The acute ischemic leg may be an important clue to the diagnosis of a dissecting aneurysm. Seventeen of 65 patients with dissecting aneurysms presented with this picture. The ischemic leg was often the dominant feature and obscured the correct diagnosis. The possibility of aortic dissection should be considered in any patient with an acutely ischemic leg, especially if there is any accompanying chest, neck, or back discomfort. The presence of an ischemic limb is not necessarily an indication for surgical repair of the dissection itself. Of seven patients treated medically, five survived with limbs intact, and in all five the pulses returned within one month.
急性缺血性下肢可能是诊断夹层动脉瘤的重要线索。65例夹层动脉瘤患者中有17例出现了这种情况。缺血性下肢常常是主要特征，掩盖了正确诊断。任何急性缺血性下肢患者，尤其是伴有胸部、颈部或背部不适者，都应考虑主动脉夹层的可能性。肢体缺血的存在不一定意味着需要对夹层本身进行手术修复。在接受保守治疗的7例患者中，5例存活且肢体完好，所有5例患者的脉搏在1个月内恢复。
