Study To Evaluate Treating Chronic Cerebrospinal Venous Insufficiency (CCSVI) in Multiple Sclerosis Patients
- Conditions
- Multiple Sclerosis
- Interventions
- Procedure: VenoplastyProcedure: Sham procedure (non-treatment)
- Registration Number
- NCT01089686
- Lead Sponsor
- Manish Mehta, MD
- Brief Summary
This is a single center, multispecialty, randomized double blind placebo control feasibility clinical trial. The purpose is to evaluate the safety, feasibility and efficacy of percutaneous transluminal angioplasty in treating extracranial venous obstructive lesions, and its influence on the clinical outcomes of Multiple Sclerosis (MS) patients that have been found to have chronic cerebrospinal venous insufficiency (CCSVI).

Group Intervention Description Venoplasty (treatment) Venoplasty Patients will be randomized to treatment or non-treatment arm with a 2:1 ratio. Patients who meet the inclusion/exclusion criteria and who are randomized to the treatment arm of the study will receive venoplasty at the time of the diagnostic venogram. Sham procedure (non-treatment) Sham procedure (non-treatment) Patients will be randomized to treatment or non-treatment with a 2:1 ratio. Patients who meet the inclusion/exclusion criteria and who are randomized to the non-treatment arm of the study will receive the diagnostic venogram only.
- Primary Outcome Measures
Name Time Method Incidence of major adverse events 30 days The evaluation of safety will be defined as the incidence of major adverse events at 30 days following the index procedure. The evaluation of feasibility and efficacy will be determined by those patients that do not have more than 50 percent restenosis within the 30 day time frame.
Neurological assessment of MS 1 year An independant neurologist will assess the number of MS attacks that have occurred during one year follow up period.
MRI/MRA evaluation of MS lesions, recommended 1 year Evaluation of imaging to reveal local iron content, change in MS lesions and oxygen saturation changes using conventional MRA/MRI methods by an independant radiologist.
- Secondary Outcome Measures
Name Time Method Mortality 1 year All cause mortality will be evaluated through one year.
Major adverse events 1 year Incidence of all major adverse events will be collected for one year.
Identification of central venous stenosis 1 year Evaluation of the correlation between MRV, Duplex Ultrasound and Venogram in identifying central venous stenosis.
