A retrospective investigation of abdominal visceral fat, body mass index (BMI), and active smoking as risk factors for donor site wound healing complications after free DIEP flap breast reconstructions.

The deep inferior epigastric artery perforator (DIEP) flap is one of the most common techniques for breast reconstruction. Body Mass Index (BMI) is considered an important predictor of donorsite healing complications such as wound dehiscence. The use of computed tomography (CT) techniques has shown a more precise and objective method to assess visceral adipose tissue. It remains unclear whether quantified visceral fat results in more accurate predictions of abdominal wound healing complications than BMI.
