True and false aneurysms in Behçet's disease: case report with ultrastructural observations

One of the most important aspects of Behçet's disease is aneurysmal arteriopathy. The major problem of this complication is its tendency to develop recurrent false aneurysms at anastomotic and traumatic sites, such as angiographic punctures. We present a clinical case in which five aneurysms, some true, some false, were operated on during a period of 6 years, with the aid of ultrastructural observations of the wall of a true and a false aneurysm. One of the true aneurysms, localized in the aorta, was treated by direct aneurysmorrhaphy, and the 6-year follow-up demonstrated the absence of recurrences. Based on both this experience and the data in the literature, we suggest that the most appropriate surgical approach would, when possible, be direct aneurysmorrhaphy.
