Abstract:
Objective To analyze the imaging characteristics and to evaluate the application value of color doppler ultrasonography (CDUS)combined with CT angiography (CTA)and contrast-enhanced magnetic resonance angiography (CE-MRA)in patients with cervical vertigo.Methods 62 patients diagnosed with cervical vertigo clinically were enrolled.Neck CDUS and neck CTA were per-formed on 39 patients.Neck CDUS and neck CE-MRA were performed on 23 patients.Neck CDUS and CTA/MRA were performed on 30 normal volunteers,which were chosen as control group.Neck CDUS and neck CTA were performed on 18 normal volunteers. Neck CDUS and neck CE-MRA were performed on 12 normal volunteers.Hemodynamics and morphology were evaluated and com-pared between the two groups.Results In aspect of morphology:The incidence of vertebral artery (VA)stenosis (46.77%)and VA variation (29.03%)in cervical vertigo group were higher than VA stenosis (23.33%)and VA variation (6.67%)in control group with significant difference (all P <0.05).The incidence of tortuous VA showed no statistics difference between cervical vertigo group (1 1.29%)and control group (13.33%)(P >0.05).In aspect of hemodynamics:The decline incidence of peak systolic velocity de-tected by CDUS in cervical vertigo group (66.13%)was higher than that in control group (10.00%)with statistically significant difference (P <0.05).The peak systolic velocity decline incidence of VA stenosis (86.21% )and VA variation (72.22%)were high-er than that of VA tortuous (28.57%)and VA normal (12.50%)patients in cervical vertigo group.Conclusion The application of CDUS combined with CTA or CE-MRA could provide valuable diagnostic and therapeutic information for cervical vertigo in the as-pects of change in vascular morphology and cerebral hemodynamics,which could further provide objective basis for clinical diagnosis and treatment.
