title: Carotid arteriospasm.
abstract: Arteriospasm can result from manipulation or fresh blood around an artery. This myogenic reflex can spread to obliterate collateral flow and can last from minutes to days. Ischemic strokes from carotid spasm ensue neurosurgical procedures, endarterectomies, and even chiropractic manipulation. The diagnosis and prevention of arteriospasm are presented, and a patient who has carotid arteriospasm following excision of a branchial cleft cyst is detailed. If the vessel constriction is noted at surgery, topical application of a local anesthetic is effective. Transfusion, hydration, oxygenation, and maintenance of blood pressure are the cornerstones of nonoperative therapy.
