Enhancing transjugular intrahepatic portosystemic shunt procedure efficiency with digital subtraction angiography image overlay technology in esophagogastric variceal bleeding.

Notably, the puncture time was reduced, from an average of 53 ± 13.7 minutes in the ultrasound-guided group to 27 ± 14.0 minutes in the DIT-guided group, corresponding to a highly significant reduction ( P < 0.001).

The number of punctures required also tended to be lower in the DIT-guided group, with an average of 1.2 ± 0.4 punctures vs 1.7 ± 0.7 in the ultrasound-guided group, although this difference narrowly failed to reach statistical significance ( P = 0.074).
