Transplant renoportal vein conduit for complete mesenteric thrombosis: a case report

Portal vein thrombosis, which is present in up to one quarter of patients with end-stage liver disease, presents a technical challenge at the time of liver transplantation. Thromboendovenectomy when feasible has been advocated in these patients. However, in patients with complete mesenteric thrombosis where this technique is typically not successful, a number of alternative techniques have been attempted including caval transposition, portal arterialization, and multivisceral transplantation often with discouraging results. We present herein a single case where transplant renal vein outflow was used to provide portal vein inflow in a patient with complete mesenteric thrombosis undergoing simultaneous liver-kidney transplant.
