BACKGROUND/AIMS: Portosystemic shunts offer a symptomatic treatment for portal hypertension. Their main disadvantage is decreased perfusion of the liver with portal blood. Change of peripheral shunts into total shunts after a period of time is described. This study aims to evaluate long-term hemodynamic changes in peripheral portosystemic shunts.
The study was based on 12 patients in whom distal splenorenal shunts 8 patients) and mesocaval shunts (4 patients) were indicated respectively. Duplex sonography was used to measure the blood flow in the portal, splenic and mesenteric veins before shunt surgery and minimally 14 months postoperatively.
It was found that the reduction of the portal blood flow was not critical and no centralization of the shunt was observed.
Long-term blood flow in the portal vein was not severely reduced after peripheral portosystemic shunt creation, therefore the peripheral portosystemic shunt still has a role in the treatment of some patients with portal hypertension.
背景/目的:门体分流术为门静脉高压提供了一种对症治疗方法。其主要缺点是门静脉血对肝脏的灌注减少。有研究描述了一段时间后外周分流转变为完全分流的情况。本研究旨在评估外周门体分流术的长期血流动力学变化。
该研究基于12例患者,其中分别有8例行远端脾肾分流术,4例行肠系膜上静脉-下腔静脉分流术。在分流手术前及术后至少14个月,采用双功超声测量门静脉、脾静脉和肠系膜静脉的血流。
发现门静脉血流减少并不严重,且未观察到分流的集中化。
在外周门体分流术后,门静脉的长期血流并未严重减少,因此外周门体分流术在某些门静脉高压患者的治疗中仍具有一定作用。
