A Retrospective Study Of LVIS Stent-assisted Coil Embolization Of Intracranial Aneurysms

Objective:To observe the safety and effectiveness of LVIS-assisted coil embolization of intracranial aneurysms by observing LVIS stent-assisted coil embolization.To provide theoretical basis for the clinical application of LVIS stent-assisted coil in the treatment of intracranial aneurysms.Methods:Select the patients: Patients were enrolled between 2014 and 2016,58 cases of intracranial aneurysms treated with neurovascular therapy in the First People 's Hospital of Jining City,Shandong Province.The clinical data,imaging data,complications,treatment,follow-up data were collected and collected from all patients treated.Look back and anaiyze the clinical materials of cases of aneurysm emboiotherapy in different departments and cases of different types of aneurysm emboiotherapy.The safety and efficacy of LVIS stent-assisted coil embolization of intracranial aneurysms were evaluated by retrospective analysis of clinical data,imaging data,therapeutic effect and follow-up data of all patients.Results:Immediately evaluation with Raymond standard assessment,all aneurysms completely embolism,95% to 99% complete embolism 2,less than 95% incomplete embolization 0.The neck of aneurysms in the immediate embolization degree no significant statistical difference(P>0.05).Perioperative complications occurred in 7 cases,intraoperative rupture bleeding occurred in 2 cases,intraoperative thrombosis in 1 case,the shift of the stent in 1 case,hydrocephalus 3 cases.The overall incidence of complications was 13.0%.Broad neck and narrow neck aneurysms perioperative complications,no significant statistical difference(P>0.05),hypertension incidence of perioperative complications no significant statistical difference(P > 0.05).Rankin improved prognostic score(MRS score)to evaluate hospital outcome,0 to 2 grade 50 cases,3-6 points,4 cases.During the follow-up period of 3 to 12 months,both by DSA review,including 2 cases of recurrence.The prognosis of patients with and without hypertension and recurrence rates between no significant statistical difference(P>0.05),the prognosis of wide and narrow neck aneurysm neck and recurrence rates between no significant statistical difference(P>0.05).Conclusion:The LVIS stent is a safe and effective device for stent-assisted coiling,it suitable for different parts of aneurysms,the LVIS stent have a good therapeutic effect for the traffic aneurysms and dissecting aneurysms and so on.High blood pressure for the prognosis of LVIS stent assisted coil embolization of intracranial aneurysms have no influence.LVIS stent assisted coil embolization of intracranial wide neck and narrow neck aneurysm embolization degree and recurrence rate has no obvious difference.
