Giant coronary aneurysm of Behcet's disease with sudden syncope: a case report

Behcet's disease is a chronic inflammatory syndrome that can affect arteries and veins of all sizes, rarely involving arteries, and is an unusual cause of myocardial infarction. We report a 28-year-old female patient who was admitted to our hospital with multiple sudden syncope. Cardiovascular risk factors such as hypertension (HT), diabetes and obesity were not found in her. Preoperatively, imaging examinations suggested thrombosis of inferior and superior vena cava and right heart combined with coronary artery aneurysm. The patient was finally diagnosed as a huge coronary artery aneurysm proximal to the left anterior descending artery. Syncope is considered to be caused by right ventricular outflow tract obstruction. The patient received successful aneurysm resection and had an uneventful postoperative recovery.
