Ischemic jejunal stricture in patients with extrahepatic  portal vein obstruction

We report three patients with EHPVO, who developed jejunal strictures due to MVT. They presented with symptoms of proximal bowel obstruction. Two of these patients had evidence of recurrent deep vein thrombosis (DVT), suggesting possibility of an underlying prothrombotic state. One of them had completely occluded bilateral iliac veins and inferior vena cava following DVT, 10 years ago. At the same time, he was identified as having a portal cavernoma. Contrast-enhanced computed tomography showed portal cavernoma together with MVT in all the patients. The thrombus was identified in the jejunal veins in two patients and in the entire superior mesenteric vein up to splenic vein in one patient. All three patients were found to have a tight concentric stricture involving a long length of proximal jejunum. Two patients required urgent s urgical intervention and one died.
