摘要
对13例行颈静脉肝内门体静脉分流术(TIPS)的肝硬化患者,于术前行MRI血管定位检查。并将10例正常肝脏标本按TIPS要求进行解剖对照。笔者认为:MRI斜线定位法准确、安全、简便。11例(84.6％)按本设计法TIPS穿刺成功。2例(15.4％)由于静脉狭窄和肝右静脉起始位置低下失败。两穿刺点所在斜面与正中矢状面夹角为30.3°±7.7°。在此斜面上,由肝右静脉至门静脉右支的夹角为23.5°±1.6°,穿刺点间距为40.1±6.9mm。
Vascular localization by magnetic resonance imagmg(MRI) was carned out m 13 cases of hepalocirrhosis hefore TIPS. Ten normal liver specimens were anatomizecl according to the requirement of TIPS to correlate with MR findings. It was suggested that the obhque line localization method of MR be accurate.safe and easy. The puncture of TIPS were successful in 11 cases(84. 6%) and failed in iwo cases(15. 4%) due to a constric-tive hepatic vein and a low positional right vein respectively. The angle between the inclined plane and the sagittal plane is 30. 3° ± 7. 7°.On the inclined plane, the angle is 23. 5° ±1. 6° and the shunt distance is 40. 1±6. 9mm from right hepatic vein to right portal vein.
