Purpose: To assess the safety of endovascular treatment of chronic cerebrospinal venous insufficiency (CCSVI) in patients with multiple sclerosis (MS)., Materials and Methods: A total of 72 patients with CCSVI and MS (44 with relapsing remitting--RR, 4 with primary progressive, 20 with secondary progressive and 4 with benign MS) underwent percutaneous angioplasty. Outcome measures were colour Doppler ultrasonography parameters, gradient pressure at the vein abnormality level, postoperative complications, re-stenosis, disease severity scored by means of Expanded Disability Status Scale (EDSS) and patients' assumption of disease status. Controls were done after one month on 72 patients, six months on 69 patients and one year on 61 patients, respectively (the average follow-up was 11 months)., Results: There were no postoperative complications. Colour Doppler ultrasonography showed significant improvement in cross-sectional area parameters (P < 0.05) and significant decrease in confluence velocity values (P < 0.05). Postoperative gradient pressure decreased, in internal jugular vein (IJV) significantly (P < 0.05). Re-stenosis appeared in 5.3% of patients. EDSS score was significantly improved (P < 0.01) and about half of patients reported significant or mild improvement in disease status and none of them worsening of symptoms., Conclusion: Endovascular treatment of the IJV and azygous veins in patients with CCSVI and MS is a safe procedure with no post-procedural complications followed by significant improvement of IJV flow haemodynamic parameters and decrease in the EDSS score. Whether CCSVI percutaneous treatment might affect clinical improvement in patients suffering from MS is yet to be seen after completion of major multicentric clinical trials, still it seems like that this procedure is not negligible., (© The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Objectives: Condition known as chronic cerebrospinal venous insufficiency (CCSVI) is characterized by insufficient cerebral vein drainage in patients with multiple sclerosis (MS) and internal jugular vein (IJV), vertebral and/or azygos veins stenoses. However, external compression on the IJV was not clearly described as a potential cause of CCSVI. We aim to present a case of CCSVI in a patient with MS caused by bilateral IJV inverted valves combined with IJV external compression by carotid bulb., Methods: A 31-year-old female patient was admitted to our institute for IJV and vertebral veins morphological and haemodynamical assessment after being treated for MS for the last 14 years. Colour Doppler ultrasonography showed right IJV prestenotic dilation and inverted valves in both IJV. Computerized tomography angiography showed bilateral IJV compression by carotid bulb. Haemodynamical Doppler parameters showed that external IJV compression significantly contributed to CCSVI occurrence., Results: Bilateral IJV confluence percutaneous angioplasty (PTA) was done, and the patient was discharged for further neurological examination. Partial carbon dioxide pressure was significantly lower in the distal part of both IJV following PTA and oxygen saturation increased., Conclusion: In the case presented, PTA of the IJV confluence resulted in haemodynamic improvement despite the presence of IJV external compression.

Objectives: Multiple areas of stenosis and different levels of obstruction of internal jugular and azygous veins (a condition known as cronic cerebrospinal venous insufficiency) recently emerged as an additional theory to the well-known autoimmune concept, explaining etiology of multiple sclerosis (MS). The aim of our study was to evaluate internal jugular vein (IJV) morphology and haemodynamic characteristics in patients with MS and compare it with well-matched healthy individuals and to evaluate the prevalence of venous flow abnormalities in both groups., Methods: Sixty-four patients with clinically proven MS and 37 healthy individuals were included in our study. In all patients, IJV morphology and haemodynamic characteristics were evaluated by colour Doppler sonography as well as venous flow disorder. The patients were classified into four groups according to MS clinical form presentation. The prevalence of morphological and haemodynamic abnormalities in the IJV were assessed., Results: The presence of stenosing lesion, mostly intraluminal defects like abnormal IJV valves, were observed in 28 patients (43%) in the MS group, and in 17 patients (45.9%) in the control group (P = NS). By adding haemodynamic Doppler information in the IJV venous outflow was significantly different in 42% of MS patients showing flow abnormalities (27/64), as compared with 8.1% of the controls (3/37), P < 0.001., Conclusion: In our group of patients, patients suffering from MS had significantly more IJV morphological changes and haemodynamic abnormalities when compared with healthy individuals not suffering from MS. These findings can be well demonstrated by non-invasive and cost-effective Doppler ultrasound.

Different internal jugular vein (IJV) abnormalities can be found in patients with multiple sclerosis (MS): stenoses, complete occlusion, distortions and intraluminal structures, such as membranes, webs and inverted valves. IJV duplication is a very rare phenomenon. We report a case of right IJV duplication as an incidental finding during IJV morphological and haemodynamic assessment in a patient with MS. A 55-year-old female patient was admitted to our Institute for IJV and vertebral veins morphological and haemodynamic assessment. During the last seven years she had been treated for MS. Colour Doppler ultrasonography in our patient did not reveal IJV or vertebral veins stenoses or abnormal valves, but instead right IJV duplication. This finding was confirmed using multislice computed tomography angiography and by selective phlebography. In conclusion, to our knowledge, a case of IJV duplication in a patient with MS has not been described yet. This further venous malformation can be assessed by the means of Doppler ultrasounds.
