Abstract: Objective To explore the therapeutic effect of dual microcatheter technology on patients with intracranial wide necked aneurysms and its impact on their neurological function.Method This article adopts a prospective randomized controlled study,collect clinical data of 55 patients with intracranial wide neck aneurysms from the First People's Hospital of Suzhou City from March 2017 to March 2022.According to different treatment methods,divided treatment group 28 cases and control group 27 cases.The control group patients received stent assisted therapy,while the treatment group patients received dual microcatheter intervention therapy.Compare efficacy and complications two groups;changes in NIHSS score and ADL score before and 6 months after surgery;Postoperative prognosis at 6 months.Result The total effective rate of the treatment group was 100.00%,while the total effective rate of the control group was 96.30%;two groups of patients with intracranial wide necked aneurysms treatment efficacy no significant difference (P>0.05).The treatment group complications in patients with intracranial wide necked aneurysms (7.14%) less control group (33.33%) (P<0.05).The two groups NIHSS score of patients with intracranial wide necked aneurysms lower before surgery at 6 months after surgery,while the ADL score higher before surgery (P<0.05);the treatment group NIHSS score of patients with intracranial wide necked aneurysms (8.76±0.87) score lower control group (9.82±0.96) score after 6 months of treatment,while the ADL score (57.82±5.43) score higher control group (64.52±5.16) score (P<0.05).There was no significant difference in mRS Scores between the two groups(P>0.05).Conclusion The dual microcatheter technology has a good therapeutic effect on IWNA patients,can reduce the occurrence of complications,improve patient neurological function.
