ObjectivesTo review the efficacy and safety of mechanical thrombectomy in patients with cerebral venous sinus thrombosis (CVST).MethodsWe searched The Cochrane Library, PubMed, EBSCO, Web of Science, CBM, CNKI and VIP databases to collect studies on mechanical thrombectomy in CVST patients from inception to April, 2018. Two reviewers independently screened literature, extracted the data and qualitative analysis of the included studies.ResultsA total of 33 studies including 552 patients were included for data analysis. Specifically, 157 (30%) patients had a focal neurological deficit, 145 (28%) patients had a pretreatment intracerebral hemorrhage or infarct, and 152 (29%) patients were stuporous or comatose. Wire was the most commonly used device. Overall, 483 (88%) patients had good outcome, while 35 (6%) patients deceased. Moreover, 333 (65%) patients had complete recanalization, 148 (29%) patients had partial recanalization, and 14 (2.5%) patients had worsen or new intracranial hemorrhage.Conclusions The current evidence suggests that mechanical thrombectomy is reasonably safe in the majority of cases. Due to limited quality and quantity of included studies, more high quality studies are required to verify above studies.
ObjectivesTo systematically review the efficacy and safety of mechanical thrombectomy for patients with acute ischemic stroke in different ages.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) on the efficacy and safety of mechanical thrombectomy for patients with acute ischemic stroke in different ages from inception to August, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 13 studies involving 2 995 patients were included. The results of meta-analysis showed that compared with the control group, patients aged 80 and above had no statistically significant difference in reperfusion success rates (OR=0.90, 95%CI 0.71 to 1.14, P=0.378), and incidence of symptomatic intracranial hemorrhage (OR=1.30, 95%CI 0.86 to 1.94, P=0.212), however, with higher incidence of arbitrary intracranial bleeding events (OR=1.61, 95%CI 1.28 to 2.04, P<0.001), 3-month mortality (OR=2.14, 95%CI 1.73 to 2.64, P<0.001) and lower good functional prognosis rate at 3 months (OR=0.46, 95%CI 0.30 to 0.71, P<0.001).ConclusionsCurrent evidence suggests that people aged 80 and above can obtain effective perfusion through mechanical thrombectomy, however, the incidence of postoperative adverse outcome events is higher and the prognosis is relatively poor. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Stroke is a disease that seriously affects the quality of life of patients. Its main characteristics are that the incidence rate is increasing year by year, the risk of death is high, and the prognosis of the disease is poor. For patients with acute cerebral artery occlusive ischemic stroke, intravenous thrombolysis alone has a low recanalization rate and poor long-term prognosis. With the development of interventional treatment technology for cerebrovascular disease, intravascular interventional treatment methods such as arterial thrombolysis, stent placement, and mechanical thrombectomy are more and more applied in the ultra-early stage of acute ischemic stroke. This article reviews the progress of mechanical thrombectomy in the treatment of cerebral artery occlusion in patients with acute ischemic stroke.
Objective To explore the impact of gender difference in 90-day outcomes after mechanical thrombectomy for acute cerebral infarction. Methods A prospective registration, observational, and retrospective analysis study was carried out. Patients with acute cerebral infarction who were admitted to the Department of Neurology of the First Affiliated Hospital of Chengdu Medical College and the Department of Neurology of Nanjing First Hospital between June 2015 and June 2019 were collected. Patients were divided into two groups based on gender. The detailed demographic, laboratory examination, imaging examination and clinical data were collected. Then, the data were analyzed using univariate and multivariate logistic regression analyses. Results A total of 298 patients were included. Among them, there were 185 males and 113 females. The differences in age, smoking, atrial fibrillation, using antiplatelet drugs before stroke, TOAST classification, and involved cerebrovascular sites between the two groups were statistically significant (P<0.05), and there was no statistically significant difference in other baseline data between the two groups (P>0.05). The results of univariate logistic regression analysis showed that the rate of 90-day favourable outcome of female patients was lower than that of male patients [odds ratio (OR)=0.462, 95% confidence interval (CI) (0.275, 0.775), P=0.030]. The results of multivariate logistic regression analysis showed that, after adjusting for confounding factors, there was no independent correlation between gender and the 90-day favourable outcome of patients with acute cerebral infarction who underwent mechanical thrombectomy [OR=1.511, 95% CI (0.745, 3.066), P=0.253]. Conclusion The gender has no significant effect on the 90-day favourable outcome of acute cerebral infarction patients treated with mechanical thrombectomy.
