目的：对于大于14 mm的扩张的髂总动脉，大多数用于腔内AAA修复的移植物不能达到足够的止血效果。将自体移植物延伸至髂外动脉可以缓解这一问题，但需要牺牲髂内动脉。我们使用了较大直径的主动脉延长袖带，以便在扩张的、非瘤性的髂总动脉患者中获得足够的移植物与动脉壁的对接。由于由此产生的髂骨四肢张开的结构，这项技术被称为钟底。然而，尚不清楚这些扩张的髂总动脉随后是否会扩大，从而导致内漏或移植物移植物。方法：回顾了在我所接受腔内腹主动脉瘤修补术的96例患者的记录。14名患者被确定为将主动脉延长袖带放置在18个扩张型(>；14 mm)内，但
Purpose: Most endografts for an endoluminal AAA repair cannot achieve an adequate hemostatic seal in ectatic common iliac arteries larger than 14 mm. The extension of the endograft into the external iliac artery can alleviate this problem but requires sacrifice of the internal iliac artery. We have used the larger diameter aortic extension cuff to obtain adequate endograft to arterial wall apposition in patients with ectatic, nonaneurysmal common iliac arteries. Because of the resultant flared configuration of the iliac limb, the technique is termed bell-bottom. However, it is unknown whether subsequent enlargement of these ectatic common iliac arteries that will lead to endoleaks or endograft migration will occur.Methods: The records of all 96 patients who have undergone endoluminal abdominal aortic aneurysm repair at our institution were reviewed. Fourteen patients were identified in whom aortic extension cuffs were placed into 18 ectatic (>14 mm, but
