    Abstract:
    Ectopic varices may frequently occur in the rectum in the context of portal hypertension. Although rectal variceal bleeding is not a frequent bleeding situation, it can be life-threatening unless diagnosed and treated immediately. However, there is no specific treatment strategy established so far. We report a case of a man with extrahepatic portal hypertension and severe hematochezia due to rectal variceal bleeding. The patient was diagnosed in the past with portal vein thrombosis, in the context of myelodysplastic syndrome/myeloproliferative neoplasm overlap syndrome, with ectopic varices in the small intestine, colon, rectum and anal canal, peritoneum and perisplenic veins, treated with mesorenal shunt placement and an oral beta-blocker. After the initial stabilization with fluid replacement and red blood cell transfusion, he underwent endoscopic injection sclerotherapy, with no effect on bleeding episodes, while the large size of the varices precluded the option of endoscopic band ligation. Due to the presence of large collateral veins next to the inferior vena cava, the patient underwent combination therapy with Percutaneous Transhepatic Balloon-Assisted Transjugular Intrahepatic Collateral Caval shunt placement, to decompress portal pressure, followed by angiographic embolization of the feeding vessels resulting in successful hemostasis. Hematochezia ceased, hemoglobin was stabilized and the patient was safely discharged from the hospital. Controlling and treating rectal varices can be a challenging task indicating the need of a multidisciplinary approach. In the absence of well-established treatment guidelines for rectal varices, we highly recommend treatment of refractory ectopic variceal bleeding, non-responsive to endoscopic treatments, with portocaval shunt placement in combination with embolization.
