Splenectomy Before Recipient Hepatectomy for Inflow Modulation Using a Very Small Modified Right Hemiliver Graft: A Case Report.

Portal inflow modulation has become standard practice in many transplant centers performing living donor liver transplantation. This is believed to counteract the deleterious effects of excess portal flow into a small-for-size graft. A splenectomy negates the contribution of the splenic vein flow completely and thereby substantially reduces portal inflow. Although it has been adopted as a standard strategy by many Japanese centers for inflow modulation, especially while using left hemiliver grafts, there is justifiable apprehension about its usage due to potential increases in morbidity. Described here is a splenectomy performed while using a modified right hemiliver graft with a graft to recipient weight ratio of 0.49. The challenges in decision making and reasons regarding how such a small graft might have worked without manifestations of small-for-size/flow syndrome are discussed. [ABSTRACT FROM AUTHOR]
