Abstract
Objective To study the mechanism of acute portal vein thrombosis (APVT) after pericardial devascularization with splenectomy for the treatment of portal hypertension. MethodsThe expression of intercelluar adhesion molecule-1(ICAM-1) in spleen veins of 34 patients with portal hypertension and control vessels was studied by immunohistochemistry. Samples from spleen veins were examined by HE staining. Results The ICAM-1 level was higher in the spleen vessels in portal hypertensive (PH) patients than in controls (P0.01). Eight PH cases suffered from postoperative APVT, whereas there was no APVT developed in the 34 control non PH cases undergoing splenectomy for ruptured spleen (P0.05). Conclusions The overexpression of ICAM-1 in portal system and the hyperplasia of intimal epithelium and hylinization contribute to the high incidence of APVT in PH patients undergoing pericardial devascularization.
