Abstract
Objective To investigate the relationship between cortical watershed infarction and carotid artery stenosis and evaluate the stent insertion operation.Methods After 23 cortical watershed infarction patients diagnosed by CT or MRI received DSA detection,we performed stent insertion operationon 11 patients according to their requirements,and conservative treatment on the remaining 12 patients.All the patients underwent follow up for 6-12 months post-operatively.Results Among the 23 cortical watershed infarction patients,22 Were detected with carotid artery stenosis.Statistical analysis showed that the degree of carotid artery stenosis was associated With the elinical svmDtoms and the volume of steal phenomenon(P<0.05);further,the artery stenosis improvement was over 90%with the stent inserted;conversely,dizziness and steal phenomenon disappeared.The post procedure follow-up,ranging 6-12 months,showed that the patients with stent insertion got less new symptoms,steal phenomenon and artery stenosis,compared with the patients with conservation treatment(P<0.05).Conclusion Cortical watershed infarction is associated with carotid artery stenosis.The stent insertion iS useful for the treatment ofcarotid artery stenosis and prevention of cortical watershed infarction.
Key words:
Cerebral watershed infarction; Carotid artery stenosis; Stent insertion; Follow-up control study
