Acute portal vein thrombosis secondary to donor/recipient portal vein diameter mismatch after orthotopic liver transplantation: a case report.
The incidence of portal vein thrombosis in end-stage liver disease is estimated as varying between 5% and 21%, whereas in candidates undergoing liver transplantation, this is 3-13%. Portal vein thrombosis occurring after liver transplantation can be managed surgically by thrombectomy, retransplantation, splenorenal shunt, or Wall-stent placement, or nonsurgically by angioplasty, local high-dose infusion of thrombolytic agents, combination of portal thrombolysis, or embolization of a pre-existing spontaneous splenorenal shunt. We report a case of portal vein thrombosis after liver transplantation diagnosed on postoperative day 1 in a 57-year-old patient who received a liver from an 8-year-old donor. The patient was successfully treated surgically with portal vein thrombectomy and systemic anticoagulation. Portal vein thrombosis, in this case, was considered to be secondary to size discrepancy between the donor and the recipient portal veins. Routine use of daily Doppler ultrasound was the key factor in early diagnosis.
