Just published in Veins and Lymphatics:
May symptoms of chronic cerebrospinal venous insufficiency be improved by venous angioplasty? An independent 4-year follow up on 366 cases
"In addition, venous angioplasty appears to be safe, side effects were observed only in seven patients (0.19%) that grew a monolateral Jugular thrombosis but still were regularly controlled and above all didn’t suffer worsening of the disease. Finally, the overwhelming PTA results in the RR group lead to say that the correct criteria should be the sooner the better."
