A randomized, double-blind, sham-controlled trial, Brave Dreams, has shown no clinical or radiological benefit of percutaneous transluminal angioplasty (PTA) to correct chronic cerebrospinal venous insufficiency in patients with multiple sclerosis (MS). These results finally settle the scientific debate over whether PTA can improve clinical, radiological and symptomatic outcomes in this patient population.
