Abstract
Objective To investigate the effect of CT angiography combined with CTP in the diagnosis of acute cerebral infarction complicating by cerebral vascular stenosis in the elderly and its effect on prognosis.Methods 30 elderly patients with acute cerebral infarction and cerebrovascular stenosis were enrolled in this study from May 2015 to July 2017.The patients received cranial CT scan,CT perfusion imaging (CTP),CT angiography (CTA),cerebral blood flow (CBF) and cerebral blood volume (CBV) in the lesion area,perifocal area,contralateral area were measured.30 elderly patients with acute cerebral infarction and cerebrovascular stenosis were followed up for 12 months,the prognosis of patients was recorded.Results In 30 elderly patients with acute cerebral infarction and cerebrovascular stenosis,CBF and CBV in the lesion area were significantly lower than those in the perifocal area and contralateral area (P＜0.05),CBF in the perifocal area was higher than that in the contralateral area (P＜0.05),CBV in the perifocal area was lower than that in the contralateral area (P＜0.05);the average passage time in the lesion area was shorter than that in the perifocal area,but longer than that in the contralateral area (P＜0.05),the average passage time in the perifocal area was longer than that in the contralateral area (P＜0.05).A total of 43 stenosis were detected by CT angiography,13.95％ of which were severe stenosis,58.14％ of moderate stenosis,27.19％ of mild stenosis.CTP perfusion abnormalities were consistent with stenosis of arterial blood supply in 26 cases,with the coincidence rate of 86.67％,with good agreement rate.After treatment,the good recovery rate was 63.33％ and the disability rate was 16.67％.Conclusion CT angiography combined with CTP has ideal results in elderly patients with acute cerebral infarction and cerebral vascular stenosis,is worth promoting the application.关键词
