Abstract: 目的通过多层螺旋CT(multi-detecter row computed tomography,MDCT)了解食管胃底静脉曲张及与之相关的侧支循环,为食管胃底静脉曲张破裂出血治疗方案的选择和预后的判断提供客观依据.方法选择51例临床证实的肝硬化门静脉高压患者,其中胃镜显示食管静脉曲张51例,伴胃底静脉曲张31例.对所有患者进行MDCT血管成像,重点观察食管胃底静脉曲张及相关侧支循环.结果 MDCT血管成像能清晰地显示肝硬化门体侧支血管,并显示所有食管静脉曲张.MDCT显示胃底静脉曲张32例(62.7%),与胃镜检查结果(31/51,60.8%)比较,两者具有高度一致性,Kappa值为0.876.食管曲张静脉几乎全部由胃左静脉供血,30例(58.8%)单纯由胃左静脉前支供血,21例(41.2%)伴有食管旁静脉;24例(75%)胃底曲张静脉为单纯胃左静脉供血,3例(9.4%)由胃短(胃后)静脉供血,5例(15.6%)为胃短(胃后)和胃左静脉双重供血,双重供血者因胃底静脉曲张和食管静脉曲张常相互交通,所以这些病例胃短(胃后)静脉也同时参与食管静脉曲张的形成.结论 MDCT能较清晰地显示食管胃底静脉曲张侧支循环.食管静脉曲张主要由胃左静脉供血,大部分由前支经贲门进入曲张静脉,部分伴有食管旁静脉.胃底静脉曲张大部分由胃左静脉供血,但小部分则由胃短系统供血.
