Some investigators have identified that the rate of sternotomy was higher among patients with RSG whose goiter was below the lower limit of the aortic arch or extended toward the posterior mediastinum, or in the presence of ectopic mediastinal goiter, recurrent goiter or malignancy adhered to mediastinal structures (13-15,19).

American Heart Association (AHA) guidelines regarding prevention of stroke in patients with stroke and transient ischemic attack recommend that patients with adherent or mobile aortic arch thrombus should be treated medically to minimize cerebral embolic events rather than undergone an aortic arch endarterectomy or a cardiac procedure due to increased rate of intraoperative stroke [18].
