Contrast-Enhanced Sonographic Follow-up After Stenting of Visceral Artery Aneurysms

We report 2 cases of exclusion of visceral artery aneurysms. The first was a common hepatic artery aneurysm treated with a multilayer stent; the second was a celiac trunk aneurysm excluded by a covered stent. Computed tomographic angiography was performed at regular intervals after each procedure, together with echo color Doppler imaging and contrast-enhanced sonography. Computed tomographic angiography and contrast-enhanced sonography were able to detect endoleaks in both patients and the related inflow vessel; moreover, diameter measurements of the sacs were identical. In our preliminary experience, contrast-enhanced sonography appeared to be as accurate as computed tomographic angiography after endovascular visceral artery aneurysm exclusion.
