Objectives Chronic disseminated intravascular coagulation is a rare complication of aortic dissection, and its optimal treatment remains controversial. Methods We present a 78-year-old man with repeated hemorrhagic events by disseminated intravascular coagulation due to chronic aortic dissection treated by thoracic endovascular aortic repair. Results Computed tomography angiography at three months revealed a completely thrombosed false lumen from the distal aortic arch to the descending aorta at the celiac artery level. Platelets and D-dimer levels remained stable, and the patient was doing well without hemorrhagic complications. Conclusions Endovascular repair was effective for disseminated intravascular coagulation due to chronic type B aortic dissection.
