Abstract:
Objective: To investigate the ultrasonographic manifestations of cervical artery dissection and analyze the causes of missed diagnosis. Methods: Ultrasound images of 28 patients with cervical artery dissection diagnosed by high-resolution MRA/CTA/DSA were retrospectively analyzed, and the sonographic features of cervical artery dissection were observed, and the causes of missed ultrasound diagnosis were analyzed. Results: In the 28 cases of cervical artery dissection, 15 cases were clearly diagnosed by ultrasound, 13 cases were missed diagnosis by ultrasound, the diagnostic coincidence rate was about 53.57% (15/28), and the missed diagnosis rate was 46.43% (13/28). Ultrasonographic manifestations of cervical artery dissection were in 15 cases including "double lumen sign" in 7 cases, intramural hematoma in 6 cases, occlusion or severe stenosis in 2 cases. In the 15 patients, 15 had abnormal blood flow and 7 had abnormal spectrum. In the 13 cases of missed ultrasonic diagnosis, 6 cases were negative, 7 cases only were reminded severe stenosis or occlusion and abnormal frequency spectrum. Conclusion: "Double lumen sign" and intramural hematoma are common manifestations of cervical artery dissection. Young and non-atherosclerotic patients should be highly alert to cervical artery dissection in the presence of severe carotid artery stenosis or occlusion and hemodynamic abnormalities.
