Endovascular treatment of wide-neck anterior communicating artery aneurysms using the LVIS Junior stent

We performed this retrospective study to assess the clinical safety and efficacy of the low-profile visualized intraluminal support junior (LVIS Jr.; MicroVention, Aliso Viejo, CA, USA) stent placement in anterior communicating artery (ACA) aneurysms. ACA aneurysms are some of the most common intracranial aneurysms. Stent placement is particularly difficult due to the complexity of the vascular anatomy and the small vessels of the ACA complex. From November 2013 and June 2014, LVIS Jr. stent-assisted coiling was performed in 11 patients with 12 wide-neck ACA aneurysms. Patient demographics, morphologic features of the aneurysm, clinical results and follow-up results are presented. Successful deployment of the LVIS Jr. stent in the targeted artery was achieved in all patients. Complete occlusion was achieved in seven patients, neck remnant in three, and partial occlusion in two. The angiographic follow-up of nine patients (mean 4.4 months) showed that all aneurysms remained stable or improved. There was no in-stent stenosis, recurrence or retreatment. The modified Rankin scale score at discharge was 0 in eight patients and 1 in three patients. The LVIS Jr. stent provided excellent trackability and deliverability and is safe and effective for the treatment of wide-necked ACA aneurysms. Further follow-up is needed to assess the long-term efficacy of LVIS Jr. stent placement in ACA.
