Abstract:

[Abstract]   Objective   To assess the value of endoluminal convex array probe combined with high frequency linear
array probe in diagnosis of internal carotid artery occlusion, and to improve the diagnostic accuracy rate of ultrasonography.   Methods   Patients suspected with ischemic cerebrovascular disease (n=490) were examined by carotid ultrasound. First, suspicious patients with carotid artery occlusion were selected using high-frequency linear array probe, then screen results were confirmed by endoluminal convex array probe and compared with previous results in those patients.   Results   Sixty eight patients， who were suspected of internal carotid artery occlusion， were screened out by high-frequency linear array probe. Results were re-examined by endoluminal convex array probe, 42 patients were diagnosed as internal carotid artery occlusion, 19 patients were diagnosed as severe stenosis as the internal carotid artery and 7 patients were diagnosed as ca?rotid artery tortuosity with no significant stenosis. Conclusion   Endoluminal convex array probe is an effective complement for internal carotid arterial inspection when it combines with high-frequency linear probe. It can improve the diagnostic accuracy rate of degree and the range in internal carotid artery occlusion and stenosis, therefore reduce chances of misdiagnosis.
