摘要
目的 :为带旋髂深血管蒂髂骨瓣转位腰骶段椎体植骨融合术提供应用解剖学基础。方法 :在3 0具共 60侧灌注红色乳胶的成年尸体上 ,解剖观察旋髂深动脉的起始、走行、分支、分布范围及其毗邻结构 ,测量有关数据 ;摹拟转位情况、测量旋髂深动脉的起点至S1椎体中部、L5～S1椎间、L5椎体中部的距离 ,并用量角器测量旋髂深动脉主干向内转位的角度。结果 :旋髂深动脉起于髂外动脉者占 63 .3 % ,起于股动脉者占 3 6.7%。起点外径 ( 2 .6± 0 .4)mm ,腹壁肌支外径 ( 1.4± 0 .4)mm ,旋髂深动脉的主干延续为髂嵴支 ,外径 ( 1.8± 0 .4)mm ,沿途发出许多小的分支进入髂嵴 ,以最后一个分支作为终点测量其蒂长为( 10 .7± 0 .7)cm ,旋髂深动脉起点至L5椎体中部距离为 ( 11.2± 0 .7)cm ,至L5～S1椎间距离为 ( 10 .1±0 .5 )cm ,至S1椎体中部距离为 ( 9.7± 0 .6)cm ,向内旋转角度为 ( 63 .5± 3 .5 )°。结论 :带旋髂深动脉蒂髂骨瓣转位腰骶段椎体植骨融合具有可行性。
Objective: To provide the anatomic basis for the grafting-fusion of lumbosacral vertebrae with iliac flap supplied by deep iliac circumflex artery (DICA) pedicle. Methods: The origin, couse, and branches of the DICA were observed on 30 adult cadaver (60 sides), the specimens were prepared by artery perfusion with color latex, then the length of DICA pedicle and the distance from the DICA origin to L 5 mid-vertebrae, to L 5～S 1 intervertebrae and to S 1 mid-vertebrae were measured respectively, the inward angle about DICA for transposition was also measured by goniometer. Results: The rate of DICA originated from the external iliac artery was 63.3%(38 sides), from femoral artery was 36.7%(22 sides). The outer diameter of the DICA at the origin was 2.6±0.4 mm.The DICA run laterally and upwardly to the iliac crest. In the couse of running DICA gave off 3～8 branches entering the iliac bone, and the ending branch was used as the terminal point of the DICA pedicle. The pedicle length was 10.7±0.7 cm, the distance from the initial point of DICA to L 5 mid-vertebrae, to L 5～S 1 intervertebrae and to S 1 mid-vertebrae were 11.2±0.7 cm, 10.1±0.5 cm and 9.7± 0.6 cm respectively.The inward angle of transposition of the DICA was 63.5°±3.5°.Conclusions: It is suggested that using the iliac flap with DICA pedicle for the grafting-fusion to the lumbosacral vertebrae is feasible.
