Comparing treatment outcomes of intracranial bifurcation aneurysms locations using the WEB device

The Woven EndoBridge (WEB) device has FDA approval for treatment of wide-necked intracranial bifurcation aneurysms. It has been shown to result in adequate occlusion in bifurcation aneurysms overall, but its usefulness in the individual bifurcation locations has been evaluated separately only in few case series, which were limited by small sample sizes.
In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, interviews Dr. Nimer Adeeb (1)and Dr. Adam Dmytriw (2) on their paper "Comparing treatment outcomes of various intracranial bifurcation aneurysms locations using the Woven EndoBridge (WEB) device".

Sex differences in endovascular thrombectomy outcomes in large vessel occlusion

Sex disparities in acute ischemic stroke outcomes are well reported with IV thrombolysis. Despite several studies, there is still a lack of consensus on whether endovascular thrombectomy (EVT) outcomes differ between men and women.
In this podcast, we discuss the Selection for Endovascular Treatment in Acute Ischemic Stroke (SELECT) study, in which women had similar discharge outcomes as men following EVT, in a propensity-matched cohort, but the improvement from discharge to 90 days was significantly worse in women, suggesting the influence of post-discharge factors.

ESO-ESMINT expedited recommendation on intravenous thrombolysis before mechanical thrombectomy

In the latest podcast, we discuss the joint expedited recommendations from the European Stroke Organisation (ESO) and the European Society for Minimally Invasive Neurological Therapy (ESMINT) on indication for intravenous thrombolysis before mechanical thrombectomy in patients with acute ischemic stroke and anterior circulation large vessel occlusion.
JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, interviews Dr. Guillaume Turc, Department of Neurology, GHU Paris Psychiatrie et Neurosciences, Université de Paris, and co-chair of the module working group.

Major complications of dural venous sinus stenting for idiopathic intracranial hypertension

Venous sinus stenting (VSS) is a safe, effective, and increasingly popular treatment option for selected patients with idiopathic intracranial hypertension (IIH). Serious complications associated with VSS are rarely reported.
In this podcast, JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Dr. Kyle Fargen, from the Department of Neurosurgery, Wake Forest University, Winston-Salem, North Carolina, about a case series in which serious complications after VSS were identified retrospectively from multicenter databases. The cases are reviewed and learning points regarding complication avoidance and management are presented in his paper (https://jnis.bmj.com/content/early/2021/04/27/neurintsurg-2021-017361).

COMPASS: intravenous ateplase and the efficacy of aspiration vs. stent retriever thrombectomy

In this podcast, we discuss the COMPASS: a trial of aspiration thrombectomy versus stent retriever thrombectomy as first-line approach for large vessel occlusion, comparing patients with and without prior intravenous (IV) alteplase administration.
JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Maxim Mokin, from the Department of Neurosurgery and Brain Repair, University of South Florida, Tampa, USA, about the post hoc analysis. which concludes that prior administration of IV alteplase may adversely affect the efficacy of aspiration, whilst it does not seem to influence the stent retriever first approach to MT in patients with anterior circulation ELVO.

Long-term angiographic follow-up following Pipeline embolization of intracranial aneurysms

Flow diversion of intracranial aneurysms with the Pipeline Embolization Device (PED) is commonly performed, but the value of long-term angiographic follow-up has not been rigorously evaluated. The study discussed in this podcast examines the prevalence of actionable findings of aneurysm recurrence and development of in-stent stenosis in a cohort of patients that underwent long-term angiographic follow-up at multiple time points.
JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews Dr Akash P. Kansagra, from the Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, USA.

Ophthalmic artery occlusion in intra-arterial chemotherapy for retinoblastoma

Retinoblastoma is the most common primary intraocular malignancy in children.
In this podcast, JNIS Editor-In-Chief Felipe C. Albuquerque and Pascal Jabbour discuss a study from July’s issue, concluding that local factors relating to the chemotherapy and selective microcatheterization of the ophthalmic artery are essential factors in the development of ophthalmic artery thrombosis, as seen by the association of ophthalmic artery thrombosis with the frequency of intra-arterial chemotherapy.
Dr Jabbour, Department of Neurological Surgery, Thomas Jefferson University, Philadelphia, USA, is the corresponding author of 'Incidence and predictors of ophthalmic artery occlusion in intra-arterial chemotherapy for retinoblastoma' - https://jnis.bmj.com/content/13/7/652

Complete flow control in transvenous embolization of cerebral arteriovenous malformations

In this podcast, JNIS Editor-In-Chief Felipe C. Albuquerque and Adnan Siddiqui discuss a case series that describes complete flow control using concurrent transient rapid ventricular pacing with afferent arterial balloon flow arrest technique as “safe and feasible” for transvenous embolization of select cerebral arteriovenous malformations (AVM).
Dr Siddiqui (Department of Neurosurgery, University at Buffalo, NY, USA) is the lead author of “Complete flow control using transient concurrent rapid ventricular pacing or intravenous adenosine and afferent arterial balloon occlusion during transvenous embolization of cerebral arteriovenous malformations: case series”, published in the April 2021 issue of JNIS.

COVID-19: the downtrend of African American stroke patients receiving mechanical thrombectomy

JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews Sami Al Kasab and Alejandro Spiotta, both from the Medical University of South Carolina, Charleston, USA. They discuss the Stroke Thrombectomy and Aneurysm Registry data showing an “alarming downtrend in mechanical thrombectomy rates in African American patients during the COVID-19 pandemic”.

Environmental sustainability in neurointerventional procedures

Operating rooms contribute between 20% to 70% of hospital waste. Neurointerventional procedures, in particular, generate a substantial amount of that waste: an average of 8 kg per case, recently aggravated by the COVID-19 pandemic.
