Answers are grounded in this paper and cite their sources.
Performing carotid artery surgery without a temporary indwelling shunt does not appear to worsen stroke morbidity compared to historical outcomes with shunts.
One thousand nine hundred seventeen consecutive carotid artery operations were performed in which the carotid artery was clamped for as long as necessary to accomplish a revascularization procedure. Those patients adversely affected by failure to use a shunt were identified. Results of a statistical analysis of stroke morbidity when compared with the literature show that the use of an intraoperative temporary shunt does not offer improved results in carotid artery surgery.
