Malignant pleural mesothelioma is an aggressive neoplasm with poor prognosis. Extrapleural pneumonectomy is performed as surgical therapy. It is difficult to obtain enough range of view at costophrenic angle. ⋯ With this procedure, a wide view of costophrenic angle and costal-pericardial angle can be obtained, and the resection margin can be placed outside the chest wall, costophrenic angle and costal-pericardial angle, which enables complete resection of masses at the costophrenic and costal-pericardial angles. Furthermore, extrapleural pneumonectomy with wide resection of the chest wall minimizes the resulting dead space, thereby minimizing the risk of postoperative hemorrhage and empyema. We consider that this procedure can be applied for malignant mesothelioma patients, especially those who have pleural masses at costophrenic angle.

Comparative Study
[Effects of dexmedetomidine hydrochloride on postoperative sedation in cardiovascular surgery].
Postoperative assessment of brain damage in cardiovascular surgery is often obscured by sedatives. Therefore, early postoperative detection of brain attack and its treatment are also hampered. A newly approved sedative, dexmedetomidine hydrochloride has weak analgesic effect and no respiratory depressive effect. These characteristics allow early assessment of brain damage after surgery. In this report, we compared 2 sedatives, propofol and dexmedetomidine hydrochloride, in cardiovascular settings. ⋯ Dexmedetomidine hydrochloride has no major hemodynamic nor other side effects after cardiovascular surgery. Dexmedetomidine hydrochloride could be used as an effective agent for postoperative sedation and analgesia in cardiovascular settings.

We herein present 2 cases of metastatic lung tumor derived from uterine leiomyosarcoma. In the case 1, a 59-year-old woman was admitted to our hospital to examine abnormal shadow detected on chest X-ray. She had undergone hysterectomy and oophorectomy for uterine leiomyosarcoma 19 months previously. ⋯ Exploratory laparotomy revealed the tumor was unresectable, and she received 4 courses of chemotherapy (paclitaxel and carboplatin). For metastatic lung tumor from uterine leiomyosarcoma, surgery has been considered the best choice. However, for patients with uterine leiomyosarcoma who cannot be treated surgically because of multiple metastatic tumors or poor surgical risk chemotherapy (paclitaxel and carboplatin) or stereotactic radiotherapy can be strategies.

An interrupted aortic arch was diagnosed in a 10-day-old girl weighing 3.3 kg, as was perimembranous ventricular septal defect (VSD) and severe tricuspid valve regurgitation (TR). The subaortic diameter was 3.6 mm and the aortic valve (3.7 mm in diameter) was bicuspid. We chose definitive repair, modified Yasui procedure, because of severe TR and no straddling of mitral valve. ⋯ Left ventricular outflow tract reconstruction consisted of intracardiac rerouting from the VSD to the pulmonary artery by using expanded-polytetrafluoroethylene (ePTFE) and Damus-Kaye-Stansel (DKS) anastomosis. Right ventricular outflow tract reconstruction was performed by the Rastelli procedure with an ePTFE valved conduit. Moreover, we carried out semicircular annuloplasty for severe TR.

Case Reports
[Traumatic diaphragmatic hernia presenting with shock 1 year after blunt injury; report of a case].
A 62-year-old male who had had the left femoral neck fracture due to a traffic accident 1 year earlier was admitted to our hospital because of abdominal pain. He was diagnosed with a left traumatic diaphragmatic hernia due to the previous traffic accident; his condition was also complicated by shock because the mediastinum was compressed by his severely dilated stomach. ⋯ A thoracotomy revealed a large defect, about 5 cm in size, at the central tendon of the left diaphragm and a severely dilated stomach in the left thoracic cavity. The ruptured diaphragm was closed directly after reduction of the stomach.
