[A case of successful operation of acute pulmonary embolism due to right ventricular thrombus detected by two-dimensional echocardiography].

: A 44-year-old woman suddenly developed dyspnea and loss of consciousness four days after cholecystectomy. Under the diagnosis of acute pulmonary embolism, the patient was treated with anticoagulant with temporary relief of her symptoms. But emergency embolectomy was performed because of large right ventricular thrombus detected by two-dimensional echocardiography. Many reports suggest a relationship between pulmonary embolism and right-sided cardiac thrombi. We consider that two-dimensional echocardiography is essential in case of acute pulmonary embolism.
