目的：动脉瘤腔内修复术（EVAR）后高达20%的患者发生2型内漏，但其长期意义仍存在争议。我们回顾了我们的经验，以评估与2型endoleak.Methods相关的晚期结局：在1994年1月至2005年12月期间，873例患者接受了腹主动脉瘤腔内修复术。计算机断层扫描（CT）扫描评估进行5 mm。研究终点包括总生存率，动脉瘤囊生长，再介入率，转为开放修复术，和腹主动脉瘤（AAA）破裂。术前变量和解剖因素可能与这些endpoints.Results相关进行了评估：我们确定了164例（18.9%）患者早期（在第一次随访CT扫描）2型内漏。平均随访32.6个月。在131例（79.9%）早期2型内漏中，6个月内完全和永久性泄漏消退。应考虑对一过性2型内漏（6个月后消退）进行更频繁的随访或采用更积极的方法进行再干预。
Objective: Type 2 endoleak occurs in up to 20% of patients after endovascular aneurysm repair (EVAR), but its long-term significance is debated. We reviewed our experience to evaluate late outcomes associated with type 2 endoleak.Methods: During the interval January 1994 to December 2005, 873 patients underwent EVAR. Computed tomography (CT) scan assessment was performed 5 mm. Study end points included overall survival, aneurysm sac growth, reintervention rate, conversion to open repair, and abdominal aortic aneurysm (AAA) rupture. Preoperative variables and anatomic factors potentially associated with these endpoints were assessed using multivariate analysis.Results: We identified 164 (18.9%) patients with early (at the first follow-up CT scan) type 2 endoleaks. Mean follow-up was 32.6 months. In 131 (79.9%) early type 2 endoleaks, complete and permanent leak resolution occurred 6 months. Transient type 2 endoleak (those that resolved 6 months) should be considered for more frequent follow-up or a more aggressive approach to reintervention.
