Improving outcomes in autologous breast reconstruction

Abstract

Autologous breast reconstruction can often provide a more aesthetic outcome than other options for breast reconstruction because breast volume and shape can be extensively modified based on individual need, the texture of the reconstructed breast is a closer match to the native breast, and complications such as capsular contracture are avoided. However, with these benefits come the potential for complications unique to autologous tissue transfer. While overall complications are low, there are ways to maximize operative success and minimize the risk of complications. Deep inferior epigastric artery perforator (DIEP) flaps, the current mainstay in choice of autologous reconstruction, provide generally good outcomes. However, improvements in outcomes can still be achieved with a better understanding of individual anatomy. Perforator size, location, intramuscular and subcutaneous course, and association with motor nerves are all factors that can significantly affect operative technique, length of operation, and operative outcomes. With significant variation between individuals, preoperative imaging has become an essential element of DIEP flap surgery. Computed tomography angiography (CTA) is currently the gold standard but evolving techniques such as magnetic resonance angiography (MRA) and image-guided stereotaxy are rapidly contributing to improved outcomes.
