目的报道一种新型无膜支架在主动脉瘤治疗中的应用。病例报告1例81岁男性合并多发性腹主动脉瘤合并63 mm肾旁腹主动脉瘤，采用28×100 mm多层血流调节支架治疗。即刻，透视显示动脉瘤囊内血流速度减慢。支架覆盖的所有主动脉分支(腹主动脉干、肠系膜上动脉和肾动脉)均保持通畅。12个月后的连续计算机断层扫描显示支架和内脏动脉开通良好，囊直径(58 Mm)和体积(84.9 cm~82.8 cm~3)逐渐缩小。结论无覆膜多层支架的使用减少了动脉瘤的血流，但保留了分支动脉的血流，这是覆膜支架所不能做到的。
Purpose To report the use of a new type of uncovered stent to treat aortic aneurysms. Case Report Under compassionate use, an 81-year-old man with multiple comorbidities and an expanding 63-mm juxtarenal abdominal aortic aneurysm was treated with a 28×100-mm Multilayer flow-modulating stent. Immediately, the blood flow velocity inside the aneurysm sac appeared reduced on fluoroscopy. All aortic branches covered by the stent (celiac trunk, superior mesenteric artery, and renal arteries) remained patent. Serial computed tomography at up to 12 months has shown excellent stent and visceral artery patency and progressive reduction in the sac diameter (58 mm) and volume (84.9 cm3 to 82.8 cm3). Conclusion This case shows that the use of an uncovered multilayer stent reduces the flow in the aneurysm but preserves perfusion of the branch arteries, which is impossible with covered stents.
