Newer generation devices have attempted to accommodate a wider range of aortoiliac anatomies offering endovascular aneurysm repair (EVAR) to more patients with abdominal aortic aneurysms (AAAs). We aim to examine the anatomic suitability for the ultra-low profile Ovation endograft in our AAA patients and to compare them with other contemporary devices.
158 consecutive AAA patients treated with EVAR or open surgical repair (OSR) were tested for EVAR eligibility according to the most commonly used endografts' instructions for use.
106 patients underwent EVAR and 52 OSR. EVAR eligibility was higher for the Ovation system (72%) compared to the rest of the devices (Incraft: 63%, Nellix: 60%, Endurant-II: 59%, Excluder: 55%, Zenith-Flex: 36%, Aorfix: 35%, P-value<0.001). Non-suitable proximal neck anatomy followed by access vessel inadequacy were the primary reasons for ineligibility.
New generation aortic endografts with innovative proximal sealing mechanisms and ultra-low profile delivery systems are increasing patient eligibility for EVAR.
新一代设备试图适应更广泛的主髂动脉解剖结构，从而为更多腹主动脉瘤（AAA）患者提供血管腔内动脉瘤修复术（EVAR）。我们旨在研究超低外形的奥维申（Ovation）腔内移植物在我们的AAA患者中的解剖学适用性，并将其与其他当代设备进行比较。
根据最常用的腔内移植物的使用说明，对158例接受EVAR或开放手术修复（OSR）的连续AAA患者进行了EVAR适用性测试。
106例患者接受了EVAR，52例接受了OSR。与其他设备相比，奥维申系统的EVAR适用性更高（72%）（英克拉夫特（Incraft）：63%，内利克斯（Nellix）：60%，恩杜兰特-II（Endurant-II）：59%，艾克cluder：55%，齐尼思-弗莱克斯（Zenith-Flex）：36%，主动脉固定器（Aorfix）：35%，P值<0.001）。近端颈部解剖结构不合适以及随后的入路血管不足是不符合条件的主要原因。
具有创新近端密封机制和超低外形输送系统的新一代主动脉腔内移植物正在增加患者接受EVAR的适用性。
