Abstract
Hematochezia is a rare clinical presentation of congenital extrahepatic portosystemic shunt (CEPS). We describe a series of three patients with type II CEPS presenting as hematochezia that were treated by catheter embolization, followed by a brief review of published articles. Hematochezia of the patients was due to the giant inferior mesenteric vein, superior rectal vein and colonic varices. The catheter embolization was successfully accomplished in all of the patients. After a mean follow-up of 27 months, no serious adverse effects were observed. For unexplained massive hematochezia, CEPS needs to be considered as a differential diagnosis. Based on our present results and the review of the literature, transcatheter permanent embolization of the giant inferior mesenteric vein might be an effective and safe treatment for type II CEPS.
Level of Evidence Level 4, case series.
