First-Time Use of a Novel Off-the-Shelf Device for Treating Juxtarenal/Pararenal Hourglass Abdominal Aortic Aneurysms.

backgroundEndovascular aortic repair has become a pivotal treatment for abdominal aortic aneurysms, offering a minimally invasive procedure with low complication rates. However, juxtarenal/pararenal abdominal aortic aneurysms often present challenges given involvement of multiple abdominal visceral arteries, serving as a contraindication to this procedure. CASE SUMMARY: A 61-year-old man presented with an abdominal aortic aneurysm involving the visceral arteries. We performed reconstruction of the superior mesenteric artery and both renal arteries and successfully isolated the abdominal aortic aneurysm using a novel bifurcated stent graft system (Lifetech Scientific). DISCUSSION: This report introduces, for the first time, a novel bifurcated stent graft system designed for the treatment of juxtarenal/pararenal abdominal aortic aneurysm, and proposes a new, safer, simpler, and more effective strategy for the endovascular treatment of these aortic diseases. TAKE-HOME MESSAGES: Pararenal abdominal aortic aneurysms frequently pose unique challenges owing to their involvement of multiple abdominal visceral arteries. This case enables stepwise reconstruction of abdominal visceral arteries using a "building-block" approach.
