Bipedicled DIEAP flaps for reconstruction of limb soft tissue defects in male patients

SummaryBackgroundExtensive soft tissue deficiencies involving the limbs can be difficult to reconstruct and may require more than one microsurgical flap transfer to cover the defect. This can be particularly challenging in male patients, where the sacrifice of a donor muscle could result in considerable comorbidity. This paper describes the use of the bipedicled deep inferior epigastric artery perforator (DIEAP) flap to perform a one-stage reconstruction of extensive soft tissue defects in male patients.MethodsBy using preoperative multidetector computed tomographic (MDCT) angiography, the dominant perforators of the abdominal wall were identified and the bipedicled DIEAP flap was used for a one-stage reconstruction of complicated tissue loss in 12 male patients. In seven of these flaps, a microsurgical anastomosis between the two epigastric pedicles of the DIEAP flap was carried out. The feasibility of the procedure, clinical outcome, and possible associated comorbidities were evaluated.ResultsSuccessful large tissue reconstructions were performed using all four traditional zones of the DIEAP flap, with dimensions of flaps ranging from 20 × 8 to 50 × 17 cm. Venous congestion was seen to develop in two flaps, one of which was salvaged by performing an additional venous anastomosis, but the other flap failed to survive. Apart from this, complications were minimal.ConclusionsSoft tissue coverage of extensive wounds in male patients without sacrificing muscle flaps can be challenging. This extended utilization of the entire DIEAP flap has helped us to address this issue.
