Abstract (sommario):

Background and purposeThe Medina embolization device (MED) is a new flow disruption device combining the design of a detachable coil with an intrasaccular flow disrupter. Safety and short-term angiographic effectiveness of this device have recently been reported. However, long-term angiographic results are lacking. We report herein the 18 months’ angiographic outcome in patients treated for a wide-neck intracranial aneurysm with the MED.Materials and methodsNineteen patients (17 female, mean age 50 years) with 20 wide-neck intracranial aneurysms (six ruptured; 14 unruptured) were treated by the MED between January 2015 and June 2016. Procedure-related complications were systematically recorded; discharge and 6–9 months' follow-up modified Rankin Scale scores were assessed. Angiographic mid-term and long-term follow-up were performed with a mean delay of 6.4±1.5 months (n=16 aneurysms) and 17.7±4.2 months (n=15 aneurysms), respectively. Occlusion rates were evaluated after the procedure and at the mid-term and long-term follow-up using the Roy-Raymond scale.ResultsEmbolization with the MED was feasible in all except two cases (2/20, 10%). One per-procedural perforation was recorded (1/20, 5%) and one MED deployment failed because of the aneurysm’s shape (1/20, 5%). Three cases of thromboembolic complications were observed (3/20, 15%). Only one thromboembolic complication was responsible for clinical sequelae. Grade A occlusion rate was 61% (11/18) after the procedure, 75% at 6 months' follow-up (12/16), and 80% (12/15) at long-term follow-up. Two cases (2/18, 11%) of recanalization at mid-term were documented angiographically. No recanalization occurred between the mid-term and long-term follow-up.ConclusionMED is a hybrid embolization device, combining properties of a conventional coil with those of an intrasaccular flow disrupter. Our series focusing on long-term angiographic follow-up shows a satisfactory long-term occlusion rate. Larger series with longer angiographic follow-up times are warranted to confirm these preliminary results.

Abstract (sommario):

Introduction The Woven EndoBridge (WEB) device is a novel intrasaccular flow disrupter designed for wide-necked aneurysms. We present our results of WEB treatment in previously treated and reopened aneurysms. Materials and methods Between February 2015 and December 2017, 17 patients with reopening of previously treated aneurysms were treated using the WEB device. Initial treatment was clipping in one, WEB in five and coiling in 11 aneurysms. Six aneurysms had two or three previous treatments. Mechanism of aneurysm reopening was clip remnant in one, compaction without regrowth in three, focal regrowth in five, reopening in partially thrombosed aneurysms in three and WEB compression in five aneurysms. Results Endovascular treatment of the recurrent aneurysm was possible in all 17 patients with good WEB position obtained. Additional devices were used in three of 17 patients (18%): coils in two and stent in one patient. No technical, hemorrhagic or thromboembolic complications occurred (0%, 97.5% confidence interval 0–22%). Overall imaging result at latest follow-up was complete occlusion in five (29%), neck remnant in six (35%), aneurysm reopening in six (35%) and persistent WEB filling in one aneurysm (6%). After retreatment with the WEB, two aneurysms were again additionally treated and three aneurysms are scheduled for additional treatment. Worst results were in partially thrombosed aneurysms. Conclusion The WEB device for recurrent aneurysms may be a feasible and safe option, especially in wide-necked, shallow aneurysm recurrences. Results were poor in partially thrombosed recurrent aneurysms.

Abstract (sommario):

Background: The endovascular treatment of complex intracranial aneurysms, such as wide-neck aneurysms (WNAs), remains a challenge. More established endovascular techniques, which include balloon-assisted coiling, stent-assisted coiling, and flow diversion, all have their drawbacks. Intrasaccular flow disruptor devices have emerged as a useful tool for the neurointerventionalist. Methods: Here, we discuss landmark studies and provide a comprehensive, narrative review of the Woven EndoBridge (WEB; Microvention, Alisa Viejo, CA, USA), Artisse (Medtronic, Irvine, CA, USA), Contour (Stryker, Kalamazoo, MI, USA), Saccular Endovascular Aneurysm Lattice Embolization System (SEAL; Galaxy Therapeutics Inc, Milpitas, CA, USA), Medina (Medtronic, Irvine, CA, USA), and Trenza (Stryker, Kalamazoo, MI, USA) devices. Results: Intrasaccular devices have proven to be effective in treating complex aneurysms like WNAs. Conclusions: Intrasaccular flow disruptors have emerged as a new class of effective endovascular therapy, and results of ongoing clinical studies for the newer devices (e.g., SEAL and Trenza) are much anticipated.

Abstract (sommario):

Background: Intrasaccular flow disruptors (IFD) have been introduced in the treatment of intracranial aneurysms (IAs) to overcome the low aneurysm occlusion rate and the high recanalization rate of the coiling technique. Among them, the Contour Neurovascular System (CNS) and the Neqstent (NQS) were designed to reconstruct the aneurysmal neck and both can be used as assisting coiling devices. We aimed to report our preliminary experience with the flow disruptor-assisted coiling (IFD-AC) technique. Methods: We performed a retrospective analysis of prospectively collected data of all patients with IAs treated with the IFD-AC. Results: Between February 2021 and April 2022, we treated 15 IAs with the IFD-AC: 10 ruptured and 5 unruptured. The IFD-AC was successfully performed in 13 cases, with a post-operative RROC 1 in 12 cases (92.3%) and RROC 2 in 1 case (7.7%). There was one ischemic event (6.7%) and no hemorrhagic complications. Twelve patients underwent a mid-term radiologic follow-up: Ten IAs (83.4%) presented an adequate occlusion, while 2 (16.7%) had a recurrence. Conclusions: The IFD-AC, both with the CNS and the NQS, seems a safe technique with promising efficacy profile. The IFD-AC has proved to be safe without antiplatelet therapy in ruptured cases. Further studies are needed to confirm our preliminary results.

Abstract (sommario):

Purpose: Advances in endovascular technology have expanded the treatment options for intracranial aneurysms. Intrasaccular flow diversion is a relatively new technique that aims to disrupt blood inflow at the neck of the aneurysm, hence promoting intrasaccular thrombosis. The Woven EndoBridge device (WEB; MicroVention, Aliso Viejo, CA, USA) is an US Food and Drug Administration approved intrasaccular flow diverter for wide-necked aneurysms. We report the early interim clinical and radiological outcomes of patients with both ruptured and unruptured intracranial aneurysms (IAs) treated using the WEB device in an Australian population.Materials and Methods: A retrospective analysis was done of patients with ruptured or unruptured IAs who received treatment with WEB across 5 Australian neuroendovascular referral centers between May 2017 and November 2020. Angiographic occlusion was assessed with time-of-flight magnetic resonance angiography. Complications were recorded and clinical outcomes were assessed using the modified Rankin scale at follow-up.Results: In total, 66 aneurysms were treated in 63 patients, with successful deployment of the WEB device in 98.5% (n=65). Eighteen (26.9%) ruptured aneurysms were included. Failure of deployment occurred in a single case. Adjunct coiling and/or stenting was performed in 20.9% (n=14) cases. Sixty-two patients with 65 aneurysms using a WEB device were followed up (mean=9.1 months), and 89.4% of these had complete aneurysm occlusion while 1.5% remained patent. Functional independence was achieved in 93.5% of cases.Conclusion: Early results following the use of WEB devices in Australia demonstrate safety and adequate aneurysm occlusion comparable to international literature.

Abstract (sommario):

La prise en charge diagnostique et thérapeutique des accidents vasculaires cérébraux a radicalement changé ces dernières décennies. Des stratégies de traitement des infarctus cérébraux par recanalisation intraveineuse de l’artère ont été évaluées dans les années 1990. Lorsque l’occlusion artérielle touche un gros vaisseau, les techniques de neuro-interventions endovasculaires récentes ont montré une grande efficacité de la thrombectomie mécanique. Les interventions endovasculaires permettent également depuis de nombreuses années de participer à la prise en charge des AVC de type hémorragie sous-arachnoïdienne anévrismale. Historiquement exclusivement traités par neurochirurgie ouverte, les techniques endovasculaires utilisant les coils détachables se sont rapidement démocratisées dans cette indication, en parallèle d’un développement technique très important. De nombreux nouveaux dispositifs médicaux ont notamment été mis sur le marché pour combler les difficultés liées à certaines anatomies : ballons de remodelling, stents intracrânien. Plus récemment les stents à diversion de flux et les dispositifs intra-saculaires se sont positionnés comme des évolutions technologiques des procédures précédentes. Ces dispositifs sont aujourd’hui largement utilisés pour le traitement d’anévrismes rompus en urgence ou programmés suite à la découverte fortuite de lésions jugées à risque. L’impression 3D est une évolution technologique qui pourrait permettre de sécuriser certains traitements endovasculaires. Les modalités d’imageries déjà existantes permettent de réaliser des modèles 3D spécifiques au patient, permettant aux opérateurs de s’entraîner avec différents dispositifs afin de planifier au mieux la future procédure. Enfin il semble nécessaire d’évaluer les techniques de reperfusion cérébrale au sein des réseaux régionaux de télé-AVC et l’apport des nouvelles technologies de robotique dans ce domaine. L’assistance robotique leader-follower est un outil pouvant améliorer le confort de l’opérateur et son exposition aux rayonnements ionisants. Le contrôle robotique des cathéters pourrait améliorer la précision des procédures et à termes à la sécurité des patients. Enfin le système pourrait permettre un fonctionnement distant ouvrant la voie à des télé-procédures contrôlées à distance par l’opérateur expert, assisté de techniciens spécialisés sur site. L’implémentation de cette technologie, en particulier concernant l’ischémie aiguë, pourrait drastiquement diminuer les délais de recanalisation et ainsi améliorer le pronostic fonctionnel des patients. Nous proposons ici d’aborder la problématique d’évaluation de ces dispositifs en nous concentrant sur 3 développements technologiques récents : les dispositifs intracrâniens de traitement des anévrismes innovants (stents flow diverters et intrasaculaires), l’impression 3D pré-opératoire et la robotique endovasculaire
The diagnostic and therapeutic management of stroke has changed radically in recent decades. Strategies for treating cerebral infarctions by intravenous recanalization of the artery were evaluated in the 1990s. In case of large vessel occlusion, recent neurointerventional techniques demonstrated great efficacy with mechanical thrombectomy. For many years, endovascular interventions have also made it possible to participate in the management of strokes such as aneurysmal subarachnoid hemorrhage. Historically treated exclusively by open neurosurgery, endovascular techniques using detachable coils have quickly exanded in this indication, in parallel with significant technical development. Many new medical devices have entered the market in particular to overcome challenging anatomies: remodeling balloons, intracranial stents. More recently, flow diversion stents and intra-saccular devices have positioned themselves as technological developments of previous procedures. These devices are now widely used for the treatment of acute ruptured aneurysms or elective treatments following the incidental discovery of risky lesions. 3D printing is a technological development that could make certain endovascular treatments safer. Digital subtracted angiographies make it possible to create patient-specific 3D models, allowing operators to train with different devices in order to better plan the future procedure. Finally, it seems necessary to evaluate cerebral reperfusion techniques within regional telestroke networks and the contribution of new robotic technologies in this field. Leader-follower robotic assistance is a tool that can improve operator comfort and exposure to ionizing radiation. Moreover, robotic control of catheters could improve the precision of procedures and ultimately patient safety. Finally, the system could allow remote operations, paving the way for teleprocedures controlled remotely by the expert operator, assisted by specialized technicians on site. The implementation of this technology, particularly concerning acute ischemia, could drastically reduce recanalization times and thus improve the functional prognosis of patients. Here we propose to address the problem of evaluating these devices by focusing on three recent technological developments: innovative intracranial devices for treating aneurysms (flow diverters and intrasacular stents), preoperative 3D printing and endovascular robotics
