BackgroundPerforator flaps minimize abdominal site morbidity during autologous breast reconstruction. The purpose of this study was to assess whether the number of perforators harvested influences the overall deep inferior epigastric perforator (DIEP) flap survival and flap-related complications.MethodsA retrospective review was performed of all DIEP flaps performed at the Hospital of the University of Pennsylvania from 2006 to 2011. The outcomes assessed included flap loss and major complications. We compared flaps by the number of total perforators (1-4) and then carried out a subgroup analysis comparing flaps with one perforator to flaps with multiple perforators. Lastly, we conducted a post-hoc analysis based on body mass index (BMI) categorization.ResultsThree hundred thirty-three patients underwent 395 DIEP flaps. No significant differences were noted in the flap loss rate or the overall complications across perforator groups. However, the subgroup analysis revealed significantly higher rates of fat necrosis in the case of one-perforator flaps than in the case of multiple-perforator flaps (10.2% vs. 3.1%, P=0.009). The post-hoc analysis revealed a significant increase in the flap loss rate with increasing BMI (<30=2.0%, 30-34.9=3.1%, 35-39.9=3.1%, >40=42.9%, P<0.001) in the DIEP flaps, but no increase in fat necrosis.ConclusionsThis study demonstrates that the number of perforators does not impact the rate of flap survival. However, the rate of fat necrosis may be significantly higher in DIEP flaps based on a single perforator. Multiple perforators should be utilized if possible to decrease the risk of fat necrosis.
Women receive breast implants for both aesthetic and reconstructive reasons. This brief review discusses the evolution of and complications related to breast implants, as well as key considerations with regard to aesthetic and reconstructive surgery of the breast. KEY POINTSNearly 300,000 breast augmentation surgeries are performed annually, making this the second most common aesthetic procedure in US women (after liposuction).Today, silicone gel implants dominate the world market, and in the United States, approximately 60% of implants contain silicone gel fi ller.Capsular contracture is the most common complication of breast augmentation, typically presenting within the fi rst postoperative year and with increasing risk over time. It occurs with both silicone and saline breast implants.Numerous studies have demonstrated the safety of silicone breast implants with regard to autoimmune disease incidence. However, the risk of associated anaplastic large-cell lymphoma must be discussed at every consultation, and confi rmed cases should be reported to a national registry.
Autologous pedicled tissue was slightly more cost-effective than free tissue reconstruction in irradiated and nonirradiated patients. Implant-based techniques were not cost-effective. This is in agreement with the growing trend at academic institutions to encourage autologous tissue reconstruction because of its natural recreation of the breast contour, suppleness, and resiliency in the setting of irradiated recipient beds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
