Vocal Fold Paralysis Secondary to Subclavian Venous Thrombosis

The etiology of vocal fold paralysis is multifaceted. One of the rare causes is internal jugular vein thrombosis secondary to central venous catheterization. The palsy is usually ipsilateral to the site of indwelled catheterization, self-limited and reversible. The authors of this manuscript report a rare case of contralateral recurrent laryngeal nerve palsy induced by subclavian vein thrombosis following central venous catheterization. The patient developed irreversible vocal fold paralysis that necessitated office-based injection laryngoplasty.
