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.
JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews Pey Ling Shum, Monash Health, Clayton, Victoria, Australia, about her recent paper “Environmental sustainability in neurointerventional procedures: a waste audit” - https://jnis.bmj.com/content/12/11/1053

Being a female physician in a male-dominated speciality

Sexism is common place in one of the most male-dominated subspecialties in medicine. Despite this, the prevalence of women physicians in neurointervention is steadily rising.
In this podcast, JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews neurointerventionalists Stephanie H Chen - Department of Neurological Surgery, University of Miami School of Medicine - and Marie-Christine Brunet - Department of Neurological Surgery (NEUR) at McGill University - about the challenges of being a female physician in this field.
They are the authors of the first study examining the amount of maternal and fetal radiation exposure during a pregnant neurointerventional fellow’s training. Spoiler alert: the findings suggest that, when optimal radiation safety practices are implemented, the fetal dose of a pregnant neurointerventionalist is negligible.

Transarterial and transvenous access in neurointervention

The recommendations resulting from the report of the SNIS Standards and Guidelines Committee on transarterial access are discussed in this podcast.
JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews Robert Starke (University of Miami MILLER School of Medicine, Miami Beach, Florida, and Westchester Medical Center, Valhalla, New York) and Justin Fraser (University of Kentucky, Lexington), who recently published the paper “Transarterial and transvenous access for neurointerventional surgery: report of the SNIS Standards and Guidelines Committee” on behalf of the Society of NeuroInterventional Surgery.

‘Chronic intracranial venous hypertension syndrome’: a new classification scheme for IIH

JNIS Editor-In-Chief Felipe C. Albuquerque discusses idiopathic intracranial hypertension (IIH) and a new patient classification paradigm with Kyle Fargen (Neurological Surgery, Wake Forest University, Winston-Salem, USA) and Michael Levitt (Neurological Surgery, University of Washington, Seattle, USA). Both authors recently wrote about the intersection between IIH and venous sinus stenosis, an increasingly hot topic within the neurointerventional community. In the podcast, the participants discuss this novel classification, venous sinus stenting, and issues pertaining to this diverse patient population.
