主动脉夹层(AD)是一种严重危及患者生命的心血管疾病,病情复杂多变,进展迅速,病死率高。及时、准确、全面的诊断是指导治疗、降低病死率的关键。多层螺旋CT扫描速度快,分辨率高,扫描覆盖范围广,具有重要应用价值,目前已经成为诊断AD最重要的影像学检查方法;经胸超声心动图/经食管超声心动图是合并急性/慢性肾衰竭或对比剂过敏的急性AD可疑患者初次检查的首选方法;磁共振成像适用于部分慢性AD患者的检查。
Aortic dissection (AD) is a cardiovascular disease that seriously endangers the life of the patient. The condition is complicated and changeable, with rapid progress and high mortality rate. Timely, accurate and comprehensive diagnosis is the key to guide treatment and reduce mortality. Multi-slice spiral CT scan speed, high resolution, wide scan coverage, has important application value, has now become the most important diagnostic imaging AD imaging method; transthoracic echocardiography / transesophageal echocardiography is a combination of acute / Chronic renal failure or contrast-sensitive acute AD suspected patients initial examination of the preferred method; magnetic resonance imaging is suitable for some chronic AD patients.
