门静脉海绵样变的诊治进展

An update on diagnosis and treatment of cavernous transformation of portal vein

门静脉海绵样变(CTPV)是由于各种原因造成门静脉主干或分支、完全或部分阻塞,导致血管内血流受阻,门静脉压力增高,机体为缓解门静脉高压而形成大量的门静脉周围侧支血管而引起的疾病。因此,CTPV是一种代偿性病变,其代偿能力不够,无法阻止门静脉压力的上升,是导致肝前型门静脉高压的原因之一,约占门静脉高压症各病因的3.5%。因其在大体标本上表现为海绵样外观而被命名为CTPV。

Cavernous transformation of portal vein （ CTPV ） is caused by a variety reasons which partially or completely block the trunk or branches of the portal vein,inducing blood flow blocking and portal hypertension, and a large number of portal collateral vessels are established for releasing the portal hypertension.So CTPV is one of the compensated diseases which cannot decrease the portal hypertension,and becomes one of the reasons that induce prehepatic portal hypertension, accounting for about 3.5% in all kinds of portal hypertension.CTPV is named for its appearance of gross specimen.
