The inferior mesoiliacal shunt: A novel shunt for refractory rectal variceal bleeding due to splanchnic thrombosis.

ABSTRACT

Surgical shunt therapy may be required when pharmacologic, endoscopic, and radiologic treatment of chronic splanchnic vein thrombosis have failed. In this case report, we present a new interposition shunt for the treatment of refractory rectal variceal bleeding the inferior mesoiliacal shunt between the inferior mesenteric vein and the left common iliac vein using a cryopreserved iliac venous graft. The postoperative course was complicated by shunt thrombosis at day 2, probably owing to inadvertent interruption of anticoagulation and a decrease in the shunt flow rate. Surgical thrombectomy was performed successfully. The patient presented no relapse of rectal bleeding and was asymptomatic and well at the 12-month follow-up.
