[Open stent implantation for ascending aorta aneurysm with severe calcification].

A 77-year-old woman had an ascending aortic aneurysm and aortic regurgitation due to aortitis syndrome. Computed tomography showed that ascending aorta was 55 mm in diameter and had severe calcification between the ascending aorta and distal aortic arch involves neck vessels. We performed open stent implantation and aortic valve replacement with bioprostheses valve. No adverse event occurred after the operation and the patient was discharged on the 28th postoperative day. The open stent implantation was useful for the treatment of the aneurysm in high risk patients.
