Arteria Lusoria or aberrant right subclavian artery (ARSA) is present in 0.6-1.4% of individuals. It typically remains clinically silent and is often discovered during angiographic procedures. The presence of ARSA can make a right transradial approach for coronary angiography and angioplasty technically more difficult. With the use of catheter support, we describe two cases in which a right tra...

Contrast enhanced computed tomography of the mediastinum in our patient revealed this anomalous vessel arising from the aortic arch distal to the left subclavian artery which passed behind the esophagus as it traveled to th...

BACKGROUND A nonrecurrent laryngeal nerve (NRLN) is a rare but potentially serious anatomical variant. Although the incidence is reported to be 0.3% to 1.3%, it carries a much higher risk of palsy during thyroid surgery. The objective of this study is to investigate the usefulness of computed tomography (CT) for preoperative identification and intraoperative neuromonitoring identification (IONM...
