Thromboendarterectomy of Chronic Pulmonary Thromboembolism: A Case Report / 대한흉부외과학회지

ABSTRACT

Chronic pulmonary artery thromboembolism is a relatively rare phenomenon causing hypoxia and pulmonary hypertension that eventually leads to respiratory failure and right heart failure. Patients with acute pulmonary artery thromboembolism are generally treated with antithrombotics and thrombolytics. However, in cases with chronic pulmonary artery thromboembolism the fibrinized thrombus is so strongly adhered to the pulmonary artery wall that medical treatment becomes ineffective and surgical treatment must then be considered. We report a 47year old patient, with a history of repeated admission due to unresolved chronic obstructive pulmonary disease and chronic pulmonary artery thromboembolism at a local hospital, who underwent a successful endarterectomy of pulmonary artery thromboemboli using intermittent total circulatory arrest.
