OBJECTIVECoiling of wide-necked and complex bifurcation aneurysms frequently requires implantation of double stents in various configurations. T-stent–assisted coiling involves the nonoverlapping implantation of 2 stents to protect the daughter vessels of bifurcation and is followed by coiling of the aneurysm. The authors studied the feasibility, efficacy, and safety of the T-stent–assisted coiling procedure as well as the midterm angiographic/clinical outcomes of patients with wide-necked bifurcation intracranial aneurysms treated using this technique.METHODSThe authors retrospectively identified patients with wide-necked bifurcation intracranial aneurysms treated using double-stent–assisted coiling with a T-stent configuration.RESULTSTwenty-four patients with 24 aneurysms and a mean of age of 51.91 years were identified. The most common locations were the middle cerebral bifurcation (45.8%) and anterior communicating artery (35.7%). T stentings were performed using low-profile stents. The procedures were performed with a technical success rate of 95.8%, and an immediate total occlusion rate of 79.2% was achieved. We observed periprocedural complications in 16.7% of cases and a delayed thromboembolic event in 4.2%. The complications caused permanent morbidity in 1 patient (4.2%). No deaths occurred. The mean angiographic follow-up duration was 9.3 months. The total occlusion rate at the last follow-up was 81.2%. The recanalization rate was 4.5%. Modified Rankin Scale scores of all patients at the last follow-ups were between zero and 2.CONCLUSIONST-stent–assisted coiling using low-profile stents is a feasible, effective, and relatively safe endovascular technique used to treat wide-necked and complex intracranial aneurysms. The midterm angiographic and clinical outcomes are outstanding.

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 BACKGROUND The Medina Embolization Device (MED) is a new concept device that combines the design of a detachable coil and the one of an intrasaccular flow disruption device. OBJECTIVE To evaluate the feasibility, safety, and 6- to 9-mo effectiveness of this new device for the treatment of intracranial wide-necked aneurysms. METHODS Twelve patients (10 females, mean age = 56 yr) with 13 wide-necked intracranial aneurysms (3 ruptured; 10 unruptured) were treated by means of the MED from January 2015 to October 2015. In 15% of the cases, MEDs were used in a standalone fashion; in 85% of the cases, additional regular coils were used. Adjunctive compliant balloon was used in 4 of 13 cases (31%). Procedure-related complications were systematically recorded; discharge and 6- to 9-mo follow-up modified Rankin Scale was assessed. Angiographic follow-up was performed with a mean delay of 5.5 ± 1.7 mo. Occlusion rate was evaluated in postprocedure and at midterm follow-up using the Roy–Raymond scale. RESULTS The deployment of the MED was feasible in all cases. No perforation was recorded. One case of thromboembolic complication was observed in a ruptured anterior communicating artery aneurysm, without any clinical consequence at follow-up. Grade A occlusion rate was 61.5% in postprocedure and 83% at 6-mo follow-up. Two cases (17%) of recanalization were documented angiographically. CONCLUSION The MED is a new generation device combining the design of a detachable coil and an intrasaccular flow disruption device. According to our early experience, this device is safe and provides a satisfactory occlusion rate at angiographic follow-up of 6 mo.

Objective: To evaluate the safety and efficacy of low-profile visualized intraluminal support (LVIS) stent-assisted coiling for the treatment of ruptured wide-necked anterior communicating artery (ACoA) aneurysms.Methods: The clinical and angiographic data of 31 acutely ruptured wide-necked ACoA aneurysms treated with LVIS stent-assisted coiling between January 2014 and December 2018 were retrospectively reviewed.Results: All stents were successfully deployed. The immediate angiographic results were modified Raymond-Roy class I in 27 cases, modified Raymond-Roy class II in 2 cases, and modified Raymond-Roy class IIIa in 2 cases. Intraoperative thrombosis and postoperative aneurysmal rebleeding occurred in one case each. Two patients (6.5%) who were admitted due to poor clinical grade conditions died during hospital admission as a result of initial bleeding. Angiographic follow-up (mean: 12.9 months) was performed for 26 patients, the results of which demonstrated that 25 aneurysms were completely occluded and one was class II. The last clinical follow-up (mean: 25.3 months) outcomes demonstrated that 27 patients had favorable clinical outcomes and two had poor clinical outcomes.Conclusion: LVIS stent-assisted coiling for ruptured wide-necked ACoA aneurysms was safe and effective, with a relatively low rate of perioperative complications and a high rate of complete occlusion at follow-up.

Background: Over the years, a variety of intracranial stents have been developed, which has expanded the therapy options available for cerebral aneurysms. The Low profile visible intraluminal support (LVIS) EVO stents are new devices, which officially appeared on the market in 2020. The purpose of the study is to report the initial technical and clinical experience with the new stent in the treatment of intracranial aneurysms. Materials and Methods: Between February and September 2020, 30 patients with 35 intracranial aneurysms (29 unruptured and 6 ruptured) were treated using the LVIS EVO stent in our department. The aneurysms were located within internal carotid artery (ICA) (42.9%), middle cerebral artery (MCA) (31.4%), anterior communicating artery (AComA) (11.4%), basilar artery (BA) (11.4%) and anterior cerebral artery (ACA) (2.9%). Stent-assisted coil embolization was performed in all cases. Results: All stents were deployed successfully in the desired position. Immediate complete occlusion of the treated aneurysms, described as Raymond–Roy occlusion classification (RROC) class 1, was achieved in all cases. No technical complications were observed. One thromboembolic complication occurred in the group of unruptured aneurysms and one patient died due to cerebral edema from aneurysms rupture group. Conclusion: In our observation, the showed a satisfactory safety profile LVIS EVO stents seem to be very flexible, can be safely maneuvered and deployed in tortuous vessels. They showed a good initial occlusion rate when used for treating intracranial aneurysms with SAC (stent-assisted coiling).

PurposeSelf-expandable stents have broadened the spectrum of endovascular treatment of intracranial aneurysms. However, procedures involving double stenting in Y/X configurations carry a relatively high risk of procedural complications. The Neuroform ATLAS, the evolution of Neuroform EZ, is a nitinol self-expanding hybrid/open cell stent which can be delivered through a low profile 0.017 inch catheter. We present our experience in the treatment of intracranial aneurysms with this stent in Y and X configurations.Materials and methodsWe prospectively maintained a database from consecutive patients who underwent double stent assisted coiling with the Neuroform ATLAS, from July 2015 to February 2019. Clinical and angiographic results were analyzed.Results55 patients harboring 55 bifurcation aneurysms were treated with double stenting: 52 ‘Y’ configurations, 3 ‘X’ configurations. Deployment was successful in all cases. Post-treatment control angiography showed complete occlusion in 33 cases (60%), neck remnant in 8 cases (14.5%), and incomplete occlusion in 14 cases (25.4%). The overall symptomatic periprocedural complication rate was 12.7%. 38 aneurysms underwent follow-up (69%, mean duration 16 months): 33 aneurysms (87%) were completely occluded, 3 aneurysms (8%) had a neck remnant, and 2 aneurysms (5%) were incompletely occluded.ConclusionThe Neuroform ATLAS is an effective device for treatment of bifurcation aneurysms, allowing good conformability, a high level of navigability, and easy mesh crossing to perform Y/X stenting procedures. The rate of procedural complications remains non-negligible, and an indication for a double stenting procedure should be carefully discussed in a multidisciplinary meeting.

Background and purpose This retrospective study evaluates the safety, effectiveness, and long-term clinical and angiographic follow-up of intracranial aneurysms treated with the Low-Profile Visualized Intraluminal Support Junior (LVIS Jr.) stent and parent vessels of diameter equal to or less than 2.5 mm. Materials and methods We included all patients treated with the LVIS Jr. stent in aneurysms with small parent vessel diameter between March 2015 and July 2017. Periprocedural adverse events, immediate aneurysm occlusion rates, and clinical and angiographic follow-up are reported. Results A total of 35 patients with 35 aneurysms were included. Ten aneurysms were ruptured (28.6%) and 25 were unruptured (71.4%). The parent arteries measured 0.9 mm to 2.5 mm in diameter (mean, 2.2 mm). Intra-procedural thromboembolic complications occurred in four patients (11.4%) and there was an intraoperative aneurysm rupture in one patient (2.8%). Immediate complete aneurysm occlusion was noted in 21 out of 35 patients (60%). Clinical follow-up ranged between one and 25 months (mean, 10.5 months) and magnetic resonance angiography follow-up ranged between four and 24 months (mean, 10.4 months). Complete aneurysm occlusion was achieved in 21 out of 29 patients (72.4%) at last angiographic follow-up (mean, 9.4 months; range four to 23 months). In-stent stenosis occurred in one out of 29 patients (3.4%), who was asymptomatic. Of the four patients with in-stent thrombosis, three patients were treated with “Y configuration” (two patients with middle cerebral artery aneurysms and one patient with an anterior communicating artery aneurysm). Mortality rate was 0%. Neurological morbidity was 2.9%. Conclusions Stenting with the LVIS Jr. stent allowed us to treat complex intracranial aneurysms with parent vessel diameter of 2.5 mm or less with an acceptable safety profile.

Purpose: Standard coiling is now the first line approach for the treatment of intracranial aneurysms. However, this technique has some limitations, including treatment of wide-neck and large and giant aneurysms and recanalizations. Therefore, new techniques and devices are needed. The objective of intra-saccular flow disruption is the modification of aneurysmal flow by placing a device in the aneurysm sac. Clinical experience with this new technique is analyzed in a series collected in 11 French centers. Materials and Methods: The WEB (Sequent, Aliso Viejo, CA) is a self-expanding, oblate, braided nitinol mesh, composed of an inner and outer braid held together by proximal, middle, and distal radio-opaque markers and creating two compartments: one distal and one proximal. 66 patients (49F/17M, age: 36-75 years) harbouring 68 aneurysms (ruptured: 5, unruptured: 57 or recanalized: 6) were treated between June 2011 and July 2013. Aneurysm location was middle cerebral artery (39 aneurysms), basilar artery (16), anterior communicating artery (7), and internal carotid artery (6). Results: The device was successfully deployed in all but 4 cases (failure rate: 5.9%). Additional coiling was performed in 6 aneurysms, remodeling in 2 cases, and stenting in 1 case. One intraoperative rupture was observed in a ruptured aneurysm (1.5%). Six thromboembolic events (8.8%) were observed with transient clinical worsening and good clinical outcome in 5 cases (mRS ≤2). No delayed rupture or remote hematoma was observed. Finally mortality was 0.0% and morbidity 1.5% (in a patient who both had intraoperative rupture and thromboembolic complication). Anatomical follow-up was obtained in 32 patients 3 to 15 months after the treatment. Total occlusion was obtained in 15/32 aneurysms (46.9%), neck remnant in 14/32 aneurysms (43.8%), and aneurysm remnant in 3/32 aneurysms (9.4%). Conclusion: In the present series reporting the initial clinical experience with intra-saccular flow disruption using WEB in 11 French centers, the feasibility of treatment is high, the safety profile similar to coiling, and anatomical results are quite satisfactory knowing that some neck remnants are in fact just opacification of the proximal recess of the device.

Introduction: The Low-Profile Visualized Intraluminal Support (LVIS) devices are a new generation of self-expandable, high-porosity stents approved for the treatment of large to giant wide-necked intracranial aneurysms via stent-assisted coiling. Here we report the radiographic and clinical outcomes seen with LVIS, LVIS Jr. and LVIS Blue from a single institution over a five-year period. Methods: Patients with intracranial aneurysms treated by LVIS, LVIS Jr. and LVIS Blue technology over a five-year period (2012 - 2017) at our institution were retrospectively reviewed. Results: Seventy-four patients (55 females and 19 males; average age = 59.2) with 74 aneurysms underwent embolization of intracranial aneurysms using LVIS (N =10), LVIS Jr. (N = 47) or LVIS Blue (N =12) devices at our institution over the study period. The most common location of treated aneurysms was the anterior communicating artery (31%), followed by the basilar artery (19%), and the middle cerebral artery (13%). The mean neck and dome sizes were 3.9±1.5mm and 6.6±3.2mm, respectively. The median follow-up time was 6 months. At the last radiographic follow-up, 93.1% of patients had complete occlusion (RR-I or OKM-D). In 5 cases (7%), the LVIS stent failed to open, requiring balloon angioplasty (N=3) or stent recapture and use of a non-LVIS branded device (N=2). Five patients had post-embolization infarcts, and 1 patient had an intra-operative dome rupture. Conclusion: LVIS brand of stents is a safe, effective, and technically feasible treatment strategy for wide-neck intracranial aneurysms, with high deployment success and aneurysm obliteration rates.

Abstract BACKGROUND: Ruptured anterior communicating artery (ACoA) aneurysms are heterogeneous intracranial aneurysms whose diverse morphological features influence treatment modality. OBJECTIVE: To compare clinical outcomes and complications of all ruptured ACoA aneurysms treated by clipping or coiling in a modern institutional trial. METHODS: All patients with ruptured ACoA aneurysms in the Barrow Ruptured Aneurysm Trial were included. Clinical follow-up at 1 and 3 years was analyzed; charts were reviewed for patient demographics, aneurysm characteristics, and in-hospital complications. RESULTS: This cohort included 130 patients (mean age, 52.5 years). Mean aneurysm size was 5.8 mm. Most aneurysm domes projected anteriorly (n = 52). After randomization and crossover, 91 ACoA aneurysms (70%) were clipped and 39 (30%) were coiled. Twenty-two patients (16.9%) initially randomized to coiling crossed over to clipping after evaluation. No patients crossed over from clipping to coiling. Characteristics precluding aneurysms from coiling included unfavorable dome-to-neck ratio, lesions difficult to access by catheter, and branch vessel involvement. Aneurysm size and dome projection were not significantly associated with treatment group, clinical outcome, or retreatment. No significant difference existed in clinical outcome (modified Rankin Scale scores) between groups at discharge or at 1-year or 3-year follow-up using as-treated and intention-to-treat analyses. Retreatment was performed in 3 clipped patients (2.3%) and 3 coiled patients (2.3%). CONCLUSION: Ruptured ACoA aneurysms, regardless of size and projection, were safely treated by both treatment modalities in a large-scale randomized clinical trial. Clinical outcomes and stroke rates did not differ significantly in as-treated or intention-to-treat analyses.

BackgroundThe use of robotics in medicine may enable increased technical accuracy, reduced procedural time and radiation exposure, and remote completion of procedures. We have previously described the first-in-human, robotic-assisted cerebral aneurysm treatment using the CorPath GRX Robotic System. In this report we discuss our early experiences and outcomes using this robotic device for endovascular treatment of intracranial aneurysms using stent-assisted coil embolization and flow diversion.MethodsThe patient and disease characteristics, procedural details, and follow-up imaging and clinical outcomes of consecutive patients undergoing robotically-assisted intracranial aneurysm embolization between November 2019 and February 2020 are presented.ResultsSix patients underwent robotically-assisted embolization of intracranial aneurysms. Four of the patients were treated with a neck-bridging stent (with or without coiling) and two patients were treated with a flow-diverting stent. Two patients were treated in the subacute period of subarachnoid hemorrhage and four patients were treated electively. All of the procedures could be completed robotically and there was no need for unplanned manual intervention. The technical success rate of the procedures was 100%. There was no morbidity or mortality associated with the procedures. One year follow-up imaging showed that four aneurysms were completely obliterated (Raymond-Roy Occlusion Classification (RROC) class I) and the remaining two were occluded with a residual neck (RROC class II).ConclusionsThe Corpath GRX Robotic System demonstrated a precise control over the microcatheter, wire and stent during aneurysm treatment. Robotic neuro-procedures seem to be safe and effective and demonstrate stable occlusion results in the midterm follow-up.
