Cardiopulmonary Monitoring during Graded Cervical Internal Carotid Artery Occlusion

Abstract

Abstract The intravascular volume and cardiac status of two patients who were thought to be at high risk to develop ischemic symptoms while undergoing graded cervical internal carotid artery occlusion were monitored by a dye dilution technique. Based on information obtained from this multivariable quantitative cardiopulmonary monitoring, measures were taken to maintain normo- to hypervolemia and to maximize cardiac performance. These medical adjuncts were thought to decrease the possibility of ischemic deficits while gradual occlusion of the internal carotid artery was being performed.
