Pulmonary embolism is a common but vexing illness. This book provides a contemporary overview of the most important issues from a Western and a Japanese perspective, providing the reader with state-of-the-art knowledge of the epidemiology and molecular biology of the disease. In the Diagnosis section, the relationship between venous thrombosis and pulmonary embolism is explored, and exciting new findings are presented in the fields of echocardiography and magnetic resonance imaging. The Management section focuses on surgical intervention with acute embolectomy as well as updating thromboendarterectomy for chronic pulmonary embolism. The importance of primary and secondary prevention is emphasized in chapters addressing low molecular weight heparin and the inferior vena cava filter. This cutting-edge book is a valuable resource for practicing physicians, researchers, and students in internal medicine, hematology, pulmonary critical care, and vascular medicine.
