  Postoperative fat necrosis was analyzed using ultrasonography. RESULTS Ninety-four patients were analyzed. Mean maximal contralateral perfusion length was as follows grade 0, 7.50 ± 1.89 cm; grade 1, 7.93 ± 2.01 cm; and grade 2, 10.14 ± 2.29 cm. Grade 2 had a statistically significantly greater contralateral perfusion length than grade 0 (p less then 0.001) and grade 1 (p less then 0.001). Fat necrosis occurred in 27.3 percent (grade 0), 19.1 percent (grade 1), and 8 percent (grade 2), which was statistically significant (p = 0.035). CONCLUSIONS A definite vessel connection across the midline (as in grade 2) in preoperative computed tomographic angiography indicates that contralateral perfusion will be sufficiently achieved. This vessel scoring system would be helpful in predicting flap perfusion and planning the surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE Diagnostic, IV.BACKGROUND Studies have cited possible complications and increased fluid accumulation in implant-based breast reconstruction using acellular dermal matrix. The authors propose a novel approach, manually meshing acellular dermal matrix using a skin graft mesher before use in expander-based breast reconstruction. The authors investigated postoperative drain time, complication rates, pain, and length of hospital stay in meshed versus unmeshed acellular dermal matrix cohorts. METHODS One hundred fourteen patients and 194 reconstructed breasts were included overall. Of these, 99 patients were included in the pain and postoperative length of hospital stay analysis.  https://www.selleckchem.com/Bcl-2.html  Independent t test and chi-square analyses were used for bivariate comparisons. Multiple linear regression analyses were used to further delineate impact of meshing acellular dermal matrix on drain time, postoperative parenteral narcotic requirements, and length of stay between the two cohorts. RESULTS The meshed acellular dermal matrix cohort had lower overall complication rates compared with the unmeshed cohort. Multiple linear regression analyses showed meshing the acellular dermal matrix alone decreased drain time by 7.3 days, and decreased postoperative parenteral narcotic requirements by 77 percent (20 mg morphine). Furthermore, it was the only significant predictor for a decrease in length of stay. CONCLUSIONS Meshing acellular dermal matrix significantly decreased the time needed for postoperative drains.  https://www.selleckchem.com/Bcl-2.html  Statistical analysis showed significantly decreased overall and minor complication rates in the meshed cohort. Meshing significantly decreased parenteral narcotic requirements and, importantly, also decreased length of stay. All of these factors have important implications regarding cost and quality of care in expander-based breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.BACKGROUND The resurgence of prepectoral breast reconstruction has brought strict patient inclusion and exclusion criteria by numerous authors. This article provides an overview of a single surgeon's experience with 201 patients, 313 breasts using immediate, direct-to-implant prepectoral breast reconstruction. The article compares surgical outcomes of different patient cohorts to elucidate risk factors that may predispose patients toward developing complications. METHODS A retrospective chart review was performed, identifying all patients who underwent prepectoral, direct-to-implant breast reconstruction from June of 2016 to June of 2018. RESULTS A total of 201 patients representing 313 breasts were included. A midlateral incision was used in 157 breasts (50.2 percent), followed by a skin-reducing, Wise-pattern in 90 breasts (28.8 percent). Acellular dermal matrix was used in 243 breasts (77.6 percent), free nipple grafts were used in 39 breasts (12.5 percent), and postmastectomy radiation therapy was used in 58 breasts (18.5 percent). Complications requiring operative intervention occurred in 24 breasts (7.7 percent), and minor complications occurred in 23 breasts (7.3 percent). There were no significant differences in complication rates for (1) acellular dermal matrix use versus non-acellular dermal matrix use, (2) Wise-pattern versus other incision, or (3) postmastectomy radiotherapy (p > 0.05). CONCLUSIONS This represents the largest single-surgeon, direct-to-implant prepectoral cohort in the literature. Surgical complications did not differ with acellular dermal matrix use, incision selection, and the use of postmastectomy radiation therapy. There may be an association between acellular dermal matrix use and major complications and radiotherapy with minor complications. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.BACKGROUND The authors present their stacked flap breast reconstruction experience to facilitate selection of either caudal internal mammary vessels or intraflap vessels for the second recipient anastomosis. METHODS A retrospective review was conducted of multiflap breast reconstructions (double-pedicled deep inferior epigastric perforator, stacked profunda artery perforator, and stacked profunda artery perforator/deep inferior epigastric perforator) performed at the authors' institution from 2011 to 2018. Data collected included demographics, recipient vessels used, and intraoperative/postoperative flap complications. Complications were compared between cranial, caudal, and intraflap anastomoses. RESULTS Four hundred stacked flaps were performed in 153 patients. Of 400 arterial anastomoses, 200 (50 percent) were to cranial internal mammary vessels, 141 (35.3 percent) were to caudal internal mammary vessels, and 59 (14.8 percent) were to intraflap vessels. Of 435 venous anastomoses, 145 (33.3 percent) were toflap reconstructions. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.BACKGROUND Patients with breast cancer-related lymphedema can be treated with a simultaneous deep inferior epigastric perforator (DIEP) flap, vascularized inguinal lymph node transfer, and lymphovenous anastomosis for aesthetic breast reconstruction and lymphedema in one operation. METHODS The authors performed a comparison of prospectively followed patients who underwent free flap breast reconstruction with vascularized inguinal lymph node transfer and anastomosis to a retrospective cohort of patients who underwent free flap breast reconstruction with vascularized inguinal lymph node transfer alone. RESULTS Thirty-three patients underwent DIEP flap reconstruction with vascularized inguinal lymph node transfer and lymphovenous anastomosis, and 21 received a free flap with lymph node transfer alone. There were no significant differences in demographics, adjuvant chemotherapy, or radiation therapy. The average number of nodes removed was also equivalent (21.2 versus 21.4 nodes). Two anastomoses per patient, on average, were performed (range, one to four) in the combined cohort, and all patients (100 percent) reported a subjective improvement in symptoms, compared with 81.
