孤立性髂动脉瘤的病因分析及其治疗进展

Etiological analysis and treatment progress of isolated iliac artery aneurysm

孤立性髂动脉瘤(ⅡAA)最早报道于19世纪20年代,是指局限在髂动脉部位的动脉扩张性疾病,包括单侧或(和)双侧髂总、髂外和髂内动脉瘤,其中髂总动脉瘤占70%~90%,髂内动脉瘤占10%~30%,髂外动脉极少受累。ⅡAA在临床极其罕见,发病率仅为0.1%~9%,发病原因尚不明确。ⅡAA临床表现比较隐匿,疾病预后差,动脉瘤破裂大出血是导致患者死亡的主要原因。本文将结合ⅡAA的病因、临床特点、诊断及其国内外最新治疗进展作如下综述。

Isolated iliac artery aneurysm （IIAA）,firstly reported in the 1820s,refers to a dilated artery disease limited in the iliac artery,and includes unilateral and/or bilateral common, external and internal iliac artery aneurysms, among which common iliac aneurysms account for 70% to 90%, internal ones for 10% to 30%, while external iliac artery rarely involved. IIAA is very rare clinically,with a prevalence of only 0.1% to 0.9%,and its etiology remains unclear. In clinical practice,it has occult manifestations and poor prognosis, and aneurysm rupture bleeding is the leading cause of death. This article reviewed the progress of IIAA in combination of its clinical characteristics,etiology,diagnosis and treatment.
