Vocal cord paralysis is one of the frequently encountered complications after aortic surgery. However, reports of vocal cord paralysis after aortic surgery have been limited. In a retrospective cohort study of vocal cord paralysis after aortic surgery at a general hospital, we sought factors related to its development after aortic surgery to the descending thoracic aorta via left posterolateral thoracotomy. We reviewed data for a total of 69 patients who, between 1989 and 1995, underwent aortic surgery to the descending thoracic aorta. We assessed factors associated with the development of vocal cord paralysis and postoperative complications. Postoperative vocal cord paralysis appeared in 19 patients. Multiple logistic regression analysis revealed two risk factors for vocal cord paralysis: chronic dilatation of the aorta at the left subclavian artery (odds ratio = 8.67) and anastomosis proximal to the left subclavian artery (odds ratio = 17.7). The duration of mechanical ventilation was significantly prolonged for patients with vocal cord paralysis. Certain surgical factors associated with left subclavian artery increase the risk of vocal cord paralysis after surgery on the descending thoracic aorta. Vocal cord paralysis after aortic surgery did not increase aspiration pneumonia but was associated with pulmonary complications.
