“…Stent-assisted coiling remains a widely popular option for the treatment of aneurysm, according to a recent survey of 211 neurointerventionalists 4. The two types of intracranial stents used for the treatment of aneurysms with stent-assisted coiling are laser-cut and braided stents 5. Most of the literature describes operator experience with a single stent system.…”

IntroductionThe endovascular stent-assisted coiling approach for the treatment of cerebral aneurysms is evolving rapidly with the availability of new stent devices. It remains unknown how each type of stent affects the safety and efficacy of the stent-coiling procedure.MethodsThis study compared the outcomes of endovascular coiling of cerebral aneurysms using Neuroform (NEU), Enterprise (EP), and Low-profile Visualized Intraluminal Support (LVIS) stents. Patient characteristics, treatment details and angiographic results using the Raymond–Roy grade scale (RRGS), and procedural complications were analyzed in our study.ResultsOur study included 659 patients with 670 cerebral aneurysms treated with stent-assisted coiling (NEU, n=182; EP, n=158; LVIS, n=330) that were retrospectively collected from six academic centers. Patient characteristics included mean age 56.3±12.1 years old, female prevalence 73.9%, and aneurysm rupture on initial presentation of 18.8%. We found differences in complete occlusion on baseline imaging, defined as RRGS I, among the three stents: LVIS 64.4%, 210/326; NEU 56.2%, 95/169; EP 47.6%, 68/143; P=0.008. The difference of complete occlusion on 10.5 months (mean) and 8 months (median) angiographic follow-up remained significant: LVIS 84%, 251/299; NEU 78%, 117/150; EP 67%, 83/123; P=0.004. There were 7% (47/670) intra-procedural complications and 11.5% (73/632) post-procedural-related complications in our cohort. Furthermore, procedure-related complications were higher in the braided-stents vs laser-cut, P=0.002.ConclusionsThere was a great variability in techniques and choice of stent type for stent-assisted coiling among the participating centers. The type of stent was associated with immediate and long-term angiographic outcomes. Randomized prospective trials comparing the different types of stents are warranted.

“…28 The LEO Baby is a low-profile braided stent with high kink resistance, making it easy to deliver and deploy into acute-angled branches and curved vessels. 29 Although braided stents fit well with highly curved vessels and wide termini, their length can shorten in complex anatomy. To prevent this complication, a computational software-based simulation can be used to help select an appropriately sized stent.…”

Background The objective of this study was to present the long-term safety and effectiveness of strand remodelling with a hypercompliant balloon. Methods Patients with complex wide-neck bifurcation aneurysms (WNBAs) who underwent strand remodelling with a hypercompliant balloon via Y-stent-assisted coil embolization (Y-SACE) between September 2016 and January 2020 were included in the study. The feasibility, safety, effectiveness, and complication rates of the strand remodelling technique were investigated. Results A total of 12 patients (6 females, 6 males) were included in this study. Significant expansion was obtained in the intersection zone after remodelling. No regression was observed in the expansion rates during follow-up. There was no additional morbidity or mortality. No delayed thromboembolic complications occurred in our patients during long-term follow-up. Conclusions Performing strand remodelling to reduce thromboembolic complications triggered by structural faults caused by the Y-stent configuration is feasible, safe, and effective. This new approach can aid in the prevention of thromboembolic complications in Y-SACE.

“…At six-month follow-up, SAC offered a better outcome compared to BAC, with no statistical difference observed in retreatment rates and post-procedural complications [36] (Figure 4). There are two types of stents: laser-cut nitinol stents and braided stents [37]. The foremost category is further subclassified into closed-cell and open-cell design stents.…”

Traditionally, surgical clipping was the only available treatment modality for intracranial aneurysms. However, in the last few decades, the endovascular therapy of intracranial aneurysms (IAs) has seen a tremendous evolution and development. From coiling to flow diversion and flow disruptor devices, endovascular treatment modalities have increased in number and received broader indications throughout the years. In this review article, the treatment modalities for the endovascular management of IAs are presented, emphasizing newer devices and technologies.
