Abstract: Objective To study the changes of ambulatory blood pressure parameters after endovascular treatment.Methods The ambulatory blood pressure of 7 patients with artery stenosis was tested before and after endovascular treatment,and the coefficient of variation(CV)was calculated.Results All patients' blood pressures decreased after endovascular treatment.The CV of blood pressure of patients with internal carotid stent decreased,but the CV of blood pressure in patients with vertebro-basilar artery stent increased.Conclusion The effects of stent on blood pressure is far from clear.
