Description
Background
A coronary-to-pulmonary artery fistula (CPAF) with a giant aneurysm is a rare clinical occurrence. The rupture of an aneurysm leads to a fatal outcome, thus prompting the incorporation of prophylactic measures, which have encompassed surgical resections or endovascular embolization procedures. The indications for these treatment strategies are controversial, and little has been elucidated regarding the salient characteristics underpinning the selection of a therapeutic strategy. We report a case of a giant aneurysm associated with CPAFs that was thrombosed before interventional treatment.
Case summary
A 43-year-old woman, who had previously undergone a right adrenalectomy for primary aldosteronism, was referred for an abnormal heart silhouette on a chest X-ray, which had not been seen three years earlier. Contrast-enhanced computed tomography and coronary angiography (CAG) revealed a giant aneurysm on the anterior aspect of the heart associated with two CPAFs. Because of the risk of rupture of the aneurysm, surgical resection was recommended; however, the patient requested endovascular therapy. On the day of intervention, CAG showed spontaneous occlusion of the feeding vessel to the aneurysm, and the aneurysm showed minimal contrast agent, suggesting spontaneous thrombosis. Because of possible recanalization of the aneurysm, coil embolization was performed, without complications. The patient remained asymptomatic, and the aneurysm was completely embolized at the one-year follow-up.
Discussion
The case shows that minimally invasive endovascular treatment is feasible instead of surgical resection for giant aneurysms associated with CPAFs, depending on their morphological characteristics. This perspective may offer novel insights into treatment strategies for CPAF.
