A single report of 33-year-old lady with MS who underwent left internal jugular venoplasty (opening of the narrowing) resulting in jugular thrombosis (clot) requiring open removal of the clot (thrombectomy) for symptom relief. This occurred without insertion of a stent and while fully anticoagulated (drugs to thin the blood an preventing clotting).
Conclusion: MS'ers and Clinicians should be aware that endovenous treatment ofCCSVI could cause paradoxical deterioration of cerebral venous drainage. MS'ers with complications post venoplasty are now presenting to geographically distant vascular units.
