Carotid angioplasty and stenting is a newer treatment for carotid stenosis. It is a catheter-based procedure and requires the use of a cerebral protection device to prevent embolization. Dye is used for visualization as CO2 cannot be utilized in intracranial imaging. The catheter is usually inserted in the groin, then advanced through the aorta. If the aorta is atherosclerotic, the chances of embolization to the extremities, renal arteries, and viscera are increased. Clinical trials have been done, none of which demonstrate that carotid stenting is superior to CEA. In select patients (i.e., those with recurrent stenosis after CEA or who have radiation to the neck), stenting may be a good option. The postoperative care is basically the same as for CEA. Additionally, the site used for vascular access needs to be monitored for swelling and bleeding. The extremity needs to be monitored for color, sensation, and movement. From a post-anesthesia care unit (PACU) perspective, patients are admitted to a critical care unit for overnight monitoring. Most patients are discharged on the first or second postoperative day.
