The effect of sarcopenia on perioperative complications in abdominally based free-flap breast reconstruction.

PURPOSE: The identification of patient-specific risk factors, which predict morbidity following abdominally based microvascular breast reconstruction is difficult. Sarcopenia is a proxy for patient frailty and is an independent predictor of complications in a myriad of surgical disciplines. We predict that sarcopenic patients will be at higher risk for surgical complications following abdominally based microvascular breast reconstruction. METHODS: A retrospective study of all patients who underwent delayed abdominally based autologous breast reconstruction following postmastectomy radiation therapy from 2007 to 2013 at a single institution was conducted. Univariate and multiple logistic regression models were used to assess the effect of sarcopenia on postoperative outcomes. RESULTS: Two hundred and eight patients met the inclusion criteria, of which 30 met criteria for sarcopenia (14.1%). There were no significant differences in demographics between groups. There were no significant differences in minor (36.7% vs 44.4%; P = .43) or major (16.7% vs 25.3%; P = .36) complications between groups as well as hospital length of stay. Multivariable logistic regression demonstrated that a staged reconstruction with the use of a tissue expander was the only consistent variable, which predicted major complications (OR, 2.24; 95% CI, 1.18-4.64; P = .015). CONCLUSIONS: Sarcopenia does not predispose to minor or major surgical complications in patients who undergo abdominally based microsurgical breast reconstruction.

Breast Implant Imaging Surveillance among U.S. Plastic Surgeons: U.S. Food and Drug Administration Recommendations versus Clinical Reality.

BACKGROUND: Device rupture is considered a major complication associated with breast implants. The U.S. Food and Drug Administration recommends magnetic resonance imaging (MRI) surveillance 3 years after implantation and then every 2 years, but adherence to these recommendations is poor. The authors identified current practice management for breast implant rupture surveillance by surveying practicing U.S. plastic surgeons. METHODS: An online survey of all active members of the American Society of Plastic Surgeons was performed. Questions analyzed imaging practice patterns related to breast implants. Logistic regression models were used to analyze determinants for radiographic imaging in breast implant patients. RESULTS: The survey had a response rate of 16.5 percent. For patients with breast implants, 37.7 percent of respondents recommended MRI at the recommended intervals. Fifty-five percent perform imaging only if there is a problem with the implant. Academic surgeons more frequently recommended MRI (56.3 percent and 39.3 percent; p = 0.0002). Surgeons with less than 5 years of experience are four times more likely to order MRI than surgeons with over 25 years' experience (60.8 percent and 28.1 percent; p < 0.0001). Furthermore, lower volume surgeons recommend significantly more MRI (45.2 percent and 27.3 percent; p = 0.001). Respondents are almost two times more likely to recommend MRI in reconstructive versus cosmetic patients (51.2 percent and 35.6 percent; p = 0.0004). CONCLUSIONS: MRI limitations include high costs, time commitments, and equipment constraints. Fewer than 40 percent of survey respondents suggest the recommended screening frequency to their patients; however, academic, low-volume, early-career surgeons are more likely to recommend MRI implant monitoring. Screening recommendations need to be evidence based and align with common practices to prevent undue system, provider, and patient burden.

Perforator Mapping of the Profunda Artery Perforator Flap: Anatomy and Clinical Experience.

BACKGROUND: Discovering alternatives to workhorse flaps that have more consistent anatomy and lower donor-site morbidity has become a focus of reconstructive surgery research. This study provides a simplified approach to profunda artery perforator flap design and harvest based on reliable anatomical landmarks. METHODS: A retrospective review was conducted of 70 patients who underwent 83 profunda artery perforator flap reconstructions for postoncologic defects from 2016 to 2018. The authors recorded and analyzed the profunda artery perforator flap sizes and clinical applications, the numbers and locations of the perforators, and the patient outcomes. RESULTS: Most of the profunda artery perforator flaps were for head and neck [46 patients (65.7 percent)] and breast [21 patients (30 percent)] reconstructions. Flaps were most commonly based on perforator A (33.7 percent) and perforator B (33.7 percent), followed by perforators B and C combined (18.1 percent). Perforators were located a mean of 7.5 cm (perforator A), 12.7 cm (B), and 17.6 cm (C) distal to the pubic tubercle parallel to the axis between the pubic tubercle and the medial femoral condyle and 7.9 cm (A), 7.3 cm (B), and 6.1 cm (C) posterior from the axis. There was no flap loss. One patient underwent successful salvage surgery after arterial flap thrombosis. Eight patients (9.6 percent) developed superficial wound dehiscence that was managed conservatively. CONCLUSIONS: Perforator mapping demonstrated consistent anatomical locations of sizeable profunda artery perforators in the inner thigh. Along with its consistent and robust vascular anatomy and minimal donor-site morbidity, the profunda artery perforator flap's volume and pliability make it a reliable option for soft-tissue reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
