Objective To investigate risky factors,and predictability of portal vein thrombsis in patients with portal hypertension caused by hepatic cirrhosis after spleenectomy and portaazygous devascularization. Methods Between Jan 2004 to Nov 2009,clinical data of 27 patients suffering from postoperative PVT were compared with 37 patients admitted during the same period without postoperative PVT. Results There were 4 factors proved to be risk factors for PVT.Perioperative peripheral platelet count (postoperative to preoperative) 、D-dimer、the whole blood viscosity and the blood flow of portal vein postoperatively.The right predictive rate of PVT was 87.3%. Conclusion The risk factors of PVT are the ratio of platelets、D-dimer、the whole blood viscosity and the blood flow of portal vein postoperatively.By this method it is probable that postoperative PVT is predictable.

Objective To study the risk factors for spontaneous rupture of primary hepatic carcinoma.Methods The clinical data of 31 patients with spontaneous rupture of primary hepatic cancer admitted to our hospital from Jan 1999 to Dec.2008 were retrospectively analyzed,and compared with 31 randomly selected concurrent patients without rapture of HCC.Results Three factors were shown to be the risk factors for spontaneous rupture of primary hepatic carcinoma.Those were APTT,HBeAg and the greatest height of tumor protrusion above the surface of liver.Conclusions APTT,HBeAg and the greatest height of tumor protrusion above the surface of liver are risk factors for spontaneous rupture of primary hepatic carcinoma.
