The patient was a 37 year-old man. We diagnosed Loeys-Dietz syndrome based on his physical characteristics that were widely spaced eyes and brachycephaly etc. Since he developed De Bakey III b aortic dissection 3 months later, he needed surgical repair for saccular-shaped distal arch aortic aneurysm. We performed total aortic arch replacement for the aneurysm and valve-sparing aortic root reconstruction for dilatation of the Valsalva sinus. Furthermore we performed the frozen elephant trunk technique for residual aortic dissection at the same time. After 18 months from the operation, we were able to recognize by computed tomography that the false lumen of the aorta next to the stent graft was thrombosed and absorbed and finally disappeared. The stent graft treatment for patients with connective tissue disease might be an effective method and deserves more attention.
