Non‐recurrent laryngeal nerve and arteria lusoria: Rare and little known association

Abstract

Abstract Non‐recurrent Laryngeal nerve is constantly associated with Arteria Lusoria. Knowing this association is the basis of predicting this condition preoperatively. Ultrasonography assessment before thyroid and parathyroid surgery should include identification of brachiocephalic trunk division. Absence of its visualization indicates Arteria Lusoria and then non‐recurrent laryngeal nerve.
