title: ["Pseudo-dissection" in an abdominal aortic aneurysm].
abstract: Sonography of 52 patients with aneurysms of the abdominal aorta revealed in 7 cases hypoechoic crescent-like zone between parietal thrombus and the aortic wall which simulated aortic dissection. Duplex-sonography was performed in all cases and no flow could be detected in this area. In two patients intraoperatively several milliliters of a serous fluid could be aspirated from this zone which confirmed the suggestion of seroma within the parietal thrombus. This observation may be found rather frequently and should not be a reason for immediate surgery.
