COOK-ZFEN定制开孔型血管内支架系统治疗短瘤颈腹主动脉瘤的近期疗效

Short term result of COOK-ZFEN custom-made endovascular stent graft system for the treatment of short-neck abdominal aortic aneurysm

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定制支架标准纳人的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)mnl,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。

Objective 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 typeⅡendoleak and 1 patient with typeⅢendoleak.The endoleaks disappeared in 4 patients during follow-up of 312 months.1 patient suffered with typeⅡand typeⅢndoleak,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.
