Ruptured chronic type B aortic dissection is conventionally repaired surgically; however, the mortality is high. We report successful use of the candy-plug technique for ruptured chronic type B aortic dissection. A 62-year-old man with ruptured type IIIb dissection was transferred to our hospital as an emergency. Computed tomography angiography showed a dissecting aorta with a patent false lumen, ruptured proximal descending aorta, distal aortic arch entry, and mediastinal hematoma. Debranching endovascular repair with the candy-plug technique achieved occlusion of the false lumen of the ruptured aortic dissection. The patient recovered uneventfully and the false lumen gradually decreased with no endoleak.
