Methods The clinical data of 12 cases with chronic pulmonary thromboembolism, who underwent thromboendarterec- tomy assisted by low flow or circulation arrest with deep hypothermia, were reviewed retrospectively. Results Pulmonary artery pressure decreased 20 to 40 mmHg immediately after surgical procedures in 9 cases. The postoperative pulmonary edema at various degrees happened in 12 cases, among them, 1 died of severe lung infection and pulmonary re-embolism at 19 days postoperation. Computed tomography pulmonary angiography and angiography of 11 cases indicated that the original obstruction of pulmonary artery disappeared. During the follow-up period of 2 months to 5 years, the clinical symptoms and activity was improved. Conclusion Thromboendarterectomy is an effective treatment for chronic pulmonary thromboembolism. The outcome of the surgical procedure needs to be further investigated and followed up regularly according to an evaluative system, because it might be influenced by multiple factors.展开更多

Until recently, the diagnosis is often not established until the tumor is advanced with vital cardiac structure involved or distal metastasis, mainly because the symptoms are initially nonspecific. The natural history of cardiac angiosarcoma is characterized by a short clinical course and a fatal outcome. Surgical resection remains the preferential therapy for palliation or cure, where as irradiation and chemotherapy have only limited use. We herein reported a successful radical resection of cardiac angiosarcoma with concomitant reconstruction of right coronary artery, tricuspid leaflet, and atrial wall.
