通过对45例下腔静脉阻塞血管造影的影像学分析,将其 X 线解剖分为三个基本类型:1型为肝静脉入口平面膜性阻塞占40%(18例);2型为肝静脉入口平面以下至肾静脉入口平面之间阻塞占44.4%(20例);3型为下腔静脉广泛性闭塞占15.6%(7例)。文章依据其 X 线分型提出介入治疗的原则,并对 X 线分型的临床意义进行了讨论。
According to the imaging analysis of 45 cases of inferior vena cava occlusion angiography, the X-ray anatomy was divided into three basic types: type 1 hepatic venous portal plane membranous obstruction accounted for 40% (18 cases); type 2 hepatic vein 44.4% (20 cases) occured between the entrance plane and the plane of the renal vein entrance, and 15.6% (7 cases) had type 3 occlusion of the inferior vena cava. The article puts forward the principle of interventional therapy according to its X-ray classification and discusses the clinical significance of X-ray classification.
