Background: Mechanical thrombectomy undoubtedly improves functional outcomes for patients with acute ischemic stroke. Although we have observed occlusion sites that protrude proximally into the vessel on angiography, termed the “claw sign,” we have been unable to state its clinical significance. In this study, we aimed to determine whether the presence of a claw sign was related to recanalization success after mechanical thrombectomy. Materials and Methods: We retrospectively included 73 consecutive patients treated for acute cerebral large vessel occlusion by mechanical thrombectomy between January 2014 and December 2017. The angiographic claw sign was defined as a thrombus that protruded proximally by more than half the diameter of the parent artery. Claw sign positivity, clinical and etiological features, and outcomes were compared between groups with and without recanalization. Results: The claw sign was observed in 29 of 73 (40%) patients and was positive significantly more frequently in those with recanalization (50.0%) than in those without recanalization (5.9%) (P < .01). By multivariate analysis, the claw sign was the only pretreatment parameter to predict successful recanalization (odds ratio, 12.50; 95% confidence interval, 1.50-103.00; P = .019). Conclusions: The presence of the claw sign might predict successful recanalization in patients undergoing mechanical thrombectomy for large vessel occlusion. 相似文献

BACKGROUND Hepatocellular carcinoma(HCC) has become a great threat for people's health.Many long noncoding RNAs are involved in the pathogenesis of HCC.SNHG15,as a tissue specific long noncoding RNAs,has been studied in many human cancers,except HCC.AIM To explore the regulatory mechanism of SNHG15 in HCC METHODS In the present research,101 HCC patient samples,two HCC cell lines and one normal liver cell line were used.RT-qPCR and Western blot analysis were applied to detect SNHG15,miR-490-3 p and histone deacetylase 2(HD AC2)expression.The regulatory mechanism of SNHG15 was investigated using CCK8,Transwell and luciferase reporter assays.RESULTS Our research showed that up-regulation of SNHG15 was found in HCC and was related to aggressive behaviors in HCC patients.Moreover,knockdown of SNHG15 restrained HCC cell proliferation,migration and invasion.In addition,SNHG15 served as a molecular sponge for miR-490-3 p.Further,miR-490-3 p directly targets HDAC2.HD AC2 was involved in HCC progression by interacting with the SNHG15/miR-490-3 p axis.CONCLUSION In conclusion,long noncoding RNA SNHG15 promotes HCC progression by mediating the miR-490-3 p/HDAC2 axis in HCC. 相似文献
