[Aneurysm of the pulmonary artery. Analysis of 7 cases].

Aneurysms of the pulmonary artery are very rare, very few have been reported in medical literature. It is the purpose of this paper to present and discuss 7 cases. The etiology was congenital in 2, syphilitic in 2, cystic medionecrosis in 1, and mycotic in 2. The diagnosis was confirmed by necropsis in 3, and by angiography in 4. The basic clinical aspects are hemoptysis, pulmonary ejective murmur, and the radiological findings. The evolution depends on the etiology. The mycotic aneurysms ruptured and the patient with cystic medionecrosis died in heart failure. One of the syphilitic aneurysms died from an unrelated cause, and the others are alive and asymptomatic. The medical treatment is determined by the etiology.
