Preoperative Risk Factors for Lymphedema in Inflammatory Breast Cancer.

BACKGROUND: Prophylactic lymphatic bypass or LYMPHA (LYmphatic Microsurgical Preventive Healing Approach) is increasingly offered to prevent lymphedema following breast cancer treatment, which develops in up to 47% of patients. Previous studies focused on intraoperative and postoperative lymphedema risk factors, which are often unknown preoperatively when the decision to perform LYMPHA is made. This study aims to identify preoperative lymphedema risk factors in the high-risk inflammatory breast cancer (IBC) population. METHODS: Retrospective review of our institution's IBC program database was conducted. The primary outcome was self-reported lymphedema development. Multivariable logistic regression analysis was performed to identify preoperative lymphedema risk factors, while controlling for number of lymph nodes removed during axillary lymph node dissection (ALND), number of positive lymph nodes, residual disease on pathology, and need for adjuvant chemotherapy. RESULTS: Of 356 patients with IBC, 134 (mean age: 51 years, range: 22-89 years) had complete data. All 134 patients underwent surgery and radiation. Forty-seven percent of all 356 patients (167/356) developed lymphedema. Obesity (body mass index > 30) (odds ratio [OR]: 2.7, confidence interval [CI]: 1.2-6.4, p = 0.02) and non-white race (OR: 4.5, CI: 1.2-23, p = 0.04) were preoperative lymphedema risk factors. CONCLUSION: Patients with IBC are high risk for developing lymphedema due to the need for ALND, radiation, and neoadjuvant chemotherapy. This study also identified non-white race and obesity as risk factors. Larger prospective studies should evaluate potential racial disparities in lymphedema development. Due to the high prevalence of lymphedema, LYMPHA should be considered for all patients with IBC.

Impact of Prepectoral vs. Subpectoral Tissue Expander Placement on Post-mastectomy Radiation Therapy Delivery: A Retrospective Cohort Study.

Background: Implant-based reconstruction is the most common method of postmastectomy reconstruction. Many patients require postmastectomy radiation (PMRT). Tissue expanders (TEs), typically inserted as a first stage, have historically been placed subpectorally. More recently, prepectoral reconstruction has gained popularity, but its impact on PMRT is unknown. Prior studies focus on complication rates and aesthetic outcomes. This study examines whether there is a difference in radiation dosimetry among patients undergoing prepectoral versus subpectoral TE reconstruction. Methods: Electronic medical records and radiation plans of 50 patients (25 prepectoral, 25 subpectoral) who underwent mastectomy with immediate TE reconstruction at our institution or affiliate site were reviewed. Pectoralis major muscle and chest wall structures were contoured and mean percentage volumes of these structures receiving less than 95%, 100%, and more than 105% target radiation dose were calculated, as were heart and ipsilateral lung doses. Welch two sample t test, Fisher exact test, and Pearson chi-squared tests were performed. Results: The groups had comparable patient and tumor characteristics and underwent similar ablative and reconstructive procedures and radiation dosimetry. Subpectoral patients had larger mean areas receiving less than 95% target dose ("cold spots"); prepectoral patients had larger mean areas receiving greater than 105% ("hot spots") and 100% target doses. There were no differences in chest wall, heart, and lung doses. Conclusions: Our results demonstrate an increased mean percentage area of pectoralis cold spots with subpectoral reconstruction and increased area of hot spots and 100% dose delivery to the pectoralis in prepectoral patients. Larger studies should analyze long-term effects of prepectoral reconstruction on radiation dosing and recurrence rates.

Evaluation of Artificial Intelligence-generated Responses to Common Plastic Surgery Questions.

Background: Artificial intelligence (AI) is increasingly used to answer questions, yet the accuracy and validity of current tools are uncertain. In contrast to internet queries, AI generates summary responses as definitive. The internet is rife with inaccuracies, and plastic surgery management guidelines evolve, making verifiable information important. Methods: We posed 10 questions about breast implant-associated illness, anaplastic large lymphoma, and squamous carcinoma to Bing, using the "more balanced" option, and to ChatGPT. Answers were reviewed by two plastic surgeons for accuracy and fidelity to information on the Food and Drug Administration (FDA) and American Society of Plastic Surgeons (ASPS) websites. We also presented 10 multiple-choice questions from the 2022 plastic surgery in-service examination to Bing, using the "more precise" option, and ChatGPT. Questions were repeated three times over consecutive weeks, and answers were evaluated for accuracy and stability. Results: Compared with answers from the FDA and ASPS, Bing and ChatGPT were accurate. Bing answered 10 of the 30 multiple-choice questions correctly, nine incorrectly, and did not answer 11. ChatGPT correctly answered 16 and incorrectly answered 14. In both parts, responses from Bing were shorter, less detailed, and referred to verified and unverified sources; ChatGPT did not provide citations. Conclusions: These AI tools provided accurate information from the FDA and ASPS websites, but neither consistently answered questions requiring nuanced decision-making correctly. Advances in applications to plastic surgery will require algorithms that selectively identify, evaluate, and exclude information to enhance the accuracy, precision, validity, reliability, and utility of AI-generated responses.

Predictors of gastrostomy tube placement in patients with head and neck cancer undergoing resection and flap-based reconstruction: systematic review and meta-analysis.

BACKGROUND: Nutritional status may be impaired in patients with head and neck cancer undergoing surgical treatment, often necessitating gastrostomy tube (G-tube) placement. Identifying which patients will require a G-tube remains a challenge. This study identifies predictors of G-tube requirement in patients undergoing tumor resection and reconstruction with pedicled or free flaps. METHODS: Systematic review of the PubMed, Cochrane, and Scopus databases was performed of English language articles, discussing risk factors of perioperative G-tube placement among patients >18 years. Data on patient, tumor, and treatment factors, as well as need for G-tube, were collected. Univariable meta-analysis was conducted to identify predictors for G-tube placement. RESULTS: Eleven studies (1,112 patients) met inclusion criteria. Overall pooled prevalence of postoperative G-tube placement was 25%. Patients with advanced cancer stage IV/recurrence were more likely to require a G-tube (OR 2.81 [CI 1.03-7.69]; p<0.05), as were those who had undergone preoperative radiation (OR 3.55 [CI 2.03-6.20], p<0.05). Reconstruction with a radial forearm free flap was associated with a lower need for G-tube versus rectus abdominis (OR 0.25 [CI 0.08-0.83], p=0.02) and latissimus dorsi flap (OR 0.21 [CI 0.04-1.09], p=0.06). There was no difference in G-tube placement between those receiving pedicled flaps versus free flaps (OR 1.54 [CI 0.38-6.20], p=0.54). CONCLUSIONS: Among patients with head and neck cancer undergoing resection with immediate pedicled or free flap reconstruction, advanced tumor stage and history of prior radiation therapy are associated with increased likelihood of G-tube placement. More randomized controlled trials are needed to develop a decision-making algorithm.

Outcomes of Extended Pedicle Technique vs Free Nipple Graft Reduction Mammoplasty for Patients With Gigantomastia.

BACKGROUND: Optimal reduction mammoplasty techniques to treat patients with gigantomastia have been debated and can involve extended pedicles (EP) or free nipple grafts (FNG). OBJECTIVES: The authors compared clinical, patient-reported, and aesthetic outcomes associated with reduction mammoplasty employing EP vs FNG. METHODS: A multi-institutional, retrospective study of adult patients with gigantomastia who underwent reduction mammoplasty at 2 tertiary care centers from 2017 to 2020 was performed. Gigantomastia was defined as reduction weight >1500 g per breast or sternal notch-to-nipple distance ≥40 cm. Surgeons at 1 institution employed the EP technique, whereas those at the other utilized FNG. Baseline characteristics, preoperative and postoperative BREAST-Q, and clinical outcomes were collected. Aesthetic outcomes were assessed in 1:1 propensity score-matched cases across techniques. Preoperative and postoperative photographs were provided to reviewers across the academic plastic surgery continuum (students to faculty) and non-medical individuals to evaluate aesthetic outcomes. RESULTS: Fifty-two patients met the inclusion criteria (21 FNG, 31 EP). FNG patients had a higher incidence of postoperative cellulitis (23% vs 0%, P < 0.05) but no other differences in surgical or medical complications. Baseline BREAST-Q scores did not differ between groups. Postoperative BREAST-Q scores revealed greater satisfaction with the EP technique (P < 0.01). The aesthetic assessment of outcomes in 14 matched pairs of patients found significantly better aesthetic outcomes in all domains with the EP procedure (P < 0.05), independent of institution or surgical experience. CONCLUSIONS: This multi-institutional study suggests that, compared with FNG, the EP technique for reduction mammoplasty provides superior clinical, patient-reported, and aesthetic outcomes for patients with gigantomastia.

Magnetic Resonance Imaging Screening after Silicone Implant Breast Surgery: Patient Survey of Adherence to U.S. Food and Drug Administration Recommendations.

BACKGROUND: The U.S. Food and Drug Administration recommends women with silicone breast implants undergo magnetic resonance imaging surveillance to detect asymptomatic rupture. Screening is costly and often not covered by insurance. The authors assessed awareness of and adherence to these recommendations among patients with silicone breast implants. METHODS: The authors searched electronic medical records for patients aged 18 years or older with silicone breast implants placed between 2011 and 2016. Consenting patients were surveyed by telephone using a standardized script to assess awareness of U.S. Food and Drug Administration recommendations, whether they had undergone magnetic resonance imaging screening, and barriers to testing. Patients who declined to participate or could not be contacted were excluded. Demographics and operative data were collected. Odds ratios were calculated with one-sample 95 percent confidence intervals, and Fisher exact tests of independence were conducted under assumptions of normality. Multivariable logistic regression analysis was performed to test for confounding. RESULTS: Of 370 patients meeting inclusion criteria, 109 consented to participate. Adherence to U.S. Food and Drug Administration recommendations was 5.9 percent (95 percent CI, 0.15 to 28.7 percent). There was no difference in adherence between patients undergoing cosmetic versus reconstructive surgery ( p = 1.00; OR, 0.80; 95 percent CI, 1.17 to 2.93), having health insurance ( p = 0.58), or residing in a county with median annual household income greater than that of the state of residence ( p = 0.33). CONCLUSIONS: A small proportion of respondents had undergone magnetic resonance imaging in accordance with U.S. Food and Drug Administration recommendations. Low adherence highlights a potential limitation of current federal surveillance recommendations. Additional research is needed to better characterize adherence to magnetic resonance imaging surveillance recommendations, identify barriers to implementation, and determine whether this recommendation remains valid.

BRCA2-associated Breast Cancer in Transgender Women: Reconstructive Challenges and Literature Review.

Breast cancer in trans women is rare. Only 21 cases have been reported worldwide. Multidisciplinary teams must balance oncologic treatment with patient goals. Here we describe a case of invasive ductal carcinoma in a transgender woman who was found to have a BRCA2 gene mutation. A shared decision-making process led to the patient undergoing bilateral nipple-sparing mastectomy with immediate tissue expander placement. Later findings prompted discussions about adjuvant chemotherapy and radiation. Additionally, we discuss the complexities associated with reconstructing a transfeminine chest.

The Effects of Cannabis: Implications for the Surgical Patient.

Cannabis use is increasingly prevalent. Cannabinoid receptors regulate pro-inflammatory cytokines, and compounds in marijuana exert diverse physiologic effects. As more patients use cannabis, clinicians should recognize implications of perioperative cannabis use. Although the role of cannabis use in perioperative pain control has been explored, little is known about its effect on perioperative wound healing or on hematologic, pulmonary, and cardiovascular physiology. METHODS: We searched PubMed for English-language articles related to cannabis (ie, marijuana, cannabidiol oil, and tetrahydrocannabinol) and wound healing, cardiovascular, pulmonary, or hematologic outcomes, and surgery. Titles and abstracts were reviewed, and relevant articles were analyzed. Human, animal, and pathology studies were included. Editorials, case reports, and review articles were excluded. RESULTS: In total, 2549 wound healing articles were identified; 5 human studies and 8 animal/pathology studies were included. Results were conflicting. An estimated 2900 articles related to cardiovascular effects were identified, of which 2 human studies were included, which showed tetrahydrocannabinol and marijuana caused tachycardia. A total of 142 studies regarding pulmonary effects were identified. Three human studies were included, which found no difference in respiratory complications. In total, 114 studies regarding hematologic effects were identified. The 3 included human studies found conflicting venous thromboembolism risks. The overall study quality was poor. Information about dose/duration, administration route, and follow-up was reported with variable completeness. CONCLUSIONS: Surgeons should consider effects of cannabis in the perioperative setting. Little is known about its perioperative effects on wound healing, or on cardiovascular, pulmonary, and hematologic physiology. Further research should elucidate the effects of administration route, dose, and timing of cannabis use among surgical patients.

Perineal reconstruction following abdominoperineal resection: Comprehensive review of the literature.

Abdominoperineal resection (APR) in patients with anorectal carcinomas may involve flap-based perineal reconstruction techniques, such as rectus abdominis, myocutaneous, gracilis, and gluteal flaps. There is no consensus on the optimal approach. We evaluated the outcomes of perineal reconstruction following APR in the literature and identified a predominance of abdominal-based approaches, though overall outcomes were similar compared with thigh or perineal-based options. Statistical power to detect small differences in outcomes is limited, however, due to the retrospective design, relatively short-term follow-up, and potential selection bias based on morbidities associated with reconstructive techniques. Lacking randomized studies to define optimum approaches to perineal reconstruction, clinicians should individualize surgical strategy.

Does the timing of postoperative showering impact infection rates? A systematic review and meta-analysis.

INTRODUCTION: Optimum timing of postoperative showering varies. Earlier showering improves patient satisfaction, but the impact of the timing of showering on postoperative infection is unclear. We conducted a systematic literature review and meta-analysis to investigate the outcomes of various postoperative showering practices. METHODS: We searched PubMed to identify relevant human clinical studies in English, and searched these for additional references. Articles were reviewed for patient demographics, surgical specialty and procedure, wound closure method, placement of drains, showering protocol, and rates of infection and complications. Only randomized controlled trials were analyzed. A random-effects meta-analysis model was used to determine overall infection and complication rates between patients allowed to shower within the first 48 h postoperatively or later. RESULTS: Out of 357 studies, seven and five were included in the infection and complications rate meta-analyses, respectively. A total of 1,881 and 958 patients were included in each analysis; 605 and 477 patients in each analysis were allowed to shower on or before postoperative day 2 ("early"), while the remainder were prohibited from showering until postoperative day 3 to beyond one week ("delayed") postoperatively. There was no difference in infection (p = 0.45, [-0.0052, 2 × 0.007 95% CI]) or complication rate (p = 0.36, [-0.0046, 2 × 0.005 95% CI]) with earlier vs. delayed showering protocols. CONCLUSION: Published literature demonstrates no increase in the overall rate of wound infections or complications when patients showered earlier in the postoperative period. Additional randomized studies are needed to determine the ideal time for postoperative showering. These data should be considered by surgeons while determining when to permit patients to shower after surgery.

Evaluating Postoperative Narcotic Use in Prepectoral Versus Dual-plane Breast Reconstruction Following Mastectomy.

BACKGROUND: The majority of postmastectomy breast reconstruction performed in the United States is device-based. Typically, a tissue expander or implant is placed in the dual-plane (ie, subpectoral). Prepectoral breast reconstruction with acellular dermal matrices following mastectomy is a relatively new technique that has favorable outcomes with minimal complications and satisfactory aesthetic results. Few studies have compared opioid use between the 2 approaches. This study compares duration of postoperative opioid use among patients undergoing prepectoral device-based breast reconstruction with those in whom dual-plane devices were placed. METHODS: We reviewed the records of adult female patients aged 18 years or older who underwent prepectoral or dual-plane device-based breast reconstructions following mastectomy by one of the 2 plastic surgeons (A.M. or M.V.) from 2015 to 2017 at a large tertiary care hospital. Patients with a history of substance abuse, chronic pain, or who were already receiving opioid medication were excluded. Electronic medical records were reviewed and patient surveys were conducted during postoperative visits to determine postoperative opioid requirements. RESULTS: During the study period, 58 patients underwent dual-plane breast reconstruction and 94 underwent prepectoral reconstruction. Demographics and comorbidities of the groups were similar. By multivariate regression analysis, the prepectoral reconstruction group required 33% fewer days on opioid analgesic medication (P = 0.016) and were 66% less likely to require opioid prescription refills (P = 0.027). There were no statistically significant differences in other outcomes or complications. CONCLUSION: Patients undergoing prepectoral tissue expander or implant-based reconstruction required fewer days of opioid pain medication than those managed with the dual-plane technique.

Correction of the tuberous breast deformity in a prepubescent male patient: A surgical approach to an unusual problem.

PURPOSE: The management of the tuberous breast deformity in the female patient is well described. However, the presence of this variant in male patients is particularly rare, and few reports on the management of this condition are available. CASE PRESENTATION: A 12-year-old prepubescent male with bilateral gynecomastia and tuberous breast deformities was referred to our department for treatment. Our surgical management, including free nipple areolar complex harvest, mastectomy, removal of excess skin and subsequent nipple grafting, is presented in detail. We observed a cosmetically acceptable result with restoration of a masculine-appearing nipple-areolar complex and good patient satisfaction at 6-month follow-up. CONCLUSIONS: Tuberous breast deformities in male patients are rare. Our treatment of a prepubertal male patient with this deformity using mastectomies and free nipple areolar complex grafting provided a cosmetically acceptable result. Here, we review the current literature on tuberous breast deformities in males and describe our approach to treatment.

Dogma without Data: A Clinical Decision-Making Tool for Postoperative Blood Cultures.

Bacteremia is a worrisome postoperative complication and blood cultures (BCx) are often nondiagnostic. We previously reported a 4 per cent overall yield of positive cultures in postoperative patients. To reduce unnecessary testing, we present a predictive model to identify patients in whom growth of pathogens is unlikely and provide a clinical decision-making guide. Retrospective analysis of nonpregnant patients ≥18 years who had BCx within 10 days postoperatively was performed. Generalized linear mixed models identified clinical predictors of high- and low-yield cultures. A clinical algorithm was created using significant predictors, and positive predictive value, negative predictive value, sensitivity, and specificity calculated. Among 1759 BCx, hypotension, maximum temperature ≥101.5 °F within 24 hours of culture, and culture collected after postoperative day (POD) two were statistically significant predictors of positive cultures. Forty nine per cent of BCx were sent ≤ POD 2, and <1 per cent of these were positive. When all three criteria were met, the probability of a positive culture increased to 17 per cent. When absent, the probability of a negative culture was 99 per cent. When applied to the initial data set, the model resulted in 85 per cent reduction of cultures with 9 per cent yield of positive cultures. Drawing BCx based on a single predictor is inadequate. Reducing the number of cultures reflexively ordered within the first two POD could significantly reduce the number of unnecessary BCx. Several clinical features identified patients most likely to have positive BCx within the first 10 POD and could reduce unnecessary BCx. This model should be validated in an independent, prospective cohort.

Re-evaluating the Lejour Technique for Breast Reduction in Patients with Macromastia.

BACKGROUND: Limited scar Lejour technique for breast reduction is conventionally used to remove less than 500 g of breast tissue per breast, but is effective for greater macromastia. Plastic surgery residents gain limited experience with this technique, and it is infrequently performed in the United States. To understand technique selection, we surveyed board-certified plastic surgeons and compared outcomes with the Lejour technique in 1 practice to those with other methods. METHODS: We surveyed American Society of Plastic Surgeons members about techniques for breast reduction and compared outcomes with procedures performed by various techniques by a single surgeon (M.C.). RESULTS: Of 321 survey respondents, 33% reported formal training in the Lejour technique. Over 70% used mainly the inferior pedicle Wise procedure; 14% used mainly the Lejour or modified Lejour technique. In a series of reduction mammaplasties by 1 surgeon in 119 patients between 1997 and 2006, 14 underwent inferior pedicle Wise pattern and 105 involved the Lejour technique. Mean tissue mass removal was 1,136 g/breast (range, 170-4,050 g). Major complications occurred in 1.74% overall, and 0% and 1.9% for the Wise and Lejour techniques, respectively (P = 0.46). CONCLUSIONS: Although most American Society of Plastic Surgeons respondents were not formally trained in the Lejour technique and seldom perform the procedure, it can be employed for reduction mammaplasty with no greater risk of complications than the Wise method. The Lejour technique should be incorporated during residency training as an alternative for reduction mammaplasty.

Computer-Aided Surgical Simulation in Head and Neck Reconstruction: A Cost Comparison among Traditional, In-House, and Commercial Options.

BACKGROUND: Computer-aided surgical simulation (CASS) has redefined surgery, improved precision and reduced the reliance on intraoperative trial-and-error manipulations. CASS is provided by third-party services; however, it may be cost-effective for some hospitals to develop in-house programs. This study provides the first cost analysis comparison among traditional (no CASS), commercial CASS, and in-house CASS for head and neck reconstruction. METHODS: The costs of three-dimensional (3D) pre-operative planning for mandibular and maxillary reconstructions were obtained from an in-house CASS program at our large tertiary care hospital in Northern Virginia, as well as a commercial provider (Synthes, Paoli, PA). A cost comparison was performed among these modalities and extrapolated in-house CASS costs were derived. The calculations were based on estimated CASS use with cost structures similar to our institution and sunk costs were amortized over 10 years. RESULTS: Average operating room time was estimated at 10 hours, with an average of 2 hours saved with CASS. The hourly cost to the hospital for the operating room (including anesthesia and other ancillary costs) was estimated at $4,614/hour. Per case, traditional cases were $46,140, commercial CASS cases were $40,951, and in-house CASS cases were $38,212. Annual in-house CASS costs were $39,590. CONCLUSIONS: CASS reduced operating room time, likely due to improved efficiency and accuracy. Our data demonstrate that hospitals with similar cost structure as ours, performing greater than 27 cases of 3D head and neck reconstructions per year can see a financial benefit from developing an in-house CASS program.

Clinical Predictors of Positive Postoperative Blood Cultures.

OBJECTIVE: To define clinical features of surgical patients in whom postoperative blood cultures are likely to identify pathogens. BACKGROUND: Bacteremia is a worrisome postoperative complication and blood cultures (BCx) are routinely used for evaluation of postoperative bacteremia, but are costly and not always diagnostic. Better methods are needed to select patients in whom BCx identify pathogens. METHODS: We reviewed records of patients ≥18 years old with BCx drawn ≤10 days after surgery in 2013 seeking independent predictors of positive cultures by simple and multiple logistic regression models with statistical significance at α = 0.05. RESULTS: Of 1804 BCx, excluding contaminants yielded 1780 cultures among 746 patients for analysis. The yield was low, with only 4% identifying potential pathogens. Positive BCx were most common after cardiac, ear/nose/throat, obstetric, and urologic procedures [odds ratio (OR) =10.3, P < 0.001 vs low-yield procedures: eg, gynecologic, neurosurgical, plastic surgical, podiatric, transplant]. Cultures more often grew pathogens when drawn in association with higher peak temperature (Tmax, P = 0.001) and longer interval from procedure to Tmax (P = 0.001). Antibiotic therapy at time of culture reduced yield (2.9% with vs 5.5% without antibiotics, P = 0.007). Multivariable logistic regression analysis found antibiotics at culture, procedure specialty, Tmax, and postoperative timing of Tmax were associated with blood culture results. CONCLUSIONS: Ordering blood cultures based on fever or another single predictor inconsistently identifies pathogens. Our dataset, the largest available, identify clinical predictors in the first 10 postoperative days to guide identification of patients with bacteremia.

SPY Elite's Ability to Predict Nipple Necrosis in Nipple-Sparing Mastectomy and Immediate Tissue Expander Reconstruction.

BACKGROUND: Nipple-sparing techniques have improved the aesthetics of reconstruction following mastectomy, but nipple necrosis complicates up to 37% of procedures, distressing patients, delaying adjuvant therapy, and compromising outcomes. No method reliably detects nipple necrosis better than clinical assessment of tissue perfusion. We prospectively assessed the accuracy of intraoperative indocyanine green laser angiography to predict nipple necrosis. METHODS: Twenty consecutive women undergoing immediate tissue expander breast reconstruction following 32 nipple-sparing mastectomies underwent indocyanine green fluorescence imaging to assess nipple perfusion immediately before and after intraoperative tissue expansion. Imaging findings were correlated with postoperative nipple viability. RESULTS: Among the 32 nipple-sparing mastectomies (8 unilateral, 12 bilateral) in 20 women (mean age, 48 years), partial or full-thickness necrotic changes developed in 3 breasts of 2 patients (10%). Imaging identified impaired perfusion and predicted necrosis in these cases. CONCLUSIONS: In this initial series, intraoperative indocyanine green laser angiography correctly identified patients who developed nipple necrosis during mastectomy and tissue expander breast reconstruction.

The vastus lateralis free flap for lower extremity gustilo grade III reconstruction.

BACKGROUND: Orthopedic trauma patients with Gustilo grade III injuries to the distal third of lower extremity present challenges to optimum reconstructive management. There is no consensus on the ideal autologous tissue for transfer in large lower extremity defect reconstruction. We present a large case series utilizing the vastus lateralis (VL) free flap for lower extremity Gustilo grade III reconstruction. PATIENTS AND METHODS: This is a case series of patients who underwent VL free tissue transfer for Gustilo grade III injuries. A total of 38 free tissue transfers were performed for lower extremity reconstruction, 19 of which were VL flaps. Mean interval between injury and reconstruction was 46 days (range 7-240 days). RESULTS: The mean wound size was 11.37 cm x 11.42 cm and all cases underwent delayed reconstruction. Seven day flap viability was 100% and 30-day flap viability was 17/19 (89%). There were six complications: two hematomas requiring drainage, one flap dehiscence, one distal flap loss requiring a reverse saphenous vein graft extension, and two complete flap losses. Of the two failed flaps, one was attributed to heparin-induced thrombocytopenia and the other to venous congestion complicated by methicillin-resistant Staphylococcus aureus infection. CONCLUSIONS: The VL free flap is a reliable and versatile flap that can be tailored and tangentially thinned to match the shape and size of a defect, and the long pedicle allows the surgeon to stay away from the zone of injury. This flap should be strongly considered for lower extremity reconstruction, especially in salvage operations for large defects. © 2015 Wiley Periodicals, Inc. Microsurgery 37:212-217, 2017.
