| [ Summary ] |
Although vascular lesions in the small intestine account for bleeding sources in a large percentage of patients with Mid-GI-bleeding, they observed by endoscopy vary, and their terms and clinical strategies have not been standardized. There are three pathological conditions of vascular lesions. Angioectasia is characterized by venous/capillary lesions, Dieulafoy's lesions are characterized by arterial lesions, and arteriovenous malformation is a condition in which arteries and veins are directly connected without capillary beds. We classified vascular lesions in consideration of the presence or absence of pulsatility. The presence or absence of arterial components provides important information for the understanding of pathological conditions. This classification will be useful for selecting hemostatic procedures and performing outcome studies. |
