[Surgical treatment of coronary artery-pulmonary artery fistula with coronary aneurysm].
We experienced 4 cases of coronary artery-pulmonary artery fistula with coronary aneurysm, three patients had symptoms of chest pain, and 1 patient had cardiac murmur. Coronary arteriography showed that three patients had fistulas from the left coronary artery to the pulmonary artery; and that 1 patient had a fistula from both the right and left coronary arteries to the pulmonary artery. Moreover, 1 patient had 90% diameter stenosis of segment 7. The maximum diameter of the coronary aneurysm ranged from 12 to 20 mm (average: 15.3 mm). One patient underwent closure of the opening of the fistula, 2 patients underwent multiple ligatures of fistulas, and 1 patient underwent multiple ligatures of fistulas with coronary artery bypass grafting. The postoperative course of every patient was uneventful. There have been 42 reports on this abnormality in Japan. We should treat the fistula as early as possible to prevent cardiac complications such as myocardial ischemia and rupture of coronary aneurysm.
