Purpose: To describe the candy-plug technique using an Excluder aortic extender for distal occlusion of a large false lumen aneurysm in chronic aortic dissection.Technique: A 60-year-old female patient with a history of chronic type B aortic dissection and high-dose steroid use for Churg-Strauss syndrome developed a large 6.2 cm maximum diameter false lumen aneurysm. She underwent thoracic endovascular aortic repair from the left common carotid artery to the descending aorta to cover the proximal entry at the level of distal arch, with coil embolization of the left subclavian artery. To occlude the large false lumen from the reentry just below the level of the left renal artery ostium, a modified 32×45-mm Excluder aortic extender was deployed in the false lumen through the reentry, and a 16-mm Amplatzer Vascular Plug I was deployed in the waist of the modified Excluder aortic extender for complete occlusion. No obvious technical complication was seen. Contrast-enhanced computed tomography at 1 and 14 months revealed no endoleaks and showed complete false lumen thrombosis.Conclusion: The candy-plug technique using the Excluder aortic extender is feasible for occlusion of a large false lumen aneurysm in chronic aortic dissection.
