Disección aislada y espontánea de arterias viscerales

We present the cases of two men with isolated spontaneous dissection of visceral arteries diagnosed by multidetector CT. In the first patient, dissection of the celiac trunk was associated with periarterial changes. In the second patient, dissection of the superior mesenteric artery was associated with stenosis at the root of the celiac trunk. Both patients presented with acute pain, which was more intense and longer lasting in the first patient. Aortic dissection was suspected clinically in both patients.
