Spontaneous visceral artery dissection without aortic dissection is rarely encountered. Furthermore, there is no consensus regarding the pathology or optimal therapy related to this problem. This report details six cases of isolated visceral artery dissection. Patients evaluated included five men and one woman with a mean age of 51 years. Of these cases, three presented with celiac artery (CA) dissection, two presented with superior mesenteric artery (SMA) dissection, and one presented with CA, SMA, and bilateral renal artery (RA) dissection. All patients complained of severe abdominal pain and were diagnosed by contrast-enhanced computed tomography. All cases received conservative treatment including antihypertensive therapy. Among the six patients, four were hospitalized and the other two were treated at an outpatient clinic. No patients developed organ ischemia or aneurysm enlargement during follow-up.
