An operative case of aneurysm of peripheral pulmonary artery / 日本心臓血管外科学会雑誌

Aneurysm of peripheral pulmonary artery was rarely reported. A 51-year-old man who was pointed out a coin lesion at the right hilus region on the chest X-ray film complained back chest pain. Selective pulmonary arteriography revealed the peripheral pulmonary aneurysm of saccular dilatation running into the middle lobe. Aneurysmectomy was performed successfully and the patient returned to social work. Pathologic specimen revealed partly necrosis of medial cell. Eleven surgical cases including this case were reported in Japan. A brief review of the literature was made.
