A 74-year old man, presented with dyspnea following acute abdominal pain, was admitted to an initial hospital. The plain computed tomography (CT) scan revealed a ruptured abdominal aortic aneurysm (AAA). Emergency insertion of intra-aortic balloon occlusion (IABO) catheter was carried out due to his unstable hemodynamic condition. The patient was transferred to our hospital after surgical consultation. Open surgical repair was carried out, and massive retroperitoneal hematoma and excessive bowel edema made it difficult to close the abdomen primarily. Delayed closure following Open Abdomen Management (OAM) was effective.

A 54-year-old man with ischemic mitral regurgitation underwent surgical ventricular restoration, mitral valve plasty and a coronary artery bypass. A chest X-ray 7 days later revealed pleural effusion on the right side. A chest tube was inserted and about 1,000 ml of fluid was drained. However, re-expansion pulmonary edema (RPE) occurred 2 h later. Positive pressure ventilation and intravenous infusion with a diuretic improved the RPE. He was resuscitated on the following day to receive percutaneous cardiopulmonary support (PCPS) for unstable hypoxemia and hypotension. Oxygenation improved, PCPS was withdrawn 2 days later, and the endotracheal tube was removed. Re-expansion pulmonard. He was resuscitated on the following day to receive percutaneous cardiopulmonary support (PCPS) for unstable hypoxemia and hypotension. Oxygenation improved, PCPS was withdrawn 2 days later, and the endotracheal tube was removed. Re-expansion pulmonary edema might cause fatal short-term cardio-respiratory failure. We considered that RPE requires appropriate early diagnosis, early treatment and aggressive therapy, including PCPS.

We report a rare case of 16-year-old boy who was given a diagnosis vasculo-Behçet disease after removing a right atrial thrombus. He was admitted to our hospital with abdominal pain and fever. He was underwent appendectomy for suspected appendicitis, but the appendix was normal. Additional image examinations revealed a mobile right atrial mass and inferior vena cava thrombosis, and the patient was sent to reoperation urgently to prevent pulmonary embolism. Surgery revealed the mass to be a thrombus. Vasculo-Behçet disease was diagnosed based on the patient's history and examination data. He was discharged on the 17th postoperative day. Cardiac mass excision should be immediately considered in such cases, and the differential diagnosis of Behçet disease was important for this case.

We report a rare case of type A acute aortic dissection with paraplegia which was cured immediately after an emergency operation. A 79-year-old woman was transferred to our institution with sudden back pain and paraplegia. Computed tomographic scans revealed a cardiac tamponade with an acute type A aortic dissection. She went into shock soon after arrival, and about 4 hours from onset we performed an emergency replacement of the ascending aorta. Three hours after the operation, her neurological deficit gradually resolved and could walk by postoperative day 3. This case suggests that early restoration of the blood flow to the spinal cord is mandatory to relieve paraplegia caused by type A aortic dissection.

Noncompaction of the left ventricular myocardium (NCLV) is a rare congenital cardiomyopathy resulting from an arrest in normal endomyocardial embryogenesis. The prognosis of NCLV is poor, including progress on to heart failure. However, some cases of NCLV in adults have been recently reported. To the best of our knowledge, there are only 3 cases of cardiac operations reported in patients with NCLV in adults. We describ a 54-year-old man with NCLV and severe coronary artery disease. Echocardiography demonstrated NCLV and low LVEF (25%). Coronary angiography (CAG) showed triple vessel disease with total occlusion of vessels #1 and #6. Tl-cintigraphy and magnetic resonance imaging (MRI) demonstrated viability from the base to the middle of the anterior wall. Coronary artery bypass grafting (CABG) was done after controll of the heart failure. The postoperative course was uneventful and the patient was discharged 7 days after operation. LVEF improved to 52% after surgery. Careful observation of cardiac function is vital because of the possibility of progression to heart failure.

A 38-year-old woman was admitted due to an abnormal ECG and dyspnea on effort. Transoesophageal echocardiography and cardiac computed tomography (CT) showed severe aortic regurgitation (AR) due to pentacuspid aortic valve, which consisted of 4 relatively equal cusps and 1 larger cusp. Mild mitral regurgitation, atrial septal defect (ASD) and coronary-pulmonary artery fistula were complicated for her. She underwent aortic valve replacement, mitral valve annuloplasty, direct closures of ASD and coronary-pulmonary artery fistula. The pathophysiology of the resected aortic valve showed 4 equal size cusps and a large one with mild myxomatous change. Aortic valve regurgitation due to pentacuspid aortic valve is extremely rare and there was little report concerning it in the literature. We reported the surgical repair of this rare case of severe AR due to pentacusupid aortic valve.

We report a case of type A dissecting aneurysm occurring after aortic valve replacement (AVR). The patient was a 67-year-old man with a history of AVR 4 years previously. Preoperative CT scan revealed a type A dissecting aneurysm 10cm in diameter, close to the sternum. Under preparation for selective cerebral perfusion (SCP), re-do median sternotomy was safely performed using partial extracorporeal circulation (ECC) via a femoral artery and vein. Because of severe adhesion in the upper part of the ascending aorta and aortic arch, a graft replacement of the ascending aorta was impossible. Under SCP via bilateral common carotid arteries exposed in the neck, the entry of the dissection, which was located in the previous aortotomy line, was closed with an ePTFE patch. SCP via bilateral common carotid arteries exposed in the neck appeared to be very useful and safe for such patients at risk for injury to the aorta during re-do median sternotomy and with severe adhesion, which made it difficult to establish SCP via the usual operative field. Although graft replacement is the standard operation for the treatment of the ascending aortic dissection, patch closure of the entry should be considered as a second-choice method in some case.

Aortic root replacement with a Freestyle^TM stentless porcine valve (Medtronic Inc.) was performed on a 32-year-old woman for aortic root aneurysm. The patient had been given a diagnosis of systemic lupus erythematosus and had been maintained on steroid therapy for 15 years. Lupus anticoagulant was present and the anticardiolipin antibody titer was abnormal as follows: IgG, 2.0IU/ml (normal<1.0IU/ml). For the patient requiring aortic root reconstruction, many options are available. The use of a biological valved conduit should be considered for patients in whom anticoagulation is not desirable. The Freestyle^TM stentless porcine valve offers an acceptable alternative to mechanical prostheses, especially for cases with contraindication for anticoagulant therapy, associated with antiphospholipid antibodies.

A 58-year-old man was admitted with a diagnosis of an acute Stanford type A aortic dissection after 20-year-long steroid therapy for hypopituitarism. The graft replacement of the ascending aorta was performed as an emergency procedure under deep hypothermic selective cerebral perfusion. We administered 1, 000mg of methylprednisolone during cardiopulmonary bypass, injected 500mg/day of hydrocortisone during postoperative day 1 to 4, and then administered orally 40mg/day of hydrocortisone. Then 200μg of levothyroxine sodium was given orally from postoperative day 6. There are some reports about acute aortic dissection associated with long-term steroid therapy in SLE or aortitis syndrome, but reports involving hypopituitarism are very rare.

A 85-year-old man was admitted to our hospital with a right iliac artery anastomotic pseudoaneurysm after aorto-biiliac Y-shaped graft replacement for the treatment of abdominal aortic and biiliac aneurysms. We performed an endovascular intervention of this anastomotic pseudoaneurysm with an ePTFE-covered stent-graft. This method seemed to be very useful even in such a high-risk patient, because it can be done under local anesthesia.
