ABSTRACT
BACKGROUND:
Due to the invisibility of the portal vein (PV), how to puncture the PV accurately and safely in transjugular intrahepatic portosystemic shunt (TIPS) creation remains a challenge of the procedure.OBJECTIVES:
We aimed to provide the first evaluation of the safety, feasibility, and efficiency of cone beam computed tomography (CBCT)-based three-dimensional (3D) dual-phase vascular image fusion for interventional real-time guided PV puncture during TIPS procedures. MATERIALS ANDMETHODS:
From January 2021 to May 2021, 13 patients undergoing TIPS were prospectively enrolled in this study. Images of the hepatic artery (HA) and PV in 3D were acquired and overlaid on interventional fluoroscopy images in a dual-phase display mode for real-time PV puncture guidance. The number of PV puncture attempts, puncture time, overlaid image accuracy, dose area product, fluoroscopy time, and interventional complications were recorded.RESULTS:
Portal vein puncture guided by CBCT-based 3D dual-phase vascular image fusion was successfully performed on 92.3% (12/13) patients. The mean number of PV puncture attempts was 1.8⯱ 0.7 (1-3). The mean puncture time and fluoroscopy time was 3.5⯱ 1.2 (2-6)â¯min and 25.1⯱ 9.4 (15-45)â¯min, respectively. The mean dose area product was 39.49⯱ 7.88 (28.81-52.87)â¯mGym2. The error between the reference position of the fusion image and the interventional PV angiography image was less than 0.5â¯cm. No interventional complication was observed.CONCLUSION:
Our results show that 3D dual-phase vascular image fusion might be a safe and feasible technique for interventional real-time guided PV puncture during TIPS. This novel technique might help to reduce the number of PV puncture attempts and the puncture time as well as lower the risks of interventional complications.
