Delayed cardiac tamponade is an unusual but serious complication of cardiac surgery. Echocardiography and computed tomography (CT) are well established methods for the detection of pericardial effusions. Catheter insertion guided by CT has been used to accomplish non operative drainage of symptomatic postoperative pericardial effusion in seven cases. ⋯ General pericardial effusion around the heart is classified as type 1, effusion adjacent to the right side of the heart as type 2 and left side as type 3, effusion localized only at the apex as type 4. CT imaging is useful not only to localize and assess the size of the effusions, but also to select the way of catheter insertion. As the fluid might be trapped in compartments, for instance right-sided or left sided type, investigation of the pericardial spaces is important in planning a catheter pericardiocentesis.

Case Reports
[Ruptured dissecting aneurysm of the transverse arch after replacement of the descending and ascending aorta].
A 28-year-old Marfan's syndrome woman was referred to our hospital because of sudden chest and back pain. She had received replacement of the descending and ascending aorta for acute aortic dissection previously in other two institutions. ⋯ She recovered uneventfully although she had residual thoracoabdominal dissecting aneurysm. It was suggested that total arch replacement should be performed for Stanford A type dissection in Marfan's syndrome.

A 41-year-old man, who had undergone descending aortic repair following rupture of the DeBakey type III aortic dissection, underwent thoracoabdominal aneurysm repair 1 year after the first surgery. The operation was performed by partial-clamping and single crossclamping without using assisted bypass or shunt, in order to minimize bleeding ensuing the re-thoracotomy and dissection between lung and the graft.

Laryngeal mask which is widely used in clinical anesthesiology permits establishment of airway without tracheal intubation. Flexible bronchoscopy or bronchoscopic treatment using the laryngeal mask was evaluated to determine its safety, less invasiveness, and usefulness. Fifty-two patients underwent flexible bronchoscopy or bronchoscopic treatment using laryngeal mask 54 times. ⋯ There were three patients with sore throat and one with an unpleasant feeling in the pharynx following the examination, however, all of these complaints resolved within three days after the examination. Laryngeal masks are less invasive and have very little effect on either the respiratory system or the circulatory system. They may be used safely even in aged patients and appears to be highly effective for diagnostic and therapeutic bronchoscopy.

A 21-year-old man; complaining of left chest pain and dyspnea, was admitted to our hospital with a diagnosis of spontaneous pneumothorax. Though chest X-ray on admission did not show hemothorax, chest drainage revealed intrapleural bleeding. As chest X-ray on the following day showed evident fluid level, emergency operation was carried out with a diagnosis of spontaneous hemopneumothorax. ⋯ The bulla was resected following hemostasis. After improvement of complicating postoperative re-expansive pulmonary edema, the patient was discharged on the 18th postoperative day. On treatment of spontaneous hemopneumothorax, existence of such a case as ours should be taken into account.
