Earlier this year Juan Cebral's group published an interesting paper suggested that rare cases of aneurysm rupture following treatment by flow diverters might be due to treatment-induced pressure increases. Barry Lieber and colleagues subsequently questioned these CFD-based results, which brought a strong response from Cebral and colleagues. I was then asked by AJNR's Charlie Strother to help explain the controversy for the AJNR readership.
Who is right? This remains to be seen, but I see it as a terrific opportunity for our community to demonstrate the clinical value (or lack thereof) of image-based CFD.
