A 78-year-old woman, suffering from acute massive pulmonary embolism, was successfully treated with transvenous pulmonary embolectomy by catheter. This patient had been suffering from oppressive chest sensations during exercise, and diagnosed and treated as angina pectoris at a nearby clinic. She consulted our hospital complaining that her chest pains were increasing in frequency. She was admitted to our hospital on July 7, 1988, for coronary angiography (CAG), which she underwent on July 8 by the right femoral approach. After the CAG, she was ordered to rest in bed overnight, with the right inguinal region compressed. 18 hours later, the compression was removed and she was allowed to walk. Soon after she walked to the toilet, she complained of chest discomfort and fell into shock (systolic blood pressure was 60 mmHg). An ECG examination showed a right bundle branch block and an inverted T wave in lead V1-3. An echocardiography showed normal contraction of the left ventricle, but an enlargement of the right ventricle and a flattened interventricular septum. An analysis of arterial blood gas showed hypoxia (Pao2 52.5 mmHg, Paco2, 30.9 mmHg). Acute pulmonary embolism was suspected. 240,000 units of urokinase were administered intravenously, and pulmonary angiography was performed immediately. It revealed that the bilateral pulmonary arteries were almost completely obstructed. Although 720,000 units of urokinase were infused into the pulmonary artery, the obstruction did not improve. At that time, we performed a transvenous pulmonary embolectomy. We used a Judkins R 4 guiding catheter for PTCA made by USCI. The catheter was inserted into the pulmonary artery and clots were aspirated with a syringe.(ABSTRACT TRUNCATED AT 250 WORDS)

To contribute for making early diagnosis and treatment of acute pulmonary embolism (APE), we investigated on clinical pictures of 225 patients with APE. Common underlying factors were heart disease, prolonged bed rest, post-surgical state, thrombophlebitis, malignant tumor and post-catheterization state in this order. Dyspnea, chest pain, tachycardia and shock were frequently seen as initial symptoms and signs. Blood screening showed leukocytosis, hypoxemia, hypocapnia and elevated serum LDH. Electrocardiographic findings highly demonstrated were ST.T abnormalities, such as T inversion with ST elevation in V1-3, ST depression in V4-6 and sinus tachycardia. Chest X-rays showed diminished pulmonary vascular marking and pulmonary artery dilation. Right ventricular dilatation were frequently seen on 2-dimensional echocardiograms. Pulmonary artery pressure were elevated up to 49/20 (30) mmHg. Twenty-five percent of the patients died, and the recurrence was seen in 4%. Thus, as soon as APE is suspected by above clinical findings, definitive diagnosis should be obtained by the lung perfusion scan and pulmonary arteriography, then oxygen and thrombolytic agents should be given immediately to prevent the fatal outcome.

A 55-year-old man presented with the emergency department after having a short syncopal episode and angina during the exertion for 1 month. His initial electrocardiogram showed minimal ST-segment changes on precordial leads. While waiting for the laboratory tests, abruptly, the patient went into cardiopulmonary arrest. After a short resuscitation, a new electrocardiogram revealed ST-segment elevations in leads V1-3 and AVR, mimicking an anteroseptal myocardial infarction. Although, the angiography showed severe coronary artery disease, coronary flow was normal and main branches of pulmonary artery were almost fully occluded by large pulmonary emboli. Recombinant tissue plasminogen activator bolus (25 mg) was given 2 times at 5-minute intervals immediately into pulmonary artery by pig-tail catheter under the cardiopulmonary resuscitation. The patient had an excellent response to high-dose bolus thrombolytic therapy. We conclude that in the case of massive pulmonary embolism with small chance of resuscitation, the catheter-directed high-dose bolus injection of recombinant tissue plasminogen activator could enrich the therapeutical possibilities.
