Microcoils embolization for the treatment of intracranial wide-necked aneurysms under LVIS stent assistance in elderly patients

Abstract

Objective To summarize operation experiences in applying microcoils embolization for the treatment of intracranial wide-necked aneurysms using the low-profile visualized intraluminal stent support (LVIS) in elderly patients. Methods We reviewed data of 47 elderly patients (48 aneurysms) with intracranial wide-necked aneurysms treated with LVIS stent-assisted microcoils embolization. Results Forty-seven aneurysms were embolized successfully, one stent was withdrawn because its midpiece failed to stretch.Instant Raymond classifications evaluation after the surgery showed Grade Ⅰ in 52.1% (25/48 aneurysms), Grade Ⅱ in 37.5% (18/48 aneurysms), and Grade Ⅲ in 8.3% (4/48 aneurysms). Besides, the effective rate of aneurysms embolization was 91.5%.During 3-to 12-month follow-up with digital subtraction angiography (DSA) in 36 patients (36 aneurysms), mRS was scored 0 (best effectiveness) in 28 cases, scored 1 in 4 cases, scored 2 in 3 cases, and scored 3 in 1 case, and the total favorable rate was 97%. Conclusions LVIS stent-assisted microcoils embolization for the treatment of intracranial wide-necked aneurysms in elderly patients may avoid or reduce the incidence of complication.
