Abstract

Triple barreled dissection is an extremely rare form of aortic dissection with only a few cases reported in the literature. It is characterized by 3 lumens separated by 2 intimal flaps, resembling the appearance of the \'Mercedes Benz\' sign. We present an unusual case of triple barreled aortic dissection in a 71-year-old patient with history of hypertension. Chest radiography showed a widened mediastinum. The CT images showed a thoraco-abdominal type B aortic dissection with three lumens giving the appearance of the \'Mercedes Benz\' sign. As the CT-scan showed no complications of the aortic dissection, the patient received medical conservative treatment.

摘要

三管夹层是一种极为罕见的主动脉夹层，文献中仅报道了少数病例。它的特点是由2个内膜瓣分开的3个管腔，类似于“奔驰”标志的外观。我们介绍了一名71岁有高血压病史的三管主动脉夹层的罕见病例。胸部X线检查显示纵隔增宽。CT图像显示胸腹B型主动脉夹层，具有三个管腔，具有“梅赛德斯奔驰”标志的外观。由于CT扫描显示无主动脉夹层并发症,患者接受内科保守治疗。
