Abstract:
Objective:To explore the application value of guide tube fenestration and drainage technology in intracranial artery stenting surgery.Methods:A total of 120 patients with symptomatic intracranial atherosclerotic stenosis admitted to the Xingtai Third Hospital from January 2021 to December 2022 were selected and randomly divided into an observation group ( n=60) and a control group ( n=60). Both groups were treated with intracranial artery stenting, with the observation group receiving guidance catheterization and window opening technique during the surgery. Two groups of surgeries were observed and compared: the degree of vascular stenosis before and after surgery, the Montreal Cognitive Assessment Scale (MoCA) scores before and one month after surgery, intraoperative complications, and prognosis. Results:The surgical time and catheter placement time in the observation group were (110.20±23.32)minutes and (11.32±2.01)minutes, respectively, which were significantly shorter than those in the control group (all P<0.05). The stent placement rate and operation success rate in the observation group were 95.00% and 96.67%, respectively, significantly higher than those in the control group (all P<0.05). The degree of postoperative vascular stenosis in the observation group was (32.29±7.11)%, significantly milder than that in the control group [(44.43±8.15)%, P<0.05]. One month after surgery, the MoCA scores of both groups improved significantly compared to before surgery (all P<0.05), and there was no statistically significant difference between the groups ( P>0.05). There was no statistically significant difference in the incidence of collateral circulation occlusion and vascular rupture between the two groups (all P>0.05). During the follow-up period, there was no statistically significant difference in the incidence of restenosis, intracranial hemorrhage, and recurrent ischemic stroke between the observation group and the control group (all P>0.05); The good prognosis rate of the observation group was 73.33%, significantly higher than that of the control group (53.33%, P<0.05). Conclusions:The application of guided catheter fenestration technique in intracranial artery stenting has good value, which is beneficial for improving the stent placement rate and operation success rate, and improving the degree of vascular stenosis.
