Abstract

Objectives:

Even though low-profile visualized intraluminal support (LVIS) device is used extensively currently and provide intraluminal support in complex cerebral aneurysm embolization, only few studies have reported its clinical results. This study presents the results of patients treated with LVIS.

Patients and methods:

Cerebral aneurysms with an undefined neck, fusiform shape, and blood blister-like aneurysms that were treated with LVIS between May 2017 and May 2019 were reviewed retrospectively.

Results:

Overall, 112 aneurysms in 104 patients were treated using LVIS, and 105 LVISs were placed. Of these, 101 aneurysms (90%) were small (< 10 mm) in size, 17 were fusiform aneurysms, and 3 were blood blister-like aneurysms. Overall, 39 patients suffered a subarachnoid hemorrhage and 65 had no bleeding history. 2 patients died of internal carotid artery (ICA) thrombosis, resulting in 1.9% mortality rate. Follow-up angiography was obtained in 68 patients (65%), and the complete obliteration rate was 98.5% in 6–12 months.

Conclusion:

The LVIS is a safe and effective treatment for small ruptured or unruptured complex intracranial aneurysms.
