Background: Treatment options for patients presenting with life-threatening splanchnic ischemia, including that of the intestine and liver, could previously only receive salvage surgery and attempted medical revascularization. We propose that urgent liver transplantation (LT) for acute liver failure (ALF) due to massive liver necrosis should be considered as a life-saving treatment. We successfully performed urgent living donor LT for nonocclusive hepatic ischemia accompanied by nonocclusive mesenteric ischemia (NOMI). Case: An 11-month-old boy with biliary atresia whose jaundice was re-elevated after Kasai portoenterostomy underwent cysto-jejunostomy. Three hours after the uneventful operation, tachycardia, hypotension, and unconsciousness suddenly occurred. Computed tomography revealed whole-liver and massive splenic and focal intestinal ischemia without any vessel occlusion. Urgent LT was performed on postoperative day 3 because intensive therapies, including prostaglandin E1 administration, blood transfusion, and continuous hemodiafiltration, were not effective and the patient had developed life-threatening bradycardia and hypotension. Intraoperative findings included whole-liver necrosis and splenic ischemia and segmental ileal necrosis without any vessel thrombus. LT and necrotic intestinal resections by end-to-end anastomosis were performed. Massive liver necrosis with Gram-positive cocci was histopathologically identified, indicating bacterial translocation due to NOMI. The post-LT course was uneventful, and the neurologic outcomes were uncomplicated. Conclusions: Urgent LT was successfully completed for ALF with NOMI. LT is the sole treatment for the refractory ALF, and undelayed determination is important to rescue.
