ABSTRACT
Objective:To investigate the safety of the use of the intermediate catheter in the endovascular treatment (EVT) of patients with acute anterior circulation large vessel occlusive stroke and its impact on the outcomes.Methods:From May 2015 to September 2018, patients with anterior circulation large vessel occlusive stroke received EVT in Nanjing First Hospital, Nanjing Medical University were enrolled retrospectively. According to whether intermediate catheter was used during the procedure, they were divided into intermediate catheter group and non-intermediate catheter group. The demographics, clinical data and procedure related information were collected. The outcome evaluation indicators included secondary embolization, symptomatic intracranial hemorrhage, clinical outcome and death at 90 d after onset. A good outcome was defined as the modified Rankin Scale score of 0-2. Multivariate logistic regression analysis was used to determine the independent predictor of clinical outcome. Results:A total of 195 patients with anterior circulation large artery occlusive stroke received EVT were enrolled, including 161 in the intermediate catheter group and 34 in the non-intermediate catheter group. There were no significant differences in demographics and clinical characteristics between the intermediate catheter group and the non-intermediate catheter group. In terms of procedure related information, the number of mechanical thrombectomy passes in the intermediate catheter group was significantly decreased (2 [1-3] times vs. 2.5 [1.75-4] times; Z=2.218, P=0.017), the recanalization rate of one-pass thrombectomy was significantly higher (38.5% vs. 20.6%; χ2=3.943, P=0.047), and the rate of thrombus escape and secondary embolism was significantly lower (19.3% vs. 35.3%; χ2=4.202, P=0.041). In terms of clinical outcome, there were no significant differences in the incidence of symptomatic intracranial hemorrhage, mortality and good outcome at 90 d between the intermediate catheter group and the non-intermediate catheter group. Multivariate logistic regression analysis showed that the use of intermediate catheter was an independent predictor of good outcome at 90 d (odds ratio 0.430, 95% confidence interval 0.196-0.947; P=0.036). Conclusion:In EVT of patients with acute anterior circulation large vessel occlusive stroke, the use of intermediate catheter can reduce the number of mechanical thrombectomy passes, improve recanalization rate of one-pass thrombectomy, reduce the rate of thrombus escape and second embolization, and then improve the outcome of patients.
