: To evaluate the clinical utility of the coil in plug (CIP) method in internal iliac artery (IIA) embolization during endovascular aortic aneurysm repair (EVAR) compared to conventional coil embolization (CCE). : From July to December 2018, 10 patients who underwent IIA embolization during EVAR were divided into CIP (n=5) and CCE (n=5) groups. In the CIP technique, the AVP-1 with a size more than 30%-50% of that of the embolized IIA diameter was used. The AVP-1 was deployed in the IIA. Before detachment of the AVP-1, a 2.2-F micro catheter was inserted through the 6-F delivery guiding sheath, and entered the plug. The AVP-1 was then packed with hydrogel micro coils. We compared number of coils used, embolization length, embolization time, volume embolization ratio, and embolic material cost between the groups. : The CIP method achieved shorter embolization length with fewer coils used compared to CCE. The CIP method decreased the cost of total embolic materials. : The CIP method can achieve shorter embolization length with fewer coils used compared to CCE.
为评估在血管腔内主动脉瘤修复术（EVAR）期间，与传统弹簧圈栓塞术（CCE）相比，栓塞器在髂内动脉（IIA）栓塞中的临床效用。从2018年7月至12月，10例在EVAR期间接受IIA栓塞的患者被分为栓塞器在栓塞物内（CIP）组（n = 5）和CCE组（n = 5）。在CIP技术中，使用尺寸大于被栓塞的IIA直径的30%-50%的AVP-1。将AVP-1部署在IIA中。在AVP-1脱离之前，通过6F输送引导鞘插入一根2.2F微导管，并进入栓塞器。然后用凝胶微弹簧圈填充AVP-1。我们比较了两组之间使用的弹簧圈数量、栓塞长度、栓塞时间、容积栓塞率和栓塞材料成本。与CCE相比，CIP方法使用更少的弹簧圈实现了更短的栓塞长度。CIP方法降低了总栓塞材料的成本。与CCE相比，CIP方法可以使用更少的弹簧圈实现更短的栓塞长度。
