BackgroundRefractory seizure activity represents a difficult problem for both patients and practitioners. Implantation of the vagal nerve stimulator has been posited as an effective treatment for refractory seizure activity. These devices are inserted by placing leads into the carotid sheath along the vagus nerve. We evaluated a vascular surgeon's experience placing vagal nerve stimulators.MethodsWe examined all patients treated with placement of vagal nerve stimulator by a single surgeon from October 2016 to October 2018. Data collected included demographics, medical and surgical history, intraoperative variables, and complications.ResultsThirty-four patients underwent placement of a vagal nerve stimulator. About 29.4% had a previous vagal nerve stimulator placed on the ipsilateral side. Intraoperative bradycardia was seen in 1 patient. Postoperative complications were identified in 5 patients, all of which were transient dysphagia or changes in voice quality which did not require intervention. There was no significant difference between patients with the previous operation and those without for developing postoperative complications (P = .138). Average blood loss was higher in patients who had undergone previous stimulator placement than those who had not (P = .0223), and the operative time was longer (P ≤ .0001).DiscussionGiven the anatomical location of placement, vascular surgeons may be called upon to place these devices. In our single surgeon series, we found that the placement was safe, with minimal complications. Intraoperatively, this case appears to be more difficult (with higher blood loss and longer operative time) in patients who have had previous device placement, but this does not appear to lead to increased complications.
