ABSTRACT
Objective To explore the changes and influencing factors of cerebral vasoreactivity (CVR) in patients after carotid angioplasty and stenting (CAS). Methods Thirty-seven patients performed CAS, admitted to our hospital from July 2008 to September 2009, were finished the follow-up and chosen in our study; the breath-holding index (BHI) of the bilateral middle cerebral artery was measured using transcranial Doppler combined with breath holding test before thc operation, and 1 d and 3-10 months after the operation. Repeated measures design analysis of variance was employed to detect the BHI changes before and after the stenting; multiple regression was employed to analyze the influencing factors of BHI. Results BHI values after stenting were significantly higher than those before stenting on the stenotic side (P<0.05). The follow-up BHI values were negatively correlated with those of tandem stenoses (β=-0.016, P=0.002) and positively correlated with the postoperative BHI values (β=1.030, P=0.000). Conclusion CAS can immediately improve CVR on the ipsilateral side and make it close to normalization gradually. Tandem stenoses are the independent risk factors of CVR.
