Predictors of in-hospital mortality after acute variceal bleeding in patients with hepatocellular carcinoma and concurrent main portal vein thrombosis.

Background And Aim: Risk factors for acute variceal bleeding in patients with hepatocellular carcinoma (HCC) and concurrent main portal vein thrombosis (PVT) remain unclear. We aimed to determine risk factors of in-hospital mortality after acute variceal bleeding for HCC patients with concurrent main PVT.

Methods: We conducted a retrospective analysis of 102 HCC patients (83% men and 17% women) with concurrent main PVT and acute variceal bleeding. All patients received emergent endoscopy to define the bleeding source. Multivariable Cox proportional hazard regression analysis consisting of clinical, laboratory, and endoscopic parameters was performed to identify predictive factors for intrahospital mortality.

Results: Twenty-eight (27.5%) patients died within admission. The median survival of all patients was 56 days. Multivariable Cox proportional hazard regression analyses revealed Child-Pugh score (adjusted hazard ratio [aHR]: 1.29 for each point; 95% confidence interval [CI]: 1.11-1.50), active bleeding on index endoscopy (aHR: 7.50; 95% CI: 3.05-18.4), esophageal varices as the bleeder (compared with gastric varices, aHR: 14.3; 95% CI: 3.12-66.1), failure to control bleeding (aHR: 38.0; 95% CI: 7.44-194), and serum creatinine (aHR: 1.28 for each increase of 1 mg/dL; 95% CI: 1.09-1.50) independently predicted in-hospital mortality.

Conclusions: Hepatic reserve, active bleeding on index endoscopy, failure to control bleeding, esophageal varices as the bleeder when compared with gastric varices, and renal function were independent predictive factors for in-hospital mortality in HCC patients with acute variceal bleeding and concurrent main PVT.
