Purpose:
To compare the safety and efficacy of left versus right internal jugular vein access for portal vein puncture during transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with a small liver and short vertical puncture distance.
Materials And Methods:
The vertical distance from the hepatic vein orifice to the puncture point of the portal vein was measured by CT and DSA. A distance ≤ 30 mm is defined as a short vertical puncture distance. After 1:1 propensity score matching (PSM), 29 patients of left internal jugular vein-TIPS (LIJ-TIPS) and 29 patients of right internal jugular vein-TIPS (RIJ-TIPS) were included. The number of needle punctures, fluoroscopy time, and radiation dose during the puncture process were statistically analyzed.
Results:
There was no significant difference in the average vertical puncture distances on CT or DSA between LIJ-TIPS and RIJ-TIPS (19.10 ± 0.60 mm vs. 19.30 ± 0.60 mm, P = 0.840; 22.02 ± 0.69 mm vs. 22.23 ± 0.64 mm, P = 0.822, respectively). The average number of needle punctures, fluoroscopy time, and radiation dose in LIJ-TIPS were significantly lower than those in RIJ-TIPS (2.07 ± 0.20 vs. 4.10 ± 0.24, P < 0.001; 78.45 ± 12.80 s vs. 201.16 ± 23.71 s, P < 0.001; 31.55 ± 7.04 mGy vs. 136.69 ± 16.38 mGy, P < 0.001, respectively). Within three punctures, the technical success rate in LIJ-TIPS was significantly higher than that in RIJ-TIPS (86.2 vs. 27.6%, P < 0.001). The incidence of hemoperitoneum in LIJ-TIPS was significantly lower than that in RIJ-TIPS (0% vs. 13.8%, P = 0.038).
Conclusion:
The left internal jugular vein could be used as primary access for TIPS creation in patients with a small liver and short vertical puncture distance.
