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.

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. [ABSTRACT FROM AUTHOR]

Introduction/Aims: Studies conducted during the coronavirus disease 2019 (COVID 19) pandemic have reported varied data regarding the incidence of Guillain--Barre syndrome (GBS). The present study investigated demographic and clinical features, management, and outcomes of patients with GBS during a specified period of the COVID 19 pandemic, and compared these features to those of GBS in the previous year. Methods: A multicenter, ambispective cohort study including 26 centers across India was conducted. Data from a pre COVID 19 period (March 1 to August 31, 2019) were collected retrospectively and collected ambispectively for a specified COVID 19 period (March 1 to August 31, 2020). The study was registered with the Clinical Trial Registry India (CTRI/2020/11/029143). Results: Data from 555 patients were included for analysis: pre COVID 19 (n = 334) and COVID 19 (n = 221). Males were more commonly affected during both periods (male:female, 2:1). Gastroenteritis was the most frequent antecedent event in 2019 (17.4%), whereas fever was the most common event in 2020 (10.7%). Paraparesis (21.3% versus [vs.] 9.3%, P = 0.001) and sensory involvement (51.1% vs. 41.3%; P = 0.023) were more common during COVID 19 in 2020, whereas back pain (26.3% vs. 18.4%; P = 0.032) and bowel symptoms (20.7% vs. 13.7%; P = 0.024) were more frequent in the pre COVID period. There was no difference in clinical outcomes between the two groups in terms of GBS disability score at discharge and 3 months after discharge. Independent predictors of disability in the pre COVID period included areflexia/hyporeflexia, the requirementfor intubation, and time to bulbar weakness; in the COVID 19 period, independent predictors included time from onset to admission, intubation, and intubation requirement. The mortality rate was 2.3% during the entire study period (13/555 cases). Discussion: Results of this study revealed an overall reduction in the frequency of GBS during the pandemic. The lockdown likely reduced the risk for antecedent infections due to social distancing and improved hygiene, which may have resulted in the reduction of the frequency of GBS. [ABSTRACT FROM AUTHOR]
