A growing body of evidence on the prevalence of CCSVI among people living with MS suggest that CCSVI is not associated with MS, and based on recent preliminary findings, venoplasty was shown to be ineffective as a treatment for MS. Researchers suggest that continued discrepancies in results between studies may be attributed to inconsistencies in imaging techniques, training of personnel, and interpretation of results.
Experts and journalists are reading whatever they want into a new study examining CCSVI in MS patients'
The study methods have been reviewed and approved by the institutional review boards of all participating institutions.
CCSVI is a term used to describe the narrowing of veins in the neck, which has been suggested to affect blood flow out of the central nervous system.
If this is the case, then they are missing are unwilling to say the obvious implication - Dr. Zamboni's original studies on CCSVI were flawed.
Dr. Field’s team is using alternative imaging methods, in addition to the ultrasound method used in Dr. Zamboni’s original reports, to conduct a controlled study of the CCSVI hypothesis in people with MS.

If you wish to have a doppler ultrasound you may contact our offices for a referral to a local ultrasonographer.
Steroids: If a flare gets in the way of your life, your doctor may give you high-dose steroids through a vein (intravenously) or by mouth to ease your symptoms quickly. These drugs will calm the flare, but they won't slow the course of your disease. The most common ones are:
El tinte de contraste fluye a través do esta linea hacia la vena. Se puede poner un torniquete en su pierna para que el tinte fluya hacia las venas más profundas.
Segundo o estudo recente, publicado no JAMA – Journal of the American Medical Association, o emprego do gadolÃnio Pode vir a aumentar o risco do este feto desenvolver um raro problema por visão.
Interestingly, in the sensitivity analyses of the Canadian study (excluding the studies by Zamboni and colleagues, removing unblinded studies and using a continuity correction of one for studies with zero cells that were originally excluded) the documented extensive heterogeneity was not reduced.
controls; OR values larger than 1 denote a positive association between MS and CCSVI diagnosed by at least two ultrasound criteria. For studies with a zero cell we used a continuity correction of 0.
The FDA sent a warning letter to a sponsor/investigator who was conducting a clinical study of CCSVI treatment without an approved vá aqui IDE. Because the FDA currently considers clinical studies evaluating CCSVI treatment with balloon angioplasty devices and/or stents to be significant risk, this study was in violation of the FDA’s regulations. The sponsor/investigator has reported the study has been voluntarily closed.
