Venous congestive myelopathy (VCM) often results from impaired venous outflow secondary to a spinal arteriovenous malformation.1,2 Foix-Alajouanine syndrome, also known as subacute necrotizing myelopathy or angiodysgenetic necrotizing myelopathy, is the term formerly used to describe this progressive myelopathy. One of the causes is known to be spinal dural arteriovenous fistula (SDAVF).3

Interventional Neuroradiology
This year, Interventional Neuroradiology will be published in the traditional printed hard copy format and also in a digital edition available on the Internet. This move will allow our readers to exploit the myriad opportunities digital medium has to offer, especially for a journal with an international readership. The subscription price will be lower in view of cost savings resulting from the digital format. The digital subscription will offer readers the leaf through format on-line, the PDF to download and print, and bibliography search with access to a dynamic articles archive. We are convinced that the digital format will further … Continue reading >>

We commend Cuvinciuc et al1 on their recent review of nontraumatic cortical subarachnoid hemorrhage (cSAH). While not an uncommon clinical presentation, there is an overall paucity of literature on this subject, with the … Continue reading >>
Interventional Neuroradiology: Now in MEDLINE
Most of you know that last year AJNR entered a cooperative agreement with Interventional Neuroradiology (IN). Since AJNR accepts very few case reports and technical notes, we encourage the authors of these types of articles to send them to our “sister” journal, IN. Many prospective authors can rest assured that their articles will be thoroughly and fairly evaluated by Dr. Karel terBrugge and his editorial team. Through the efforts of Dr. Marco Leonardi who publishes IN the journal is now indexed in MEDLINE making it more important, relevant, and useful. IN is now in its 15th year of publication and … Continue reading >>
High Rate of Serious Complications with Stent-Assisted Coiling in Unruptured Intracranial Aneurysms: Lessons to Learn
This post was written by Dr. Willem Jan van Rooij.
Re: Piotin M, Blanc R, Spelle L, Mounayer C, Piantino R, Schmidt PJ, Moret J. Stent-Assisted Coiling of Intracranial Aneurysms. Clinical and Angiographic Results in 216 Consecutive Aneurysms.

An intracranial stent is a powerful tool to assist in the endovascular treatment of wide necked and fusiform aneurysms. However, some disadvantages exist. First, the prolonged antiplatelet medication that is needed to prevent in-stent thrombosis may be a source of complications, especially in recently ruptured aneurysms. Second, the placement of the
CT-Guided Cervical Nerve Root Blocks
I have three questions for radiologists who perform spinal injections for pain management.
1. How many people regularly do cervical nerve root blocks?
2. Are you using CT or conventional fluoro?
3. If you are using CT, do you use contrast to confirm needle position?
It would be great for people to comment on the blog, but you can also email me directly.
Thanks!

About : Long-Term Follow-Up of 1036 Cerebral Aneurysms Treated by Bare Coils: A Multicentric Cohort Treated between 1998 and 2003
This article references:
Gallas S, Januel AC, Pasco A, et al. Long-Temr Follow-Up of 1036 Cerebral Aneurysms Treated by Bare Colis: A Multicentric Cohort Treated between 1998 and 2003. AJNR Am J Neuroradiol first published on August 13, 2009 as doi: 10.3174/ajnr.A1744.
The authors analyzed the long-term stability of treatment of cerebral aneurysms treated exclusively with GDC, focusing in re-treatments and re-bleeding rates during follow up.
The authors have been meticulous in data recollection, once, these patients have been followed since 1998. Additionally, the fact to be a multicentric trial, demands a greater author commitment for the patients follow … Continue reading >>
Does the Insurance Company Require the Certification of Neurointerventionist for Payment of the Interventional Procedure?
Does the insurance company require the certification of neurointerventionist for payment of the interventional procedure?
I’m an interventional neuroradiologist in South Korea. Korea’s health insurance service inquired of the Korean Society of Interventional Neuroradiology what is the qualification of neurointerventionist for payment of interventional procedure.
I want to know certification requirements for neurointervention in America.
Does the insurance company require the other certification as well as ABR or institutional certification of fellowship?… Continue reading >>
Mass in Septum Pellucidum
Does anyone know what this mass could be? It was biopsied 2 years ago and pathology reported it as “normal brain tissue”.
As you can see, the lesion is hyperintense on T2, hypointense on T1 and does not enhance. No calcifications are present and no there is no restricted diffusion .
The patient is 25 year old and has loss of short term memory and seizures.
Any input into the nature of the mass is welcome.… Continue reading >>

Pediatric contraindication for Onyx?
Package inserts for the Echelon, Marathon, and UltraFlow microcatheters from EV3 note that these devices are specifically “contraindicated for neonatal and pediatric use”. Since these microcatheters are needed to inject Onyx, these contraindications indicate that use of Onyx is not possible in neonatal or pediatric cases without violating this contraindication. Interestingly, the Onyx package insert does not state the same pediatric contraindication for Onyx itself. The microcatheter contraindications likely stem from bureaucratic regulatory processes, and, in fact, there is probably no evidence of any added risks specific to children. But if there ever was a complication in a pediatric case … Continue reading >>
