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.

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.

Field triage for endovascular stroke therapy
In a densely populated setting, for patients with stroke who are endovascular therapy candidates and closest to a primary stroke center from the field, triage to a slightly more distant comprehensive stroke center is associated with faster time to endovascular therapy, no delay to alteplase, and less disability at 90 days. Felipe de Albuquerque talks to Mahesh Jayaraman and Ryan McTaggart (Department of Diagnostic Imaging, Warren Alpert Medical School of Brown University, Rhode Island, USA) about their paper “Field triage for endovascular stroke therapy: a population-based comparison”, which is part of the March issue of JNIS and can be read for free on the journal's website: https://jnis.bmj.com/content/12/3/233.

M2 occlusions patients may benefit from endovascular therapy
M2 occlusions can present with serious neurological deficits, resulting in large infarcts and significant morbidity and mortality. The paper discussed in this podcast concludes that patients with M2 occlusions and higher baseline deficits (NIHSS score ≥9) may benefit from endovascular therapy, thus potentially expanding the category of acute ischemic strokes amenable to intervention. Listen to the conversation between the Editor-in-Chief of JNIS, Felipe de Albuquerque, and Ansaar Rai (Department of Interventional Neuroradiology, West Virginia University Hospital, USA), who is the co-author of “A population-based incidence of M2 strokes indicates potential expansion of large vessel occlusions amenable to endovascular therapy”.

Favorable revascularization therapy in patient with ASPECTS ≤5 in anterior circulation infarct
A low baseline Alberta Stroke Programme Early CT Score (ASPECTS) is strongly associated with low rates of favorable outcome in patients with acute stroke. The study discussed in this podcast evaluated the efficacy and safety of revascularization therapy in patient with ASPECTS ≤5 in anterior circulation infarct, concluding that revascularization therapy contributed to a favorable clinical outcome at 90 days, especially in patients younger than 70 years. The Editor-in-Chief of JNIS Felipe Albuquerque is joined by Vincent Costalat (Department of Neuroradiology, CHRU Gui de Chauliac, Montpellier, France), who co-authored the paper: "Favorable revascularization therapy in patients with ASPECTS ≤ 5 on DWI in anterior circulation stroke".

Flat detector derived parenchymal blood volume maps to estimate cerebral blood volume
Newer flat panel angiographic detector (FD) systems have the capability to generate parenchymal blood volume (PBV) maps. The ability to generate these maps in the angiographic suite has the potential to markedly expedite the triage and treatment of patients with acute ischemic stroke. David Fiorella, Department of Neurological Surgery, Stony Brook University Medical Center, NY, and colleagues, have compared FP-PBV maps with cerebral blood volume (CBV) maps derived using standard dynamic CT perfusion (CTP) in a population of patients with stroke.Rob Tarr asks him what they found.Read the full paper: http://jnis.bmj.com/content/6/6/451.full
