Mechanical Thrombectomy Global Access For Stroke (MT-GLASS): A Mission Thrombectomy (MT-2020 Plus) Study.

BACKGROUND: Despite the well-established potent benefit of mechanical thrombectomy (MT) for large vessel occlusion (LVO) stroke, access to MT has not been studied globally. We conducted a worldwide survey of countries on 6 continents to define MT access (MTA), the disparities in MTA, and its determinants on a global scale. METHODS: Our survey was conducted in 75 countries through the Mission Thrombectomy 2020+ global network between November 22, 2020, and February 28, 2021. The primary end points were the current annual MTA, MT operator availability, and MT center availability. MTA was defined as the estimated proportion of patients with LVO receiving MT in a given region annually. The availability metrics were defined as ([current MT operators×50/current annual number of estimated thrombectomy-eligible LVOs]×100 = MT operator availability) and ([current MT centers×150/current annual number of estimated thrombectomy-eligible LVOs]×100= MT center availability). The metrics used optimal MT volume per operator as 50 and an optimal MT volume per center as 150. Multivariable-adjusted generalized linear models were used to evaluate factors associated with MTA. RESULTS: We received 887 responses from 67 countries. The median global MTA was 2.79% (interquartile range, 0.70-11.74). MTA was <1.0% for 18 (27%) countries and 0 for 7 (10%) countries. There was a 460-fold disparity between the highest and lowest nonzero MTA regions and low-income countries had 88% lower MTA compared with high-income countries. The global MT operator availability was 16.5% of optimal and the MT center availability was 20.8% of optimal. On multivariable regression, country income level (low or lower-middle versus high: odds ratio, 0.08 [95% CI, 0.04-0.12]), MT operator availability (odds ratio, 3.35 [95% CI, 2.07-5.42]), MT center availability (odds ratio, 2.86 [95% CI, 1.84-4.48]), and presence of prehospital acute stroke bypass protocol (odds ratio, 4.00 [95% CI, 1.70-9.42]) were significantly associated with increased odds of MTA. CONCLUSIONS: Access to MT on a global level is extremely low, with enormous disparities between countries by income level. The significant determinants of MT access are the country's per capita gross national income, prehospital LVO triage policy, and MT operator and center availability.

INSTRuCT: Protocol, Infrastructure, and Governance.

Background and Purpose: Very few large scale multicentric stroke clinical trials have been done in India. The Indian Council of Medical Research funded INSTRuCT (Indian Stroke Clinical Trial Network) as a task force project with the objectives to establish a state-of-the-art stroke clinical trial network and to conduct pharmacological and nonpharmacological stroke clinical trials relevant to the nation and globally. The purpose of the article is to enumerate the structure of multicentric stroke network, with emphasis on its scope, challenges and expectations in India. Methods: Multiple expert group meetings were conducted by Indian Council of Medical Research to understand the scope of network to perform stroke clinical trials in the country. Established stroke centers with annual volume of 200 patients with stroke with prior experience of conducting clinical trials were included. Central coordinating center, standard operating procedures, data and safety monitoring board were formed. Discussion: In first phase, 2 trials were initiated namely, SPRINT (Secondary Prevention by Structured Semi-Interactive Stroke Prevention Package in India) and Ayurveda treatment in the rehabilitation of patients with ischemic stroke in India (RESTORE [Rehabilitation of Ischemic stroke Patients in India: A Randomized controlled trial]). In second phase, 4 trials have been approved. SPRINT trial was the first to be initiated. SPRINT trial randomized first patient on April 28, 2018; recruited 3048 patients with an average of 128.5 per month so far. The first follow-up was completed on May 27, 2019. RESTORE trial randomized first patient on May 22, 2019; recruited 49 patients with an average of 3.7 per month so far. The first follow-up was completed on August 30, 2019. Conclusions: In next 5 years, INSTRuCT will be able to complete high-quality large scale stroke trials which are relevant globally.

Factors Affecting the Effective Management of Acute Stroke: A Prospective Observational Study.

BACKGROUND: Stroke, characterized by sudden loss of cerebral function, is among one of the leading cause of death and disability world over. The newer treatment modalities have changed the landscape of stroke treatment but are very much time bound. AIM: To characterize pre-hospital and in-hospital factors affecting acute stroke management thus defining lacunae in stroke management. SUBJECTS AND METHODS: A prospective observational study, conducted at the emergency department of a tertiary care center in southern India from August 2015 to July 2016. All stroke patients presenting within first 24 hours of onset were included. A pre -defined Knowledge-Attitude-Practice (KAP) questionnaire was used. RESULTS: Total of 133 patients were eligible out of which 28 were excluded for various reasons. Majority were >60 years age and male (61%). About 60% arrived within window. Distance from the hospital was one of the major factors for arrival within the window period. When compared by KAP questionnaire, bystanders of those arriving within window period had better awareness of stroke symptoms. CONCLUSIONS: Improving awareness of stroke symptoms and increasing availability of EMS is likely increase chances of stroke patients receiving appropriate acute management.

Stroke in Young-Dilative Arteriopathy: A Clue to Late-Onset Pompe's Disease?

IMPORTANCE: In almost a third of stroke in young cases, etiology remains unclear. We report a radiological entity which might give a clue toward detection of late onset Pompe's disease in some cases. OBSERVATION: Here we report two cases of stroke in young in which evaluation led to diagnosis of late onset Pompe's disease. Both patients presented with recurrent stroke. On evaluation, one of them was found to have slowly progressive predominantly proximal quadriparesis. His muscle biopsy showed Pompe's disease and had dolichoectasia of posterior circulation vessels. The other patient did not have any muscle weakness. Detailed workup for stroke in young was negative, but as angiogram showed intracranial vessel dolichoectasia, he was also investigated and found to have Pompe's disease. CONCLUSIONS AND RELEVANCE: We conclude that dolichoectasia of intracranial vessels in cases with stroke in young, with or without muscle weakness, should raise a differential of late onset Pompe's disease. This being one of the few treatable disorders makes the diagnosis all the more important.

Endovascular treatment of acute ischemic stroke: an Indian experience from a tertiary care center.

BACKGROUND: In India, late presentation due to poor awareness about stroke precludes intravenous thrombolysis (IVT). Endovascular therapy can be used in these circumstances. We present our experience of endovascular treatment of acute ischemic stroke in a tertiary care center. AIM: Endovascular treatment of acute ischemic stroke in a tertiary care center in India. SETTINGS, DESIGN, MATERIALS, AND METHODS: The study period was from 2009 till 2013. Consecutive patients with acute ischemic stroke, who either had contraindications to IVT or had failed IVT, underwent endovascular treatment. Before the publication of interventional management of stroke 3 results, we took a few patients, with large vessel occlusions, directly for endovascular treatment. After imaging, patients were considered for endovascular treatment, using either intra-arterial thrombolysis or mechanical thrombectomy, if there was a documented large vessel occlusion. Outcome was assessed at 3 months using the modified Rankin Scale. STATISTICAL ANALYSIS: Statistical analysis was done using the Statistical Package for the Social Sciences 17.0 software. RESULTS: A total of 45 patients underwent endovascular treatment. The mean age at presentation was 49 years, median National Institutes of Health Stroke Scale (NIHSS) was 19 and the most common site was the middle cerebral artery (23 patients). Solitaire™ stentriever was used in 33 patients. The median pre-procedure Thrombolysis In Myocardial Infarction (TIMI) score was 0 and the median post-procedure TIMI score was 3. Nine patients underwent decompressive craniectomy. On follow-up at 3 months, the median Modified Rankin Scale (mRS) was 0. Eight patients died during 3 months following stroke. CONCLUSION: Endovascular treatment of acute ischemic stroke is a viable treatment option in patients who either have contraindications to IVT or who fail IVT.

Endovascular Treatment for Cerebral Venous Sinus Thrombosis: Comparison among Different Endovascular Procedures.

Background: Cerebral venous sinus thrombosis (CVST) is a rare, treatable cause of stroke. Even though CVST has an established medical treatment, 15% of patients remain refractory to treatment. These patients may be candidates for endovascular treatment (EVT), yet the selection of patients remains a challenge. The study aims to understand the profile and outcome of patients treated with EVT and the type of procedure associated with good outcomes. Methods: This is a single-center, retrospective analysis of CVST patients who underwent EVT from 2009 till 2022. Patients who received only medical management were excluded. Modified Rankin Scale (mRS) ≤2 at 3 months was taken as the primary outcome. Secondary outcomes assessed were hospital stay, death, recurrence, mRS ≤ 2 at discharge, and angiographic recanalization. Results: Fifty-two patients were included. Twenty-eight (53.8%) were males; the mean age was 33.3 ± 12.3 years. Headache (n = 44, 84.6%) predominated among the symptoms. The common risk factors were anemia (n = 13, 25.5%) and hyperhomocysteinemia (n = 13, 25.5%). Worsening of sensorium (n = 21, 40.3%) and non-improvement of symptoms (n = 15, 28.8%) were the common indications for the procedure. Twenty-five (48.1%) people underwent in situ thrombolysis (IST). Death occurred in eight (15.3%) patients. Thirty-six (73.5%; 36/49) patients had a good outcome at 3 months. IST had a significantly better outcome (mRS ≤ 2, n = 20, 80%) compared to other procedures (P = 0.04). Hospital stay was lesser in the IST subgroup, but without statistical significance. Midline shift >5 mm (odds ratio [OR] 6.8 [1.5-30.9], P = 0.01) and Glasgow Coma Scale <9 before the procedure (OR 27.2 [3.1-236.4], P = 0.002) predicted bad outcomes at 3 months. Female gender (OR 4.5 [1.07-8.8], P = 0.03), presence of altered sensorium (OR 10.2 [1.2-87.5], P = 0.01), encephalopathic syndrome (P = 0.02), presence of parenchymal bleed (OR 3.7 [0.9-4.5], P = 0.04), and midline shift (OR 4.8 [1.1-20.2], P = 0.03) were associated with poor outcome at discharge. Conclusion: EVT yielded good outcomes in carefully selected, medically refractory patients of CVST. IST performed well compared to other procedures.

Endovascular Therapy in Large Core Ischemic Strokes: Real-World Indian Experience.

BACKGROUND: Large core acute ischemic strokes have predominantly been excluded from endovascular therapy (EVT) studies due to perceived higher risks of hemorrhage and poorer functional outcomes. However, recent randomized controlled trials (RCTs) indicate that EVT for large vessel occlusion (LVO) strokes improves functional outcomes compared to medical management alone, despite higher hemorrhagic transformation rates, with no corresponding increase in symptomatic intracerebral hemorrhage (sICH) rates. The real-world outcomes of this intervention in Indian patients remain underexplored. OBJECTIVES: To evaluate the real-world outcomes of EVT for large core acute ischemic strokes with LVO in an Indian population. METHODS: We conducted a single-center, retrospective observational study using a 7 years prospective database of EVT in anterior circulation stroke patients. Patients with Alberta Stroke Program Early Computed Tomography Score (ASPECTS) of 3-5 were included. Clinical and radiologic data were analyzed, with the primary endpoint being 90-day modified Rankin scale (mRS) scores. Safety outcomes included rates of sICH and mortality. Descriptive statistical analysis was done using Microsoft Excel. RESULTS: The study included 25 patients who met the inclusion criteria. Mean age of patients was 52.9 ± 14.3 years, and there were 13 (52%) males. Median ASPECTS was 5 (interquartile range 4-5). Successful recanalization, classified by modified Thrombolysis in Cerebral Infarction score, was 92%. Good functional recovery, that is, 90-day mRS 0-3, was achieved in nine (36%) patients. Safety outcomes: sICH was seen in four (16%) and mortality was reported in nine (36%) patients. CONCLUSIONS: Our results reaffirm findings from RCTs, provide updated real-world evidence, and suggest that EVT is a viable option to be considered in selected patients with large core ischemic infarcts.

Mechanical Thrombectomy: Review.

Large vessel occlusion stroke contributes to disability and mortality out of proportion to its incidence. Over time it was noted that intravenous thrombolysis alone was not sufficient for this stroke type. Slowly, endovascular approach and mechanical clot retrieval have come out to be the biggest advances in the field of neurology as well as modern medicine. Although the careful selection of patients is needed as standardized by landmark trials. At the same time, thrombectomy is now being studied in patients excluded by previous trials and is seemingly coming out be effective in the vast majority of patients with large vessel occlusions. Further, techniques and devices are getting refined day by day to achieve the maximum possible benefit.

Comparing Bridging Thrombolysis with Direct Thrombectomy in Stroke due to Large Vessel Occlusion- Indian Experience (LVO-Direct).

Objectives: Intravenous thrombolysis alone has poor recanalization rates in large vessel occlusion strokes. Bridging thrombolysis has evolved as a standard treatment approach in emergent large vessel occlusions. Patients who undergo thrombectomy have a higher probability of favorable outcomes irrespective of the use of prior intravenous thrombolysis. Our aim was to compare bridging thrombolysis with direct thrombectomy in ischemic stroke due to large vessel occlusion. Methods: We included patients from our stroke registry, with large vessel occlusion strokes, presenting <4.5 hr from onset. Bridging thrombolysis was the standard approach. Direct thrombectomy was done in patients with contraindications to intravenous thrombolysis. The primary outcome was the modified Rankin scale at 3 months. Secondary outcomes were National Institute of Health Stroke Scale at 24 hr post-procedure, door to puncture time, puncture to recanalization time, the extent of recanalization, and the number of passes required. Safety outcomes were any occurrence of intracranial hemorrhage or other complications related to procedure or death. Logistic regression analysis was used to find the factors affecting the outcome. Results: Total 76 patients were included, 29 underwent bridging thrombolysis and 47 underwent direct thrombectomy. A favorable outcome (mRS 0-2) was achieved in 19 (65.5%) patients in the bridging group and 25 (58.1%) patients in the direct group (P = 0.4, Chi-square test). There was no significant difference in any of the secondary outcomes as well. Symptomatic intracranial hemorrhage occurred in 2 (2.6%) patients and a total of 10 (13.9%) were dead at 3-month follow-up, comparable in both groups. Conclusion: Direct thrombectomy has comparable outcomes to bridging thrombolysis in emergent large vessel occlusions.

Rescue Stenting for Refractory Large Vessel Occlusions in the Thrombectomy Era: Intracranial Use of Coronary Stents in Low-mid Economic Settings.

BACKGROUND:  Failed mechanical thrombectomy due to a refractory emergent large vessel occlusion (RELVO) in patients presenting with an acute stroke poses a major challenge to the outcomes. OBJECTIVE:  We demonstrate the use of coronary stents in the intracranial circulation as rescue stenting for an already expensive mechanical thrombectomy procedure in a mid-low socioeconomic setting. METHODS:  A retrospective, multicenter study was conducted between December 2015 and January 2021. The studied cohort were patients who required the use of a rescue stenting using a coronary stent for emergent large vessel occlusion to avoid failed recanalization. Failed recanalization was defined as failed vessel recanalization after at least two passes. Patient demographic data, procedure specifics, type of stent used, and procedural outcomes were collected. RESULTS:  A total of 26 patients with acute ischemic stroke were included from eight different centers across India. Out of 26 patients, 19 (73.0%) were male and seven were female (26.9%). The mean age was 53.6 years, the youngest patient was 23 years old and the eldest was 68 years old. Seven patients (26.9%) had posterior circulation stroke due to occlusion of the vertebral or basilar artery and 19 patients (73.0%) had anterior circulation stroke median NIHSS at presentation was 16 (range 10 to 28) in anterior circulation stroke and 24 (range 16 to 30) in posterior circulation stroke. Intravenous thrombolysis with tissue plasminogen activator (IV tPA) was given in three patients (11.5%). The hospital course of two patients was complicated by symptomatic intracranial hemorrhage (sICH), which was fatal. Favorable revascularization outcome and favorable functional outcome was achieved in 22 patients (84.6%), three patients passed away (11.5%), and one patient was lost to follow up. CONCLUSIONS:  Overall, our study finds that rescue stenting using coronary stents can potentially improve outcomes in refractory large vessel occlusions while minimizing costs in low-mid economic settings.

Endovascular treatment for acute ischemic stroke using solitaire stent: temporary endovascular bypass, a novel technique.

Early restoration of flow to perfuse salvageable brain tissue has been shown to significantly reduce the morbidity and mortality of ischemic stroke. Several mechanical devices have shown promising results in patients with large vessel occlusive stroke. Solitaire revascularization device (ev3, Inc., Irvine, California) is a recoverable self-expanding thrombectomy device that can also be used as a temporary endovascular bypass. We report a patient in whom solitaire aneurysm bridging stent was used as a temporary bypass procedure to recanalize carotid T occlusion patient with good functional outcome.

Rescue Strategies in Anterior Circulation Stroke with Failed Mechanical Thrombectomy-A Retrospective Observational Study (RAFT).

Context: Recanalization failure rate in mechanical thrombectomy (MT) for large vessel occlusions is up to 30%. Outcome greatly depends on recanalization success and, thus, there is an urgent need to adopt new strategies to improve recanalization. Aims: To report on the feasibility, safety, and outcome of rescue strategies (stenting and/or angioplasty) in cases of failed MT for acute ischemic stroke (AIS) in anterior circulation. Materials and Methods: It was a retrospective observational study where patients undergoing MT were divided into two groups. The first group (MT-only) was of patients who had undergone only MT with the standard tools (stentriever and/or aspiration). The second group (MT-plus) consisted of patients who underwent a rescue procedure after failure of the standard MT. The two groups were compared based on the demographics, risk factors, stroke severity, and the extent of infarct on imaging. The angiographic findings, procedural details, periprocedural care, and angiographic and clinical outcome were also compared. Results: Out of 181 cases, 142 were in MT-only while 39 were included in MT-plus group. The two groups had comparable baseline stroke severity, extent of infarct on imaging and door to puncture time. The MT-plus patients had significantly longer time of onset and puncture to recanalization time. The clinical outcome was favorable in both groups with 57.7% and 59% patients achieving mRS 0-2 in MT-only and MT-plus groups, respectively. Successful recanalization was achieved in 80.3% and 89.7% in MT-only and MT-plus groups, respectively. There was no significant increase in symptomatic intracranial hemorrhage and mortality after rescue procedures. Conclusions: Rescue stenting and/or angioplasty after failed MT is a safe and effective recanalization method for AIS in anterior circulation without increasing mortality or morbidity.

REtrospective Multicenter INdian Study of Derivo Embolization Device (REMIND): Periprocedural Safety.

PURPOSE: The treatment of aneurysms with characteristics such as complex morphology, fusiform, blister-like, wide neck, or large size has been revolutionized with the introduction of flow diverters. Though flow diverters have several advantages over coiling, they also have certain important disadvantages such as the lack of immediate protection against rupture, the risk of ischemic stroke, the need for antiplatelet therapy, and long latency for complete effect. The Derivo Embolization Device (DED) is a second-generation self-expanding device that is claimed to be less thrombogenic than conventional devices. We retrospectively evaluated the periprocedural safety and risks associated with the DED across 5 centers in India. MATERIALS AND METHODS: This is a multicentric, retrospective, observational study of DED, conducted at 5 high volume endovascular therapy centers in India from May 2018 to June 2020. Periprocedural demographic, clinical, and angiographic data were collected from a retrospective review of patient charts. RESULTS: A total of 96 patients, including 56 (58.3%) females, aged between 16-80 years (60±12.7 years) harboring 106 aneurysms were studied. Seven (7.3%) were noted to harbor multiple aneurysms: 6 had 3 aneurysms each, while 1 patient had 5 aneurysms. The following aneurysm characteristics were noted: average size, 9.8±8.2 mm; average neck size, 6.9±8.5 mm; wide-necked (>4 mm), 63 (59.4%); giant (>25 mm), 8 (7.5%); and anterior circulation location, 98 (92.5%). Eighteen (17%) of these were ruptured. Additional balloon angioplasty was performed in 5 (5.2%) patients. Intraprocedural problems were encountered in 3 (3.1%), of which only 1 had clinical implications, the device fish-mouthing with stent thrombosis resulting in a malignant middle cerebral artery territory infarction. The modified Rankin scale at 3 months was worse in 1 patient. CONCLUSION: DED is a newer generation flow diverter stent with a low periprocedural complication rate.

Myoclonus-Ataxia Syndrome Associated with COVID-19.

Neurological manifestations of coronavirus disease (COVID-19) have increasingly been reported since the onset of the pandemic. Herein, we report a relatively new presentation. A patient in the convalescence period following a febrile illness with lower respiratory tract infection (fever, myalgia, nonproductive cough) presented with generalized disabling myoclonus, which is phenotypically suggestive of brainstem origin, along with additional truncal cerebellar ataxia. His neurology work-ups, such as brain MRI, electroencephalography, serum autoimmune and paraneoplastic antibody testing, were normal. His CT chest scan revealed right lower lung infiltrates, and serological and other laboratory testing did not show evidence of active infection. COVID-19 titers turned out to be strongly positive, suggestive of post-COVID-19 lung sequelae. He responded partially to antimyoclonic drugs and fully to a course of steroids, suggesting a para- or postinfectious immune-mediated pathophysiology. Myoclonusataxia syndrome appears to be a neurological manifestation of COVID-19 infection, and knowledge regarding this phenomenon should be increased among clinicians for better patient care in a pandemic situation.

COVID-19-related strokes are associated with increased mortality and morbidity: A multicenter comparative study from Bengaluru, South India.

BACKGROUND: COVID-19-related strokes are increasingly being diagnosed across the world. Knowledge about the clinical profile, imaging findings, and outcomes is still evolving. Here we describe the characteristics of a cohort of 62 COVID-19-related stroke patients from 13 hospitals, from Bangalore city, south India. OBJECTIVE: To describe the clinical profile, neuroimaging findings, interventions, and outcomes in COVID-19-related stroke patients. METHODS: This is a multicenter retrospective study of all COVID-19-related stroke patients from 13 hospitals from south India; 1st June 2020-31st August 2020. The demographic, clinical, laboratory, and neuroimaging data were collected along with treatment administered and outcomes. SARS-CoV-2 infection was confirmed in all cases by RT-PCR testing. The data obtained from the case records were entered in SPSS 25 for statistical analysis. RESULTS: During the three-month period, we had 62 COVID-19-related stroke patients, across 13 centers; 60 (97%) had ischemic strokes, while 2 (3%) had hemorrhagic strokes. The mean age of patients was 55.66 ± 13.20 years, with 34 (77.4%) males. Twenty-six percent (16/62) of patients did not have any conventional risk factors for stroke. Diabetes mellitus was seen in 54.8%, hypertension was present in 61.3%, coronary artery disease in 8%, and atrial fibrillation in 4.8%. Baseline National Institutes of Health Stroke Scale score was 12.7 ± 6.44. Stroke severity was moderate (National Institutes of Health Stroke Scale 5-15) in 27 (61.3%) patients, moderate to severe (National Institutes of Health Stroke Scale 16-20) in 13 (20.9%) patients and severe (National Institutes of Health Stroke Scale 21-42) in 11 (17.7%) patients. According to TOAST classification, 48.3% was stroke of undetermined etiology, 36.6% had large artery atherosclerosis, 10% had small vessel occlusion, and 5% had cardioembolic strokes. Three (5%) received intravenous thrombolysis with tenecteplase 0.2 mg/kg and 3 (5%) underwent mechanical thrombectomy, two endovascular and one surgical. Duration of hospital stay was 16.16 ± 6.39 days; 21% (13/62) died in hospital, while 37 (59.7%) had a modified Rankin score of 3-5 at discharge. Hypertension, atrial fibrillation, and higher baseline National Institutes of Health Stroke Scale scores were associated with increased mortality. A comparison to 111 historical controls during the non-COVID period showed a higher proportion of strokes of undetermined etiology, higher mortality, and higher morbidity in COVID-19-related stroke patients. CONCLUSION: COVID-19-related strokes are increasingly being recognized in developing countries, like India. Stroke of undetermined etiology appears to be the most common TOAST subtype of COVID-19-related strokes. COVID-19-related strokes were more severe in nature and resulted in higher mortality and morbidity. Hypertension, atrial fibrillation, and higher baseline National Institutes of Health Stroke Scale scores were associated with increased mortality.

Carotid Artery Stenting and Its Impact on Cognitive Function: A Prospective Observational Study.

PURPOSE: Carotid artery stenting (CAS) has evolved as a first-line therapeutic option for carotid revascularization in indicated patients for stroke prevention, but there is still a lack of data on its effect on cognitive function (CF), especially among Indian patients. To determine the effect of CAS on CF and to study the immediate and delayed complications of CAS in Indian patients. MATERIALS AND METHODS: This was a prospective, observational, single-center study. CF was assessed using Addenbrooke's cognitive examination version III (ACE) before and 3 months after stenting. The demographic and clinical parameters were also assessed. A follow-up evaluation after 3 months was done to compare CF and to observe the occurrence of any complications. RESULTS: Out of 31 patients, 3 were lost to follow up. There were no immediate or delayed procedure-related complications. There was a statistically significant improvement in overall ACE score and memory before and after stenting. On subgroup analysis of those with and without strokes, there was a significant improvement in visuospatial function and mean ACE score. Those with left CAS had significant improvement in memory, visuospatial, language, and ACE scores than right CAS. CONCLUSION: CAS was associated with significant improvement in CF in patients.

Consensus Statement - Suggested Recommendations for Acute Stroke Management during the COVID-19 Pandemic: Expert Group on Behalf of the Indian Stroke Association.

The ongoing pandemic of COVID-19 is a global public health emergency. This has led to challenges for healthcare facilities to optimally manage other important medical emergencies. Stroke is an important public health emergency with significant mortality and morbidity. Timely treatment of acute stroke is critical to prevent disability. The current expert consensus statement on behalf of the Indian Stroke Association outlines the issues and suggestions related to the management of stroke during this ongoing COVID-19 pandemic.

Mechanical device the Penumbra system in the management of acute stroke: report of five cases.

Use of mechanical devices in acute ischemic stroke has shown promise not only in recanalization rates but also with better clinical outcome and also extension of the window period to 8 hours. This is the first reported series of use of mechanical devices in India. We report five patients with acute stroke in whom mechanical devices (Penumbra System, Alameda, California) were used for thrombolysis. All the treated vessels (100%) were successfully re-canalized, Trials In Myocardial Infarction (TIMI) score of 3. At 90-day follow-up, of the 5 patients treated, 2 had modified Rankin score (mRS) of < 2. This small series shows the safety and efficacy of the Penumbra System in the thrombolysis of large vessel occlusive disease.

Intra-arterial thrombolysis in acute ischemic stroke: a single center experience.

Intra-arterial thrombolysis (IAT) is a treatment modality in patients with acute large vessel occlusive ischemic stroke. To our knowledge, this is probably the first reported study of intra-arterial thrombolysis in acute ischemic stroke from India. Of the 17 patients treated who recieved IAT, successful recanalization was achieved in nine patients, Thrombolysis in Myocardial Infarction (TIMI) score of 2 or 3. At 90-day follow-up, eight patients achieved modified Rankin Scale (mRS) score of < 2.
