Small ruptured and unruptured complex cerebral aneurysms: Single center experience of low-profile visualized intraluminal support stent

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.

Endovascular Treatment of Intracranial Aneurysms

“…However, a noticeable rate of thromboembolic events was observed. Similar observations were reported in further studies [49][50][51]. Correspondingly, a novel stent has been examined for its safety and efficacy, with promising outcomes and satisfactory safety [52][53][54][55][56].…”

The formation mechanism of acute dissection of blood blister-like aneurysm and its implication of endovascular treatment

“…Stenting across the ostia of BBLA and coiling of the aneurysm constituted typical endovascular treatment at our infirmary. Placement of novel LVIS and Pipeline flow-diverting stents with a braided-cell design exhibiting dense porosity (smaller holes in the wall of the stent compared with precedingly employed closedcell stents) across the ostia of BBLA proved safe and effective in our experience [25,26]. Feasibility of surgical or endovascular reconstruction of segments of the parent vessels of BBLA appears to constitute a method preferentially recapitulating physiological flow through the ICA.…”

Compatibility of the semijailing technique with extremely soft i-ED coils for ruptured blood blister–like and dissecting aneurysms: patient series

“…7,8 LVIS stents may be used safely and effectively even immediately after rupture. [9][10][11][12] Although flow-diverting stents for BBAs or ruptured DAs represent a treatment option, they require some time for endothelialization. The use of a braided stent and low-memory shape coils may achieve immediate hemostasis without increasing bleeding during the procedure.…”
