An endovascular treatment of Chronic Cerebro-Spinal Venous Insufficiency in multiple sclerosis patients - 6 month follow-up results.
OBJECTIVE: In this study, the mid-term results (6 month follow-up) of the endovascular treatment in patients with Chronic Cerebro-Spinal Venous Insufficiency (CCSVI) and multiple sclerosis (MS) were prospectively evaluated.
METHODS: Thirty-six patients with confirmed MS and CCSVI underwent endovascular treatment by the means of the uni- or bilateral jugular vein angioplasty with optional stent placement. All the patients completed 6 month follow-up. Their MS-related disability status and quality of life were evaluated 1, 3 and 6 months postoperatively by means of the following scales: Expanded Disability Status Scale (EDSS), Multiple Sclerosis Impact Scale (MSIS-29), Epworth Sleepiness Scale (ESS), Heat Intolerance scale (HIS) and Fatigue Severity Scale (FSS). For patency and restenosis rate assessment, the control US duplex Doppler examination was used.
RESULTS: Six months after the procedure, restenosis in post-PTA jugular veins was found in 33% of cases. Among 17 patients who underwent stent implantation into the jugular vein, restenosis or partial in-stent thrombosis was identified in 55% of the cases. At the 6 month follow-up appointment, there was no significant improvement in the EDSS or the ESS. The endovascular treatment of the CCSVI improved the quality of life according to the MSIS-29 scale but only up to 3 months after the procedure (with no differences in the 6 month follow-up assessment). Six months after the jugular vein angioplasty (with or without stent placement), a statistically significant improvement was observed only in the FSS and the HIS.
CONCLUSIONS: The endovascular treatment in patients with MS and concomitant CCSVI did not have an influence on the patient's neurological condition; however, in the mid-term follow-up, an improvement in some quality-of-life parameters was observed....
