目的 了解多层螺旋CT门体侧支循环的显示情况,并探讨其临床意义。方法 对2003 -04 ~2003-12北京友谊医院43例肝硬化门脉高压病人分别进行胃镜和多层螺旋CT门脉成像。了解食管胃底静脉曲张及门体侧支循环形成情况并加以比较,同时分析其与肝功能之间的相关性。结果 多层螺旋CT能清晰地显示门静脉及其侧支血管,胃镜显示食管静脉曲张38 /43(88. 4% ),胃底静脉曲张23 /43 (53 .5% ),螺旋CT显示食管静脉曲张37 /43(86% ),胃底静脉曲张25 /43(58 .1% )。对食管胃底静脉曲张的显示与胃镜有高度一致性,Kappa值分别为0 .876和0. 903。结论 多层螺旋CT结合多种三维重建技术进行图像后期处理,能产生高质量的血管图像,三维多层螺旋CT门脉造影,能显示肝硬化病人门体侧支血管,可能是这个领域中理想的血管成像技术。
Objective To understand the display of collateral circulation of multi-slice spiral CT portosystemicus and to discuss its clinical significance. Methods Forty - three patients with cirrhosis and portal hypertension at Beijing Friendship Hospital from 2003 to 2004 were enrolled in this study. To understand esophageal varices and the formation of portal collateral circulation and to compare and analyze its correlation with liver function. Results Multi-slice spiral CT clearly showed the portal vein and its collateral vessels. Gastroscopy showed esophageal varices 38/43 (88.4%) and gastric varices 23/43 (53.5%). Spiral CT showed esophageal vein Varicose veins 37/43 (86%), gastric varices 25/43 (58.1%). The findings of esophageal and gastric varices were highly consistent with gastroscopy with Kappa values of 0.0876 and 0.903, respectively. Conclusions Multi-slice spiral CT combined with a variety of three-dimensional reconstruction techniques for image postprocessing can produce high-quality images of blood vessels, three-dimensional multi-slice spiral CT portal angiography, revealing the portal collateral vessels in patients with cirrhosis, and may be ideal in this field Angiography.
