Efficacy of LVIS stent-assisted Target coil embolization in treatment of very small intracranial aneu-rysms:An analysis of 47 cases
Objective To investigate the efficacy of LVIS stent-assisted Target coil embolization in the treatment of very small intracranial aneurysms.Methods A retrospective analysis was performed for the clinical data and follow-up results of 47 patients with very small intracranial aneurysms who underwent LVIS stent-assisted Target coil embolization in our center from July 2015 to May 2023.Results For the 47 patients,angiography immediately after surgery showed dense embolization in 32 pa-tients(68.1％),residual aneurysm neck in 11 patients(23.4％),and partial embolization in 4 patients(8.5％).Perioperative com-plication was observed in 4 patients(8.5％),among whom 2 had intraoperative bleeding due to ruptured aneurysms(1 died and 1 had no obvious sequela after dense embolization),1 had intracranial infection after ruptured aneurysm surgery(with no neurolo-gical deficit after anti-infective therapy),and 1 had thrombosis during surgery(with no neurological deficit after the intraoperative application of tirofiban).Radiological follow-up examination was performed for 33 patients,among whom 29(87.9％)achieved complete embolization of aneurysms and 4(12.1％)had stable aneurysms.During follow-up,1 patient died due to temporal lobe hemorrhage after 14 days of discharge,while the other patients did not experience rebleeding.Conclusion LVIS stent-assisted Target coil embolization is safe and effective in the treatment of very small intracranial aneurysms,and therefore,it holds promise for clinical application.
