Abstract:
Objective To investigate the application of venous superdrainage technique based anterolateral thigh flap based on oblique branch for the soft tissue defect of proximal shank.Methods Between October,2012 and March,2017,11 cases of the soft tissue defect in proximal shank were treated.There were 8 males and 3 females with a mean age of 43 (range,26-59) years.Causes of injury:7 cases of traffic injury,3 cases of bruise,1 case of machine wound;The defect sizes ranged from 10 cm×5 cm to 13 cm×10 cm,with fracture or plate exposure.Accord ing to the size of the defect,the distally based anterolateral thigh flap was designed to repair the defect.The flap sizes ranged from 14 cm×6 cm to 16 cm×8 cm.The oblique branch and their accompanying vein with great saphenous vein was anastomosed to construct the venous superdrainage,and the donor site suture directly.Three cases followed-up by WeChat,and 8 cases by return visit.Results Distally based anterolateral thigh flaps were derived from oblique branches,and no arteriovenous crisis occurred postoperatively.Eleven flaps healed well after operation.There were no distal end blood supply disorder.Followed-up for 6-12 months,the flaps survived well.The texture was closed to the surrounding skin,and no ulcer exposed.There were no serious complications in donor site.And the thighs were linear scars.Conclusion The distally based anterolateral thigh flap based on oblique branch have a long vascular pedicle.The venous superdrainage technique can effectively avoid venous crisis,and improve the survival quality of the flap and the survival rate.
