Combined delivery catheters vs. traditional aspiration in stroke thrombectomy
Optimising mechanical thrombectomy speed and efficiency remains a primary focus in acute ischemic stroke management. In this episode, JNIS Editor, Dr. Michael Chen, talks with Dr. Keiko Fukuda, a neurointerventional fellow at UCLA and practising neurointerventionalist in Monterey, California, and Dr. Victor Szeder, Professor of Radiology, Neurology, and Neurosurgery and Director of the Neurointerv
Endovascular shunting for normal pressure hydrocephalus: safety trial insights with Professor Adel Malek

In this episode, JNIS Editor, Dr. Michael Chen, talks with corresponding author Professor Adel Malek (Tufts Medical Center, Boston) (1) to discuss h
Reperfusion grade and outcomes in the ESCAPE-MeVO Trial
Achieving near-complete reperfusion in medium vessel occlusions (MeVO) is linked to smaller final infarct volumes. However, this did not translate into a statistically significant shift in 90-day functional independence.
In this episode, JNIS Editor-in-Chief, Dr. Michael Chen, and Professor Johanna Ospel (1) discuss the post-hoc analysis of the ESCAPE-MeVO trial, titled "Reperfusion grade and
Reducing opioid use after aneurysmal subarachnoid hemorrhage: the role of MMA infusion

The author describes the underlying
Unseen wounds: the psychological toll of complications
Medical professionals can oftentimes fall under the category of "second victims", as they experience burnout and moral injury from the impacts of their work. Over the course of a neurointerventionalist's medical career, serious complications in procedures are sadly inevitable. These can be difficult to process, and there are not always the systems in place to provide the support needed, either ins

Non-invasive imaging for pulsatile tinnitus: a diagnostic algorithm
Pulsatile tinnitus — the perception of a rhythmic sound in sync with the heartbeat — can be a key indicator of underlying vascular or structural pathology. In this episode, JNIS new Editor-in-Chief Dr. Michael Chen speaks with Dr. Madhavi Duvvuri and Dr. Matthew Robert Amans, authors of Non-invasive imaging modalities for diagnosing pulsatile tinnitus: a comprehensive review and recommended imagin
Long-term clinical outcomes of the SCENT trial
In the SCENT trial, researchers investigated the effects of the Surpass flow diverter system for treating wide-necked aneurysms. Five-year results of this trial have recently been published in JNIS, presenting the safety and effectiveness outcomes of treatment with the Surpass Streamline flow diverter system. The study analyses the rates of aneurysm occlusion and adverse events.

Evaluating socioeconomic influences on aneurysm treatment with the Area Deprivation Index
High risk factors for stroke such as smoking and blood pressure are not equally represented throughout the patient population. These are just two of the socioeconomic influences on cerebrovascular disease. One way to view this association is through the lens of the Area Deprivation Index (ADI), a measure of neighbourhood-level deprivation, and this was the approach of the study discussed in this e
The River study: a novel venous sinus stent for the treatment of idiopathic intracranial hypertension
The "River" stent is a novel stent designed specifically to account for the anatomical and procedural requirements of venous sinus stenosis. A multicentre study of the device's safety and efficacy is underway, comprising 39 subjects across 5 US centres. The 1-year results have been recently published in JNIS. Editor-in-Chief of JNIS, Dr. Felipe C. Albuquerque, interviews Dr. Athos Patsalides¹, aut
Impacts of prolonged intracranial catheter dwell time
Observations from practice and data analysis have shown that the duration of mechanical thrombectomy procedures are a strong predictor of outcome even with successful procedures. A large multicenter study was conducted which gives insight into choices between catheter types, and strategic decisions to be made during prolonged procedures.
Dr Felipe C. Albuquerque, Editor-in-Chief of JNIS, interview
Reviewing dual anti-platelet therapy durations after stent-assisted coiling
The use of assistive devices when treating unruptured aneurysms is widespread in neurointerventional practice. But there is no standard for how long patients should receive dual anti-platelet therapy after the procedure, to protect them from thrombotic complications. Durations can range from one month to one year. This episode looks at a review of patient data across 12 locations to understand the
National trends in catheter angiography and cerebrovascular imaging
There has been a large increase in the number of non-invasive neurovascular studies performed in the last decade, particularly CT angiograms and MR angiograms. What has this meant for catheter-based angiography? This episode looks at an analysis done on a large claims database in the USA, to observe trends in imaging modalities, as well as the distinctions in use by neurosurgeons and radiologists.
Malpractice claims and complaints in Neurointervention
Although many U.S. neurointerventionalists report at least one stressful malpractice claim over their career, the majority conclude without any court proceedings or direct repercussions in their practice. In this podcast, we look at the prevalence and causes of malpractice claims and complaints filed with state medical boards against neurointerventionalists, and some of the risk factors in an incr
