Abstract

The coronary artery fistula (CAF) is an abnormal connection between the coronary artery and a major vessel or cardiac chamber. Coronary artery aneurysm (CAA) is defined as coronary dilatation that exceeds the diameter of normal adjacent segments or the diameter of the patient’s largest coronary vessel by 1.5~2.0 times. The intracranial space-occupying lesion is a group of diseases that occupy a particular space within the cranium, bearing many causes, such as trauma, tumors, infections, cerebrovascular disease, etc. The coexistence of these three diseases is rare and can lead to fatal complications, including heart failure, angina pectoris, acute myocardial infarction, and increased intracranial pressure. In this article, we report a case of a young patient who was diagnosed with multiple coronary artery fistula with a giant coronary aneurysm concomitant with right cerebellar occupancy and underwent complex surgical treatment at our institution. At follow-up, the patient recovered good myocardial perfusion. In this article, we discuss and analyze the disease characteristics of this patient and summarize the perioperative problems and decisions as a way to improve the prognosis and survival of CAF patients with multiple disease combinations.
