Hemorrhage risk with transjugular intrahepatic portosystemic shunt (TIPS) insertion at the main portal vein bifurcation with stent grafts.
PURPOSE:The purpose of this study was to assess the incidence of major hemorrhage after transjugular intrahepatic portosystemic shunt (TIPS) insertion using a stent graft at the main portal vein bifurcation. PATIENTS AND METHODS:TIPS insertion using stent grafts was performed in 215 patients due to non-variceal hemorrhage indications. There were 137 men and 78 women, with a mean age of 57 years±10.6 (SD) (range: 19-90 years). Based on retrospective review of portal venograms, TIPS inserted within 5mm from the portal vein bifurcation were considered "bifurcation TIPS", while those inserted 2cm or greater from the bifurcation were considered intrahepatic. Suspicion for acute major periprocedural hemorrhage were categorized as low, moderate, and high, based on the number of signs of hemorrhage. RESULTS:Of 215 TIPS inserted for purposes other than hemorrhage, the TIPS was inserted at the portal bifurcation in 41 patients (29 men, 12 women; mean age, 55.9±11.7 (SD); range: 26-79 years) and intrahepatic in 62 patients (37 men, 25 women; mean age, 57.6±10.6 (SD), range: 34-82 years), whereas 112 were indeterminate in location. No active extravasations were identified on post-TIPS portal venograms. Suspicion for acute major hemorrhage was moderate or high in 3/41 (7%) of patients in the TIPS bifurcation group compared to 5/62 (8%) in the intrahepatic TIPS group (P>0.99). There were no significant differences in 30-day mortality rates (1/41 [2%] and 3/62 [5%] respectively; P> 0.99). No deaths or interventions were attributed to acute hemorrhage. CONCLUSION:TIPS insertion at the portal bifurcation with stent grafts did not incur an elevated risk of hemorrhagic complications.
