Objective To investigate the impact of collateral circulation on neurological function and prognosis outcome of patients with acute cerebral infarction. Methods Assessed the collateral circulation of 274 patients with acute cerebral infarction from June 2012 to April 2015 in the department of neurology in Worker′s Hospital of Wuzhou using DSA, analyzed patients′ neurological function and prognosis outcome concerning their collateral circulation. Results (1) Impairment of neurological function were different between collateral circulation group and non-collateral circulation group ( P < 0 . 05 ) , but there was no significant difference in neurological impairment between the primary collateral circulation and secondary collateral circulation (P > 0.05). (2)14 and 90 days after treatment, symptoms of neurological impairment in posterior communicating artery, before pial artery, after pial artery and combination artery were significantly improved as with their NIHSS scores (P<0.05). However, symptoms of neurological impairment in anterior communicating artery, arteria ophthalmica and non-collateral circulation did not significantly improved at 14 and 90 days after treatment, with no significantly different NIHSS score (P > 0.05). Conclusions (1) Neurological function of patients with collateral circulation was better without collateral circulation. Grading of collateral circulation had did not relate to neurological function. (2) Prognosis of patients with collateral circulation was improved significantly than the patients without collateral circulation. The types of collateral circulation affect the prognosis of the patients with acute cerebral infarction.

Objective To investigate the effectiveness and safety of EVT in mild stroke patients with ALVO.Methods A total of 124 mild stroke patients with ALVO treated in our hospital were enrolled and randomly divided into control group(n=64)and observation group(n=60).The control group was given routine treatment,while the observation group received EVT treat-ment besides routine treatment.NIHSS score,BI score,and mRS score were compared between the two groups to evaluate the postoperative safety of EVT treatment.Results The NIHSS scores on the 7th and 14th days,and at discharge were significantly lower in the observation group and control group than those at admission(P<0.05),and those of the former group were obvi-ously decreased than those of the latter group at the corresponding time points(P<0.01).On the 7th,14th,and discharge days,the BI score of both groups were significantly increased compared to those at admission(P<0.05),with the scores in the observation group higher than those of the control group at above time points(P<0.01).The ratio of the patients having mRS score ≤2 point was larger in the observation group than the control group(96.67%vs 84.38%,P<0.05).One case in the observation group experienced asymptomatic intracranial hemorrhage,and no oth-er adverse events were observed.Conclusion EVT can improve the prognosis of mild stroke pa-tients with ALVO,but does not significantly increases the incidence of adverse events.

Objective:To analyze the clinical efficacy and safety of stent implantation combined with drug therapy and drug therapy alone in patients with vertebral artery initial stenosis.Methods:A total of 112 patients with vertebral artery initial stenosis who were treated in Wuzhou Workers′ Hospital from January 2016 to June 2018 were selected and divided into drug group and stent + drug group according to random number table method, with 56 patients in each group. The drug group received drug therapy alone, and stent + drug group received stent implantation combined with drug therapy. The incidence of ischemic events in posterior circulation, the improvement of vascular stenosis rate and the improvement of neurological function injury were observed in the two groups after 12 months of treatment.Results:The success rate in the stent + drug group was 100.0%(56/56). The rate of vascular stenosis in the stent + drug group was lower than that in the drug group: (15.21 ± 3.74)% vs. (18.62 ± 4.27)% ; but the incidence of restenosis was higher than that in the drug group:26.79%(15/56) vs. 7.14%(4/56), the differences were statistically significant ( P<0.05). The total incidence of ischemic events in the posterior circulation after treatment in the stent + drug group was lower than that in the drug group: 8.93%(5/56) vs. 28.57%(16/56), and the difference was statistically significant ( χ2 = 7.092, P = 0.008). After treatment, the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (MRS) in the stent + drug group were lower than those in the drug group: (2.30 ± 0.36) scores vs. (3.75 ± 0.52) scores, (4.11 ± 0.51) scores vs.(6.14 ± 0.57) scores, and the differences were statistically significant ( P<0.05). Conclusions:The application of stent implantation combined with drug regimen in the treatment of patients with vertebral artery initial stenosis can effectively reduce the neurological damage of patients, andimprove the total effective rate, which is conductive to the improvement of patients′ quality of life, but the rate of stent restenosis is high.
