abstract

  • PURPOSE: This study proposed to prospectively evaluate safety and clinical changes in outpatient endovascular treatment in patients with multiple sclerosis (MS) and chronic cerebrospinal venous insufficiency (CCSVI). MATERIALS AND METHODS: Two hundred fifty-nine patients with MS were followed with the Multiple Sclerosis Impact Scale (MSIS-29) before and for 1 and 6 months after treatment of extracranial internal jugular vein and azygos vein stenoses and occlusions using venous angioplasty, as well as stent placement in 2.5% of patients. Before treatment, the patients were tested with magnetic resonance (MR) venography and flow quantification. RESULTS: We found statistically significant improvements in the MSIS-29 scores (P < .01) at both 1 and 6 months. At 1 and 6 months, 67.9% and 53.6% were improved on the physical scale, respectively, and 53.0% and 44.4% were improved on the psychological scale, respectively. Women showed greater improvement than did men on the physical scale at 6 months (P = .01). Patients with primary progressive MS (PPMS) showed less improvement than did those with relapsing-remitting MS (RRMS) on the psychological scale at 1 month, and venoplasty treatment of more vein sites versus fewer vein sites showed greater improvement on the physical scale at both 1 and 6 months. Fifteen patients (6.3%) reported recurrent symptoms after clinical improvement and were treated again. There was one serious adverse event, a deep venous thrombosis at the catheter insertion site, which resolved with treatment. CONCLUSIONS: Endovascular treatment of CCSVI in patients with MS appears to be a safe procedure resulting in significant clinical improvement.
