title: Measures to prevent complications of distally based neurovascular sural flaps.
abstract: Several publications in recent years have proven unbroken popularity of superficial sural artery flaps for the coverage of defects of the lower leg and proximal foot. However, complications are being discussed rarely. The realistic complication rate is up to 59%, given corresponding comorbidities, risk factors, or performance errors. Twelve distally based neurovascular sural flaps were used for reconstruction of heel, ankle, and lower-leg defects between 2003 and 2005. The following pre- and postoperative procedures were performed as a routine: An additional arteriography was done preoperatively to prove the patency of the peroneal artery. Acoustic Doppler ultrasound was used to identify the lesser saphenous vein and the concomitant vessels (perforators of the peroneal artery) of the sural nerve. An enlarged skin paddle with a tail of skin over the pedicle at the point of rotation was harvested intraoperatively to take pressure off the vessels and facilitate primary closure. Postoperatively, external fixation provides strict immobilization of the affected leg. Following these measures, no flap loss was observed in the presented series, and only few minor complications occurred.
