The debate regarding the possible link between chronic cerebrospinal venous 
insufficiency and multiple sclerosis (MS) is continuously becoming more and more 
contentious due to the current lack of level 1 evidence from randomized trials. 
Regardless of this continued uncertainty surrounding the safety and efficacy of 
this therapy, MS patients from Canada, and other jurisdictions, are traveling 
abroad to receive central venous angioplasty and, unfortunately, some also 
receive venous stents. They often return home with few instructions regarding 
follow-up or medical therapy. In response we propose some interim, practical 
recommendations for post-procedural surveillance and medical therapy, until 
further information is available.
