The significance of the safety report on endovascular treatment for chronic cerebro-spinal venous insufficiency (CCSVI) in patients with multiple sclerosis (MS) by Petrov et al. should not be underestimated. This is the largest series reported in the world to date of patients undergoing venoplasty for CCSVI, a treatment that does not currently have the universal support of the medical community. Nowadays, healthcare systems are reluctant to introduce any new treatment without a strong consensus of acceptance corroborated by good clinical data, so the lack of clinically significant complications in almost 500 procedures certainly supports wider acceptance of this new endovascular therapy. This is, therefore, an important publication.
