A rare case of Vieussens’ arterial ring with multiple pulmonary fistulas and aneurysms

摘要

An abnormal connection between the conus branches of the right and proximal left anterior descending (LAD) coronary arteries is referred to as Vieussens’ arterial ring (VAR). There are many pieces of VAR-related literature, including case reports and comments. However, the occurrence of VAR combined with pathological changes is extremely rare. Usually, VAR is not detected easily and patients do not present with any clinical symptoms. When a patient experiences symptoms such as chest tightness and chest pain, relevant imaging examinations may indicate this disease’s existence. Here, we report a case of VAR with multiple pulmonary fistulas and aneurysms. After comparing various medical imaging examination methods, we believe that coronary computed tomography angiography (CCTA) is the most beneficial imaging method for displaying this complex disease.
