[A case of acute massive pulmonary embolism successfully treated with transvenous pulmonary embolectomy by catheter].
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)
