Abstract

Objective. Optimize the ultrasonic scanning of veins and arteries of carotid bed in patients with atherosclerotic lesions of the brachiocephalic arteries allocated for the operation of carotid endarterectomy.

Material and methods. The study included 90 patients with atherosclerotic lesion of arteries of the carotid bed. The group of patients who had more than 60% stenosis degree have undergone endarterectomy from the internal carotid artery in the period from 2011 to 2013. All patients were divided into three groups: the first group included 30 patients with stenosis of the brachiocephalic arteries up to 40%, the 2nd group – 30 patients with stenosis of the brachiocephalic arteries ranged from 40% to 60%. The third group consisted of patients with more than 60% stenosis of the brachiocephalic arteries, and who had persistent clinic transient ischemic attacks. Complex assessment of arterial and venous circulation by ultrasonic scanning have been performed in patients of all groups. It also evaluated such quality signs as headache, tinnitus, dizziness, and gender.

Results. It is established that in cases of severe atherosclerotic lesions of carotid arteries (CA) affects not only the arterial, but also venous circulation. At we studied qualitative characteristics the most pronounced relationship with the percentage of stenosis have such signs as tinnitus, dizziness, and gender. There is a violation of the relationship between linear blood flow velocity (LBFV) of the CCA and IJV. So does the increase in speed performance in IJV and vertebral veins (VV) in clinostasis, without significant increase in LBFV in that veins in orthostasis and preservation of the pulsatile nature of blood flow, which suggests impaired venous outflow.

Conclusion. In the present study it is established that with increase of the degree of stenosis, there was a significant increase in systole-diastolic ratio in CCA, which confirms the increase in the degree of stenosis in the distal common carotid artery (CCA bifurcation) and ICA. The speed of venous blood flow indices in IJV and VV also increasing in clinostasis, without a significant increase of LBFV in that veins in orthostasis, which may indicate the severity of venous outflow disorders.
