ABSTRACT
Objective To study the preoperative ultrasonographic parameters and their relationship with age in symptomatic CAS patients with different curative effects of stenting.Methods Fiftyseven symptomatic CAS patients admitted to our hospital for stenting were divided into young age group (n=7),middle age group (n=25),old age group (n=25) according to their age,and into very good curative effect group (n=18),good curative effect group (n=33) and no curative effect group (n=6) according to their postoperative NIHSS score.The carotid ultrasonographic parameters in different groups were compared and analyzed within 3 days before operation.Results A significant difference was found in the ratio of UPT,maximal ER of plaques,PV of stenosis,PI,resistance index (RI),carotid artery stiffness index (SI),distensibility coefficient (Dc) and compliance coefficient (Cc) in different curative effect groups (P<0.01).The carotid artery SI was significantly higher in old age group than in young age group and middle age group (P<0.01).A linear regression equation was established between carotid stiffness and age (y=0.075x-1.537,R2 =0.448,F=44.727,P =0.000).Conclusion The ratio of UPT,maximal ER of plaques,PV of stenosis,PI,RI,carotid artery SI,Dc and Cc are different in patients with different curative effects of stenting,and a linear relationship is found between carotid artery SI and age of patients.
