DIEP flap.

Evaluation of Sensation on Mastectomy Skin Flaps following Immediate Breast Reconstruction.

BACKGROUND: During a subcutaneous mastectomy, nerves are severed and patients lose sensation on the breast skin. The aim of this study is to investigate factors that have impact on the sensation of the mastectomy flaps and patients' own perception regarding overall breast skin sensation. PATIENTS AND METHODS: Patients who have undergone skin sparing or nipple sparing mastectomy with immediate reconstruction with either an implant or autologous tissue were included. Sensory assessment was performed at least 12 months after surgery using Semmes-Weinstein monofilaments (Aesthesio, San Jose, CA). The breast envelope was divided into four quadrants, and one measurement from each quadrant was recorded. Patients were also asked to fill out a questionnaire before the examination. RESULTS: A total of 59 breasts in 40 women were examined. In lower medial quadrant, significantly more patients reported "no sensation" in the radiated group than the nonradiated group. In upper medial quadrant and lower lateral quadrant, patients with NSM reported better sensation than patients with skin sparing mastectomy (SSM). CONCLUSION: Vascularized tissue did not improve sensory recovery. There was no relationship between sensation and the preoperative cup size and the number of revision surgeries. Irradiation was associated with higher sensory thresholds in lower medial quadrant. Nipple sparing mastectomy was associated with lower sensory thresholds in two quadrants compared to SSM. Independent of all variables none of the patients reported normal sensation.

Preoperative Perforator Mapping in SGAP Flap: Does Magnetic Resonance Imaging Make the Difference?

BACKGROUND: Preoperative vascular mapping has emerged as an excellent adjunct to perforator flap surgery, improving operative time while aiding the surgeon in the selection of the ideal perforator. This study evaluated the effect of preoperative vascular mapping by magnetic resonance imaging to identify tissue for a superior gluteal artery perforator (SGAP) flap on total operative time and compared radiologic mapping by magnetic resonance imaging with Doppler ultrasonography for perforator localization. The authors also investigated whether drawing the flap according to magnetic resonance imaging perforator localization or tissue availability affected the outcome of the donor site. METHODS: A prospective study was performed on patients undergoing SGAP flap breast reconstruction. Patients were randomized into two groups. One group received preoperative magnetic resonance imaging for flap tissue planning based on localization of the perforator. The other group received flap planning based on tissue availability and then underwent external Doppler ultrasonography to identify the dominant perforator. An ad hoc outcome scale was created to evaluate outcomes of the donor sites. RESULTS: Preoperative vascular mapping by magnetic resonance imaging or external Doppler ultrasonography was performed the day of surgery on 35 and 27 patients, respectively. The mean flap elevation times of the imaging patients versus the ultrasonography patients were 252 and 228 minutes, respectively. The differences between flap elevation times and cosmetic outcomes for the two patient groups were not significant. CONCLUSION: The authors' findings indicate that the use of magnetic resonance imaging for SGAP flap planning did not reduce operative time, and that donor-site outcomes were not affected by the modality used for preoperative perforator mapping. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

A systematic review of donor site aesthetic and complications after deep inferior epigastric perforator flap breast reconstruction.

BACKGROUND: The deep inferior epigastric perforator flap (DIEP) has gained widespread popularity in autologous breast reconstruction due to its natural aesthetic results and muscle-sparing design. However, donor site results regarding aesthetic outcome are often less favorable. Despite several studies on surgical technique and improvements of flap harvest, only a small number of studies addressing donor site aesthetic exist. METHODS: A systematic review was performed on donor site aesthetic after DIEP flap harvest according to the PRISMA guidelines. Secondary interests were abdominal wall morbidity and complication rates in general. The following electronic databases were included to identify relevant studies: Medline, Embase, PubMed, Cochrane, and Web of Science. RESULTS: The search yielded 95 articles for full-text analysis, with only four key studies found on donor site aesthetic specifically. Regarding complication rates, the overall rate of abdominal hernia ranges from 0 to 7.1%. Abdominal bulging occurs in 2.3% to 33%. Besides abdominal wall integrity, wound dehiscence (12-39%), seroma (1-48%), hematoma (1-15%), infections (1-12%), fat necrosis (0-11%) and umbilical necrosis (2-3%) significantly impair donor site aesthetic. CONCLUSIONS: This systematic review reveals that the topic of donor site aesthetic and potential improvement of results has largely been neglected in the past decade. This study provides a thorough evaluation of potential problems that plastic surgeons may encounter and includes recommendations to improve results.

Breast reconstruction with Superior Gluteal Artery Perforator free flap: 8 years of experience.

INTRODUCTION: The SGAP flap represents an alternative for autologous breast reconstruction when DIEP is not available. In this article, we report eight years of experience in breast reconstruction using SGAP free flap and discuss our results, how our procedures have evolved, the outcomes and complications rates and how to perform this procedure efficiently while managing the challenges inherent to this type of flap. MATERIALS AND METHODS: A retrospective study was conducted from June 2009 and June 2017. Patients requiring SGAP flap breast reconstruction were enrolled. Donor site availability was categorised into 4 classes according to the availability of tissue. An ad hoc outcome scale was created to standardise the results and ensure data comparability. RESULTS: A total of 119 patients were enrolled in the study. We recorded 18 cases of excellent results, 57 good, 30 moderate and 14 poor. Our results show that donor site class impacts complications and patient outcome. The odds ratio analysis demonstrated that the third class donor site has a protective impact on complications and has a direct correlation with good patient outcomes. CONCLUSIONS: SGAP flap can provide very good outcomes, and it should be considered as another option when DIEP is not available. Patient selection and efficiency are the keys to achieve optimal results and minimise complications. Although this flap is available for patients with a low BMI, the donor site has to provide enough tissue to achieve symmetry with the contralateral breast and allow a tension-free closure without contour deformity.
