Posterior cranial fossa arteriovenous malformations are more prone to feeder vessel aneurysms

In this podcast, the Editor-in-Chief of JNIS, Robert Tarr, is joined by Ali Alaraj, the corresponding author of the study, "Increased prevalence and rupture status of feeder vessel aneurysms in posterior fossa arteriovenous malformations".
Dr Alaraj, from the Department of Neurosurgery, Neuropsychiatric Institute University of Illinois, Chicago, USA, explains why are posterior cranial fossa arteriovenous malformations (AVMs) more prone to developing associated aneurysms, specifically feeder vessel aneurysms. Feeder vessel aneurysms are more likely to be the source of hemorrhage in the posterior fossa. As such, they may be the most appropriate targets for initial and prompt control by embolization or surgery due to their elevated threat.

The low-profile visualized intraluminal support device use on wide-necked intracranial aneurysms

In this podcast, the Editor-in-Chief of JNIS, Robert Tarr, is joined by David Fiorella, the corresponding author of the study, "Final results of the US humanitarian device exemption study of the low-profile visualized intraluminal support (LVIS) device".
Dr Fiorella, from the Department of Neurological Surgery, Stony Brook University Medical Center, New York, concludes that the LVIS device facilitates coil embolization of wide-necked intracranial aneurysms with high rates of technical success. The process also granted an excellent safety profile, and very high rates of complete and near-complete occlusion at follow-up.

GRAFT reduces potential flow diverter malapposition and occasional acute thrombus formation

In this podcast, Dr Robert Tarr interviews Dr Matthew Gounis and Dr Ajit Puri on their latest study, "Grading of Regional Apposition after Flow-Diverter Treatment (GRAFT): a comparative evaluation of VasoCT and intravascular OCT".
GRAFT is a semi-automated image post-processing software, which uses intuitive two-dimensional representations of wall apposition from either high-resolution contrast-enhanced cone-beam CT (VasoCT) or intravascular optical coherence tomography (OCT) images.
The technique brings great prospects of reducing stroke-related complications when treating intracranial aneurysms. It delivers quantitative and visually convenient representations of potential flow diverter malapposition and occasional acute thrombus formation.

Three-dimensional printing of anatomically accurate patient specific intracranial aneurysm models

In this podcast, the Editor of JNIS, Robert Tarr, talks to Christof Karmonik, from the Houston Methodist Research Institute, USA, about the details of the study "Three-dimensional printing of anatomically accurate patient specific intracranial aneurysm models".
The research concluded that the 3D printed aneurysm models were accurate and able to be produced inhouse. Read the full paper here: http://jnis.bmj.com/content/early/2015/04/10/neurintsurg-2015-011686.full

Stroke treated with mechanical thrombectomy: outcomes of prior use of intravenous thrombolysis

With multiple RCTs demonstrating clear benefit of mechanical thrombectomy in ELVO, the question of best approach to patients eligible for simultaneous treatment with IV TPA and mechanical thrombectomy has been debated. Dr. Hirsch interviews Drs. Leslie-Mazwi and Weber after their instructive papers on this topic.
