ABSTRACT
The common carotid artery is an artery which supplies the head and neck with oxygenated blood. Although unilateral common carotid artery occlusion or bilateral internal carotid artery occlusion have been reported, the incidence of both common carotid artery occlusion is very rare. As previous report which reviewed 5400 carotid duplex ultrasonograms, 2.5% of internal carotid artery occlusion, 0.24% of unilateral common carotid artery occlusion and none of bilateral common carotid artery occlusion were reported. Common carotid and subclavian arteries are important in the blood supply to the vasculatures of head and upper extremities. Bilateral common carotid artery occlusion might be a cause of stroke, transient ischemic attack or other neurologic sequalae. Cerebral oximetry is a simple method of measuring regional cerebral oxygen saturation (rSO2), which appears to reflect changes in cerebral perfusion and it has been increasingly applicated in many clinical situations such as vascular surgeries involving head/ neck and operations adopting cardiopulmonary bypass. This case describes a successful anesthetic management in a patient with occlusion of bilateral common carotid and subclavian arteries using continuous cerebral oxygenation monitoring during laparoscopic cholecystectomy.
