Transjugular liver biopsy after transjugular intrahepatic portosystemic shunt (TIPS) or direct intrahepatic portocaval shunt (DIPS): Is it feasible, effective, and safe?

Abstract

To evaluate our experience with transjugular liver biopsies (TJLB) in patients with previously placed transjugular intrahepatic portosystemic shunt (TIPS) or direct intrahepatic portocaval shunt (DIPS). A single-institution retrospective review was performed looking at all TJLBs in patients with previously placed TIPS or DIPS over the past seven years. There were six men and one woman (mean age 57.9±8.8 [SD] years; range: 47-71 years). Patient demographics, indications, procedural details, laboratory data, complications, and pathology were recorded. Patients with occluded TIPS were excluded from this study. Seven TJLBs were performed, five in patients who had a TIPS and two who had a DIPS. Of the patients with TIPS, biopsies were performed from the same hepatic vein as TIPS in three procedures and from a different hepatic vein in two procedures. In DIPS patients, both biopsies were performed from the right hepatic vein. The reasons for the transjugular rather than the percutaneous approach to liver biopsy included ascites, coagulopathy, or need for concurrent TIPS/DIPS evaluation and/or revision. All procedures were technically successful with adequate samples obtained. There were no immediate or delayed complications. Our results suggest that if needed a TJLB can safely and effectively be performed in patients with previously placed TIPS or DIPS.
