ABSTRACT
A modified, two-stage arteriovenous flow-through venous flap was designed to repair
skin defects due to third-degree burns on the dorsum of the hand in four patients.
Two weeks after plasty of an arteriovenous (A-V) shunt between the greater saphenous
vein and dorsalis pedis artery, the arterialized flow-through venous flap was transferred
using the greater saphenous vein as the pedicle. The size of the flaps utilized ranged
from 7 × 13 cm to 9 × 13 cm. In three patients the entire flap survived without complication.
In one patient whose flap had only one drainage vein, the flap survived with superficial
necrosis of about 10 percent of the flap at the borders. During the 2 weeks after
A-V shunt creation, the authors believe that microcirculation around the arterialized
vein probably develops, contributing to better irrigation and thereby to flap survival.
Using this two-stage procedure, it might be feasible to obtain larger grafts and to
attain a higher flap survival rate.
