Frailty lacks a universal definition. The modified Frailty Index (mFI) using patient comorbidities can be used to measure frailty. We hypothesized that mFI predicts 30-day complications after microsurgical breast reconstruction. American College of Surgeons' (ACS) National Surgical Quality Improvement Project (NSQIP) was investigated to identify patients undergoing microsurgical breast reconstruction between 2005-2014 using Current Procedure Terminology (CPT) code, 19364. We used mFI as a measure of frailty. The patients were assigned a frailty score based on the number of preoperative comorbid conditions as defined by the mFI. Other risk indices used include age, BMI, wound class, ASA class. Stratification was performed in ascending order for each. The outcome measure was aggregate 30-day complications. Regression analysis was performed followed by Receptor Operating Characteristic (ROC) curve to determine the accuracy of each risk index in predicting 30-day complications. Of the 3237 patients 24% experienced complications. Univariate logistic regression analysis found odds ratio of complications for frailty score 1 ¼ 22.1 (CI ¼ 17.9-27.3, p < 0.01), and 2 ¼ 28 (CI ¼ 18.3-43, p < 0.01) compared to frailty score ¼ 0. ROC curve demonstrated mFI with the highest concordance score (c-score ¼ 0.816). Multivariable logistic regression found frailty as the strongest independent predictor of 30-day aggregate complications adjusted OR ¼ 22.24, CI ¼ 17.77-27.82, p < 0.01 when compared to other risk indices. The modified Frailty Index is a simple, reliable, and objective tool that can be used to predict postoperative complications after microsurgical breast reconstruction. The application of this tool can help microsurgeons preoperatively identify patients who are at high risk.

Objective To identify the incidence and risk factors for 30-day postoperative mortality after microsurgical head and neck reconstruction following oncological resection. Study Design Retrospective case-control study. Setting American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Methods Microsurgical head and neck reconstructive cases were identified from 2005 to 2018 using Current Procedural Terminology codes and oncologic procedures using the International Classification of Disease 9 and 10 codes. The outcome of interest was 30-day mortality. Results The 30-day postoperative mortality rate was 1.2%. Univariate logistic regression analysis identified the following associations: age >80 years, hypertension, poor functional status, preoperative wound infection, renal insufficiency, malnutrition, anemia, and prolonged operating time. Multivariable logistic regression models were used to stratify further by the degree of malnutrition and anemia. Hematocrit <30% was found to be an independent risk factor for 30-day postoperative mortality (odds ratio [OR] = 9.59, confidence interval [CI] 2.32-39.65, P < .1) with albumin <3.5 g/dL. This association was even stronger with albumin <2.5 g/dL (OR = 11.64, CI 3.06-44.25, P < .01). One-third of patients (36.6%) had preoperative anemia, of which less than 1% required preoperative transfusion, although one-quarter (24.6%) required intraoperative or 72 hours postoperative transfusion. Conclusions Preoperative anemia is a risk factor for 30-day postoperative mortality. This association seems to get stronger with worsening anemia. Identification and optimization of such patients preoperatively may mitigate the incidence of 30-day postoperative mortality.
Background: Diffuse venous malformations that involve all tissues in the upper limb and ipsilateral chest wall are known as “phlebectasia of Bockenheimer.” The authors describe their experience with management of this uncommon vascular anomaly. Methods: The authors’ Vascular Anomalies Center registry comprised 18,766 patients over a 40-year period. This review identified 2036 patients with venous malformations of the extremities (10.8 percent), of whom only 80 (0.43 percent) had Bockenheimer disease. The authors retrospectively analyzed patient characteristics, diagnostics, treatments, and complications. Results: The venous malformation was first noted at birth or within the first few years of life with slow and gradual progression. Pain was related to engorgement of the limb. Thromboses and phleboliths were common, but diffuse intravascular coagulopathy occurred in only 12 patients (15 percent). Skeletal involvement was demonstrated as lytic lesions, cortical scalloping, osteopenia, and pathologic fractures. Management included compression garments (100 percent), sclerotherapy (27.5 percent), and resection of symptomatic areas in 35 percent of patients. Adjunctive pharmacologic medication was given in 7.5 percent. Following resection, 17 patients (60 percent) had one or more complications: hematoma, wound dehiscence, flap loss, contracture, and psychosis. There were no deaths. Symptoms improved in all patients with useful functional outcomes. Conclusions: The decision to pursue compression, sclerotherapy, pharmacologic treatment, or resection alone or in combination was made by an interdisciplinary team. Although extensive venous malformations cannot be completely ablated, debulking of symptomatic regions, resection of neuromas, and noninvasive treatments improve the quality of life. Despite the bulk and weight of the arm, forearm, and hand, and the ominous appearance on magnetic resonance imaging, these patients remain functional. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.
