Abstract/OtherAbstract:
PURPOSE: This study correlates transjugular intrahepatic portosystemic shunt (TIPS) mortality with flow patterns in the cirrhotic liver. MATERIALS AND METHODS: Twenty-seven TIPS patients and 10 control subjects were used for this study. The authors evaluated hepatic perfusion with venous injections of Tc-99m pertechnetate before and after TIPS. Hepatic time-activity curves were analyzed for type and amount of liver perfusion. These parameters were correlated with survival for a mean follow-up of 18 months. RESULTS: The mean arterial contribution to liver blood flow was 25.4% in the normal control patients, 39.9% in patients prior to TIPS, and increased to 48.3% after TIPS. Although the proportion of arterial supply to the cirrhotic liver varied widely, TIPS mortality did not correlate with the preprocedure hepatic artery/portal venous perfusion ratio. However, patients with both an "arterialized" flow pattern and low total hepatic perfusion had higher mortality, with a mean survival of 2 months compared to patients with a more favorable perfusion profile (mean survival, 28.4 months). CONCLUSIONS: The proportion of arterial perfusion to the liver before TIPS did not affect survival. However, patients with a combination of reduced total hepatic perfusion and an arterial flow pattern had poorer survival, suggesting that both the quantity and quality of hepatic perfusion predicts TIPS outcome.
