Consider alternative causes before allocating acute ischaemic stroke to COVID-19
We read with interest the excellent article by Dmytriw et al reported on a retrospective, multicenter cohort study of patients with COVID-19 with acute ischaemic stroke (AIS) admitted to stroke units in the USA and Canada between March and August 2020.1 The primary endpoint was a modified Rankin Scale (mRS) of 5–6 and the secondary endpoints were an mRS<3, ordinal RS, symptomatic intracerebral haemorrhage and complications during hospitalisation.1 It has been established that there may be an association between COVID-19-associated AIS and severe outcome or death, and that the neutrophil to lymphocyte ratio predict...

O13 School of thrombectomy - a 3-step approach to perform acute stroke treatment with simulator training and virtual supervision by remote streaming support (RESS)
ConclusionsThe 3-step approach increases the level of safety, as reported by the trainees and supervisor in this study, and may enable an accelerated training of neurointerventionalists.ReferencesKreiser K, Ströber L, Gehling KG, Schneider F, Kohlbecher S, Schulz CM, et al.

P53 ESMINT/EYMINT E-fellowship - experiences from two seasons and implications for future neurointerventional tele-observerships
ConclusionsTele-observerships may facilitate location-independent training of complex neurointerventional procedures through high levels of situational awareness. Future programs will have to incorporate individual training schedules to enable fellows to better attend complex elective procedures.ReferencesBechstein M, Elsheikh S, Wodarg F, et al.

Prevention of neurological complications during COVID-19: a retrospective analysis of the ISARIC4C national cohort
This study is the first to focus on the prevention of neurological complications and strongly supports the continued use of both dexamethasone and remdesivir in severe COVID-19. Our results suggest that the established benefit of dexamethasone on mortality in COVID-19 is not associated with an increased burden of long-term neurological disability.

200 Covid-19 and acute ischaemic strokes in CADASIL: a systematic review of the literature
Conclusions This systematic review describes the pattern of COVID-19 associated AIS in CADASIL. Such multiple infarcts, primarily affecting the internal borderzones, have been described in patients with Covid-19 without CADASIL. We discuss possible pathophysiological mechanisms, which may be extrapolated to patients with cerebral small vessel disease, including endothelial injury causing microvascular thrombosis and hypoperfusion due to cerebral blood flow dysautoregulation.

Cerebral venous thrombosis after COVID-19 vaccination: the role for endovascular treatment
Cerebral venous thrombosis (CVT) is a unique cause of stroke. Population-based studies demonstrate an incidence of clinically significant CVT of 1.3–1.5 per 100 000 per year.1 2 This may be an underestimated incidence, as these studies were not based on review of imaging and the often benign nature of this entity may lead to underdiagnoses. In the JNIS paper published by Cleaver et al,3 the authors describe their experience with endovascular treatment (EVT) in patients with cerebral venous sinus thrombosis in patients following COVID-19 vaccination. CVT-related stroke primarily affects young adult and middle-aged pat...

Inpatient virtual shared medical appointments to improve health literacy, increase patient self-efficacy, and reduce provider burnout in acute cerebrovascular pathology patients and their caregivers: a pilot study
CONCLUSIONS: Implementation of a vSMA program at a tertiary care center during a pandemic was feasible. Themes caregivers expressed on the postsession survey included better understanding of caring for a stroke patient and coping with the unpredictability of a patient's prognosis. The pandemic has precipitated shifts toward telehealth, but this study highlights the importance of avoiding marginalization of elderly and less technologically inclined populations.PMID:35921191 | DOI:10.3171/2022.4.FOCUS21764
