O-006 Influence of geolocational factors on patient outcomes post EVT: a population based analysis of transport over long distances in the province of Saskatchewan
ConclusionsReal world geographic factors influence time to treatment, however patient specific factors play a great role in determining patient’s overall outcome during long transports. Factors such as collaterals, occlusion location, and initial aspects are more important than number of kilometers distance travelled or transfer from PSC alone. In an efficient transport system, centralized treatment at the CSC is a viable solution and does not preclude achieving functionally independent outcomes.Abstract O-006 Figure 1Disclosures N.

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...

Acute ischaemic stroke associated with SARS-CoV-2 infection in North America
Conclusion There is relationship between COVID-19-associated AIS and severe disability or death. We identified several factors which predict worse outcomes, and these outcomes were more frequent compared to global averages. We found that elevated neutrophil-to-lymphocyte ratio, rather than D-Dimer, predicted both morbidity and mortality.

Three-month functional outcomes following endovascular thrombectomy during the first wave of the COVID-19 pandemic: a Canadian single-center cohort study
Conclusion In this single-center cohort study conducted in a Canadian pandemic epicenter, the first 6 months of the COVID-19 pandemic did not impact 90-day functional outcomes or death among EVT-treated patients.

Characteristics and career outcomes of Neurosurgery Research and Education Foundation research fellowship recipients.
CONCLUSIONSThe majority of AANS/NREF research award recipients enter academics as fellowship-trained neurosurgeons, with approximately one-third obtaining NIH funding. Analysis of this unique cohort allows for identification of characteristics of academic success. PMID: 30738408 [PubMed - as supplied by publisher]

Risk of intracranial hemorrhage after carotid artery stenting versus endarterectomy: a population-based study.
CONCLUSIONS CAS is associated with a rare but higher risk of ICH relative to CEA. Future research is needed to devise strategies that minimize the risk of this serious complication after carotid artery revascularization. PMID: 29393758 [PubMed - as supplied by publisher]
