Objectives/Interrogation: To evaluate the clinical curative effect of the type I venous flap transplantation of volar forearm for complicated digital replantation.
Methods: From May 2009 to June 2016, 8 cases with 12 fingers who underwent digital replantation using type I venous flap of volar forearm for flow-through dorsal veins of finger and covering soft tissue defects, 5 cases were male, 3 female; age 22 to 58 years (mean age 34.3 years) of follow-up observation, observing the postoperative changes of blood supply of the venous flaps and digital replantation. The process of flap survival and contracture of survived flaps.
Results and Conclusions: 8 cases with 12 fingers of replantation were survived without venous crisis, but 2 cases with 3 fingers had arterial crisis. The color of the all venous flaps were reddish with capillary reflux slowly in 1 day after operation. Then superficial skin exfoliating and formatting blisters. Eventually the wound of flaps healing and the flaps survived completely with an average of 28.5 days after surgery (18-36 d). No venous reflux disorder, swelling and congestion of the flaps during the healing procedure. Flap survived without obvious contracture and did not affect the joint flexion.
The type I venous flap of volar forearm can simultaneously flow-through the dorsal veins of fingers and repair the wound. It is suitable for finger replantation with soft tissue defect of the dorsum of fingers and hand.
