Abstract

A man in his early thirties with complaints of abdominal pain for 1 week was diagnosed with a fusiform, partially thrombosed aneurysm of the superior mesenteric artery (SMA), which was treated with an endovascular stent graft. Three months later, when the patient again presented with abdominal pain, there was an endoleak of type III as detected by computed tomography and digital subtraction angiography. This was treated by in-stent balloon angioplasty with complete resolution of the endoleak. The patient again presented 1 month later with abdominal pain, with a residual sac posterior to the stent, detected on digital subtraction angiography, which was confirmed to be type II endoleak as it was getting filled by one of the jejunal branches of SMA. This was treated by glue embolization of the patent component of the aneurysm after selectively cannulating the branch vessel. This case highlights changing nature of endoleak as a complication of SMA stenting.
