The pulmonary sequestration is rare congenital pulmonary disease with nonfunctioning lung tissue supplied by aberrant arteries arising from systemic arteries-thoracic aorta, subclavian artery, innominated artery, internal mammary artery, etc. In our country, only 23 cases were reported previously and the majority was intralobar pulmonary sequestration except 2 cases.
The patient was 17 year-old man and admitted due to intermittent cough, productive sputum and fever for 8 years. On simple chest PA view´, multiple cysts with air-fluid levels were located at left lower lobe area. Aortogram revealed two aberrant arteries arising from thoracic aorta just above, the diaphragm.
On the operative field, the arteries were 0.7 and 0.3 cm in diameter. Left lower lobectomy was done with ligation of aberrent arteries. The patient was recovered and discharged uneventfully.
