A Case of Aberrant Right Subclavian Artery (Arteria Lusoria) with Chest Tightness and Coughing

  • 1Department of Internal Medicine, Dong-A University College of Medicine, Busan, Korea.


The left aortic arch with an aberrant right subclavian artery, or arteria lusoria, is the most common aortic arch anomaly, occurring in 0.5-2.5% of individuals. In such cases, the angular course of the arteria lusoria to the ascending aorta imposes difficulty in passing a guide wire to the ascending aorta during right transradial catheterization. Here, the case of a 53-year-old woman with intermittent chest tightness and coughing is reported. Aberrant right subclavian artery (arteria lusoria) was diagnosed via aortogram during right transradial coronary angiography. Compression of the esophagus and trachea by the aberrant right subclavian artery was demonstrated by chest computed tomography (CT).
