Celiac Artery Aneurysm With Dissection

A 52-year-old male with no history of vascular disease presented with a celiac artery aneurysm. Incidentally, a celiac artery dissection was discovered. The dissection was a result of the aneurysm. The proximal abdominal aorta, celiac artery, and superior mesenteric artery were examined with gray scale, color flow, and spectral Doppler. The proximal abdominal aorta, celiac artery, and superior mesenteric artery were without evidence of atherosclerotic plaque. There was evidence of a celiac artery aneurysm measuring 1.3 cm, which was stable compared with a previous CT (computed tomography) from April 2014. A dissection was visualized within the celiac artery with color flow aliasing and higher velocities visualized in the false lumen, with the highest measuring 402/142 cm/s. The true lumen highest velocity measured 209/56 cm/s. The superior mesenteric artery was patent with normal flow patterns and velocities measuring from 134 to 189 cm/s. Celiac artery aneurysms and dissections are extremely rare and can be difficult to find and treat. By scanning the aneurysm, the dissection could be found, perhaps reducing the risk of embolus or occlusion
