Double C-Arm Digital Subtraction Angiography Guidance During Transjugular Intrahepatic Portosystemic Shunt Placement.

BACKGROUND This study aimed to evaluate the safety and efficacy of portal vein puncture with a new guidance system using double C-arm digital subtraction angiography (DSA) during transjugular intrahepatic portosystemic shunt (TIPS) placement. MATERIAL AND METHODS The procedure details of TIPS placements performed on 39 patients in our center between January and December 2021 were retrospectively analyzed. The procedure was performed under double C-arm DSA guidance (study group) and C-arm DSA (control group) in 18 and 21 patients, respectively. We analyzed the procedure's technical success, duration of the overall procedure, portal vein puncture, fluoroscopy, radiation exposure, complications, and mortality and morbidity rates 30 days after the procedure. RESULTS TIPS placement was performed successfully in all patients. The mean portal vein puncture time in the study group (9±5.7 min) was significantly shorter than in the control group (33±14.9 min, p=0.02). The complete mean dose area product of the procedure showed no significant differences (study group, 126±53 Gy/cm²; control group. 142±66 Gy/cm²; p=0.42). The intraprocedural complication rates were 0% and 19% in the study and control groups, respectively (p=0.04). The 30-day post-procedural mortality rate in the control group was 4.8% (1/21), with no deaths from technical complications. CONCLUSIONS Double C-arm DSA guidance is a safe and effective method to assist TIPS placement. This approach may result in shorter portal vein puncture time and lower intraprocedural complication rates.
