Abstract

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.
