Abstract:

Objective

To analyze the influencing factors leading to incomplete recanalization of cervical artery dissection (CAD) by color Doppler flow imaging (CDFI).

Methods

A total of 105 patients with 126 CADs diagnosed at XuanWu Hospital, Capital Medical University from January 2014 to December 2018 were enrolled into this study. All patients were followed by CDFI at 3, 6, and 12 months after disease onset and were divided into either a complete recanalization group or an incomplete recanalization group according to the results at 12 months after the onset. The effect of factors such as age, cerebrovascular risk factors, arterial stenosis, and drug treatment on CAD recanalization were analyzed.

Results

Of the 126 dissected vessels, 54 (42.9%) were included in the incomplete recanalization group. Logistic regression analysis showed that age>45 years (OR=3.594, 95% CI: 1.430-9.033, P=0.007), history of hypertension (OR=3.037, 95% CI: 1.079-8.544, P=0.035), time from onset to treatment over one month (OR=3.135, 95% CI: 1.122-8.759, P=0.029), vascular occlusion (OR=7.381, 95% CI: 2.620-20.795, P=0.000) were independent risk factors for CAD recanalization; however, cause of CAD, extent of intramural hematoma, and anticoagulation or antiplatelet therapy were not factors affecting the incomplete recanalization of CAD (P>0.05).

Conclusion

Diagnosis and timely follow-up of CAD patients by CDFI to assess the correlation between the factors such as age, history of hypertension, timing of treatment, or stenosis of arterial lumen and recanalization are of important clinical significance.
