摘要
目的:阐明髂间三角区内血管的分布规律,为腹腔镜前路L5～S1椎间盘手术提供安全靶区。方法:31例经动脉灌注红色乳胶的成人防腐固定腰椎标本,年龄58.2岁。观测并分析髂间三角内与腹腔镜前路L5～S1椎间盘手术相关的血管解剖数据。结果:L5～S1椎间盘的高度、宽度分别为(1.87±0.21)cm、(5.07±0.60)cm;主动脉杈(AB)与髂总静脉汇合处(CCIV)分别位于L5～S1椎间盘上缘(3.97±1.24)cm、(2.75±1.46)cm处;夹角分别为(52.4±12.0)°、(78.4±22.1)°;骶正中动脉(MSA)存在于所有的标本中,在L5～S1椎间盘上、下缘处的外径分别为(0.16±0.04)cm、(0.14±0.05)cm;上、下缘水平到右髂动脉(RIA)的距离分别为(2.02±0.81)cm、(2.74±0.83)cm。左髂静脉(LIV)到右髂动脉的平均距离为3.60cm,占椎间盘宽度的71.3%(32.3%～124.4%)。结论:髂间三角内的血管解剖能满足腹腔镜前路L5～S1椎间盘手术要求,可作为手术治疗椎间盘疾患的选择靶区。
Objoetive： To clarify the vessel distribution in interiliac triangle, and provide safe region for anterior laparoscopic surgery in L5-S1 disc space. Methods： 31 lumbar preserved adult specimens perfused with red latex through arteries, 58.2 years old averagely, were used in this study. Vascular anatomy related to anterior laparoscopic surgery in L5-S1 disc were performed. Results： The height, width of L5-S1 disc was （1.87±0.21） cm and （5.07±0.60） cm, respectively. The distance between the top of L5-S1 disc and aortic bifurcation （AB） / the conflt,vnce of the common Iliac veins （CCIV） were （3.97±1.24） cm and （1.88±1.36） cm, respectively. The angle of AB/CCW was （52.4±12.0）°and （78.4±22.1） °, respectively. The median sacral artery （MSA） presented in all specimens. The diameters of the top and bottom of L5-S1 disc were （0.16±0.04） cm and （0.14±0.05） cm, while the distance between right Iliac artery （RIA） and MSA at the level of the top and bottom of L5-S1 disc were （2.02±0.81） cm and （2.74±0.83） cm. The average distance of the left iliac vein （LIV） to RIA was 3.60cm, which is 71.3% （32.3%-124.4%） of the total width of the disc. Conclusions： Vascular anatomy in our paper can provide indication for anterior laparoscopic surgery in L5-S1 which can be used as an alternative target region for the treatment of intervertebral disc disease.
