The Role of Computational Fluid Dynamics in the Management of Unruptured Intracranial Aneurysms: A Clinicians' View
Objective. The
importance of hemodynamics in the
etiopathogenesis of intracranial aneurysms (IAs)
is widely accepted. Computational fluid dynamics
(CFD) is being used increasingly for hemodynamic
predictions. However, alogn with the continuing
development and validation of these
tools, it is imperative to collect
the opinion of the clinicians.
Methods. A workshop on CFD was
conducted during the European Society of
Minimally Invasive Neurological Therapy (ESMINT)
Teaching Course, Lisbon, Portugal.
36 delegates, mostly clinicians,
performed supervised CFD analysis for an IA, using the
@neuFuse software developed within the European
project @neurIST. Feedback on the workshop was
collected and analyzed. The
performance was assessed on a scale of 1 to 4
and, compared with experts' performance.
Results. Current dilemmas in
the management of unruptured IAs remained the
most important motivating factor to attend the
workshop and majority of participants showed interest in participating in a
multicentric trial. The participants achieved
an average score of 2.52 (range 0–4) which was 63% (range 0–100%) of an expert user. Conclusions.
Although participants showed a manifest interest
in CFD, there was a clear
lack of awareness concerning the role of
hemodynamics in the etiopathogenesis of IAs and
the use of CFD in this context. More efforts
therefore are required to enhance understanding of the
clinicians in the subject

Neurosurgery activity levels in the United Kingdom and republic of Ireland during the first wave of the covid-19 pandemic - a retrospective cross-sectional cohort study
The impact of Covid-19 on surgical patients worldwide has been substantial. In the United Kingdom (UK) and the Republic of Ireland (RoI), the first wave of the pandemic occurred in March 2020. The aims of this study were to: (1) evaluate the volume of neurosurgical operative activity levels, Covid-19 infection rate and mortality rate in April 2020 with a retrospective cross-sectional cohort study conducted across 16 UK and RoI neurosurgical centres, and (2) compare patient outcomes in a single institution in April-June 2020 with a comparative cohort in 2019. Across the UK and RoI, 818 patients were included. There were 594 emergency and 224 elective operations. The incidence rate of Covid-19 infection was 2.6% (21/818). The overall mortality rate in patients with a Covid-19 infection was 28.6% (6/21). In the single centre cohort analysis, an overall reduction in neurosurgical operative activity by 65% was observed between 2020 (n = 304) and 2019 (n = 868). The current and future impact on UK neurosurgical operative activity has implications for service delivery and neurosurgical training
