[Chronic arterial mesenteric ischemia: Doppler color ultrasonography demonstration of collateral flow]. / Ischémie mésentérique chronique d'origine artérielle: mise en évidence de réseaux de vicariance par échographie Doppler couleur.

ABSTRACT

Two cases of atypical mesenteric ischemia where color Doppler US demonstration of the underlying arterial abnormality and collateral supply was possible are presented. Significant stenosis of the celiac axis and thrombosis of the SMA were clearly depicted, along with the presence of collateral arterial supply. Endovascular treatment was successful in both cases. These cases confirm the possibility of detecting collateral flow at Doppler imaging in patients with mesenteric ischemia, both for diagnosis of mesenteric ischemia and endovascular treatment planning.
