title: Venous flap--its classification and clinical applications.
abstract: We previously reported pedicled venous flap survival using the rat model, as well as venovenous, arteriovenous, and arterialized flow-through venous flap survival using the rabbit ear model. For this study, we utilized these flaps clinically. Five of seven pedicled venous flaps survived, displaying superficial necrosis. The others became partially necrotic; they were transferred after dissection of a long pedicle vein. Eight of nine venovenous flow-through venous flaps survived; six displayed superficial necrosis. The nonsurviving flap became completely necrotic, possibly because only one donor vein and one recipient vein were used. Six of 10 arteriovenous flow-through venous flaps survived. The remaining four became partially necrotic, possibly because only one vein was anastomosed for outflow. The arterialized flow-through venous flap survived. The pedicled venous and venovenous groups studied seem likely to survive despite superficial necrosis. However, the draining vein should not be dissected more than 5 cm, and many draining veins should be anastomosed with recipient vessels.
