Risk factors for inferior right hepatic vein occlusion following right lobe living donor liver transplantation: a single-center experience with 240 cases.

Inferior right hepatic vein remained patent in 69.61% (n = 142) of patients, whereas 30.39% (n = 62) experienced inferior right hepatic vein occlusion.

Early inferior right hepatic vein occlusion (within 30 days) occurred in 52 patients (83.9% of occluded cases).

In early occluded cases, the mean inferior right hepatic vein diameter was significantly smaller (4.92 ± 1.61 mm) compared to the open group (6.02 ± 1.72 mm; p < 0.001).

Additionally, the GWRW ratio was significantly higher in the late occluded group (p < 0.001), with a mean GWRW ratio of 1.08 ± 0.21 in the open group and 1.43 ± 0.35 in the occluded group.
