高频线阵探头联合腔内凸阵探头诊断颈内动脉闭塞的价值

Values of High Frequency Linear Array Probe Combined with Endoluminal Convex Array Probe in Diagnosis of Internal Carotid Artery Occlusion

目的探讨超声高频线阵探头与腔内凸阵探头联合应用诊断颈内动脉闭塞的临床价值,提高超声诊断的准确率。方法对490例临床怀疑缺血性脑血管病患者进行颈动脉超声检查。先以高频探头筛查出可疑颈内动脉闭塞患者,再以腔内凸阵探头进行复检,对比观察2种探头的检测结果。结果高频线阵探头筛查出可疑颈内动脉闭塞患者68例,经腔内凸阵探头复检,诊断颈内动脉闭塞者42例,颈内动脉重度狭窄者19例,颈内动脉走行深在迂曲无明显狭窄者7例。结论腔内凸阵探头可作为颈内动脉检查的有效补充手段,与高频线阵探头联合应用,能够更准确地诊断颈内动脉闭塞及狭窄的程度和范围,减少误诊。

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 carotid 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.
