    John J Connors

    J. J. (Buddy) Connors MD, Interventional Neuroradiology, Vanderbilt University Medical Center, Nashville, TN.

    Re: Understanding IMS III: old data shed new light on a futile trial

    I read this article with great interest. The issue of tPA and its risk/benefit ratio for intra-arterial treatment of acute ischemic stroke is essential to understanding the results of IMS III. While possible toxic effects of...

  • Reply to: ADAPT FAST study: a direct aspiration first pass technique for acute stroke thrombectomy by Turk et al. Corrections of reported values of the STAR study.
    Vitor Mendes Pereira

    We read with interest the study published ADAPT FAST study article (Turk AS, et al.) as published first online in the Journal of NeuroInterventional Surgery on 25Feb2014. We would like to congratulate the authors for their work in improving aspiration technique for acute stroke treatment that have been quite disappointing on demonstrating improvement on clinical outcomes on previous publications (1, 2). The advent on th...

  • Carotid artery stenting without post-stenting balloon dilatation
    David M. Pelz

    Re: Ogata A et al. Carotid artery stenting without post-stenting balloon dilatation. J NeuroIntervent Surg 2013; Dec 6: (Epub ahead of print)

    We read with interest this article regarding carotid stenting (CAS) without post-stent balloon angioplasty. The authors believe that this method reduces the risk of embolic complications. They point out that every passage of a device across a carotid stenosis can generate...

  • Dissecting or dolichoectatic aneurysm?
    Paulo Puglia Jr

    To the editor,

    The interesting paper by Li et al. reports an important series of cases treated appropriately and carefully followed-up, but unfortunately the diagnosis may not be correct in all cases. Fusiform aneurysms appearing in angiograms may represent a variety of different histopathological pictures, including dissection, but also other types of aneurysms. A light to this question, quite recurrent in my p...

    Lee-Anne Slater

    Dear Dr. Tarr,

    We read with interest the recent editorial by Fiorella et al., entitled "Should Neurointerventional fellowship training be suspended indefinitely?", detailing the potential hazards of neurointerventional (NI) overtraining in the United States (US).1 We face similar issues in Australia pertaining to our own current NI workforce demand and NI trainee employment outlook.

    The landmass of Aus...

  • Re:The Influence of Angioarchitecture on Management of Pediatric Intracranial Arteriovenous Malformations
    Darren B. Orbach

    We read with interest Dr. Ding's response to our manuscript, "Angioarchitectural features associated with hemorrhagic presentation in pediatric cerebral arteriovenous malformations," and we thank him for his gracious comments. In response to his question regarding whether brain AVM angioarchitecture influences our particular treatment strategy, we would point out that the overwhelming majority of our pediatric patients wi...

  • The Influence of Angioarchitecture on Management of Pediatric Intracranial Arteriovenous Malformations
    Dale Ding

    I have read, with great interest, the paper by Ellis et al. titled 'Angioarchitectural features associated with hemorrhagic presentation in pediatric cerebral arteriovenous malformations [1]. The authors retrospectively reviewed the angiographic features of 135 pediatric patients, mean age 10.1 years (range 0-19 years), who were referred to Hospital for Sick Children in Toronto, Canada and Boston Children's Hospital ove...

  • The Impact of Endovascular Onyx Embolization on Acutely Ruptured Intracranial Arteriovenous Malformations
    Dale Ding

    I have read, with great interest, the paper by Stemer et al. titled 'Acute embolization of ruptured brain arteriovenous malformations' [1]. The authors describe a cohort of 21 patients with ruptured intracranial arteriovenous malformations (AVM) who were treated with endovascular Onyx (ev3, Irvine, California, USA) embolization in the acute phase following hemorrhage. The median interval from hemorrhagic presentation to...

  • Drive on
    David A. Rubin

    I am glad to see that my letter has piqued the interest of interventional neuroradiologists like Dr. Jagadeesan. I agree with him that no one should be running a fellowship that does not have the volume to expose trainees to enough cases so that they may obtain the necessary experience to practice safely. However, I think he has misunderstood my point. As I stated about the original piece, "I have no objection to the lo...

  • CT Perfusion or Time Criteria for Endovascular Stroke Management?
    Pascal Jabbour

    Nohra Chalouhi M.D., Stavropoula Tjoumakaris M.D.,and Pascal Jabbour M.D.

    We read with great interest the article by Turk et al[1] assessing the safety and efficacy of endovascular stroke intervention based on CT perfusion (CTP) criteria. The authors are to be congratulated for this excellent report and for achieving remarkably high rates of favorable outcomes (42%) in stroke patients with poor neurological sta...
