Abstract Objective: To investigate the relationship between intracranial and extracranial atherosclerotic stenosis by using transcranial doppler (TCD) and carotid artery ultrasound. Methods: A total of 186 patients with coronary artery stenosis confirmed by coronary angiography in our hospital were divided into group A, 97 cases (coronary artery stenosis ≤ 2 branches) and group B, 89 cases (coronary artery stenosis ≥ 3 branches). Patients in both groups were examined by transcranial Doppler ultrasound (TCD) and carotid artery ultrasound. The stenosis of intracranial artery (group A: 1067, group B: 979), extracranial artery (group A: 776, group B: 712) were compared between the two groups.Results: The detection rates of intracranial and extracranial arterial stenosis were 5.2% (55 / 1067) and 10.18% (79 / 776) in group A, and 8.5% (83 / 979) and 17.13% (122 / 712) in group B, with statistical significance (P=0.003, P=0.001). In group A, 52 (39%) were mild stenosis, 47 (35%) were moderate stenosis, 35 (26%) were severe stenosis or occlusion; 61 (30%) were mild stenosis, 65 (32%) were moderate stenosis, 79 (38%) were severe stenosis or occlusion. The difference between the two groups was statistically significant (P=0.018). Conclusion: In patients with coronary heart disease, with the aggravation of intracranial and extracranial artery stenosis, the severity of coronary artery stenosis and the number of involved vessels are also increasing, and the two are positively correlated. We can evaluate coronary artery stenosis by examining intracranial and extracranial artery stenosis with integrated carotid brain ultrasound (TCD and carotid ultrasound).
