Abstract
BACKGROUND Despite the widespread use of the Wingspan stent system for treating severe medically refractory intracranial artery stenosis (SMR-ICAS), a new Credo stent system was approved because it could integrate stent delivery within the balloon catheter. However, the therapeutic outcomes of these two systems have not been compared. This preliminary study aimed to compare the results of percutaneous angioplasty and stenting (PTAS) in SMR-ICAS patients treated with either Wingspan or Credo stents within the anterior cerebral circulation. METHODS SMR-ICAS patients with >70% stenosis in the anterior circulation who underwent PTAS using either the Wingspan or Credo stent system were retrospectively analyzed. We evaluated the technical success, safety, and outcomes of the two-stent systems. RESULTS A total of 29 patients were analyzed, including 17 patients treated with Wingspan stents and 12 with Credo stents. The outcomes of the Wingspan stent vs Credo stent were as follows: technical success (16/17 [94%] vs 11/12 [92%], p = 1.00); periprocedural intracranial hemorrhage (2/17 [12%] vs 0/12 [0%], p = 0.50); silent embolic ischemic lesions on periprocedural magnetic resonance imaging (MRI) (13/17 [76%] vs 7/12 [58%], p = 0.42); and significant (>50%) in-stent restenosis in 1 year (4/17 [24%] vs 2/12 [17%], p = 1.00). No recurrent stroke or mortality was noted within 30 days after the procedures or during the 1-year follow-up period. CONCLUSION The technical success, safety, and outcomes of the Credo stent system were comparable to those of the Wingspan stent system in the management of SMR-ICAS patients. Further large-scale studies are warranted to substantiate these findings.

Abstract
BACKGROUND Intracranial arterial stenting is a technique for the treatment of symptomatic stenosis. In this single-center retrospective case series we evaluated a novel low profile laser-cut stent with an antithrombogenic hydrophilic polymer coating (pEGASUS-HPC, Phenox GmbH, Bochum, Germany) for the treatment of intracranial stenosis in the setting of acute ischemic stroke and elective cases. METHODS All patients treated with pEGASUS-HPC for one or more intracranial arterial stenoses at our institution were retrospectively included. Clinical, imaging and procedural parameters as well as clinical and imaging follow-up data were collected. RESULTS We performed 43 interventions in 41 patients with 42 stenoses in our neurovascular center between August 2021 and February 2024. Twenty-one patients (51.2%) were female and the mean±SD age was 71±10.8 years. Thirty-seven (86.1%) procedures were performed in the setting of endovascular acute ischemic stroke treatment. Technical or procedural complications occurred in seven patients (16.3%), six in the thrombectomy group and one in the elective group. One stent-related hemorrhagic complication (subarachnoid hemorrhage) occurred in emergency cases and symptomatic intracerebral hemorrhage occurred in one patient treated in an elective setting. Overall stenosis reduction following pEGASUS-HPC stent implantation was 53.0±18.0%. On follow-up imaging, which was available for 16 patients (37.2%) after an average of 32±58.6 days, 62.5% of the stents were patent. CONCLUSION Our single-center case series demonstrates the feasibility of using the pEGASUS-HPC stent system, especially in emergency situations when thrombectomy fails.

Abstract
BACKGROUND Angioplasty and/or stenting is a rescue therapy for mechanical thrombectomy (MT) in acute intracranial large vessel occlusion. This study was undertaken to determine whether rescue angioplasty and/or stenting improves the outcome after MT and to investigate whether outcomes differ by subgroup of rescue indication. METHODS We performed propensity score matching (PSM) with data from a prospective multicenter registry of patients with acute large vessel occlusion receiving endovascular treatment. Patients were divided into the MT alone group and the MT with rescue therapy group. The primary outcome was functional independence (modified Rankin Scale score of 0-2) at 90 days. PSM was also performed in the failed MT (modified Thrombolysis In Cerebral Infarction (mTICI) 0-2a) and the residual severe stenosis (mTICI 2b-3) subgroups, respectively. RESULTS 326 patients of mean±SD age 62.7±12.0 years (90 women, 27.6%) were matched from 1274 patients. In the matched cohort, functional independence at 90 days was higher in the rescue therapy group than in the MT alone group (44.2% vs 29.5%; OR 1.90, 95% CI 1.18 to 3.06, P=0.008). In the failed MT subgroup with 66 matched pairs, more patients had functional independence in the rescue therapy group than in the MT alone group (39.0% vs 17.0%; OR 3.12, 95% CI 1.29 to 7.59, P=0.01). In the residual stenosis subgroup with 63 matched pairs, functional independence rates were similar in the rescue therapy and the MT alone groups (51.6% vs 55.7%; OR 0.85, 95% CI 0.42 to 1.72, P=0.65). CONCLUSION Rescue angioplasty and/or stenting could improve the clinical outcome in patients with acute large vessel occlusion with failed MT, while no benefit was seen in those with residual severe stenosis but substantial reperfusion.

Evaluation of effectiveness and safety of the large-format pRESET 6-50 thrombectomy stent-retriever in the endovascular treatment of ischemic stroke: real-world experiences from two tertiary comprehensive stroke centers. Front Neurol 2023; 14:1256365. [PMID: 38046595 PMCID: PMC10690812 DOI: 10.3389/fneur.2023.1256365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 10/19/2023] [Indexed: 12/05/2023] Open
Abstract
Objective Mechanical thrombectomy (MT) has become the standard treatment for acute ischemic stroke (AIS) with large vessel occlusion (LVO). First-pass (FP) reperfusion of the occluded vessel and fewer passes with stent retrievers show improvement in functional outcomes in stroke patients, while higher numbers of passes are associated with higher complication rates and worse outcomes. Studies indicate that a larger size of the stent-retriever is associated with a higher rate of first-pass reperfusion and improved clinical outcomes. In this retrospective study, we investigated the clinical performance of a recently developed and one of the largest stent-retrievers available in the treatment of LVO (pRESET 6-50, phenox GmbH, Bochum). Materials and methods All consecutive patients with ischemic stroke due to proximal large vessel occlusion treated with MT using the pRESET 6-50 stent-retriever in two tertiary stroke centers between 09/2021 and 07/2022 were included in this study. The reperfusion rate after MT was quantified by the modified thrombolysis in cerebral infarction (mTICI) score, and functional neurological outcome was evaluated with the National Institutes of Health Stroke Scale (NIHSS) score and the major early neurological recovery (mENR) rate after 24 h. Successful FP reperfusion was defined as mTICI ≥ 2b. Successful and complete reperfusion were defined as mTICI ≥ 2b and mTICI ≥ 2c, respectively. Results In total, 98 patients (52 men and 46 women) with a median age of 75 (range 25-95 years) were included. A total of 70 (72%) patients presented with an occlusion of the middle cerebral artery (MCA) in the M1 segment, 6 (6%) patients with an occlusion of the M2 segment, 17 (17%) patients with an occlusion of the internal carotid artery (ICA), and 5 (5%) patients with an occlusion of the obstructed basilar artery (BA). Successful FP reperfusion was achieved in 58 patients (62%). Successful and complete reperfusion were achieved in 95 (97%) and 82 (83%) patients, respectively. The median National Institutes of Health Stroke Scale (NIHSS) in all treated patients improved from 17 to 7.5. Major early neurological recovery (mENR) was observed in 34 patients (35.1%). Conclusion MT with the pRESET 6-50 stent-retriever achieves high successful first-pass and final reperfusion rates in patients with AIS and LVO. The results of this study support the thesis to use large-format stent-retriever in proximal vessel occlusion MT whenever feasible in order to improve high FP and final reperfusion rate, which are known predictors of good clinical outcome.

Neurosurg Rev 2023; 46:234.

Abstract
Dual-lumen angioplasty balloon microcatheters make it possible to perform percutaneous transluminal angioplasty (PTA), low-profile stent delivery, and intrastent dilation without the microcatheter exchange technique. This technique has shown many advantages in recent years. We reviewed the techniques and applications in different intracranial vascular diseases and summarized the outcomes and indications. Gateway dual-lumen angioplasty balloon was used for PTA and kept in situ. Stent was delivered and deployed via Gateway microcatheter. Intrastent balloon dilation was performed after stent deployment. We retrospectively reviewed the clinical and imaging data, surgical procedures, technique application, and follow-up outcomes of six patients treated from 2020 to 2023. Neurological function was assessed by the modified Rankin scale (mRS). A literature review was performed using PubMed. All seven patients (4 males, 3 females; mean age, 62.6 ± 6.9 years) underwent percutaneous transluminal angioplasty and stent deployment using a balloon microcatheter. There was one middle cerebral artery (MCA) aneurysm with parent artery stenosis, two MCA dissections, and four intracranial atherosclerotic stenoses (ICASs). The mRS score was 0 in five patients and 1 in two patients. Cerebral dissection with stenosis is the best indication, and its application in stent-assisted aneurysm coiling is inappropriate. This technique is controversial in ICAS treatment.

Abstract
BACKGROUND Intracranial atherosclerotic disease (ICAD) is a common cause for stroke and can be defined as symptomatic (stroke) or asymptomatic. Current guidelines recommend against intracranial stenting (ICS) for patients with ICAD; treatment of patients who failed the best medical therapy is still debatable. METHODS We introduce a preliminary retrospective analysis of our tertiary stroke center during 2018-2022 of patients that were treated with ICS either in acute phase or elective (eICS). Study endpoints were stroke, functional outcome (modified Rankin Score [mRS] at 3 months), and serious adverse events. RESULTS Thirty-three stents were implanted, 21 in acute group and 12 in the eICS group. Most patients (75%) were treated with a new generation self-expandible stent. One patient had peri-procedural stroke and four patients had transient ischemic event or stroke during follow-up. There were eight cases of death (all acute group patients, seven of which occurred in the posterior circulation). Fifteen patients (62%) had favorable clinical outcomes (mRS 0-2 for pre-stroke), of which 10/10 (100%) in the eICS, the other two eICS patients had pre-morbid mRS 3 with no clinical change. CONCLUSIONS The evolution of new devices for ICS and the accumulating interventional experience might open a new era. As no other effective alternative treatment options exist for preventing recurrent stroke, stenting is still common practice in many tertiary centers either urgently or as elective procedure for refractory cases.

Rescue therapy after thrombectomy for large vessel occlusion due to underlying atherosclerosis: review of literature. Front Neurol 2023; 14:1181295.

Abstract
In this review article, we summarized the current advances in rescue management for reperfusion therapy of acute ischemic stroke from large vessel occlusion due to underlying intracranial atherosclerotic stenosis (ICAS). It is estimated that 24-47% of patients with acute vertebrobasilar artery occlusion have underlying ICAS and superimposed in situ thrombosis. These patients have been found to have longer procedure times, lower recanalization rates, higher rates of reocclusion and lower rates of favorable outcomes than patients with embolic occlusion. Here, we discuss the most recent literature regarding the use of glycoprotein IIb/IIIa inhibitors, angioplasty alone, or angioplasty with stenting for rescue therapy in the setting of failed recanalization or instant/imminent reocclusion during thrombectomy. We also present a case of rescue therapy post intravenous tPA and thrombectomy with intra-arterial tirofiban and balloon angioplasty followed by oral dual antiplatelet therapy in a patient with dominant vertebral artery occlusion due to ICAS. Based on the available literature data, we conclude that glycoprotein IIb/IIIa is a reasonably safe and effective rescue therapy for patients who have had a failed thrombectomy or have residual severe intracranial stenosis. Balloon angioplasty and/or stenting may be helpful as a rescue treatment for patients who have had a failed thrombectomy or are at risk of reocclusion. The effectiveness of immediate stenting for residual stenosis after successful thrombectomy is still uncertain. Rescue therapy does not appear to increase the risk of sICH. Randomized controlled trials are warranted to prove the efficacy of rescue therapy.

Angioplasty, stenting, or both - rescue maneuvers and reperfusion after endovascular therapy for intracranial atherosclerosis-related occlusion. Neuroradiology 2023; 65:775-784. [PMID: 36609714 DOI: 10.1007/s00234-022-03108-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 12/18/2022] [Indexed: 01/09/2023]
Abstract
PURPOSE Data concerning reperfusion strategies of intracranial atherosclerosis-related occlusion (ICARO) and clinico-angiographic outcomes remain scarce, particularly in Caucasians. We aim to compare the reperfusion rate and functional outcome between reperfusion strategies in the setting of the ICARO. METHODS Retrospective analysis of prospectively maintained endovascular thrombectomy (EVT) registries at three high-volume stroke centers were retrospectively analyzed for consecutive ICARO patients from January 2015 to December 2019. We defined ICARO as any fixed high-degree (> 70%) focal narrowing or stenosis of any degree with a perpetual tendency for reocclusion. We categorized reperfusion strategies into four groups: EVT [group 1], balloon angioplasty [(BAp), group 2], placement of self-expandable stents [(SES), group 3], and BAp combined with implantation of SES; or direct placement of balloon mounted stents (BMS) [(BAp-SES/BMS), group 4]. We evaluated the association with the successful reperfusion [mTICI 2b - 3] and favorable outcome [mRS 0-2] with logistic regression analysis. RESULTS Out of 2550 EVT, 124 patients (median age, 70 (61-80) years; 76 men) with ICARO and 130 reperfusion attempts [36 EVT, 38 BAp, 17 SES, and 39 BAp + SES/BMS] were analyzed. SES implantation showed the highest frequency of post-procedural symptomatic intracranial hemorrhage [(18%, 3/17), p = .03]; however, we observed no significant differences in the mortality rate. Overall, we achieved successful reperfusion in 71% (92/130) and favorable outcomes in 42% (52/124) of the patients. BAp + SES/BMS was the only independent predictor of the final successful reperfusion [aOR, 4.488 (95% CI, 1.364-14.773); p = .01], which was significantly associated with the 90-day favorable outcome [aOR, 10.837 (95% CI, 3.609-32.541); p = < .001] after adjustment for confounding variables between the reperfusion strategies. CONCLUSION Among patients with ICARO, the rescue angioplasty stenting effectively contributed to higher odds of successful reperfusion with no increased risk for intracranial hemorrhage.

Abstract
Symptomatic intracranial atherosclerotic disease (ICAD) is a globally challengeable disease. In the past 20 years, people have made a huge effort to deal with the problem including using endovascular technology and aggressive medical therapy. However, the efficacy of these methods seemed to be limited. The recent China angioplasty and stenting for symptomatic intracranial severe stenosis (CASSISS) did not support the addition of percutaneous transluminal angioplasty and stenting to medical therapy for the treatment of patients with symptomatic severe ICAD. So where are we heading in the post-CASSISS era?

Abstract
The CASSISS trial (China Angioplasty & Stenting for Symptomatic Intracranial Severe Stenosis), recently published in JAMA, is the most recent of several randomized controlled trials that have failed to show a benefit of percutaneous angioplasty and stenting over medical therapy for the prevention of stroke due to intracranial atherosclerotic stenosis. Current practice guidelines recommended that percutaneous angioplasty and stenting should not be performed routinely as a treatment for stroke prevention in patients with intracranial atherosclerotic stenosis. The CASSISS trial reinforces those recommendations and will not change practice, but it may provide some important lessons for future trial design.

Balloon Angioplasty Combined with Tirofiban as a First-Line Rescue Treatment After Failed Mechanical Thrombectomy for Middle Cerebral Artery Occlusion with Underlying Atherosclerosis. World Neurosurg 2022; 166:e306-e312. [PMID: 35809841 DOI: 10.1016/j.wneu.2022.07.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 06/30/2022] [Accepted: 07/01/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVE The standard rescue modality for patients with intracranial atherosclerotic stenosis after failed mechanical thrombectomy (MT) is not well established. We evaluated the safety and efficacy of balloon dilation in combination with tirofiban as the first-line salvage therapy when MT failed in these patients. METHODS We retrospectively analyzed the records of 47 patients admitted between January 2018 and June 2021, with middle cerebral artery atherosclerotic occlusion, who underwent balloon angioplasty in combination with tirofiban as the first-line salvage therapy after the failure of MT. The recanalization outcome, procedure-related complications, symptomatic intracranial hemorrhage, and functional outcome at 90 days were reviewed. RESULTS Recanalization with a modified Thrombolysis in Cerebral Infarction grade of 2b-3 was achieved in 41 (87.2%) of the 47 patients. Acute stents were deployed in another 6 patients who did not achieve successful re-perfusion after balloon angioplasty. Successful recanalization was achieved in 3 of them. One patient (2.1%, 1/47) experienced re-occlusion several days later due to the withdrawal of antiplatelet therapy for parenchymal hematoma. Seven patients (14.9%, 7/47) underwent stent angioplasty in the stable stage (range: 1-2 months) because severe residual stenosis was detected on follow-up imaging. There was only one event of periprocedural complication, namely ectopic migration of emboli. The good functional outcome rate was 55.3% (26/47), without the events of symptomatic intracranial hemorrhage and mortality. CONCLUSIONS Balloon angioplasty in combination with tirofiban is safe and effective for middle cerebral artery atherosclerotic occlusion after the failure of MT.

Abstract
The aim of the present European Stroke Organisation guideline is to provide clinically useful evidence-based recommendations on the management of patients with intracranial atherosclerotic disease (ICAD). The guidelines were prepared following the Standard Operational Procedure of the European Stroke Organisation guidelines and according to GRADE methodology. ICAD represents a major cause of ischemic stroke worldwide, and patients affected by this condition are exposed to a high risk for future strokes and other major cardiovascular events, despite best medical therapy available. We identified 11 relevant clinical problems affecting ICAD patients and formulated the corresponding Population Intervention Comparator Outcomes (PICO) questions. The first two questions refer to the asymptomatic stage of the disease, which is being increasingly detected thanks to the routine use of noninvasive vascular imaging. We were not able to provide evidence-based recommendations regarding the optimal detection strategy and management of asymptomatic ICAD, and further research in the field is encouraged as subclinical ICAD may represent a big opportunity to improve primary stroke prevention. The second block of PICOs (3-5) is dedicated to the management of acute large vessel occlusion (LVO) ischemic stroke caused by ICAD, a clinical presentation of this disease that is becoming increasingly relevant and problematic, since it is associated with more refractory endovascular reperfusion procedures. An operational definition of probable ICAD-related LVO is proposed in the guideline. Despite the challenging context, no dedicated randomized clinical trials (RCTs) were identified, and therefore the guideline can only provide with suggestions derived from observational studies and our expert consensus, such as the escalated use of glycoprotein IIb-IIIa inhibitors and angioplasty/stenting in cases of refractory thrombectomies due to underlying ICAD. The last block of PICOs is devoted to the secondary prevention of patients with symptomatic ICAD. Moderate-level evidence was found to recommend against the use of oral anticoagulation as preferred antithrombotic drug, in favor of antiplatelets. Low-level evidence based our recommendation in favor of double antiplatelet as the antithrombotic treatment of choice in symptomatic ICAD patients, which we suggest to maintain during 90 days as per our expert consensus. Endovascular therapy with intracranial angioplasty and or stenting is not recommended as a treatment of first choice in high-grade symptomatic ICAD (moderate-level evidence). Regarding neurosurgical interventions, the available evidence does not support their use as front line therapies in patients with high-grade ICAD. There is not enough evidence as to provide any specific recommendation regarding the use of remote ischemic conditioning in ICAD patients, and further RCTs are needed to shed light on the utility of this promising therapy. Finally, we dedicate the last PICO to the importance of aggressive vascular risk factor management in ICAD, although the evidence derived from RCTs specifically addressing this question is still scarce.

Abstract
Background Vascular intracranial stenosis (IS) is a significant cause of acute ischemic stroke (AIS). This single-center study aims to show that symptomatic IS treatment by using the Neuroform Atlas stent (Stryker neurovascular, Kalamazoo, MI, USA) could be effective in reducing vessel stenosis. Methods Ten patients affected by AIS or TIA, in the vascular territory of high-grade intracranial atherosclerotic lesions (>70% of vessel stenosis), older than 18-year-old, were treated by implanting a Neuroform Atlas stent (diameter of 4.5mm in 80% and 4mm in 20%). 70% of the patients underwent pre-stenting intracranial angioplasty. Results Patients were between 54.8 and 83 years old (mean 68.46y ± 8.44y), 70% males and 30% females. At admission, 50% of all patients had an AIS and 50% a TIA. Restoration of the stenotic lumen was obtained after the endovascular procedure. The percentage mean of vascular stenosis was 83.7% ± 6.09% before treatment (t0), 52.2% ± 10.42% at the end of treatment (t1) and 46.2% ± 8.28% at the follow-up (t2). The IS percentage mean reduction between t0 and t1 was 31.5% ± 7.31%, and between t1 and t2 was 6% ± 5.47%, t0 and t2 of 37.5% ± 7.38%. Percentage reduction of IS was highly significant between time t0 and t1 (p = 0.005), and t0 and t2 (p = 0.005), also with a significant reduction between t1 and t2 (p = 0.012). No patient had experienced an increase of the ischemic area in the vascular territory of the target vessel at 3 months from the initial assessment. 10% of patients experienced a 3-months negative outcome (mRS = 5), 90% experienced a favorable outcome (mRS ≤2). Conclusions Intracranial stenosis endovascular treatment with Neuroform Atlas stent provides encouraging results, with a statistically significant association between the vascular caliber improvement and the endovascular treatment.

Abstract
OBJECTIVE To investigate whether significant differences exist in recanalization rates and primary outcomes between patients who undergo mechanical thrombectomy alone versus those who undergo mechanical thrombectomy with acute intracranial stenting. METHODS Through the utilization of a prospectively collected endovascular database at a comprehensive stroke center between 2012 and 2020, variables such as demographics, co-morbid conditions, symptomatic intracerebral hemorrhage, mortality rate at discharge, and good/poor outcomes in regard to modified thrombolysis in cerebral infarction score and modified Rankin Scale were examined. The outcomes between patients receiving acute intracranial stenting + mechanical thrombectomy and patients that underwent mechanical thrombectomy alone were compared. RESULTS There were a total of 420 acute ischemic stroke patients who met criteria for the study (average age 70.6 ± 13.01 years; 46.9% were women). Analysis of 46 patients from the acute stenting + mechanical thrombectomy group (average age 70.34 ± 13.75 years; 37.0% were women), and 374 patients from the mechanical thrombectomy alone group (average age 70.64 ± 12.92 years; 48.1% were women). Four patients (8.7%) in the acute stenting + mechanical thrombectomy group experienced intracerebral hemorrhage versus 45 patients (12.0%) in the mechanical thrombectomy alone group (p = 0.506); no significant increases were noted in the median length of stay (7 vs 8 days; p = 0.208), rates of modified thrombolysis in cerebral infarction 2B-3 recanalization (p = 0.758), or good modified Rankin Scale scores (p = 0.806). CONCLUSION Acute intracranial stenting in addition to mechanical thrombectomy was not associated with an increase in overall length of stay, intracerebral hemorrhage rates, or any change in discharge modified Rankin Scale. Further research is required to determine whether mechanical thrombectomy and acute intracranial stenting in acute ischemic stroke patients is unsafe.

Abstract
BACKGROUND AND PURPOSE Stroke recurrence is high in patients with symptomatic intracranial stenosis despite best medical treatment. Based on evidence from past studies using previous stent generations, elective intracranial stenting (eICS) is considered in a minority of patients. This study aims to report on experience performing eICS with a novel device combination. METHODS We retrospectively reviewed data from three high volume stroke centers and analyzed patients that were treated with eICS for symptomatic intracranial stenosis using the Acclino (flex) stent and the NeuroSpeed balloon catheter (Acandis GmbH, Pforzheim, Germany). Study endpoints were periprocedural rates of stroke regardless of territory or death at discharge and at the time of follow-up after eICS. Safety evaluation included asymptomatic and symptomatic intracranial hemorrhage, serious adverse events related to the intervention, and evaluation of stent patency at the time of follow-up. RESULTS The median age of patients that met the inclusion criteria (n=76) was 69 years. Target vessels were located in the anterior circulation in 55.3% (42/76) of patients. The periprocedural stroke rate was 6.5% (fatal stroke 2.6%; non-fatal stroke 3.9%) at discharge after eICS. Asymptomatic intracranial hemorrhage was observed in 5.2% (4/76) of patients. Follow-up DSA revealed in-stent restenosis of 25% (15/60), and percutaneous transluminal angioplasty was performed again in 11.6% (7/60) of patients. CONCLUSION Stenting for symptomatic intracranial stenosis with the Acclino (flex)/NeuroSpeed balloon catheter seemed to be safe and reinforces eICS as an endovascular therapy option for secondary stroke prevention. Future studies are warranted to confirm these findings and investigate antithrombotic strategies and in-stent restenosis to minimize periprocedural complications and guarantee long term stent patency.

Abstract
Background and Purpose: Recently, acute intracranial stenting (ICS) has gained more interest as a potential bailout strategy for large vessel occlusions (LVO) that are refractory to thrombectomy. However, there are currently no reports on ICS in patients with moderately severe stroke discussing the question if implementing a permanent stent is feasible and leads to improved recanalization after failed thrombectomy. Methods: We analyzed a large multicenter database of patients receiving ICS for anterior circulation LVO after failed thrombectomy. Inclusion criteria were defined as: Moderately severe stroke (National Institute Health Stroke Scale (NIHSS) ≤9 on admission), anterior circulation LVO, acute ICS after failed stent retriever MT. Primary endpoint was the rate of improved successful recanalization after ICS defined as a modified Thrombolysis In cerebral Infarction (mTICI) score≥2b. Favorable neurological outcome was defined as an early neurological improvement (ENI) of 4 points or reaching 0 with respect to baseline NIHSS. Results: Forty-one patients met the inclusion criteria. A median of 2 retrievals were performed (IQR 1-4) prior decision-making for ICS. ICS led in 90.2% (37/41) of cases to a final mTICI≥2b with significant improvement (p < 0.001) after the last retrieval attempt. The median NIHSS decreased (p = 0.178) from 7 (IQR 3.5-8) on admission to 2.5 (IQR 0-8.25) at discharge. ENI was observed in 47.4% (18/38). sICH occurred in 4.8% (2/41). Conclusion: ICS after failed thrombectomy appears to effectively improve recanalization rates in patients with moderately severe strokes. Thus, ICS should be considered also for patients with baseline NIHSS ≤9 if thrombectomy fails.
