Gastrointestinal angiodysplasia (GIAD) represents one of the most frequent causes of recurrent lower gastrointestinal bleeding in the elder population. Clinical manifestations are highly variable, diagnosis is done with colonoscopy or CT and management consists of either endoscopic or, more conservatively, endovascular approach. Trans-arterial embolization (TAE) reduces blood flow into the lesion and may complicate with perforation, dissection, vasospasm and bowel ischaemia. To date, coils and Gelfoam represent the most employed embolizing agents, followed by PVA and onyx. We report the successful embolization of GIADs in four patients with n-butyl 2-cyanoacrylate (NBCA) and Lipiodol Ultra-Fluid (LUF): despite the reported higher risk of bowel infarction when compared with the other agents, no major complication or short-term recurrence occurred in our series.
