Visceral artery aneurysms: evaluation using 3D contrast-enhanced MR angiography.

Abstract

Visceral artery aneurysms are uncommon, but they are clinically important because of the high incidence of rupture and life-threatening hemorrhage. Visceral artery aneurysms in patients with vascular anatomic variations are extremely rare, but detecting these variations is significant in this setting to determine the best treatment strategy; therefore, a thorough assessment of the aneurysm and of the vascular anatomy before treatment is paramount. Three-dimensional contrast-enhanced MR angiography is a noninvasive technique for the diagnosis and display of visceral artery aneurysms. It can provide 3D anatomic information that is needed for surgery or embolization.
