数字减影血管造影术在经颈静脉肝内门腔分流术中的应用

Application of Digital Subtraction Angiography in Transjugular Intrahepatic Porto-systemic Stent Shunts

采用数字减影血管造影术（ＤＳＡ）对７例肝硬化伴门脉高压患者行经颈静脉肝内门腔分流术（ＴＩＰＳＳ）获得成功。本文探讨了直接和间接门脉造影、肝静脉造影的方法和作用及应用不同的减影程序和角度投照方法是清晰显示靶血管解剖形态，获取定位图像的关键，并对各种门脉定位方法的价值进行了评价，认为间接门脉造影结合体外超声导引是门脉定位的最佳方法。

Transjugular intrahepatic porto-systemic stent shunt(TIPSS)was performed successfully in 7 cases of liver cirrhosis with portal hypertension by using digital subtraction angiography(DSA) technique, The techniques and application of direct and indirect portal venography, hepatic venography were studied. Use of optimal subtraction procedures and multi-angle view was key to visualizing the anatomical relationship of hepatic vein, portal vein. The different localization methods were evaluated. It is concluded that combination of indirect portal venography and ultrasonic guidance is the best approach for localization of portal vein.
