Arteriovenous malformation (AVM) is a congenital vascular anomaly with abnormal connection between arteries and veins, bypassing the capillary system. It is widely known in central nervous systems as well as the in the peripheral vascular system such as the gastrointestinal tract. Symptomatic intestinal AVM (I-AVM) may present as gastrointestinal bleeding, ranging from occult bleeding to hematochezia. It can be diagnose depending on severity of symptom, hemodynamic status, location and size of the lesion, either using endoscopy 1 , arteriography 2 or contrast enhanced computed tomography 3 . Treatment may vary on the diagnostic modality use at the time of diagnosis such as endoscopic coagulation/clipping, trans-arterial embolization or intestinal resection. Bleeding I-AVM within the terminal ileum and presenting with a single prominent feeding artery can be managed with palliative ligation and division of feeding artery rather than using bowel resection with the aim of preserving the ileocaecal.Lifetime clinical follow up is necessary for recurrence of bleeding secondary to vessel interconnection via the vasa recta and non-degeneration of AVM nidus.
