3 Debates can be more easy or more difficult
This is one of the easiest I ever had

4 Everything is worth investigating!
Why? Everything is worth investigating!

5 It is common for all new discoveries that nobody could believe it or even think about it before it was discovered

6 Nobody could even think about it before it was done
Antibiotic treatment of gastric ulcer Bypass surgery PCI TAVI Driving a car Flying to the moon The wheel America

7 The concept of venous angioplasty for MS
MS is the result of venous obstructions of cerebral and spinal cord veins Or these obstructions aggravate MS Treatment of these obstructions can Improve symptoms and/or slow down or even reverse progression of MS

8 What is MS? An inflammatory demyelinating disease
currently considered to be an autoimmune disease Wide range of symptoms Paresthesia, ataxia, dysarthria, pain, fatigue,…. Incidence 1 : 1,000 Associated with Past Ebstein-Barr virus exposure History of smoking Living far away from the equator Living close to high altitudes Some genetic factors

9 What does MS mean for the economy and the health care system?
In hospital treatment or one single relapse costs > 12,000 US $ Annual costs are > 47,000 US $ per patient Total annual costs in the UK: 1.4 billion GBP O'Brien et al, BMC Health Serv Res 2003, 3:17

10 What does MS mean for the individual patient?
A progressive disease which leads to severe disability and/or death No effective therapy available Medical therapy has severe side effects including immune deficiency and cancer

11 Cerebral and central venous duplex
Zamboni et al: Chronic cerebrospinal venous unsufficiency in patients with multiple sclerosis. J Neurol Neurosurg Psychiatry 2009, 80:358 65 patients with MS 235 controls Cerebral and central venous duplex Blinded analysis Venography in patients with flow abnormalities

12 Duplex MS patients controls p 71% 0% < 0.0001 61% 37% 52% 3% 55%
IJ or vertebral venous refux 71% 0% < Deep cerebral venous reflux 61% B-mode demonstration of venous stenosis 37% IV or vertebral occlusion 52% 3% Failure of IV to dilate in recumbency and/or collapse when erect 55% 11% Zamboni et al: J Neurol Neurosurg Psychiatry 2009, 80:358

13 Venography Patients with at least 2 duplex findings had significant extracranial venous stenosis Jugular stenosis: 91 % Azygos vein stenosis 86 % Zamboni et al: J Neurol Neurosurg Psychiatry 2009, 80:358

14 70 patients with MS Age 15-58 Symptoms 0.5-40 yrs
Simka et al: Extracranial doppler sonographic criteria of chronic cerebrospinal venous insufficiency in patients with multiple sclerosis. Int Angiology 2010, 29:109 70 patients with MS 49 relapsing-remitting 5 primary progressive 16 secondary progressive Age 15-58 Symptoms yrs

15 IJ or vertebral reflux 43% IJ stenoses 87%
Simka et al: Extracranial doppler sonographic criteria of chronic cerebrospinal venous insufficiency in patients with multiple sclerosis. Int Angiology 2010, 29:109 ≥ 2 Zamboni criteria 90% IJ or vertebral reflux 43% IJ stenoses % IJ or vertebral occlusion 53% Abnormal IJ response to standing % Conclusion: Multiple sclerosis is highly correlated with chronic cerebrospinal venous insufficiency

16 Venous angioplasty in 65 patients with MS Mean FU 18 mo Results
Zamboni et al: Prospective open-label study of endovascular treatment of chronic cerebrospinal venous insufficiency. J Vasc Surg 2009, 50:1348 Venous angioplasty in 65 patients with MS Mean FU 18 mo Results 50% relapse free Pts with active MS lesions 50%12% Significant symptomatic improvement in the majority of patients

17 What supports the theory of CCSVI?
MS plaques have a perivascular distribution MS Lesions have an increased parenchymal iron deposition (like in venous stasis) Venous abnormalities in MS had been described by others decades before Zamboni Leriche et al, Acta radiol Suppl 1976 Aboulker et al, Acta Radiol Suppl 1976 Brunereau et al, Am J Beuroradiol 1996

18 Current Status of Venoplasty
Almost 1000 patients have been treated worldwide Very low risk Only very few severe complications After stent implantation Patients do not have an alternative Medical therapy is ineffective and has severe side effects Cardiotoxicity Bone marrow suppression Neoplasms immunosuppressive

19 The clinical benefit of the procedure is amazing
I would wish that all our procedures do have such a clinical benefit

20 -----Ursprüngliche Nachricht----- Von: Maureen Browne Gesendet: Sonntag, 11. Juli :04 An: S. Dancsecz Betreff: AW: Dr Sievert Dear Dr Sievert Thank you for the reply to my last . Firstly, may I report that I have noticed difinite cognitive improvements in the last week. I cannot begin to verbalize my appreciation for this. Cognitive function is the most dreaded loss in the ms scenario. At the onset of my ms, I always feared losing the function of my legs -but I have already spent time in a wheelchair and that is insignificant compared to loss of brain function. My headaches have virtually disappeared. Sincerely Maureen

21 -----Message d'origine-----> De : Lucie Godbout [mailto:lucie
-----Message d'origine-----> De : Lucie Godbout Envoyé : 7 décembre :49> À : Objet : RE: CCSVI diagnostic and treatment Hi, News from Canada: Before the intervention Jacques didn't feel his right leg and his right arm, he had extreme fatigue and had a speech problem at the end of the day. He also had problems of bladder. He couldn't work all week long and not long hours. As you saw the day after the intervention, Jacques was feeling much better. It's been almost 1 month since Jacques had the intervention. He has never felt better.  He doesn't have any symptoms anymore.  Everything is back to normal.  He restarted to work 5 days a week until 6:00PM.  He started to take some long walks, even a little bit of jogging, even if I told him it was too early to do so. Thanks again for everything! I will write to you in a month. Have a very Merry Christmas! Lucie and Jacques

22 Could it still be placebo?
Yes, of course

23 The topic is how to develop science and medicine
However, the topic of this debate is not whether or not venoplasty is effective in MS The topic is how to develop science and medicine

24 There is only one way To develop a new idea, concept, treatment
To test it first in case series and thereafter in randomized trials To implement it into clinical practice To validate the results in registries and clinical practice

25 Certainly Worth Investigating
