An 88-year-old woman presented at a local hospital with a left femoral pulsatile mass. CT revealed saccular aneurysms with irregular intima in the descending thoracic aorta, the right common femoral artery and the left superficial femoral artery. They were 60 mm, 30 mm, and 25 mm in diameter, respectively. After referral to our hospital, multiple inflammatory aneurysms were strongly suspected by detailed examinations. Endovascular treatment including thoracic endovascular aortic repair and surgical replacement were performed by two-stage operations. After steroid therapy was started postoperatively, her c-reactive protein (CRP) value decreased. Nevertheless, the thoracic aortic aneurysm enlarged and she died due to hemorrhage. Multiple inflammatory aneurysms are extremely rare. We consider that appropriate steroid therapy and close follow-up are most important.

An 80-year-old man presented with a history of retrosternal gastric tube reconstruction for esophageal cancer. He experienced sudden chest pain, and temporarily lost consciousness, before being transferred to our hospital. Contrast-enhanced computed tomography revealed acute Stanford type A aortic dissection and a retrosternal gastric tube. We performed emergency operation using a median sternotomy approach. Before median sternotomy, we detected the gastric tube in the subxiphoid and suprasternal spaces. The anterior and right sides of the gastric tube were dissected bluntly from the posterior surface of the sternum and median sternotomy was performed. The gastric tube was mobilized to the left side and we were able to obtain the usual operative view for ascending aorta graft replacement. Intraoperatively, the gastric tube remained intact and uninjured. The patient was transferred to another hospital for rehabilitation on postoperative day 34.

We describe the case of a 60-year-old woman with severe aortic stenosis and severe calcification of the thoracic aorta, who underwent an apico-aortic conduit bypass using an aortic valved graft. Because of stenosis of the annulus of the aortic valve and severe calcification of the thoracic aorta (porcelain aorta), we did not perform ordinary aortic valve replacement. Instead, apico-aortic conduit bypass surgery was performed using a St. Jude Medical Aortic Valved Graft (19-20 mm : St. Jude Medical, St. Paul, MN, USA) and cardiopulmonary bypass (CPB) surgery was performed using descending aortic perfusion and left pulmonary artery drainage, while the subject was in the right decubitus position. The descending aorta was clamped and a 20-mm graft (Hemashield Platinum ; Boston Scientific/Medi-tech, Natick, MA, USA) was sutured to it. Under ventricular fibrillation, the left ventricular apex was circularly resected using a puncher with a diameter identical to that of the 20-mm graft, in order to create a new outflow for the conduit bypass. The graft was sutured to the outflow, and a torus-shaped equine pericardial sheet was used to reinforce the suture line. After recovery of the heartbeat, the aortic valved graft was first sutured to the graft at the outflow and then to the graft at the descending aorta. The CPB time was 285 min and ventricular fibrillation time was 36 min. Therefore, the benefits of using an aortic valved conduit for apico-aortic conduit bypass are reduced operation time, since there is no need to prepare a handmade valve conduit, and easy management of the grafts which are made of the same material.

A 66-year-old man with an unknown medical history developed chest pain and a diagnosis of acute myocardial infarction (AMI) was given by his physician. Percutaneous coronary intervention was performed in the left anterior descending artery. Echocardiography revealed ventricular septal perforation (VSP) ; therefore, the patient was transferred to our hospital. After admission, his platelet count dropped rapidly during heparin administration, and left ventricular thrombosis and deep vein thrombosis were noted, raising a suspicion of heparin-induced thrombocytopenia (HIT). To establish cardiopulmonary bypass, argatroban alone was insufficient to prolong the Powered by Editorial Manager^® and ProduXion Manager^® from the Aries Systems Corporation activated clotting time (ACT) ; thus, nafamostat mesilate was also used for coronary artery bypass grafting and surgical repair of VSP. It took many hours to normalize the ACT, requiring re-exploration for excessive bleeding. On the 37th postoperative day, the patient was transferred to another hospital. We performed cardiac surgical procedures using argatroban in a patient who developed HIT during the course of VSP following AMI ; however, we had difficulty in controlling the ACT. Since, to the best of our knowledge, there are no previous studies reporting surgical case of VSP complicated by HIT, we present this case with a review of the relevant literature.

The case was a 27-year-old woman with a history of Turner syndrome. The patient underwent ascending-descending aorta bypass for aortic coarctation 6 years previously and underwent subsequent follow-up on an outpatient basis. She consulted our department because of fever, chest pain and headache as the main complaints. Age-indeterminate type A aortic dissection was found on computed tomography, and she was admitted to the hospital on the same day. Echocardiography also revealed an enlarged aortic root and bicuspid aortic valve. Aortic root replacement and total arch replacement were performed, and her postoperative course was favorable. It is reported that in cases of Turner syndrome with aortic coarctation, aortic aneurysm and aortic dissection are likely to occur due to the vulnerability of the aortic wall. We encountered a patient with Turner syndrome who underwent ascending-descending aorta bypass for adult aortic coarctation and subsequently developed type A aortic dissection, underwent aortic root and total arch replacement, and rehabilitated after surgery, as well as provide bibliographic considerations.
