Coil Embolization-Assisted Thoracic Endovascular Aortic Repair for Multiple Saccular Descending Aortic Aneurysms with Insufficient Landing Zone.

We report a coil embolization-assisted thoracic endovascular aortic repair technique successfully applied to multiple saccular descending aortic aneurysms in a 74-year-old man. Because of the most distal aneurysm being located at the celiac trunk level and the distance between the superior mesenteric artery and the aneurysm being only 10 mm, a coil embolization of the distal saccular aneurysm was performed before stent delivery to secure a sufficient landing zone. Postoperative computed tomography showed an appropriate positioning of the endovascular devices without endoleak. This coil embolization-assisted technique may extend the indication of the endovascular aortic repair when a saccular aneurysm has an insufficient landing zone.
