Abstract

Transjugular intrahepatic portosystemic shunts (TIPS) have been used for almost 40 years as a safe and effective alternative to surgical shunts, mostly in the setting of portal hypertension. Well described procedural complications include hepatic encephalopathy, hemorrhage, liver infarction and failure. The risk of post procedural acute kidney injury (AKI) associated with intraprocedural intravenous contrast administration has not been evaluated. Using a retrospective chart review of all consecutive patients undergoing a TIPS procedure as part of routine clinical care between 2001 and 2011, we examined whether the volume of administered intravenous contrast was associated with AKI. Of 163 patients who had a TIPS procedure, 16% developed AKI as defined by a 0.3 mg/dl increase in serum creatinine within 48 h of the procedure. In adjusted analysis, a 50 ml increase of intravenous contrast was associated with a 1.27 (95% CI 1.01-1.60), p = 0.04 increased risk of AKI. Baseline serum creatinine was also associated with post procedural AKI; a 0.1 mg/dl increase in creatinine was associated with a 1.17 (1.04-1.31), p = 0.008 risk. In patients with underlying kidney dysfunction, a 50 ml increase of intravenous contrast was associated wi...Continue Reading
