Case ReportsAcute aortic syndrome: a 'last glance' before incision.
Acute aortic syndrome (AAS) (aortic dissection, intramural aortic haematoma, or penetrating atherosclerotic ulcer) is a surgical emergency. Computed tomography (CT) is the reference technique for the diagnosis of this critical situation. ⋯ We describe the case of a 76-year-old man with clinical signs of AAS and a CT-scan compatible with a diagnosis of aortic intra-mural haematoma, leading to emergency surgery. The peroperative findings revealed a normal aortic wall with the presence of an unusual pericardial recess at the right side of the aorta.

Comparative StudyElectrothermal bipolar vessel sealing device LigaSureV for pulmonary artery ligation--burst pressure and clinical experiences in complete video-assisted thoracoscopic major lung resection for lung cancer.
Intraoperative bleeding is one of the main severe complications in complete video-assisted thoracoscopic surgery (c-VATS). We investigated whether one sealing device, the LigaSureV (LSV) vessel sealing system (Valleylab, Tyco Healthcare, Boulder, CO, USA) was experimentally and clinically safe and effective for c-VATS. The burst pressures (BP) of each pulmonary artery (PA) in resected lungs were measured and were compared between a thin PA group (<5 mm) and a thick PA group (> or =5 mm). ⋯ However, average BP was physiologically high enough to inhibit a burst even for thick PA sealed in a wet state. There was single case of delayed bleeding sealed PA resulted from seal contact with a sucton device. These studies demonstrated the safety and efficacy of the LSV to sealed PA in c-VATS.

Case ReportsPrimary pleomorphic liposarcoma of pericardium.
We report a case of a 42-year-old man, who presented with a three-weeks' history of dyspnea and chest oppression induced by light activity, who had a large mass in the pericardium. Computed tomography showed a non-homogeneous density lobulated mass in the pericardial sac. ⋯ The patient is still alive 18 months after the diagnosis was made. The rare incidence of the liposarcoma of the pericardium can easily lead to a misdiagnosis clinically, and the final diagnosis here was made histopathologically.
