前臂远端复合血管网带蒂皮瓣的血供特点及应用

目的探讨前臂远端蒂复合血管网皮瓣的血供特点及临床疗效。方法应用包含深筋膜、皮神经及浅静脉的前臂远端蒂复合血管网皮瓣修复手、腕部创面26例,皮瓣面积5cm×6cm～6cm×12cm。结果本组随访3～8个月,26例皮瓣完全成活,皮瓣不臃肿、耐磨、质地优良。结论皮神经、浅静脉营养血管网与真皮下及深筋膜血管网经穿动脉相互联系,构成三维、立体、轴向的血供构筑,是皮瓣存活的解剖基础,蒂部远端的主干血管穿支是皮瓣的血供来源,皮瓣操作安全,成活率高。

Blood supply to distally pedicled composite vascular net flap of forearm and its clinical application

Objective To study the boold supply to the distally pedicled composite vascular net flap of forearm and its clinical application.Methods From 2000,We repaired 26 cases with skin defects in hand by using the distally pedicled composite vascular net flap of forearm.Results All of the flaps were reviewed, with more than 3 months of following-up.Conclusion Plexus around the cutaneous nerves and the superficial vein is connected with the superficial subdermal plexus, and the deep facial plexus by perforators from the underling main arteries, forming a three-dimensional vascular network and in a sort of longitudinal axiality, which is the anatomic base of flap blood supply. The advantage of this flap is its constant and reliable blood supply without sacrifice of the main artery.The elevation of the flap is simple and rapid, and the flap has a higher survival rate.
