[Vascular malformations of the cecum: treatment by embolization. Apropos of 2 cases].

Two cases of arteriovenous malformations of the cecum treated by transcatheter embolization are presented. In both cases, treatment resulted in improvement of the clinical and biological signs. In general, there is a high risk of ischemic complications associated with this treatment. Embolization of arteriovenous malformations should be considered rarely and in the following cases: single lesion, high blood output, feasibility of superselective catheterization. The risk of colonic ischemia calls for preparation of the colon as if the patient were undergoing colonic surgery, as well as thorough clinical follow-up (for at least 10 days).
