| Background : Aortic dissection limited to the abdominal aorta is a rare clinical entity with non-specific clinical features. Optimal treatment, as well as natural history and progression of the disease, remain unclear. In 1992 we reported 5 cases of isolated abdominal aortic dissection (IAAD) and in the present paper we update our series with 5 additional patients. A concise literature review is also provided. Methods : Between 1992 and 2014, we diagnosed 5 patients with IAAD (4 men, mean age 60.6 years, range 45-77). No patient presented with acute onset of symptoms. One patient was diagnosed with a periumbilical bruit, and diagnosis was made with magnetic resonance (MR)-angiography. Other diagnoses were incidental findings on computed tomographic (CT) scanning. Dissection was located infrarenally in four cases and at the celiac trunk in one case. Results : All cases were treated conservatively with hypertension control and close follow-up. Follow-up period ranged from 10 months to 20 years and was performed yearly by CT- or MR-angiography and blood pressure monitoring. All patients remained symptom-free, all dissection lengths remained stable. Slowly increasing post-dissection aneurysmal dilatation was encountered in two patients. We combined results of these five new patients with five previously diagnosed and reported patients at our center. Treatment was surgical in only one out of 10 patients. There was no disease-related mortality during follow-up. Conclusions : Based on our case series, IAAD remains a rare clinical condition with relative benign clinical course. Treatment was almost exclusively conservative. Recent publications state IAAD might be underrecognized and under-diagnosed compared to thoracic aortic dissections. |
