Application of Combined 8F Guide Catheter Suction with Other Thrombectomy Techniques in Patients with Acute Internal Carotid Artery Occlusion / 中风与神经疾病杂志

ABSTRACT

@#Objective　To investigate the effectiveness and safety of 8F guide catheter combined with other thrombectomy techniques in the thrombectomy treatment of patients with acute internal carotid artery occlusion. Methods　From January 2016 to November 2019，we retrospectively analyzed 52 patients data from the Department of Neurology，Guangdong Provincial People’s Hospital，those patients were diagnosed as acute internal carotid artery occlusion results from cardiac cerebral embolism and treated with mechanical thrombectomy. They were divided into observation group and control group in according to whether suction treatment in combination with 8F guide catheter was conducted. Data collected and analyzed between the two groups included age，gender，hypertension，diabetes，Alberta Stroke Program Early CT（ASPECT） score，the United States National Institutes of Health Stroke Scale（NIHSS）score，bridging treatment，onset to puncture time （OTP），puncture to recanalization time （PTR），mechanical thrombectomy technique，number of thrombectomy maneuvers，vascular recanalization，asymptomatic intracranial hemorrhage （aSICH），symptomatic intracranial hemorrhage （SICH），mRS at 90 days after endovascular thrombectomy. Results　（1）There were no statistically significant differences in baseline data between the two groups of patients （P>0.05）. （2）There were no statistically significant differences in bridging treatment，OTP，PTR，mechanical thrombectomy technique，aSICH and SICH between the two groups of patients （P>0.05）. The average times of thrombectomy in the observation group and the control group were 2.1 and 3.0 respectively，and the difference between the two groups was statistically significant （P=0.009）. In the observation group，23 cases had successful recanalization，17 cases had good mRS prognosis 90 days after operation，and 11 cases in the control group had successful recanalization，and 7 cases had a good prognosis at 90 days after operation. The difference between the two groups was statistically significant （P<0.05）. Conclusion　For patients with acute internal carotid artery occlusion results from cardiac cerebral embolism，the application of 8F guided catheter suction combined with other thrombectomy techniques can improve the effect of thrombectomy. It is a method of mechanical thrombectomy with clinical value.
