Living donor hepatectomy is not without risks, and some complications can end up with serious morbidities if not timely diagnosed and appropriately managed. In this report we described a very unusual but significant surgical problem in living liver donor surgery in which a significant narrowing occurred in the inferior vena cava after closure of stump of the right hepatic vein and inferior right hepatic vein close to the right hepatic vein together, and describe the cavoplasty technique used to repair this narrowing. To the best of our knowledge, the technique of solving this problem in living liver donors was described only once in the literature, which was published by our team in 2012.
