Abstract
Objective To investigate the diagnostic value of the combined transcranial Doppler ultrasound and CT for vertebrobasilar insufficiency in elderly patients. Methods Fifty elderly patients with symptoms of vertebrobasilar insufficiency were enrolled and randomly assigned to 4 groups, including examinations of TCD, CTA, DSA, combination of TCD and CTA. The diagnostic accuracy was calculated and compared. Results Among 50 cases, the vertebrobasilar insufficiency was confirmed in 42 patients (84%) by TCD, 45 (90%) by CTA, 48 (96%) by DSA, 49(98%) by combination of TCD and CTA. There was no significant difference in diagnostic rate between TCD combined with CTA and DSA (χ2=0.34, P>0.05). Conclusions The diagnosis accuracy of the combined CTA and TCD is high, making it worth popularizing. Key words: Ultrasonography, Doppler, transcranial; Computerized tomography, X-ray; Vertebrobasilar insufficiency
