摘要
目的:作者通过门静脉造影观察分析了门静脉起始位置、走行方向、长度、宽度、分叉位置、角度及肝内分支形态等,研究门静脉正常解剖和变异,为TIPS提供应用解剖。材料与方法:本组88例门静脉造影,43例(门脉高压组)为经肠系膜上动脉门静脉造影;45例(非门脉高压组)为经腹腔动脉、脾动脉门脉造影和术中门脉造影。造影摄片X线管与胶片间距为100cm。结果与结论:大多数门脉主干起始位置在胸12和腰1平面,由肠系膜上静脉和脾静脉汇合而成,位于相应椎体右缘,少数位于胸11或腰2平面。门脉长度平均7.8cm,门脉高压组门脉宽度1.80cm,非门脉高压组1.21cm。门脉高压组肝内分支宽度明显宽于非门脉高压组,左支平均增宽0.43cm,右支平均增宽0.5cm。肝内门脉分支90%在分叉部分为左、右2支,10%分为左、右、中3支。门脉分叉位置门脉高压组多位于胸10平面,而非门脉高压组多位于胸11平面。
