[A case of chronic pulmonary emphysema with a past history of bilateral carotid body resection].
A 76-year-old man, whose carotid bodies had been resected for treatment of bronchial asthma 40 years previously was admitted for evaluation of abnormal arterial blood gases and exertional dyspnea. The case was diagnosed clinically as chronic pulmonary emphysema. His peripheral chemoreceptor function, estimated by hypoxic ventilatory and P0.1 response tests and withdrawal test was non-functioning. His PaCO2 value tended to rise over 50 Torr either after light exercise or during airway infection, though it was normal at rest. In addition his dyspnea had continued for 40 years in spite of carotid body resection. It was concluded that the effect of carotid body resection lasts more than 40 years and it does not have a good effect on COPD.
