We report female patient, age 51, with clinically definitive multiple sclerosis (CDMS) since 1998, who underwent two PTA procedures with stent implantation for CCSVI in 2010. Expanded disability status scale (EDSS) worsened since the procedure from 4.5 to 6. Total number of three stents was implanted (two of them in the right internal jugular vein). In six month time, in 2011, patient was referred for independent examination by computer tomography (CT) phlebography for right-sided neck pain. Dislocation of stents on the right side and thrombosis of left sided stent was found. Conservative approach was used so far. Our short report is showing possible complications of PTA and stenting in jugular veins in so called CCSVI and bringing information about neurological state (EDSS) worsening in a subject. Continuation of stent migration in the future is probable, possibly resulting in pulmonary embolism with fatal risk for the patient. We strongly ask for restriction of PTA procedure in so called CCSVI, which concept was not proven to be relevant to MS.

    • "Following first reports on the efficacy of this method, particularly with respect to the relapsing-remitting disease [25], other reports were published suggesting lack of positive effects of angioplasty procedures [26,27] and discrepancies between treatment results as measured by the assessment of clinical status (Expanded Disability Status Scale, EDSS) and the extent of MRI lesions and the results of subjective quality of life assessment (MSQoL) [28]. Single reports of complications related to angioplasty procedures [29] and stent implantation [30] were also published. In 2011, CIRSE published a comment in which the routine use of this method is not recommended [31]. "

    ABSTRACT: Though the etiology of multiple sclerosis remains unknown, the widely accepted explanation is that it has an autoimmune inflammatory background. In 2006 Paolo Zamboni renewed the somewhat forgotten vascular theory of the pathogenesis of multiple sclerosis, proposing the new entity of ‘chronic cerebrospinal venous insufficiency’. As a result of this hypothesis, Zamboni suggested an endovascular treatment for multiple sclerosis involving venoplasty of the internal jugular vein and the azygos vein. Unfortunately, several teams have tried to replicate Zamboni’s results without success. In this review, we present a chronological description of the results of the studies conducted by Zamboni and the later attempts to replicate his work. The main conclusion is that, taking into account results that are currently available, we should remain cautious and routine use of this treatment in patients should not be advisable.

    ABSTRACT: The role of the extracranial venous system in the pathology of central nervous system (CNS) disorders and aging is largely unknown. It is acknowledged that the development of the venous system is subject to many variations and that these variations do not necessarily represent pathological findings. The idea has been changing with regards to the extracranial venous system. A range of extracranial venous abnormalities have recently been reported, which could be classified as structural/morphological, hemodynamic/functional and those determined only by the composite criteria and use of multimodal imaging. The presence of these abnormalities usually disrupts normal blood flow and is associated with the development of prominent collateral circulation. The etiology of these abnormalities may be related to embryologic developmental arrest, aging or other comorbidities. Several CNS disorders have been linked to the presence and severity of jugular venous reflux. Another composite criteria-based vascular condition named chronic cerebrospinal venous insufficiency (CCSVI) was recently introduced. CCSVI is characterized by abnormalities of the main extracranial cerebrospinal venous outflow routes that may interfere with normal venous outflow. Additional research is needed to better define the role of the extracranial venous system in relation to CNS disorders and aging. The use of endovascular treatment for the correction of these extracranial venous abnormalities should be discouraged, until potential benefit is demonstrated in properly-designed, blinded, randomized and controlled clinical trials.Please see related editorial:

    ABSTRACT: Background Chronic cerebrospinal venous insufficiency (CCSVI) has recently been introduced as a chronic state of impaired cerebral or cervical venous drainage that may be causally implicated in multiple sclerosis (MS) pathogenesis. Moreover, percutaneous transluminal angioplasty of extracranial veins termed “Liberation treatment” has been proposed (based on nonrandomized data) as an alternative therapy for MS.MethodsA comprehensive literature search was conducted to identify available published, peer-reviewed, clinical studies evaluating (1) the association of CCSVI with MS, (2) the reproducibility of proposed ultrasound criteria for CCSVI detection (3) the safety and efficacy of “Liberation treatment” in open-label and randomized-controlled trial (RCT) settings.ResultsThere is substantial heterogeneity between ultrasound case–control studies investigating the association of CCSVI and MS. The majority of independent investigators failed to reproduce the initially reported high prevalence rates of CCSVI in MS. The prevalence of extracranial venous stenoses evaluated by other neuroimaging modalities (contrast or MR venography) is similarly low in MS patients and healthy individuals. One small RCT failed to document any benefit in MS patients with CCSVI receiving “Liberation treatment”, while an exacerbation of disease activity was observed. “Liberation treatment” has been complicated by serious adverse events (SAEs) in open-label studies (e.g., stroke, internal jugular vein thrombosis, stent migration, hydrocephalus).ConclusionCCSVI appears to be a poorly reproducible and clinically irrelevant sonographic construct. “Liberation treatment” has no proven efficacy, may exacerbate underlying disease activity and has been complicated with SAEs. “Liberation treatment” should stop being offered to MS patients even in the settings of RCTs.
