孤立性腹主动脉夹层（IAAD）属临床少见病，其原发破口位于腹主动脉，可分为自发性、外伤性和医源性。 IAAD 的高危因素为男性、高血压和合并主动脉瘤，发病时多表现为腹痛、背部疼痛等。IAAD 的治疗 方式包括药物治疗、传统开放手术、腔内修复术和杂交手术，近年来腔内修复术逐渐成为治疗的首选， 笔者对IAAD 的临床特点和治疗进展进行综述。
Isolated abdominal aortic dissection: clinical features and treatment progress
Isolated abdominal aortic dissection (IAAD) is a rare condition with the primary entry tear located in the abdominal aorta, which might occur spontaneously, or be the consequence of trauma and iatrogenic events as well. Male, hypertension and concomitant aortic aneurysm may be high risk factors for IAAD. The frequent presentations at onset are abdominal pain, back pain, and intermittent claudication. Therapeutic choices for IAAD include medical treatment, conventional open surgical repair, endovascular repair and hybrid surgery. Recently, endovascular repair has increasingly become the most preferred treatment option. In this article, the authors address the clinical features and management advances of IAAD.
