Stent-assisted coil embolization of aneurysms with small parent vessels: safety and efficacy analysis

Abstract

Our results suggest that SACE of aneurysms with small parent vessels is feasible in selected cases and shows good long-term patency rates of parent arteries.

Safety and effectiveness of microsurgical clipping, endovascular coiling, and stent assisted coiling for unruptured anterior communicating artery aneurysms: a systematic analysis of observational studies

“…However, in their report, Fang et al did not differentiate the individual rates for EC and SAC, which makes direct comparison difficult. Although these reported rates of retreatment are low, and all instances of retreatment included in our study were performed without further procedural related complications,2 9 17 23 24 it should not be considered that the risks of retreatment are negligible, and the risk of retreatment should also be taken into account when deciding on a treatment strategy.…”

“…Six studies reported outcomes for unruptured aneurysms,5 9 14–17 and eight included a mix of patients with ruptured and unruptured cases 2 18–24. Twelve studies2 5 9 14 15 17–23 reported treatment outcomes exclusive to ACoA aneurysms, and two studies16 24 incorporated data on aneurysms at other locations. Documentation of the size among the treated aneurysms was highly heterogeneous among studies, and data on size was largely non-extractable.…”

“…Six studies reported outcomes using the GOS,14 16 17 19 23 24 two using the mRS,5 18 and six using qualitative descriptions 2 9 15 20–22. Coil embolization demonstrated high rates of good clinical outcome (EC 99.2%, MC 95.6%, SAC 92.1%; p=0.001), and corresponding low rates of poor clinical outcome (EC 0.8%, MC 4.4%, SAC 7.9%; p=0.001), in comparison with treatment with MC and SAC.…”

Preliminary Experience with Stent-Assisted Coiling of Aneurysms Arising from Small (<2.5 mm) Cerebral Vessels Using The Low-Profile Visualized Intraluminal Support Device

“…Several studies had detailed the use of different stents, including Neuroform (Stryker Neurovascular, Kalamazoo, Michigan), Wingspan (Stryker), LEO (Balt Extrusion, Montmorency, France), and Enterprise (Codman & Shurtleff, Raynham, Massachusetts) for the treatment of wide-neck intracranial aneurysms with small vessels. [4][5][6][7][8][9] According to the previous literature, thromboembolic events or vascular occlusions are major complications of stent-assisted coiling of these aneurysms ( at follow-up. Recently, 2 low-profile self-expandable microstents, LEO Baby and LVIS Jr, were introduced.…”

A Case of Ruptured Anterior Communicating Artery Aneurysm Treated in Which Residual Aneurysm after Coil Embolization Was Treated by Placement of LVIS Jr. Stent

“…In 44 cases treated by placement of Neuroform or Enterprise in parent arteries 2 mm or smaller in diameter, stenting was successful in 93.2%, but thromboembolism occurred in 13.6%. 8) Thus, thrombotic events tended to occur frequently after stenting of small-diameter parent arteries. Table 1 shows the recent literature concerning LVIS Jr. stent placement in peripheral vessels.…”
