Endovascular Embolization of Coronary Artery-Pulmonary Artery Fistulas with Double Coronary Aneurysms.

A 75-year-old woman with chest discomfort and a continuous murmur was admitted to our hospital. During noninvasive examination, computed tomography angiography showed a coronary artery-pulmonary artery fistula with double giant coronary aneurysms (one was 42 mm× 32 mm× 32 mm, and the other was 25 mm× 20 mm× 17 mm) arising from the proximal part of the left anterior descending (LAD) artery. Stress myocardial scintigraphy showed ischemia at the LAD area. Given her frailty, the heart team, including cardiac surgeons, judged that surgical treatment would be difficult. Thus, endovascular embolization for the abnormal vessels was selected. After coronary angiography, two coronary aneurysms were embolized by 53 coils, and the feeding artery was embolized by two coils and one Amplatzer Vascular Plug 4™. A small pulmonary artery fistula remained after the procedures; thus, additional embolization was performed 3 months after the index procedure. Thereafter, angiography showed no flow into the aneurysms, and her symptoms improved.Endovascular embolization might be an effective treatment to achieve aneurysm occlusion in patients at high risk for surgical treatment. Although the present case had double coronary aneurysms with a large feeder vessel, the combination procedure of coils and vascular plug was able to embolize this abnormal vessel.
