Arterialized venous flap is useful for reconstruction of the traumatic soft tissue defect in fingers, but insufficient circulation of the traumatic fingers makes surgeons annoying to use the flap. We have grafted flaps in 7 fingers with insufficient vascular bed hoping to expanded the category of the flap. MATERIALS AND METHODS: Arterialized venous flap have transplanted in 7 fingers from March 2008 through February 2010 and followed up for 4 to 16 months(average 7.2 months). They were all male with a mean age at the time of surgery was 33. The main injury was crushing in 4 degloving, contact burn and saw injury was I respectively. Time interval from injury to flap transplantation was average 3.1. weeks(3 days to 6 weeks). Designed flap size ranges from 8 cm x 3.5 cm to 4 cm x 3 cm. Vessel type of flap was one artery with two veins were 5 cases and one artey with one vein 2. Flap type was cutaneous in 3, tendocutaneous 2, neurotendocutaneous 1 and neurocutaneous 1. The circulation state of recipient site was avascular in 2 cases, insufficiency 3 and tip avascular 2.

Arterialized venous flap was complete survived in 2 cases, partial necrosis(less than 10%) 3 and failed in 2.

An arterialized venous free flap could be a useful procedure for reconstruction in soft tissue or combined defect of the finger despite an avascular or insufficient vascular beds if the recipient beds were free from infection.
