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

Behcet's disease(BD) is a chronic inflammatory vasculitis that rarely affects the arteries, making myocardial infarction unlikely. We report a 28-year-old 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 the inferior and superior vena cava and right heart combined with coronary artery aneurysm. The patient was finally diagnosed with a huge coronary artery aneurysm proximal to the left anterior descending artery. Syncope is considered to be caused right ventricular outflow tract obstruction. The patient received a successful aneurysm resection and had an uneventful postoperative recovery.
