Recurrent laryngeal nerve palsy complicating subclavian line insertion: A case report

Introduction. Although recurrent laryngeal nerve injury has been described following central venous access via the jugular route, it has not previously been reported following access via the subclavian route. Case presentation. A 63-year-old man presented with acute dysphonia immediately after insertion of a Hickman line via the subclavian route. Flexible laryngoscopy revealed a left vocal fold palsy. A computed tomography scan from the skull base to the thoracic inlet showed no obvious abnormality other than an abducted left vocal cord. The timing of the events and the computed tomography scan results strongly support the conclusion that the left recurrent laryngeal nerve was injured during insertion of the Hickman line, resulting in a left adductor vocal cord palsy. Conclusion. This case illustrates an unusual example of iatrogenic injury to the recurrent laryngeal nerve. It is important to recognize the possibility that such injuries may occur in order to prevent them. © 2009 Fishman; licensee Cases Network Ltd.
