Abstract:
Objective:To evaluate the application value of transcranial Doppler in the detection of intracranial artery stenosis in patients with cerebral infarction.Methods:120 patients with cerebral infarction who received treatment in Zhuji Hospital of Traditional Chinese Medicine from December 2018 to December 2020 were included in this study. The patients underwent CT angiography and transcranial Doppler examination. The results of CT angiography and transcranial Doppler examination for screening intracranial artery stenosis at different locations were evaluated. Taking CT angiography results as the gold standard, the efficacy of transcranial Doppler examination for screening intracranial artery stenosis at different locations was determined. The consistency of transcranial Doppler examination versus CT angiography in screening intracranial necrosis at different locations was evaluated. Results:The sensitivity of transcranial Doppler examination in the detection of intracranial artery stenosis at bilateral middle cerebral arteries, anterior cerebral artery, posterior cerebral artery, basilar artery, bilateral vertebral arteries, and internal carotid artery (Siphon segment) was 89.47%, 91.18%, 85.00%, 90.62%, 81.82%, 96.55%, respectively. The specificity of transcranial Doppler examination in the detection of intracranial necrosis at bilateral middle cerebral arteries, anterior cerebral artery, posterior cerebral artery, basilar artery, bilateral vertebral arteries, and internal carotid artery (Siphon segment) was 87.30%, 95.35%, 91.25%, 94.32%, 96.33%, and 87.88%, respectively. The Kappa value for judging the consistency between transcranial Doppler examination and CT angiography in the detection of intracranial artery stenosis at bilateral middle cerebral arteries, anterior cerebral artery, posterior cerebral artery, basilar artery, bilateral vertebral arteries, and internal carotid artery (Siphon segment) was 0.766, 0.858, 0.758, 0.833, 0.800, and 0.852, respectively.Conclusion:Transcranial Doppler examination has high sensitivity and specificity in the detection of intracranial artery stenosis at different locations. Its screening results are highly consistent with those from CT angiography. Transcranial Doppler examination is of high clinical application value.
