Abstract:
Objective To evaluate the clinical safety and efficacy of LVIS stent (a low profile knitting designed self-expandable stent) in assisting endovascular embolization for intracranial saccular aneurysms.Methods A total of 127 patients with intracranial saccular aneurysm,who were admitted to authors' hospital during the period from April 2014 to June 2016 to receive LVIS stent-assisted endovascular embolization,were retrospectively analyzed.The safety of the operation,the immediate postoperative outcomes,the recurrence rate,and the clinical and radiographic follow-up results were analyzed.Results A total of 130 LVIS stents were successfully implanted in the 127 patients with intracranial saccular aneurysm,implantation failure was seen in one patient,the technical success rate was 99.2％.During or after the endovascular embolization process in-stent thrombosis was observed in 7 patients (7/127,5.5％).Neither perioperative bleeding nor death occurred.Immediately after the operation,complete occlusion of the aneurysm was obtained in 112 aneurysms (88.1％) and neck remnant was observed in 15 aneurysms (11.9％).The patients were followed up for a mean period of 8 months.Follow-up angiography was performed in 37 patients,which showed that complete occlusion of the aneurysm was obtained in 33 patients (89.1％),and visualization of the aneurysm was seen in 4 patients (10.9％),including 3 patients who had aneurysm visualization immediately after embolization and one patient who had aneurysm recurrence.No death occurred.Conclusion The use of LVIS stent to assist endovascular embolization for intracranial saccular aneurysms is safe and effective,although its long-term effect needs further observation.
