While aneurysm neck length, angulation and width have all been previously assessed in endovascular abdominal aortic aneurysm repair (EVAR), aneurysm neck shape has not been considered.
To analyse the influence of aneurysm neck morphology on outcome following EVAR.
Aneurysm neck morphology in 70 patients undergoing EVAR from April 2001 to May 2004 was determined using pre-operative CT scans and graft plans. Necks were classified as flared, parallel, irregular, conical, barrel or hourglass. End-points were death,Type I endoleak and graft migration.
Forty-six per cent of necks were flared, 34% parallel, 9% irregular, 6% conical, 3% barrel and 3% hourglass. Mean follow-up was 20.2 months (range 4-35). There was one Type I endoleak and one graft migration. There were no aneurysm related deaths.
Assessment of aneurysm neck morphology should be part of the routine preoperative workup for EVAR. A classification system of AAA necks is suggested to facilitate this.
虽然在血管内腹主动脉瘤修复术（EVAR）中，此前已对瘤颈长度、角度和宽度进行了评估，但瘤颈形状尚未得到考虑。
分析瘤颈形态对EVAR术后结局的影响。
使用术前CT扫描和移植物规划确定2001年4月至2004年5月期间接受EVAR的70例患者的瘤颈形态。瘤颈分为喇叭形、平行形、不规则形、圆锥形、桶形或沙漏形。终点指标为死亡、I型内漏和移植物移位。
46%的瘤颈为喇叭形，34%为平行形，9%为不规则形，6%为圆锥形，3%为桶形，3%为沙漏形。平均随访时间为20.2个月（范围4 - 35个月）。发生1例I型内漏和1例移植物移位。无动脉瘤相关死亡。
瘤颈形态评估应成为EVAR术前常规检查的一部分。建议采用一种腹主动脉瘤瘤颈分类系统以促进此项工作。
