[A case of coronary-pulmonary artery fistula with saccular aneurysm].

Recently, due to the wide-spread use of coronary angiography (CAG), reports of coronary-pulmonary artery fistula have become more frequent. However, a case of coronary-pulmonary artery fistula with saccular aneurysm is very rare. We report a case of coronary-pulmonary artery fistula with saccular aneurysm which was discovered as an abnormal chest shadow. A sixty-two-year old female was admitted to our hospital with an abnormal chest shadow. CAG showed fistula from the left anterior descending coronary artery (LAD) proximal to the pulmonary artery (PA), and also from the LAD distal to the PA, with saccular aneurysm. Due to the risk of a rupture of the saccular aneurysm, we performed a resection. After this operation, no abnormal chest shadows appeared on the chest X-rays. CAG showed no saccular aneurysm and she is progressing favorably.
