Abstract
Extensive portosplenomesenteric thrombosis is regarded as a relative contraindication to liver transplantation because of the complexity of the surgical procedure. This report describes a case of living-donor liver transplantation (LDLT) for a patient with extensive portosplenomesenteric thrombosis, in whom portal flow was successfully restored by intraoperative transplenic portal vein and superior mesenteric vein stenting after surgical thrombectomy. The patient's liver function remained normal with a patent portal vein stent 6 months after LDLT, and Doppler ultrasonography demonstrated a normal wave form for portal flow. To the best of our knowledge, this is the world's first case of endovascular management of the portal vein via percutaneous transsplenic access during LDLT, demonstrating that transsplenic access can be an alternative approach without liver graft injury when the superior mesenteric vein branch and inferior mesenteric vein cannot be used as access routes.
