Dual Stenting Using Low-Profile LEO Baby Stents for the Endovascular Management of Challenging Intracranial Aneurysms

Abstract

BACKGROUND AND PURPOSE: Endovascular treatment of wide-neck, complex, and distally located cerebral aneurysms is a challenging issue. This study evaluated the safety and efficacy of dual stent placement by using a low-profile stent system (LEO Baby) for the treatment of challenging distal intracranial aneurysms.

Stent-Assisted Coiling of Wide-Neck Intracranial Aneurysms Using Low-Profile LEO Baby Stents: Initial and Midterm Results

“…Few articles have investigated the safety and efficacy of the treatment of intracranial aneurysms by using low-profile stents. 7,8,[12][13][14] The current study reports the retrospective experience of 3 university hospitals by using a low-profile stent system, the LEO Baby stent, for SAC treatment of wide-neck intracranial aneurysms.…”

“…Low-profile, self-expandable stents (LEO Baby and LVIS Jr), deliverable through microcatheters with an internal diameter of 0.0165 inches, were developed in 2011. 7,8,12 These low-profile stents allow easier catheterization and navigation in small-sized, delicate vessels and enable safer stent placement during the treatment of distal wide-neck aneurysms. Few articles have investigated the safety and efficacy of the treatment of intracranial aneurysms by using low-profile stents.…”

“…6 Low-profile self-expandable intracranial stents (LEO Baby; Balt, Montmorency, France; and LVIS Jr; MicroVention, Tustin, California) were introduced recently. 7,8 The designs of these stents enable their delivery into small arteries. These low-profile intracranial stents can be deployed into arteries with diameters as small as 1.5 mm to treat wide-neck aneurysms.…”

LEO Baby Stent Use following Balloon-Assisted Coiling: Single- and Dual-Stent Technique—Immediate and Midterm Results of 29 Consecutive Patients

“…Akmangit et al 18 recently reported a series of 12 patients treated with the LBS used in a dual-stent configuration for the treatment of wide-neck, complex, and distal intracranial aneurysms. Nine patients from this series were treated with dual-stent-assisted coiling with 2 LBSs deployed in Y-, X-, and T-configurations, while 3 patients were treated with 2 telescoped LBSs without adjunctive coiling.…”

Flow Diversion with Low-Profile Braided Stents for the Treatment of Very Small or Uncoilable Intracranial Aneurysms at or Distal to the Circle of Willis

“…Low-profile intracranial stents can be deployed into arteries with diameters between 1.5 and 3.5 mm, and they can be delivered through microcatheters with an internal diameter of 0.0165 inches, which allows easier navigation in small-sized, delicate vessels. 11 In this report, we present our experience with flow-diversion treatment as a stent monotherapy procedure for treating very small or uncoilable intracranial aneurysms located at or beyond the circle of Willis using low-profile braided stents. In this retrospective study, we investigated the feasibility, efficacy, and midterm durability of the stent monotherapy procedure with LEO Baby stents (Balt, Montmorency, France).…”
