Microsurgical anatomy of the lateral skin flap of the leg.

The blood supply, venous drainage, and innervation of the lateral skin flap of the leg were studied in 52 fresh specimens by dissection, angiography, and selected injection of cutaneous arteries with india ink. This flap has a long vascular pedicle that contains the peroneal artery and vein and their branches. The diameter of the peroneal artery is about 3.7 mm. There are 4 to 7 cutaneous branches that penetrate the posterior intermuscular septum and widely anastomose with each other in the subcutaneous tissue. The skin area supplied by the peroneal artery measures approximately 32 X 15 cm. There are 2 sets of veins in the flap: (1) 2 deep veins, the peroneal veins, are about 4 mm in diameter, and (2) a superficial vein, the small saphenous vein, is about 3.3 mm in diameter. The cutaneous nerve is the lateral sural cutaneous nerve. This new lateral skin flap of the leg may be used either as a free flap or as a cutaneous flap and has been proven successful clinically.

Lateral lower leg skin flap.

Use of a lower leg lateral skin flap in 7 patients since January 1982 is described. Satisfactory results were obtained in 6 of 7 patients. The blood supply of this new flap is based on the peroneal artery, which gives rise to cutaneous or musculocutaneous branches to nourish the flap. The venous blood of the flap is drained by the venae comites accompanying these cutaneous or musculocutaneous branches. In clinical practice, the beginning portion of the peroneal artery and the vein arising from the posterior tibial vein are used for vascular anastomosis. The caliber of the peroneal artery is 2.5 to 3.0 mm, and that of the peroneal vein is 3 to 4 mm. The vascular pedicle can be as long as 8 to 12 cm. In 4 of these patients, the flaps were freely transferred using a microvascular technique; in the remaining 3, a reversed transfer for treating defects over the foot was used.

Arterialized venous free sural nerve grafting.

Since August 1980, a new technique of nerve grafting has been developed in our clinic. A free sural nerve graft, with its attached small saphenous vein arterialized, was used for repairing long segments of nerve defects. Experimental studies of this kind of nerve graft have proved the merits of this new technique. The same favorable results were then obtained in 14 patients, with 2 grafts failing because of vascular thrombosis. We have the impression that the shorter the time interval between the injury and the surgical repair, the better the result. In 2 patients with motor nerve injury, the motor function was well recovered when the operation was performed within 6 months after the injury, whereas none was recovered in those cases with an interval longer than 2 years.
