Giant aneurysm of main pulmonary artery

Aneurysm of the main pulmonary artery is an extremely rare entity. The first successful repair of an aneurysm of the main pulmonary artery was reported in 1971. Since then, surgical correction of the aneurysm of main pulmonary artery has been undertaken in only 6 cases. A thorough survey of the literature, including autopsy cases, medical cases, and surgical cases, shows the aneurysm in the present case to be one of the largest.
