Abstract:
To investigate the effect of venous super drainage applying in free flaps. Methods From June, 2017 to December, 2018, 7 cases who had severe soft tissue injuries were treated with free flap. Cause of injury: 1 electric injuries, 2 tumor-related wounds, 1 deep burns, 2 mechanical trauma, and 1 necrotizing fasciitis. All patients were underwent free flap transplantation. There were 5 cases of anterolateral thigh artery perforator flap, 1 case of superficial circumflex iliac artery perforator flap, and 1 case of first dorsal metatarsal artery perforator flap.The application of venous super-drainage technology was carried out according to needs and specific conditions. Two sets of venous passages were prepared in both recipient and donor site to form a double set of venous reflux super-drainage mode. Blood supply, swelling, exudation, secondary exploration and survival rate of the flap were observed after operation, and regularly followed-up. Results All 7 flaps survived. Venous super drainage technique was ap-plied in 7 cases. No arteriovenous crisis occurred after the operation. The flaps had good blood circulation, slight swelling, less exudation, rapid edema regression and no secondary surgical exploration. Followed-up for 2-18 (average 10.5) months, there was no infection recurred. Flaps survived well, and the donor sites healed well without sensory loss.The flexion and extension function of joint was normal. Conclusion The technique of venous super-drainage prepares 2 sets of venous systems for the free flap in the treatment of vascular pedicle in the free flap repair operation, which is conducive to reducing the venous crisis after flap surgery, reducing flap edema, reducing exudation, reducing secondary surgical exploration and improving the survival rate of the flap.
