Abstract

An aneurysm is defined as a focal dilatation of all three walls of an artery wall. This can occur at any point in the arterial tree but most commonly presents as an abdominal aortic aneurysm (AAA), with a diameter of 50% greater than its normal size. The prevalence of AAAs is estimated to be between 1.2-7.6% in over 50 year olds in the UK, and it is sevenfold higher for men compared with women1. There is approximately a 1% mortality from ruptured AAAs, and as such current NHS guidelines recommend that all men over 65 are screened annually, a precedent supported by the Multicentre Aneurysm Screening Study (MASS)2. AAAs reaching 5.5cm in diameter require elective surgical repair, which can take the form of endovascular aneurysm repair (EVAR) or open surgical repair.
评价采用开窗EVAR选择性治疗复杂AAA的决定
动脉瘤被定义为动脉三壁的局灶性扩张。这可以发生在动脉树的任何一点,但最常见的表现是腹主动脉瘤(AAA),直径比正常大小大50%。据估计,英国50岁以上人群中AAAs的患病率在1.2-7.6%之间,男性的患病率是女性的7倍1。动脉瘤破裂的死亡率约为1%,因此,目前的NHS指南建议所有65岁以上的男性每年进行筛查,这是多中心动脉瘤筛查研究(MASS)支持的先例2。直径达到5.5cm的AAAs需要选择性手术修复,可以采取血管内动脉瘤修复(EVAR)或开放性手术修复。
