The patients get a catheter venogram done, where someone who is not an expert at CCSVI threads a catheter through the patient's veins and heart to reach the jugulars, and if the IR finds any CCSVI stenoses, he will not treat them.•Dr. Jerry Wolinsky, University of Texas Health Science Center at Houston:
The team reports that they have recruited about 82% of the expected study cohort. The cumulative number of volunteers recruited from study inception includes: 10 Healthy Volunteers; 34 Other Neurological Diseases; 22 Stroke/TIA; 12 CIS; 112 relapsing-remitting MS; 44 secondary-progressive MS; 1 progressive-relapsing MS; 15 primary-progressive MS. Of people with MS or CIS, 45 have undergone MR venography with advance MRI. In addition, to date 10 people with MS have consented to transluminal venography, 2 are scheduled for study and 4 have completed the procedure without complications. No therapeutic interventions are considered in these investigations.
Exactly what is in this for the patient?? Yes, contributing to research is good, but any information gained for the patient on a personal level (such as the identification of stenoses in the jugulars or azygous) could've been gained noninvasively, with the catheter venogram done only as part of the procedure itself, in which a balloon is indeed inflated and the stenoses go away and, with any luck, one's health improves.
So close and yet so far, for the patients participating in this study....
