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 >>
Aunt Mickey (They Look the Same until You Undress Them). Cavernous Sinus Tumor or Something Else?
A young male presented with progressive right sided cranial nerve palsies was diagnosed as having a cavernous sinus syndrome. CT was done (Fig. 1) and showed a mass in the right cavernous sinus extending to the sphenoid sinus. Note that the mass contained some flecks of calcium and remodeled adjacent bones. At this point in time, the differential diagnosis included mainly a solid tumor (schwannoma, neurofibroma, meningioma, metastases [less like due to age and absence of primary tumor), lymphoma, and hemangioma). MR imaging with contrast was obtained and a coronal T1 image (Fig. 2) demonstrated that the mass enhanced homogeneously … Continue reading >>

The softness of endovascular coils enables the packing of an intracranial aneurysm at a higher density so complete embolization is possible. While softness is an important concept, it is rarely discussed in a quantitative fashion. This information is often regarded as proprietary by manufacturers and is not available to the public. Thus, we do not know what makes a coil soft and what makes … Continue reading >>
A Second-Generation, Endoluminal, Flow-Disrupting Device for Treatment of Saccular Aneurysms

Flow diversion stents and endoluminal flow-disrupting devices are new therapeutic approaches to treat challenging intracranial aneurysms [1,2]. The first generation Pipeline Embolization Device (PED) has already been used in clinical practice. The reported results of PED treatment of intracranial aneurysms appear to be promising and very encouraging for the neuro-endovascular field [1,2]. However, there has always been a lingering concern associated with … Continue reading >>
Willinsky RA et al, Clinical and Endovascular Follow-Up of Embolized Aneurysms
A recent article published by Dr Robert Willinsky and colleagues from Toronto is noteworthy and an excellent addition to the literature on the subject of endovascular treatment of ruptured aneurysms. This is one of the largest series on this subject and addresses, amongst other things, the important issue of rebleeding after endovascular repair.
In this large series, the rehemorrhage rate after embolization was 2.1%. The risk of rebleeding was 1.6% in the first 30 days, decreasing to 0.7% after this time. The authors use a protocol of imaging the ruptured aneurysms with enhanced MRA at the time of discharge, followed … Continue reading >>
