A novel balloon-assisted technique to secure visceral catheterization during a chimney endovascular repair of a ruptured abdominal aortic aneurysm in a centenarian patient

Abstract

A 100-year-old male patient was admitted with a ruptured abdominal aortic aneurysm due to type IA endoleak. Given the proximity of the ruptured site to the superior mesenteric artery (SMA) and renal arteries, a ChEVAR was indicated. Catheterization of the target visceral vessels was a challenging procedural step because of an intensely tortuous thoracic aorta. This hostile aortic anatomy also inhibited exchange for a super stiff guide-wire and selective cannulation with the diagnostic catheter was repeatedly lost when guidewire exchange was attempted. To overcome this issue, a 5 x 40 mm balloon catheter was placed 3cm into the target arteries. The balloon was then inflated below the nominal pressure limit enabling safe exchange for a super stiff guidewire and placement of three 90-cm long 7Fr guiding sheaths. The procedure was thus safely performed with deployment of an aortic extension and the bridging stents.
