    Abstract Objectives: Treatment of thoracoabdominal aortic aneurysms in high surgical risk patients can be challenging. Reports of physician-modified inner-branched endovascular repair (PMiBEVAR) are increasing. Despite low morbidity and mortality rates, re-interventions for endoleaks with these grafts are serious. There are no reports of additional treatment for PMiBEVAR failure.
    Methods/results: A 75-year-old man presented to our hospital with a Crawford's type IV thoracoabdominal aortic aneurysm. A PMiBEVAR was performed. Postoperative computed tomographic angiography revealed an endoleak from the inner branch of the right renal artery. A re-intervention was performed with coil embolization of the endoleak. Imaging after re-intervention showed successful obliteration of the endoleak.
    Conclusions: We thereby report a successful case of re-intervention for PMiBEVAR failure.

    Abstract A 66-year-old man with a history of type 2 diabetes mellitus who was undergoing hemodialysis presented with angina. Coronary angiography revealed triple-vessel coronary artery disease. He underwent multiple percutaneous coronary interventions due to recurrent restenosis and was referred for coronary artery bypass grafting (CABG). The left internal thoracic artery and bilateral saphenous veins were harvested under general anesthesia. Four CABGs were performed: left internal thoracic artery to the left anterior descending artery; saphenous vein graft to the obtuse marginal branch of the circumflex artery; and saphenous vein graft to two sites in the right coronary artery. Intraoperative assessment with transit-time flow measurements showed no abnormalities, and the surgery was completed. On postoperative day seven, coronary and graft angiography revealed dissection of the left internal thoracic artery at its midportion with restricted flow. On postoperative day eight, a surgical intervention was performed to excise the dissected segment of the left internal thoracic artery. The dissection site was identified by fluorescence imaging. The dissected segment was excised, and the artery was re-anastomosed. The postoperative course was uneventful, and graft angiography performed on postoperative day 22 confirmed good blood flow. Fluorescence imaging was valuable in identifying the dissection site in the left internal thoracic artery.

    Abstract A 77-year-old male patient with immunoglobulin (Ig)G4-related disease was diagnosed with a 60-mm aortic arch aneurysm and atherosclerosis of the aorta advanced throughout the body. Aortic arch replacement surgery was performed with circulatory arrest at 28°C. One week later, the patient developed acute pancreatitis, followed by encapsulated necrosis in the chronic phase. After debridement surgery, the patient's condition improved.

    Abstract Background: After a median sternotomy, mediastinitis may develop, necessitating reopening of the chest. Rarely, reoperation due to hematoma after cardiovascular surgery is experienced. In the present case, we experienced a patient who initially had mediastinitis, but later developed a chronic hematoma and underwent multiple surgeries.
    Case presentation: The patient was a 40-year-old man who underwent aortic valve replacement for a bicuspid aortic valve and a graft for a dilated ascending aorta. Postoperatively, he developed hematoma in the anterior mediastinum on multiple occasions with repeated episodes of infection that required multiple median sternotomies.
    Conclusions: We reported our experience with a rare case of multiple median sternotomies. In the early stage, mediastinitis due to infection was observed, and in the late stage, mediastinal dilatation due to hemorrhage was observed.

    Abstract We present a case of an 82-year-old male patient with a history of severe mitral regurgitation, severe aortic regurgitation, chronic atrial fibrillation, and suicide attempts due to depression. The patient underwent mitral valvuloplasty and aortic valve replacement for mitral valve regurgitation and aortic valve regurgitation. The patient was extubated on the morning of the sixth postoperative day, but he was reintubated in the evening because of hypotension and an unstable respiratory status. Echocardiography revealed Takotsubo cardiomyopathy development, and the patient was treated with intra-aortic balloon pump (IABP) implantation, which was removed on postoperative day 11.

    Abstract Background: Stent graft-induced new entry (SINE), defined as the stent graft-induced formation of a new entry point for blood to enter an area, is increasingly being observed after thoracic endovascular aortic repair (TEVAR) for Stanford type B aortic dissection worldwide. We herein describe a case of Stanford type A aortic dissection due to proximal SINE after TEVAR for Stanford type B dissection.
    Case presentation: This case involved a 58-year-old man with type A aortic dissection due to SINE. Six years previously, he had developed severe back pain and was diagnosed with type B aortic dissection after computed tomography examination. Because the primary entry was positioned at the descending aorta, we conducted TEVAR for exclusion of the entry with a GORE TAG conformable thoracic aortic graft. He was thereafter followed by our hospital. Six years later, he developed jaw pain and was examined at another hospital. He was transferred to our hospital because of the possibility of type A dissection. Computed tomography revealed type A aortic dissection with proximal site SINE. Emergency partial arch replacement was conducted, and he was discharged on postoperative day 27. Because the entry was at the lesser curve of the arch, we excluded the entry and conducted partial arch replacement.
    Conclusions: In this case, proximal SINE occurred 6 years after TEVAR. Because SINE may occur even in the long term after TEVAR, careful follow-up is necessary.

    Abstract A 46-year-old male developed a Stanford type B aortic dissection. At age 48, he underwent left open thoracic descending aorta replacement because of the enlargement of the descending thoracic aorta. At 51 years old, he underwent abdominal aorta replacement because of ischemia in the right lower extremity and the enlargement of an abdominal aortic aneurysm. The septum between the true and false lumens was submitted to histopathological examination, which revealed bilateral intimal tissue with the tunica media lying in between.

    Abstract A 74-year-old man with pemphigoid, for which he was on a daily regimen of 14 mg of prednisolone and immunosuppressive drugs, was admitted to the orthopedic surgery department with a fever of 38 °C. An MRI scan of his head revealed multiple bilateral cerebral infarcts, and echocardiography showed a 30-mm structure attached to the anterior apex of the mitral valve. The patient was diagnosed with infective endocarditis and administered antibiotic therapy. Five days after the diagnosis, the patient underwent mitral valve surgery, during which the mitral valve was observed to be severely deteriorated and hence replaced with a bioprosthetic valve. Blood flow disturbance was observed in the right lower extremity, and a thrombectomy was performed. A dispersed vegetation around the heart was observed and removed. After the surgery, the patient progressed without mediastinitis and had a good postoperative course. He was discharged from the hospital on the 56th postoperative day after continued antibiotic therapy.
