Evaluation of Early Acute Cerebral Infarction with Transcranial Doppler

Objective:For patients with early acute cerebral infarction(ACI),transcranial Doppler ultrasound was used in the clinical examination,and its application effect was observed and analyzed.Methods:This study was carried out between October 2018 and October 2019.50 patients with ACI included as the research object was evaluated by transcranial Doppler and CT examination,and the application of the two examination methods was compared.Results:The results of transcranial Doppler examination showed that the abnormal rate of blood flow velocity and the ratio of both sides(VACA)in patients with early ACI was higher than that of CT examination.Conclusion:With the impact on the location and area of vascular occlusion in patients,VACA can effectively reflect the status and effectiveness of the collateral circulation function of the patient’s pia vessels during cerebral infarction.

Value of TCD foaming Test in Screening Patent Foramen Ovale in Migraine Patients and Efficacy of PFO Occlusion

Objective:To explore the effect of TCD foaming test in screening patent foramen ovale in migraine patients,as well as in the treatment effect.Methods:From September 2019 to August 2020,236 patients with migraine and 362 patients with normal physical examination were treated in our hospital.According to the random number table method,60 patients with migraine were selected as the observation group,and 60 patients with normal physical examination were selected as the control group.48 cases of PFO were confirmed by TCD foaming test Among the patients with migraine,36 patients received interventional occlusion therapy.The therapeutic effect and VAS score of the two groups were analyzed.Results:Through TCD foaming test,the proportion of PFO in the observation group was 80%,and that in the control group was 13.33%.The proportion of PFO in the observation group was significantly higher than that in the control group,and the difference was statistically significant(χ^(2)=53.5714,P<0.01);The symptoms disappeared in 30 patients and improved in 4 patients;Among the 36 patients who received interventional occlusion therapy,the VAS score of patients before and after the operation was significantly changed,and the proportion of patients whose pain disappeared after the operation was 83.33%,which was significantly lower than that before the operation,and the difference was comparable(χ^(2)=51.4286,P<0.01).Conclusion:TCD foaming test for PFO screening has strong applicability,not only safe and convenient,will not cause trauma to patients,and through interventional occlusion treatment,can significantly improve the clinical symptoms of migraine patients and cure patients.
