We present the case of a 56-year-old man who had undergone a total debranched TEVAR for a distal arch aneurysm in an other hospital 7 years eariler. One year after the surgery, a graft infection occurred and the left subclavian artery graft was removed and an axillo-axillary bypass was done. However, the infection persisted and two cutaneous fistulae at the left neck and median sternotomy were recognized. Preoperative FDG-PET CT revealed a high uptake of FDG in the left common carotid artery graft, the stent graft in the ascending aorta, and the left neck wound and median sternotomy site. After we exposed the left common carotid artery, the left chest was entered through a posterolateral thoracotomy. The cardiopulmonary bypass was initiated by cannulating the left common femoral vessels and main pulmonary artery, and core cooling was done to 23℃. The descending aorta was clamped at the Th10 level, and the proximal descending aorta to arch was opened to remove the infected stent graft. Selective antegrade cerebral perfusion was started and antegrade cardioplegia was given. The ascending-arch-descending aorta was replaced with a rifampicin-soaked Dacron graft, followed by left common carotid artery reconstruction using an 8 mm Gore-Tex graft. The new graft was wrapped with a pedicled omental flap. Postoperative antibiotic therapy was continued for 6 weeks and the fistulae were surgically closed. The patient was discharged and is back to the normal life.

A 47-year-old woman was incidentally found to have a thoracic aortic aneurysm by CT scan. There was an aneurysm in the ascending aorta and aortic arch, and the Valsalva sinus was enlarged. Echocardiography showed a severe aortic regurgitation. Valve-sparing aortic root replacement and total arch replacement was performed. The pathology of the ascending aorta was consistent with giant cell arteritis. Her postoperative course was straightforward, and she was discharged 23 days after surgery. In Japan, there are few reports of valve-sparing surgery for patients with giant cell aortitis, and we report our experience of a rare case.

A 35-year-old man was referred to our hospital for surgical repair of grade IV/IV aortic regurgitation secondary to a congenital unicuspid aortic valve accompanied by aneurysm of the ascending aorta. The aortic valve was the unicuspid unicommissural type and a fully developed commissure was located in the left lateral position (left coronary/right coronary). The anterior (non-coronary/right coronary) and posterior (non-coronary/left coronary) borders were rudimentary with calcified raphe. We performed aortic valve repair in combination with valve sparing root replacement (reimplantation) and partial arch replacement. We converted the unicuspid into a bicuspid aortic valve by preserving his own free margin tissue and creating a neocommissure to the 180 degrees opposite side of the left lateral commissure at the same height by enlarging the cusp with a glutaraldehyde-treated autologous pericardium patch to the cusp belly. The patient was discharged on the 17th postoperative day with trace aortic regurgitation. We successfully repaired the unicuspid aortic valve by augmenting the cusp size using a pericardium patch in order to preserve the free margin of the cusp.

The patient was a 15-month-old girl with Down's syndrome. She had a heart murmur on the first day after birth. The echocardiogram revealed that she had the tetralogy of Fallot (TOF) and mitral insufficiency (MI). She was observed because she had no heart failure or cyanosis. However, she developed heart failure with progressive MI. Then, she was admitted to our medical center for surgical treatment. During the operation, it was confirmed that the primary septum was intact and a large ventricular septal defect was located at the inlet to outlet portion with anterior malalignment. Each leaflet of the atrioventricular valve were attached to the same level and the ventricular septum was scooped out. TOF with endocardial cushion defect (ECD) without primary septal defect was diagnosed based on the operative findings. Surgical repair was performed through the right atrium and pulmonary artery. She was discharged 17 days after operation without any complications. This was a very rare combination of TOF with ECD without a primary septal defect. We discussed this rare condition with a review of the literature.

Subclavian arterial aneurysms are relatively rare compared to aortic aneurysms. The common causes of subclavian arterial aneurysms are arteriosclerosis, non-specific inflammation, thoracic outlet syndrome, and trauma. A case of a subclavian arterial aneurysm is reported. The patient was a 57-year-old woman. She had no previous history of hypertension, infection and trauma. She underwent complete resection of the aneurysm and reconstruction of right subclavian artery. Exploration of the aneurysmal wall revealed circumferential ridge which caused stenosis of the right subclavian artery at the orifice of the aneurysm. It has been suggested that a subclavian arterial aneurysm developed as a result of abnormal development of the embryologic right fourth and distal sixth aortic arches.
