title: [Isolated spontaneous dissection of visceral arteries].
abstract: 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. Both dissections were short and had patent saccular false lumens and reduced caliber of the true lumens. This morphological type is one of the most uncommon within this rare entity. However, in recent years, the number of cases published is rising. This suggests that this entity may have been underdiagnosed before the widespread use of multidetector CT. We discuss the two morphological classifications of dissection of the visceral arteries and the need to adapt therapeutic management to the particular circumstances of each case.
