摘要目的:评估COOK-ZFEN定制支架治疗短瘤颈腹主动脉瘤的安全性及有效性。方法:回顾性分析复旦大学附属中山医院2018年3月至2019年9月按短瘤颈腹主动脉瘤及COOK-ZFEN定制支架标准纳入的5例接受开窗式覆膜支架腔内隔绝术的临床资料。结果:5例短瘤颈腹主动脉瘤患者，年龄（69±11）岁，开窗支架定制时间4~6周，腹主动脉瘤最大直径（60.8±14.0） mm，平均肾下瘤颈直径（26.0±2.6） mm，平均锚定区长度（6.4±2.2） mm。技术成功率100%，中位随访时间6.8个月。术中无内脏血管丢失及支架移位，围手术期无死亡，无其他重大并发症。内漏情况：单纯Ⅱ型内漏3例，少量单纯Ⅲ型内漏1例，4例患者随访过程中内漏消失，1例合并Ⅱ型漏和Ⅲ型漏，所有患者内脏血管及分支支架均通畅。结论:定制开窗支架治疗短瘤颈腹主动脉瘤是安全可行的，中长期疗效需要进一步随访。

abstractsObjective:To evaluate the safety and efficacy of a Zenith fenestrated aortic stent-graft (ZFEN) system in the treatment of short-necked aneurysms.Methods:The clinical data of 5 patients receiving F-EVAR in Zhongshan Hospital, Fudan University from Mar 2018 to Sep 2019 according to the standards of short-necked abdominal aortic aneurysm and COOK ZFEN custom stent were retrospectively analyzed.Results:Patients' average age was (69±11) years old. The time of stent customization was 4-6 weeks. The average maximum diameter of AAA was (60.8±14.0) mm. The average proximal neck diameter was (26.0±2.6) mm and the average length anchoring zone was (6.4±2.2) mm. The rate of technical success was 100%. There was no intraoperative loss of visceral vessels and stent displacement. The meane follow-up time was 6.8 months. The perioperative mortality was 0, and there were no other major complications. There were 3 patients with simple type Ⅱ endoleak and 1 patient with type Ⅲ endoleak. The endoleaks disappeared in 4 patients during follow-up of 3-12 months. 1 patient suffered with type Ⅱ and type Ⅲ endoleak, and the visceral vessels and branching stents were patent in all patients.Conclusion:The short term result of COOK ZFEN stent-graft system was safe and feasible for the treatment of short-necked AAA.
