[Pulmonary and endobronchial tuberculosis with subclavian artery-pulmonary artery shunts].

A 77-year-old woman with a productive cough and fever was admitted to the hospital. Pulmonary and endobronchial tuberculosis, pneumonia of the left upper lobe, and stenosis of the left main bronchus were diagnosed. She was given the antimycobacterial drugs isoniazid, rifampin, and streptomycin, and her condition improved. Two months later, bronchoscopy revealed semilunar-shaped stenosis of the left main bronchus, and auscultation revealed wheezing in the middle-end expiratory phase. A continuous flow murmur (Levine III) was also heard at the left anterior chest wall. Cardiac catheterization with subclavian arteriography revealed two left subclavian-pulmonary shunts. In a case of systemic-pulmonary shunt such as this, the bronchial stenosis could be surgically repaired, but the result would be an increase in dead space. If left untreated, the pulmonary hypertension would progress and symptoms of pulmonary disease would become more severe. Subclavian-pulmonary artery shunt is a very rare complication of pulmonary tuberculosis. Surgical treatment should consist of open bronchoplasty along with lobectomy and removal of the shunt, rather than embolization of the shunt and endoscopic bronchoplasty.
