N2 - Purpose: To compare procedure characteristics and outcomes when TIPS is performed under intracardiac echocardiography guidance (iTIPS) compared to conventional fluoroscopic guidance (cTIPS). Materials and methods: A retrospective propensity-matched study of 30 iTIPS and 30 cTIPS procedures from January 2014 to March 2017 at a single US high volume academic medical center was performed. iTIPS and cTIPS cases were propensity score matched using predictive variables: age, race, gender, etiology of liver disease, indication for TIPS, MELD score, and portal vein patency. Procedure characteristics and post- procedure outcomes were compared between propensity-matched groups including: total procedure time, technical success, radiation dose, contrast volume, complication rate, 30- day mortality, and revision rate within 3 months. Results: Radiation dose (875.3 vs 457.4 mGY, p = 0.039) and contrast volume (141 vs 103 mL, p = 0.005) were significantly decreased in the iTIPS versus the cTIPS group. There was no significant difference in procedure time (81.5 cTIPS vs 84 min iTIPS) or rate of TIPS revisions within 3 months. Average operator experience in the iTIPs group was 4.2 years and cTIPS group 11.0 years (p = 0.0004). All procedures were technically successful with no mortalities within 30 days. Conclusion: iTIPS resulted in significantly reduced radiation dose and contrast volume. However, there was no difference in total procedure time or overall outcomes despite greater operator experience in the cTIPS group.
