OBJECTIVE This study was designed to clarify the optimal treatment mode of patients with intramural hematoma (IMH) of the thoracic aorta. METHODS From 1992 through 1997, 51 patients underwent surgical repair or medical treatment of IMH of the thoracic aorta. There were 36 male and 15 female patients, aged between 49 and 79 years with a mean of 67 years.(More)
A 42-year-old woman with choriocarcinoma required emergency pulmonary embolectomy under cardiopulmonary bypass. After diagnosis of choriocarcinoma was confirmed by examination of tumor emboli specimens, the patient was treated and had complete remission by chemotherapy over a 6-month period. Although rare, choriocarcinoma should be considered in the(More)
Patients who had undergone prosthetic valve replacement were treated with warfarin (anticoagulant) alone or in combination of ticlopidine (200 mg/day) or aspirin (81 mg/day) (anti-platelet agents). The study of blood coagulation factors and platelet aggregation were carried out with these cases. 1) The patients (n = 24) receiving warfarin for 21 days after(More)
We report herein the case of a 33-year-old man who survived an impalement injury of the thorax involving the heart, esophagus, and spinal cord. The patient was transported to our hospital with the impalement object left in situ and it was extracted under cardiopulmonary bypass in an operating room. The important principles of surgical management(More)
An experience with temporary filter placement, which seems to be safe and effective for temporarily preventing pulmonary embolism, is reported. Since October 1997, six patients had temporary filters. There were two men and four women, with a mean age of 37 years. Three filters were placed at the infrarenal inferior vena cava, two at the suprarenal inferior(More)
Although atypical pulmonary carcinoids frequently metastasize to regional lymph nodes, they rarely metastasize to the brain. We describe herein an extremely unusual case of a 52-year-old woman who presented with the symptoms of brain metastasis as the initial manifestation of an atypical pulmonary carcinoid. After control of the multiple metastatic brain(More)
Placement of permanent filters in the superior vena cava (SVC) for preventing pulmonary embolism (PE) arising from thrombi superior to the right atrium has rarely been performed. The authors report the first case of temporary filter insertion in the SVC because of upper extremity thrombosis accompanied with PE. After thrombectomy, the temporary filter was(More)
The authors report a successful application of hypothermia, along with intra-aortic balloon pump (IABP) support, to postcardiotomy ventricular failure. Surface-cooling hypothermia was applied in 8 patients after open heart surgery. The original cardiac procedure consisted of 3 aortocoronary bypass graftings (ACBGs), 2 aortic valve replacements (AVRs), 1(More)
A 36-year-old woman was admitted because of an enlarged right heart. Echocardiographic examination revealed an abnormal vessel connecting to the dilated coronary sinus. The abnormal vessel traveled in the direction from the right axillary to the left epigastric region. Partial anomalous pulmonary venous connection (PAPVC) from the right upper lobe to the(More)
