Background: It is unclear what factors clinicians consider when deciding about endovascular thrombectomy (EVT) in acute ischemic stroke patients with a pre-existing disability. We aimed to explore international practice patterns and preferences for EVT in patients with a pre-stroke disability, defined as a modified Rankin score (mRS) ≥ 2.Methods: Electronic survey link was sent to principal investigators of five major EVT trials and members of a professional interventional neurology society.Results: Of the 81 survey-responding clinicians, 57% were neuro-interventionalists and 33% were non-interventional stroke clinicians. Overall, 64.2% would never or almost never consider EVT for a patient with pre-stroke mRS of 4-5, and 49.3% would always or almost always offer EVT for a patient with pre-stroke mRS 2-3. Perceived benefit of EVT (89%) and severity of baseline disability (83.5%) were identified as the most important clinician-level and patient-level factors that influence EVT decisions in these patients.Conclusion: In this survey of 80 respondents, we found that EVT practice for patients with pre-stroke disability across the world is heterogenous and depends upon patient characteristics. Individual clinician opinions substantially alter EVT decisions in pre-stroke disabled patients.

Despite significant advances in the treatment and rehabilitation of stroke, level of post-stroke disability remains at a fairly high level. Recent innovative developments in the rehabilitation of these patients provide good results in terms of functional outcome. One of such developments is method of virtual reality (VR), which affects not only the speed and volume of regaining movement, as well as coordination, but also normalizes the psycho-emotional background, increasing the motivation of patients to improve the recovery process. This article provides a literature review of the use of the VR method in the rehabilitation of post-stroke patients, neurophysiological aspects of recovery of lost functions using this method are considered.

<b><i>Introduction:</i></b> The management and prognosis of acute ischemic stroke due to multiple large-vessel occlusion (LVO) (MLVO) are not well scrutinized. We therefore aimed to elucidate the differences in patient characteristics and prognosis of MLVO and single LVO (SLVO). <b><i>Methods:</i></b> The Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism Japan Registry 2 (RESCUE-Japan Registry 2) enrolled 2,420 consecutive patients with acute LVO who were admitted within 24 h of onset. We compared patient prognosis between MLVO and SLVO in the favorable outcome, defined as a modified Rankin Scale (mRS) score ≤2, and in mortality at 90 days by adjusting for confounders. Additionally, we stratified MLVO patients into tandem occlusion and different territories, according to the occlusion site information and also examined their characteristics. <b><i>Results:</i></b> Among the 2,399 patients registered, 124 (5.2%) had MLVO. Although there was no difference between the 2 groups in terms of hypertension as a risk factor, the mean arterial pressure on admission was significantly higher in MLVO (115 vs. 107 mm Hg, <i>p</i> = 0.004). MLVO in different territories was more likely to be cardioembolic (42.1 vs. 10.4%, <i>p</i> = 0.0002), while MLVO in tandem occlusion was more likely to be atherothrombotic (39.5 vs. 81.3%, <i>p</i> &#x3c; 0.0001). Among MLVO, tandem occlusion had a significantly longer onset-to-door time than different territories (200 vs. 95 min, <i>p</i> = 0.02); accordingly, the tissue plasminogen activator administration was significantly less in tandem occlusion (22.4 vs. 47.9%, <i>p</i> = 0.003). However, interestingly, the endovascular thrombectomy (EVT) was performed significantly more in tandem occlusion (63.2 vs. 41.7%; adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.1–5.0). The type of MLVO was the only and significant factor associated with EVT performance in multivariate analysis. The favorable outcomes were obtained less in MLVO than in SLVO (28.2 vs. 37.1%; aOR, 0.48; 95% CI, 0.30–0.76). The mortality rate was not significantly different between MLVO and SLVO (8.9 vs. 11.1%, <i>p</i> = 0.42). <b><i>Discussion/Conclusion:</i></b> The prognosis of MLVO was significantly worse than that of SLVO. In different territories, we might be able to consider more aggressive EVT interventions.

The Impact

Background: Targeted eloquence-based tissue reperfusion within the primary motor cortex may have differential effect on disability as compared to the traditional volume-based (TICI) reperfusion after endovascular thrombectomy (EVT) in setting of acute ischemic stroke (AIS). Methods: We explored the impact of eloquent reperfusion (ER) within primary motor cortex (PMC) on clinical outcome (mRS) in AIS patients undergoing EVT. ER was defined as presence of flow on final digital subtraction angiography (DSA) within four main cortical branches, supplying the PMC (MCA - precentral, central, anterior parietal; ACA- pericallosal) and graded as absent (0), partial (1), and complete (2). Prospectively collected data from two centers were analyzed. Multivariable analysis was conducted to assess the impact of ER on 90-day disability (mRS) among patients with anterior circulation occlusion who achieved partial reperfusion (TICI 2 a and b). Results: Among the 125 patients who met study criteria, median age was 73, median NIHSS was 16, median ASPECTS was 7, 48% (60/125) were female, and 36.8% achieved functional independence (mRS 0-2) at 90 days. ER distribution was: Absent (0) in 19/125 (15.2%); Partial (1) in 52/125 (41.6%), and Complete (2) in 54/125 (43.2%). TICI 2b was achieved in 102/125 (81.6%) and ER was substantially higher in those patients (p<0.001). In multivariate analysis, in addition to age and sICH, ER had a profound independent impact on 90-day disability (OR 6.10, p=0.001 for ER 1 vs 0; and OR 9.87, p<0.001 for ER 2 vs 0). In contrast, extent of total partial reperfusion (TICI 2b vs 2a) was not related to 90-day disability. Conclusions: Our findings support that eloquent PMC-tissue reperfusion is a major determinant of functional outcome, more impactful than volume-based degree of partial reperfusion. More aggressive, PMC-targeted revascularization among patients with non-eloquent partial reperfusion may further improve post-stroke disability after EVT.

Anticoagulant use, such as heparin, is usually contraindicated in acute stroke patients. We present a study of patients, who were treated with intravenous heparin after a stroke that were also found to have an intraluminal thrombus. Prior studies imply that recanalization is achieved with heparin; however heparin should only prevent thrombus propagation. Therefore it is unclear whether and how IV heparin can achieve recanalization of intraluminal thrombi in acute stroke patients. A retrospective review of all acute stroke patients from a single stroke center who received a therapeutic IV heparin infusion from 5/2006 to 9/2011 were included in the study. We compared patients who had complete/partial recanalization and/or improved flow versus those that did not, with both these groups on a standard intravenous heparin infusion protocol. Demographic data was compared between the groups. Average partial thromboplastin time (PTT) during heparin infusion, time between computed tomography angiographies (CTAs), time from stroke onset to receiving IV heparin, and vessel occluded were also compared between groups. Forty-one patients (19 female, 22 male) were included in the study with a total of 55 vessels (either carotid, middle cerebral artery, anterior cerebral artery, posterior cerebral artery/posterior circulation) having intraluminal thrombi; 31 patients had 41 vessels with either partial or complete recanalization of effected vessels, while 10 patients had 14 vessels that did not have at least one vessel recanalize while on heparin. Using t-test we noted that the average PTT between the vessels that had partial/complete recanalization group (61.74) and non-recanalization group (66.30) was not statistical significantly different (P=0.37).The average time in days on heparin between vascular imaging studies (CTA/conventional angiogram) in the group of vessels with partial/complete recanalization (7.12 days) and the ones with no change (6.11 days) was not significantly different between the two groups (P=0.59). Patient’s vessels receiving heparin for &lt;24 hours <em>versus</em> those &gt;24 hours did not significantly differ either (P=0.17). This study compares patient characteristics associated with recanalization of intraluminal thrombi in acute stroke patients on heparin. Recanalization of intraluminal thrombi are not associated with average PTT or duration on heparin.

Background: Few studies have shown the impact of substance use (SU) on treatment and outcomes of stroke patients. Research suggests stigma related to SU impacts patient experience in healthcare settings. In this study we assessed whether there were differences in patient characteristics and outcomes for stroke patients with SU compared to those with no substance use (NSU). Methods: Retrospective data from two Oregon hospitals included patients admitted with stroke diagnosis, 18 years or older, who discharged between October 2017 and May 2019. Patients with documented SU and specific SU type were compared to patients with NSU with regard to demographics, medical history, stroke subtypes, treatment, discharge disposition and length of stay (LOS). SU was defined as any documented abuse of alcohol (ETOH), methamphetamine (MA), cannabis, opiates, cocaine, benzodiazepines, and Methyl-enedioxy-methamphetamine (MDMA). Non parametric median tests and Pearson’s chi square tests were used. Results: Among 2,030 patients included in the analysis, 13.8% (n=280) were SU and 86.2% (n=1,750) were NSU. Patients with SU were significantly younger, median age (61 vs. 73, p <.001) and less were female (35.4% vs. 53.6%, p <0.001). Those with SU had lower prevalence of dyslipidemia (43.6% vs. 59.5%, p <0.001), AFIB (12.5% vs. 22.2%, p <0.001), and previous TIA (6.1% vs 10.8%, p=0.02), and more smoked (54.3% vs 13.3% p <0.001). More patients with SU arrived via transfer (38.4% vs 27.4%, p=.001). Fewer patients with SU expired or were discharged to hospice (8.9% vs 13.7%) and a greater percent left against medical advice (AMA) (3.2% vs 0.6%) (p<.001). When comparing specific SU types to NSU, all SU groups were younger, had similar medical histories and a greater proportion left AMA. Only MA users had differentiating stroke diagnoses with a higher percent of SAH (14.5% vs 5.6%) (p=.003) in addition to longer LOS (6 vs 4 days, p=.006). No differences were found in acute stroke treatment rates. Conclusion: Patients with SU were demographically different from the NSU population and did differentiate on some stroke care outcomes and processes, potentially indicating opportunities to address stigma around substance use to meet the needs of patients with both stroke and substance use.

Background and purpose: Modern stroke treatment has been revolutionized by image-guided selection of patients for endovascular thrombectomy. Current automated platforms allow for real-time identification of large vessel occlusion and salvageable brain tissue. We sought to evaluate the performance of these platforms with regard to identification of infarcted and salvageable tissue. Methods: We studied all patients that presented to Henry Ford Health System hospitals over a period of 6 weeks, received CT perfusion imaging of the brain upon initial presentation. The images were processed with two automated software platforms. We prospectively measured volumes of tissue with cerebral blood flow (CBF) < 30% of contralateral hemisphere, Tmax >6 secs, and hypoperfusion indices (defined as the ratio of volumes Tmax>10 secs and Tmax>6 secs). We compared the outputs of the two platforms and analyzed the performance of each platform. Results: 66 scans were included in our study. Both platforms were able to image all stroke patients within their FDA-approved indications. With regard to all scans, both platforms were noted to demonstrate comparable CBF<30% volumes (6.32 ml. vs 4.97 ml, p=0.276), and hypoperfusion indices (0.278 vs 0.338, p=0.344). However, there was statistically significant discrepancy in the volumes of tissue with Tmax>6 secs (23.96 vs 14.18 ml, p=0.023). Analysis of a subset of 12 scans, with evidence of LVO or severe symptomatic stenosis on corresponding CTA, showed again comparable CBF<30% volumes (12.84 ml vs 13.67 ml, p=0.725), and hypoperfusion indices (0.344 vs 0.314, p=0.699). However, the Tmax>6 secs volume discrepancy was greater and still statistically significant (75.54 ml vs 39.58 ml, p=0.048) Conclusions: Automated software platforms are an invaluable aid in the identification of salvageable tissue, and selection of patients for endovascular thrombectomy in the 6-24 hour window. However, the substantial difference in the identified volumes of hypoperfused tissue-at-risk may result in largely different clinical decisions and patient outcomes. Further validation efforts (and harmonization of algorithms) are required. Stroke teams should be aware of the limitations of automated analysis and need for expert review.

BackgroundIntrathecal baclofen (ITB) is a useful treatment for hypertonia where non-invasive treatments have been ineffective or poorly tolerated. There is an absence of national guidance on selection criteria and a lack of literature regarding patient characteristics and treatment details for children and young people (CYP) receiving ITB therapy in the UK and Ireland. We aimed to gather patient and treatment characteristics for CYP receiving ITB in the UK and Ireland.MethodsAn electronic survey was sent to all paediatric ITB centres in the UK and Ireland. Anonymised data were returned between December 2019 and April 2020. CYP >16 years and those awaiting ITB pump removal were excluded from the dataset.Results176 CYP were identified as receiving ITB therapy across the UK and Ireland. The majority of CYP with ITB pumps were non-ambulant (93%) with a diagnosis of cerebral palsy (79%). Median age of ITB insertion was 9 years; median current age was 14 years. 79% of CYP had significant spasticity, 55% had significant dystonia. The most commonly used ITB dosing modes were continuous (73%) and flexible (23%).ConclusionsITB pumps were most frequently used for non-ambulant CYP with cerebral palsy and existence of spasticity and/or dystonia in the UK and Ireland. Most CYP were receiving a continuous dose of ITB. There is significant variation in the number of paediatric ITB pumps across UK and Ireland. There is a need for development of nationally accepted paediatric referral criteria and clinical standards for ITB use.

Abstract Background Rhinitis medicamentosa is a non-allergic form of rhinitis that is typically caused by prolonged use of topical nasal decongestants. This condition commonly affects young adults and treatment is not trivial. We aimed to survey Canadian Otolaryngologists to determine practice patterns and their opinions regarding this under-studied condition. Methods An electronic survey was sent to practicing Otolaryngologists within the Canadian Society of Otolaryngology – Head and Neck Surgery. The survey contained 16 questions pertaining to the diagnosis and treatment of rhinitis medicamentosa, as well as opinions on public and primary care awareness of proper use of nasal decongestants. Results The survey was distributed to 533 Otolaryngologists and 69 surveys were returned (response rate of 13%). Cessation and weaning of decongestant (96%), and intranasal steroids (94%) were the most common methods for treating RM. Intranasal saline rinses (55%) and oral steroids (25%) were also supported by some respondents. For those who recommended cessation/weaning, 61% also concurrently introduced an intranasal steroid during this process. The majority responded that current warnings on nasal decongestants were inadequate (75%), and were not visible enough (79%). Conclusions Rhinitis medicamentosa is a common, and very preventable condition. Although the literature lacks a standardized approach to RM, our survey has shown that many Otolaryngologists diagnose and treat RM in a similar manner. Treatment tends to focus on decongestant cessation, often with concurrent introduction of intranasal steroids. It was felt the warning labels on the topical medications are not currently satisfactory.
