Quantification of arterial and venous blood flow parameters in patients with carotid atherosclerosis before and after carotid endarterectomy

The aim of the study was to quantify the arterial and venous blood flow parameters by ultrasound in patients with atherosclerosis of the carotid artery before and after carotid surgery, at rest and during stress-tests. The clinical group comprised 52 patients with hemodynamically significant stenoses of internal carotid arteries. The control group included 14 healthy volunteers. The parameters were quantified at rest and during the functional tests, before operation, and in the early period (7-10 days) after carotid endarterectomy. The results suggest that comprehensive arterial and venous ultrasonography provides adequate control of cerebral hemodynamics and cerebrovascular reserve follow-up in the course of carotid endarterectomy.
