RESUMO

BACKGROUND: Breast cancer-related lymphedema (BRCL) is a potential sequela of high-risk breast cancer treatment. Preventive treatment with immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has emerged as the standard of care; however, there is relatively little known about factors that may contribute to procedural failure. METHODS: A retrospectively maintained, institutional review board-approved study followed patients who underwent ILR at the time of ALND at our tertiary care center between May 2018 and May 2023. Patients who presented for at least one follow-up visit in our multidisciplinary lymphedema clinic met the criteria for inclusion. Patients who developed lymphedema despite ILR and potential contributing factors were further explored. RESULTS: 349 patients underwent ILR at our institution between May 2018 and May 2023. 341 of these patients have presented for follow-up in our multidisciplinary lymphedema clinic. 32 (9.4%) patients developed lymphedema despite ILR. This cohort was significantly more likely to be obese (56% vs 35%, P = 0.04). Multivariate logistic regression demonstrates increased odds of procedural failure in patients with a body mass index (BMI) ≥30 kg/m2 (odds ratio 2.6 [1.2-5.5], P = 0.01). CONCLUSION: These data comment upon our institutions outcomes following ILR. Patients who develop lymphedema despite ILR tend to have a higher BMI, with a significantly increased risk in patients with a BMI of 30 or greater. Consideration of these data is critical for preprocedural counseling and may support a BMI cutoff when considering candidacy for ILR going forward, as well as when optimizing failures for secondary lymphedema procedures.

RESUMO

Background: Abdominal donor site complications in bilateral pedicled transverse rectus abdominis muscle (TRAM) have been a concern when compared with bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study aimed to assess the strength, endurance, and motor control in patients undergoing DIEP and TRAM flaps. Methods: A prospective, cohort study was performed at a single institution including patients who underwent pedicled TRAM and DIEP flap reconstruction after mastectomy from August 2017 to August 2018. Patients underwent pre- and postoperative testing involving rectus abdominis, prone plank, side bridge, and trunk flexor tests. Descriptive analyses and multivariate linear regressions were performed. Results: The final analysis included a total of 9 patients, 4 of whom underwent TRAM flap reconstruction while 5 underwent DIEP flap reconstruction. The tests were not statistically significant between the TRAM versus DIEP groups, including rectus abdominis mean time decrease (0.25 vs 0.60 sec, P = .51), prone plank time increase (1.38 vs 1.38 sec, P = .51), right side bridge time increase (7.54 sec vs 32.15 sec, P = 1.00), left side bridge time increase (2.14 vs 44.5 sec, P = .37), and trunk flexor time decrease (4.68 vs 1.68 sec, P = .44). Overall complications were similar between the 2 groups. Conclusions: No significant difference in abdominal donor site morbidity was found when comparing the 2 groups. This article provides a point of conversation with patients when discussing available reconstruction options.

RESUMO

Background: First described by Michal et al in 1972, penile revascularization for vasculogenic impotence and its outcomes has been scarcely reported in plastic surgery literature. Such injuries are often secondary to atherosclerosis of the distal internal pudendal, common penile or proximal cavernosal artery, or locoregional trauma. Various techniques have been described to restore blood flow to the cavernosal body. Methods: In this report, we review 2 cases of penile revascularization for arteriogenic erectile dysfunction at our level 1 trauma center in 2021-2022 completed by the senior author in conjunction with urology. Results: Both patients sustained pelvic crush injuries with resultant arteriogenic impotence minimally responsive to medical management with phosphodiesterase inhibitors and/or injection therapy. After thorough urologic and vascular workup, they underwent microsurgical revascularization of the penis utilizing the deep inferior epigastric arteries with anastomosis to the deep dorsal penile veins. Both patients demonstrated improvement in erectile dysfunction and were able to achieve sustained erection with adequate glans tumescence on minimal pharmacotherapy postoperatively. One patient noted ability to achieve penetration. Patient 1 experienced postoperative retention requiring Foley placement, and both patients experienced glans edema requiring additional urologic procedures (patient 1: dorsal slit, patient 2: completion circumcision). Conclusions: Overall, we have demonstrated improvement of sexual function with the most common complication being prolonged penile edema requiring release of constriction by our urology colleagues. Additional research in the plastic surgery field is warranted to further refine the technique and improve outcomes.

RESUMO

Pyoderma gangrenosum (PG) is a rare disease characterized by ulcerative cutaneous lesions that can occur postoperatively and is often associated with autoimmune disorders. PG is diagnosed by excluding other conditions that can cause ulcerations, such as infections, which may also result in immunosuppressive treatment delays and suboptimal wound care. Operative debridement of wounds has traditionally been avoided in the acute setting secondary to pathergy. This article presents a case of extensive breast PG that was successfully treated with surgical debridement, porcine-derived extracellular matrix, and negative pressure wound therapy while on systemic immunosuppressive therapy.

RESUMO

Background: Medical tourism in plastic surgery has grown exponentially over the last decade. The rise in the number of cases is multifactorial but is mostly driven by reduced cost. While this may seem attractive to patients, it is not without risk. Even under the best circumstances, complications can arise, and patients may be put at increased risk of atypical infections due to different sterilization standards. Lack of customary follow-up and accessibility can lead to delays in diagnosing infections and cause patients to seek care locally. We present our experience in managing atypical infections resulting from cosmetic surgery tourism in a tertiary care system. Methods: We report a case series of 3 patients who underwent cosmetic procedures abroad who presented to our institutions with postoperative complications and infections. Results: Our cohort consist of 3 female patients ranging from 26 to 48 years of age who had cosmetic surgery abroad. All 3 presented with nontuberculous mycobacteria (NTM) infections. Conclusions: Cosmetic surgery tourism is luring patients with advertised all-inclusive surgery and vacation packages at reduced cost. This attracts vulnerable patients and puts them at risk of devastating long-term physical and financial sequalae. NTM infections should be considered early in this population, especially when they are not responding to other therapies. More widespread information about the consequences of traveling for medical procedures is needed to help inform and empower patients to make educated decisions when choosing where to seek care.

RESUMO

Hypergranulation is the abnormal accumulation of granulation tissue in a wound and is commonly seen in burns. It impairs wound healing and can predispose patients to infection. There is no gold standard treatment for hypergranulation tissue, but some options include surgical debridement, chemical cautery with silver nitrate, and topical steroids. Silver nitrate treatment is painful and can lead to scarring, so topical steroid use is on the rise. A retrospective review, between January 1, 2017 and August 30, 2021, at a tertiary burn center was performed to analyze outcomes of hypergranulation tissue after treatment with a topical 50/50 mixture of triamcinolone (Perrigo, Dublin, Ireland) and Polysporin (Johnson & Johnson, New Brunswick, NJ). One hundred and sixteen patients were treated with triamcinolone and Polysporin for hypergranulation tissue, although 24 did not meet inclusion criteria. Eighty-eight out of 92 patients were successfully treated until hypergranulation resolution, while 4/92(4.3%) required silver nitrate or surgery despite the topical cream to achieve resolution. In the 88 patients successfully treated until hypergranulation resolution, 99 areas of hypergranulation were treated. Forty-one of 99 (41.4%) hypergranulation areas resolved within 2 weeks. The average time to hypergranulation resolution was 27.5 ± 2.5 days. We found that a novel 50/50 mixture of triamcinolone and Polysporin topical ointment is an effective and safe treatment for hypergranulation tissue in burn wounds. Further prospective studies are needed to determine its efficacy and safety profile.

RESUMO

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a cyclical, progressive disease that begins at the time of axillary dissection and worsens in the setting of adjuvant oncologic therapies. The paradigm of lymphedema management in these patients is shifting from therapeutic surgeries and decongestive therapy to preventative surgery with immediate lymphatic reconstruction (ILR). METHODS: After institutional review board approval, a prospective database was maintained of all patients undergoing ILR. Patients were excluded if they had preoperative lymphedema or expired during the study period. All ILR were performed by the senior author. A control group was established with standardized physician delivered phone surveys of patients who had axillary dissection for breast cancer (same oncologic surgeon cohort) prior to the implementation of ILR at the same institution. The study and control groups were matched based on history of adjuvant radiation and body mass index. RESULTS: A cohort of patients between 2016 and 2019 with 2 years of follow-up after undergoing ILR (77 patients) were matched with those who did not undergo lymphatic reconstruction (94 patients). The incidence of lymphedema in the study group undergoing ILR was 10% (N = 8). In comparison, the incidence in the cohort who did not undergo lymphatic reconstruction was 38% (N = 36; p < 0.01). Patients with ILR had 92% lower odds of developing lymphedema (p < 0.01). CONCLUSION: ILR can significantly reduce the risk of developing BRCL in high-risk patients at 2 years of follow-up. Patients receiving adjuvant radiation therapy are more likely to develop BCRL after ILR compared with those who do not. Ongoing studies include investigation aimed at identifying patients most at risk for the development of BRCL to help target intervention as well as elucidate factors that contribute to the success of ILR.

RESUMO

INTRODUCTION: Reduction mammaplasties are routinely performed on women of child-bearing age, yet there still exists some uncertainty regarding a patient's ability to breastfeed following the procedure. This is due to inconsistent definitions of "successful" breastfeeding, a variety of pedicles implemented, and inadequate follow-up in the published literature. Our aim was to summarize the current data and provide clear recommendations for counseling patients on expected breastfeeding outcomes following reduction mammaplasty. METHODS: A systematic review and meta-analysis in accordance with the PRISMA guidelines was conducted. We included papers that reported proportion of breastfeeding ability following reduction mammaplasty. RESULTS: We identified 33 papers that met our inclusion criteria. We found that women who undergo reduction mammaplasty are at a 3.5 times increased odds of not being able to breastfeed compared to controls. Overall, reduction mammaplasty patients have a breastfeeding success rate of 62%. The breastfeeding success rate for patients with inferior pedicles was 64%, superior pedicles was 59%, and lateral pedicles was 55%. No conclusions could be drawn regarding medial, central, vertical, and horizontal pedicles on breastfeeding ability. CONCLUSION: Current data suggest that women undergoing reduction mammaplasty have an increased odds of unsuccessful breastfeeding when compared to similar women who have not undergone the procedure. Based on the current literature, pedicle type does play a role in rate of breastfeeding success, although there is a need for further research on the aforementioned pedicles. Physicians should be aware of the likelihood of successful breastfeeding following reduction mammaplasty so that patients can be more thoroughly counseled prior to a decision for surgery.

RESUMO

INTRODUCTION: As medical cost continues to rise, so has the use of medical tourism by patients as a more cost-effective alternative. While the upfront cost savings attract many unsuspecting patients from their country of origin, there are significant patient safety issues surrounding short- and long-term follow-up, as well as the management and cost of complications. METHODS: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses on complications that presented after cosmetic surgeries performed abroad. The literature search was performed on October 18, 2022, using the databases of PubMed, Google Scholar, and Embase. RESULTS: From the 44 studies that were included, 589 patients were identified who presented with complications after having a cosmetic procedure abroad. Infection was the most prevalent complication in this study followed by wound dehiscence, seroma/hematoma, and tissue necrosis. Ninety-eight percent of the infectious organisms were bacterial, and 81% of them were from the Mycobacterium genus. CONCLUSIONS: Cosmetic tourism is a global phenomenon. This systematic review highlights the nature of complications following cosmetic tourism, the surgeries that resulted in complications, the countries that the primary procedures took place in, and the countries of origin of the patients. To aid in reducing morbidity and mortality from cosmetic tourism, regulatory bodies should educate and empower the public to aid them in making educated medical conditions when seeking care.

RESUMO

Measuring skin color for medical research in an objective and nonbiased manner usually requires expensive equipment such as spectrophotometry and requires the subject to be present in person. We present a novel method to measure skin color from photographs using the Skin Analyzer application as a more effective, accessible, and efficient alternative. A desktop application, the Skin Analyzer, was developed to convert skin samples collected from digital images to the L*a*b color space and uses those values to calculate an individual typology angle that correlates to a Fitzpatrick skin type. To assess accuracy in variable lighting, six known colors representing the six Fitzpatrick skin types were printed and photographed in 15 separate locations within the hospital. To account for user variability in sample selection, interrater reliability was calculated with data generated by 13 untrained users testing the app on six subjects. The accuracy of measuring known values, which is the classification accuracy, was calculated to be 80%. Krippendorff alpha test was used to evaluate interrater reliability. The obtained alpha of 0.84 indicates a high interrater reliability. The high accuracy and reliability make the Skin Analyzer a suitable method of objectively determining Fitzpatrick skin type from images. The app may be used to investigate the effects of skin tone in various areas of interest, especially in retrospective studies where skin colorimeters cannot be used.

RESUMO

BACKGROUND: Paraspinal muscle (PSM) flaps can be mobilized with superficial undermining and lateral release from the thoracolumbar fascia and/or deep undermining and medial release from the transverse processes and ribs. The objective of the study was to compare the effect of the PSM flap technique on drain use, retention, and complication rates. METHODS: A retrospective chart review was performed for patients who underwent spinal coverage with PSM flaps at a single institution from April 2020 to June 2021. Patient demographics, preoperative comorbidities, surgical technique, drain usage, and postoperative complications were analyzed to compare the effects of different PSM flap surgical techniques on postoperative drain use and complications. RESULTS: Sixty patients were included. Both superficial and deep releases were performed in half (47%) of the cases, while the remainder was split between superficial (25%) and deep (28%) releases. Drains were used less frequently for the deep release (35%) than the superficial (93%) or both releases (96%, p < 0.01). The deep release had shorter mean drain retention time (5.8 days) than the superficial (30.3 days) or both releases (24.8 days, p < 0.01). There were no significant differences between the techniques in terms of complications. For the deep release, the use of drains was not associated with a reduction in complications (odds ratio 0.91 [0.84 - 0.98], p = 0.97). CONCLUSIONS: In a selected patient population, a "deep release only" PSM flap technique may allow for drainless spinal closure without an increased risk of seroma or other complications.

RESUMO

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a limiting sequelae of breast cancer treatment that may negatively impact 30% to 50% of high-risk breast cancer survivors. Risk factors for development of BCRL include axillary lymph node dissection (ALND), and recently, axillary reverse lymphatic mapping and immediate lymphovenous reconstruction (ILR) at time of ALND have been implemented to prevent BCRL. Reliable anatomy of neighboring venules has been commented on in the literature; however, little information exists about anatomical location of local lymphatic channels amenable for bypass. METHODS: After institutional review board approval, patients who underwent ALND with axillary reverse lymphatic mapping and ILR at a tertiary cancer center from November 2021 to August 2022 were applicable for this study. The location and number of lymphatic channels used for ILR were identified and measured intraoperatively with the arm abducted to 90 degrees and soft tissue under no tension. Four measurements were taken to localize each lymphatic and were based on relationship with reliable anatomic landmarks including 4th rib, anterior axillary line, and lower border of the pectoralis major muscle. Demographics, oncologic treatments, intraoperative factors, and outcomes were prospectively maintained. RESULTS: Twenty-seven patients met inclusion for this study by August 2022 with a total of 86 lymphatic channels identified. Patients were on average 50 ± 12 years old with a body mass index of 30 ± 6 and had an average of 1 vein and 3 identifiable lymphatic channels amenable to bypass. Seventy percent of lymphatic channels were found in a cluster of 2 or more channels. The average horizontal location was 4.5 ± 1.4 cm lateral to the 4th rib. The average vertical location was 1.3 ± 0.9 cm from the superior border of the 4th rib. CONCLUSIONS: These data comment upon intraoperatively identified and consistent location of upper extremity lymphatic channels used for ILR. These lymphatic channels are often found in clusters with 2 or more lymphatic channels at the same location. Such insight may aid in easier intraoperative identification of amenable vessels for the unexperienced surgeon, decrease in intraoperative time, and higher success of ILR.

RESUMO

INTRODUCTION: Breast cancer-related lymphedema (BCRL) is a chronic condition that can negatively affect the quality of life of breast cancer survivors. Immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection is emerging as a technique for the prevention of BCRL. This study compared the incidence of BRCL in patients who received ILR and those who were not amenable to ILR. METHODS: Patients were identified through a prospectively maintained database between 2016 and 2021. Some patients were deemed nonamenable to ILR due to a lack of visualized lymphatics or anatomic variability (eg, spatial relationships or size discrepancies). Descriptive statistics, independent t test, and Pearson χ 2 test were used. Multivariable logistic regression models were created to assess the association between lymphedema and ILR. A loose age-matched subsample was created for subanalysis. RESULTS: Two hundred eighty-one patients were included in this study (252 patients who underwent ILR and 29 patients who did not). The patients had a mean age of 53 ± 12 years and body mass index of 28.6 ± 6.8 kg/m 2 . The incidence of developing lymphedema in patients with ILR was 4.8% compared with 24.1% in patients who underwent attempted ILR without lymphatic reconstruction ( P = 0.001). Patients who did not undergo ILR had significantly higher odds of developing lymphedema compared with those who had ILR (odds ratio, 10.7 [3.2-36.3], P < 0.001; matched OR, 14.2 [2.6-77.9], P < 0.001). CONCLUSIONS: Our study showed that ILR was associated with lower rates of BCRL. Further studies are needed to determine which factors place patients at highest risk of developing BCRL.

RESUMO

ABSTRACT: Autologous fat grafting is a technique that can be used for cosmetic and reconstructive indications such as oncologic defects, aging, trauma, and congenital malformations. However, there is no standardized technique, and one of the main challenges is the unpredictable rate of fat resorption. When using fat grafting, it is crucial to understand the different factors that contribute to adipocyte viability. A literature search, using PubMed, was conducted in 2022 with variations of the terms "autologous fat grafting," "fat harvesting," "fat processing," and "fat injection." Articles in the English language that presented original data about different factors that may affect adipocyte viability for fat grafting were included in this review. Syringe suction harvests (lower pressures), compared with other methods with higher pressures, were found to have increased adipocyte counts and viability, but this did not translate clinically during in vivo studies. The studies have shown that, despite our efforts in optimizing fat harvest, processing, and injection, no statistical or clinical differences have been found. Additional studies are still needed to determine a universal protocol for optimal fat graft survival.

RESUMO

BACKGROUND: The palmar aponeurosis or "A0 pulley" may play a role in trigger finger pathology. This study assesses the involvement of the A0 pulley in patients receiving trigger finger release. METHODS: This single-surgeon, prospective, randomized clinical trial was conducted among consenting patients with symptomatic trigger finger. Intraoperative coin toss was used to randomize initial release of either the A0 or A1 pulley. Following release, active flexion and extension of the affected digit were examined. The remaining pulley was then released in sequence, and clinical trigger status was recorded. RESULTS: Thirty fingers from 24 patients were released; 17 fingers received A0 release first, and 13 received A1 release. Following initial A0 release, 8 fingers (47%) demonstrated complete resolution of symptoms, 4 (24%) demonstrated improvement but incomplete resolution of triggering, and 5 (29.4%) demonstrated no improvement. Following initial A1 release, 6 fingers (46%) demonstrated complete resolution, 3 (23%) demonstrated improvement but incomplete resolution of triggering, and 4 (31%) demonstrated no improvement. All patients demonstrated complete resolution after surgical release of both sites. Neither initial A1 release nor initial A0 release was statistically associated with complete, incomplete, or failed symptom resolution. CONCLUSIONS: These data implicate the A0 pulley as the primary cause of 31% to 47% of trigger fingers in our study. Although larger trials are needed to validate these results, our study suggests that release of both A0 and A1 pulleys may offer greater symptom resolution than release of the A1 pulley alone.

RESUMO

Tendons and bones comprise a special interacting unit where mechanical, biochemical, and metabolic interplays are continuously in effect. Bone loss in osteoporosis (OPo) and its earlier stage disease, osteopenia (OPe), may be coupled with a reduction in tendon quality. Noninvasive means for quantitatively evaluating tendon quality during disease progression may be critically important for the improvement of characterization and treatment optimization in patients with bone mineral density disorders. Though clinical magnetic resonance imaging (MRI) sequences are not typically capable of directly visualizing tendons, ultrashort echo time MRI (UTE-MRI) is able to acquire a high signal from tendons. Magnetization transfer (MT) modeling combined with UTE-MRI (i.e., UTE-MT-modeling) can indirectly assess macromolecular proton content in tendons. This study aimed to determine whether UTE-MT-modeling could detect differences in tendon quality across a spectrum of bone health. The lower legs of 14 OPe (72 ± 6 years) and 31 OPo (73 ± 6 years) female patients, as well as 30 female participants with normal bone (Normal-Bone, 36 ± 19 years), are imaged using UTE sequences on a 3T MRI scanner. Institutional review board approval is obtained for the study, and all recruited subjects provided written informed consent. A T1 measurement and UTE-MT-modeling are performed on the anterior tibialis tendon (ATT), posterior tibialis tendon (PTT), and the proximal Achilles tendon (PAT) of all subjects. The macromolecular fraction (MMF) is estimated as the main measure from UTE-MT-modeling. The mean MMF in all the investigated tendons was significantly lower in OPo patients compared with the Normal-Bone cohort (mean difference of 24.2%, p < 0.01), with the largest Normal-Bone vs. OPo difference observed in the ATT (mean difference of 32.1%, p < 0.01). Average MMF values of all the studied tendons are significantly lower in the OPo cohort compared with the OPe cohort (mean difference 16.8%, p = 0.02). Only the PPT shows significantly higher T1 values in OPo patients compared with the Normal-Bone cohort (mean difference 17.6%, p < 0.01). Considering the differences between OPo and OPe groups with similar age ranges, tendon deterioration associated with declining bone health was found to be larger than a priori detected differences caused purely by aging, highlighting UTE-MT MRI techniques as useful methods in assessing tendon quality over the course of progressive bone weakening.

RESUMO

BACKGROUND: We sought to compare the safety profile of prepectoral breast reconstruction with total submuscular tissue expander reconstruction, previously our standard. Primary outcomes of interest in this retrospective cohort study were incidence of infection, hematoma, seroma, mastectomy flap necrosis, and reconstruction loss. METHODS: Total submuscular and prepectoral with acellular dermal matrix reconstructions consecutively performed by a single surgeon (P.D.S.) between January 1, 2016, and December 31, 2019, were compared. Demographic and clinical characteristics, as well as complications and complication types, were extracted for all patients. A t test was used to assess differences in continuous variables. Multivariate logistics regression was used to assess the association between type of reconstruction and complication rate. The statistical significance was set at 0.05 for all comparisons. RESULTS: A total of 133 patients (234 breasts) were included. There was a significantly greater incidence of infection (16.5% vs 5.5%, P < 0.01) in the prepectoral/acellular dermal matrix cohort. However, reconstructive loss was low in both cohorts (2.5% and 3.0%, P = 0.83). Adjusted odds ratio for complications in the prepectoral cohort was 2.26, but this was not statistically significant (adjusted P = 0.24). CONCLUSIONS: Prepectoral breast reconstruction shares an overall complication profile that is not greater than that of total submuscular reconstruction. It is associated with a greater risk of infection; however, the ability to salvage the reconstruction with early, aggressive intervention results in low rates of reconstructive loss, comparable with those of total submuscular reconstruction.

RESUMO

BACKGROUND: Breast cancer-related lymphedema is a progressive disease that poses tremendous physical, psychosocial, and financial burden on patients. Immediate lymphaticovenular anastomosis at the time of axillary lymph node dissection is emerging as a potential therapeutic paradigm to decrease the incidence of breast cancer-related lymphedema in high-risk patients. METHODS: Eighty-one consecutive patients underwent reverse lymphatic mapping and, when feasible, supermicrosurgical immediate lymphaticovenular anastomosis at the time of axillary lymph node dissection at a tertiary care cancer center. Patients were followed prospectively in a multidisciplinary lymphedema clinic (plastic surgery, certified lymphatic therapy, dietary, case management) at 3-month intervals with clinical examination, circumferential limb girth measurements, and bioimpedance spectroscopy. An institutional control cohort was assessed for the presence of objectively diagnosed and treated breast cancer-related lymphedema. Data were analyzed by a university statistician. RESULTS: Seventy-eight patients met inclusion, and 66 underwent immediate lymphaticovenular anastomosis. Mean follow-up was 250 days. When compared to a retrospective control group, the rate of lymphedema in patients who underwent immediate lymphaticovenular anastomosis was significantly lower (6 percent versus 44 percent; p < 0.0001). Patients with 6-month follow-up treated with combined adjuvant radiation therapy and chemotherapy had significantly greater risk of developing breast cancer-related lymphedema (p = 0.04) compared to those without combined adjuvant therapy. Arborized anastomotic technique had a statistically shorter operative time than end-to-end anastomosis (p = 0.005). CONCLUSIONS: This series of consecutive patients demonstrate a 6 percent incidence of early-onset breast cancer-related lymphedema with immediate lymphaticovenular anastomosis and an increased risk in those undergoing combined adjuvant treatment. These early data represent an encouraging and substantial decrease of breast cancer-related lymphedema in high-risk patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
