Pharmacologic prophylaxis of portal venous system thrombosis after splenectomy: a meta-analysis.

ABSTRACT: Portal venous system thrombosis (PVST) is a life-threatening complication of splenectomy. A meta-analysis was conducted to explore the role of pharmacologic prophylaxis of PVST after splenectomy. Overall, 359 papers were initially identified via the PubMed, EMBASE, and Cochrane Library databases. Eight of them were eligible. The incidence of PVST after splenectomy was significantly lower in patients who received the preventive measures than in those who did not (odds ratio [OR]: 0.33, 95% confidence interval [CI]: 0.22-0.47, P < 0.00001). Subgroup analyses demonstrated that the significant difference remained in studies including patients with portal hypertension (n = 6), but not in those including patients with hematological diseases (n = 2); the significant difference remained in studies
