This study reports on a 57-year-old woman who underwent a 3rd mitral valve replacement and presented with complaints of fatigue. Laboratory examination revealed severe hemolytic anemia, and trans-esophageal echocardiography revealed a paravalvular leak (PVL) around the prosthetic valve at the posterior trigone in the mitral position. ⋯ The mitral PVL was successfully repaired with suture closure of the annular defect. The postoperative course was uneventful: postoperative echocardiography revealed no evidence of PVL, and the hemolytic anemia subsided.

We encountered a case of tracheal stenosis post tracheostomy, so-called cuff stenosis. A 43-year-old man with ventricular septal defect (VSD) was treated by oral endotracheal intubation because of heart-failure and pneumonia, and tracheostomy was performed. He was placed on artificial ventilation for almost 3 months. ⋯ Although the stenotic portion was dilated by an endotracheal tube, 47-days after dilation, the portion was restenosed to almost 7 mm in diameter. Therefore, surgical treatment was necessary and tracheoplasty was performed by end-to-end suture after 2 cm (4 ring) resection of trachea. Tracheoplasty is the most reliable method of treating cuff stenosis after tracheostomy.

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. ⋯ 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.

Case Reports
[Extensive traumatic pneumomediastinum. without injuries of organs in the thorax: report of a case].
A 57-year-old man was accidentally hit by concrete blocks weighing 3 tons on his right side, and was admitted to a hospital. The radiologic findings taken immediately after trauma demonstrated pneumo-mediastinum, subcutaneous emphysema with multiple rib fractures and right clavicle fracture. At computed tomography (CT) scan 16 hours after trauma, pneumomediastinum and subcutaneous emphysema turned out to be worsened with an increased bilateral pleural effusion. ⋯ The chest cavities and mediastinum were washed well with 3 liters of saline solution. The patient had a good course after surgery without any complications, and was discharged at the 18th hospital day. Mediastinal drainage by an emergency operation should always be a choice to a patient having a progressively worsening pneumomediastinum which might cause tachycardia, low blood pressure, and severe dyspnea due to compression of blood vessels and trachea.
