Catheter Embolization of Bronchial Arterial Collateral for Chronic Pulmonary Embolism with Massive Hemoptysis— A Case Report

A case of catheter embolization of the bronchial arterial collateral for chronic pulmonary embolism (PE) is reported. A patient suffering massive hemoptysis was diagnosed by bronchoscopy and bronchial arteriography as having PE with large bronchial arterial collaterals. Since the left iliac vein was thrombosed and multiple PE was revealed by angiography, it was thought that chronic PE, caused by iliac vein thrombosis, produced large bronchial arterial collaterals and caused bleeding. Catheter embolization of the right bronchial arterial collateral was suc cessfully employed, and hemoptysis ceased.
