Successful living donor left liver transplantation by using liver graft with multiple large cysts: a case report

There are few reports regarding the use of liver grafts with multiple large cysts in living donor liver transplantation. A 40-year-old woman who was diagnosed with Wilson's disease underwent living donor left liver transplantation; the donor was her 67-year-old mother. The liver graft had multiple large cysts, with a maximum diameter of 9 cm. At donor hepatectomy, the largest cyst and one small cyst were fenestrated, because they were located in the left paramedian sector; the other cysts were left intact. After transplantation, the liver graft exhibited good function with no cyst-related complications, such as hemorrhage, infection, or rupture, despite slight enlargement of the cysts. Thus, a liver graft with multiple large cysts is transplantable. However, the necessity of treating large cysts remains debatable.
