摘要
目的 观察前臂正中浅静脉腕部分支的解剖特点 ,并总结其在复杂断指再植中的应用经验。方法 观察 10 0名 2 0 0侧健康成人前臂正中浅静脉腕部分支的出现率。对 2 8例 3 4侧成人前臂正中浅静脉腕部分支进行显微解剖观察 ,并测量其口径。临床为 2 5例伴指动脉缺损的断指 ,取患侧前臂正中浅静脉腕部分支桥接指动脉后进行再植。结果 前臂正中浅静脉腕部分支主干的出现率为 98% ,细支的出现率为 90 %。分支主干口径 0 .5 6± 0 .0 5mm( x±s,下同 ) ,细支口径 0 .3 6± 0 .0 5mm。 2 5例断指再植后 2 4h内发生动脉危象 5例 ,2例手术切除动脉栓塞段后重新吻合 ,3例保守治疗后均成活。 2 0例断指术后顺利成活。结论 前臂正中浅静脉腕部分支的主干和细支解剖位置恒定 ,口径合适 ,适用于各平面断指再植中行血管移植。
Objective To observe the anatomical characteristics of the wrist branches of nd summarize its application in complicated digital replantation.Methods The appearance rate of the wrist branches of median superficial vein was observed in 200 forearms of 100 healthy adults. Microanatomical observation of the vein and its branches was done in 28 cases (34 sides). The diameter was measured. The vein from the affected side was harvested to bridge the digital artery defect in 25 cases of digital replantation.Results The appearance rate of the wein was 98 % in a thick branch fashion and 90 % in a fine branch fashion. The diameter was 0.56 ± 0 05 mm and 0.36 ± 0.05 mm respectively. Arterial crisis occurred within 24 hours postoperatively in 5 cases of the 25 replantations. The crisis was reversed after thrombectomy and reanastomosis of the artery in 2 cases and conservative treatment in 3 cases. All the 25 replanted digits survived. Conclusions Both the thick and fine wrist branch of the median superficial vein have a constant anatomical location and suitable diameter. It is a preferable vessel graft in digital replantation.
