Delegates attending the CX Vascular Malformations Management session on Thursday 30 April, in the afternoon, will get a general overview of congenital vascular malformations and will also learn about the latest advancements in the field.  

This year, the course will include keynote lectures covering the topics of venous, lymphatic, combined and arteriovenous malformations each followed by case presentations illustrating representative clinical situations. The role of imaging of vascular malformations and treatment options including embolisation, sclerotherapy and laser therapy will be addressed.   

The session, led by Iris Baumgartner, Bern, Switzerland, will be interactive allowing the audience to get feedback from a panel, which includes the experts: Raul Matassi, Matthias Widmer, Joe Brookes, Andreas Saleh and Martin Köcher.

The CX Vascular Malformations Management session will take place at the Charing Cross Symposium on Thursday 30 April (afternoon) – London Room Learning Centre, Olympia Grand, London, UK.

In 2015, the Charing Cross Symposium will dedicate, for the first time, four days of discussion in the venous field addressing both the superficial and deep venous systems. The Symposium is also launching a new CX Venous Workshop, formerly named as CX Office-Based Vein Practice Course, which includes hands-on training on the latest techniques for varicose veins treatment and, for the first time, practical training on deep venous treatment.   

On the first day (Tuesday, 28 April) upcoming leading vascular and endovascular experts will present cutting-edge venous investigation at a CX Abstracts‒Venous session. Delegates will also have the chance to visit the CX Venous Workshop, which will run on the following days (Wednesday, 29 April and Thursday, 30 April). On the fourth day, the CX Main Programme will be dedicated to Venous Controversies.

Superficial and deep venous treatment at the core of the Venous Controversies        

This year’s Venous Controversies in varicose veins treatment are no longer between surgery and office-based techniques, according to Roger Greenhalgh, (Imperial College, London, UK), chairman of the CX Programme Organising Board. “It seems as if office-based vein techniques have swept the board. Now the controversy seems to be about which method to select in which situation,” he says.

Delegates will learn the latest evidence on varicose veins treatment options with thermal and non-thermal techniques. “We will try to present a balance between data and information that relate to office-based tested techniques that are already established and are probably state-of-the-art alongside techniques that are emerging, and that may not have enough data but nonetheless might represent a completely shift in practice. We are happy for people to find out about these new techniques at Charing Cross first,” says Ian Franklin (London, UK), member of the CX Programme Organising Board.  

Commenting on non-thermal techniques, Mark Whiteley (University of Surrey, London, UK), also a member of the CX Programme Organising Board, says: “The newer non-thermal techniques are now joining the endovenous thermal ablative devices and starting to show impressive results. The controversy here will be whether these newer non-thermal methods are now able to replace endothermal ablation in some or all cases.” (See an interview with Whiteley on varicose veins treatment).  

Sclerotherapy and laser therapy of cosmetic skin problems will also be discussed.

Deep venous treatment is another major topic of controversy at this year’s CX Symposium. Franklin comments: “Deep venous thrombosis treatment is controversial because it is extremely badly managed in many countries and some people get almost no treatment at all. Nowadays, there are new technologies that help physicians treat deep venous thrombosis effectively. There is a lot to achieve in terms of training and education on how to diagnose deep venous thrombosis promptly with the right method of treatment to guarantee durable results.”

Stephen Black (Guy’s and St Thomas NHS Foundation Trust, London, UK), member of the CX Programme Organising Board, considers that there is a real need to develop the evidence base for treatment options for deep venous thrombosis. At the session on Deep Venous Controversies, delegates will learn about the latest evidence on the current techniques for deep venous thrombosis treatment including new stents and catheter-directed thrombolysis and thrombectomy techniques. (See an interview with Black on deep venous disease treatment).     

Imaging for superficial and deep venous treatment is playing a vital role in the diagnosis of these anomalies. Greenhalgh comments: “It appears that imaging is absolutely at the core of intervention in the superficial and deep venous systems. Unfortunately, venous imaging is less than helpful when the patient lies flat and how to image the deep venous system with the patient standing will be discussed.”

The use of current imaging technologies such as duplex, magnetic resonance imaging (MRI) and intravascular ultrasound (IVUS) will be discussed at a session dedicated to this field.

New CX Venous Workshop   

The former CX Office-Based Vein Practice Course has changed its name to the CX Venous Workshop because it now encompasses all aspects of venous disease including deep vein thrombosis, intravascular ultrasound and deep vein stenting. The course will continue providing delegates with hands-on training sessions for varicose veins treatment. In 2014, it had a record attendance of over 700 delegates during two days.

The CX Venous Workshop is set out in a very flexible format and will run from 10am until 3pm over two days. There will be different training stations (around 30) led by a physician expert who will be demonstrating a wide range of techniques and procedures in different superficial and deep venous treatment techniques. There is not a rigid timetable and participants can choose their timing at their convenience. The course facilitates one-to-one interaction or discussions in small groups.

Key areas covered include:                                                      

• Practical training
• Truncal ablation
• Diagnostic venous ultrasound
• Anatomy
• Venous haemodynamics
• Sclerotherapy
• Thread veins
• Dermal lasers
• Pelvic venous imaging
• Pelvic congestion
• Pelvic veins and haemorrhoids

Venous surgeons and phlebologists are spoiled for choice when it comes to office-based technology options for varicose veins. This brings questions such as what technologies are best suited for what patients, what factors should be considered to obtain best results and what is the role of open surgery in the field. Mark Whiteley (University of Surrey, London, UK), member of the CX Programme Organising Board, gives his views on the subject. The latest evidence in this area will be discussed in the Venous Controversies sessions of this year’s CX Main Programme.    

Physicians now have a great selection of office-based technologies for the treatment of varicose veins; what method is best for what case?

This has been the major area of my research since starting radiofrequency ablation in March 1999 and it is fair to say that there are many different opinions on this. Most importantly, before this question can even be considered, we need to decide on what constitutes “the best”. In my view, technical perfection is the correct outcome, as this will lead to long-term success and therefore should lead to long-term patient improvement.

However, advocates of techniques with inferior technical results that might require less intervention or fewer injections, point to patient satisfaction as the correct outcome measure to use to assess “the best” treatment method. I believe this is not a good outcome measure to use scientifically. Patient satisfaction can be manipulated by factors other than the treatment itself, particularly by misinformation given to patients in some studies by advocates of one method as to the theoretical risks of other methods that might be used.

In addition, satisfaction has to be measured at one or several points in time—often in the relatively short term. Technical imperfections which are likely to progress to recurrence and reduced patient satisfaction in the long term might be present in the short term. But measuring patient satisfaction alone may miss these out due to the time it takes for the patients to experience the clinical outcomes of the treatment failures.

What factors should be considered to obtain best results in varicose veins treatment?

As with all surgical techniques, there are several factors involved in obtaining the best results. Not only does the technology and device design have to be adequate to the job, but the patient selection needs to provide appropriate cases for the chosen technique and doctors and their teams need to use adequate imaging and procedural technique to get the optimal results.

In addition, patient expectation has to be added, such as whether they are looking for relief of symptoms only or cosmetic perfection and also an acceptable cost for the service.

What office-based technologies are currently showing best results?

Generally, in most hands, endovenous thermoablation shows excellent results for truncal and perforator veins ablation, provided the correct technique is used and an appropriate device for the vein to be treated. Glue and mechanochemical endovenous ablation (MOCA) are starting to show promising results in truncal venous reflux in selected patients whereas foam sclerotherapy is technical disappointing in truncal veins. However, advocates will point to patient satisfaction and re-treatments to argue for its use.

Currently, coil embolisation of refluxing pelvic veins with foam sclerotherapy seems to be the optimal treatment for pelvic venous reflux. Foam sclerotherapy alone or ligation of veins at the pelvic exit points are used by some but need to be proven as effective and acceptable treatments. 

For incompetent tributaries and varices, ambulatory phlebectomy is probably optimal for larger veins and foam sclerotherapy for smaller veins— although the new technique of combining both as “foam phlebotomies” is gaining popularity in the USA.

When it comes to neovascular tissue, strip tract revascularisation, feeding veins under patches of telangiectasia and primary avalvular varicose anomalies (PAVA) then foam sclerotherapy is the only effective option.

Finally, for telangiectasia themselves, microsclerotherapy is still the best option as it treats both the visible veins as well as the communicating veins hidden below the surface.

With the outcome of many office-based technologies and their comparable efficacy results with surgery, is there still room for surgery?

No.

Unless one calls ambulatory phlebectomies (surgery), then there is no need to ever perform open surgery for varicose veins anymore. Personally, I have not had to use open surgery for any varicose veins case for over a decade.

At the debate “Duplex scanning is mandatory before treatment of asymptomatic cosmetic thread veins” you will present “For the motion”. Could you tell us the reasons as to why you are supporting this practice?

Since 2001, increasing numbers of research papers have shown that cosmetic thread veins frequently occur in association with underlying venous reflux. In many, if not the majority of cases, this venous reflux leads directly into the thread veins. Furthermore, every case of the complication called telangiectatic matting that I have ever seen after thread vein treatment, has an underlying untreated vein refluxing into the affected patch.

Since instituting a policy of duplex scanning in 2002 in which every patient presenting with cosmetic thread veins of the legs are treated for any underlying venous reflux before proceeding to microsclerotherapy of the thread veins themselves, we have never had a case of telangiectatic matting. Those cases presenting to us with this complication from elsewhere invariably have an underlying vein refluxing into the lesion.

With the explosion of cosmetic clinics starting to offer thread vein treatments, often without duplex ultrasound or even hand held Doppler, it is essential for us as phlebologists and venous surgeons to state that we feel that treatment of thread veins without a duplex ultrasound scan first is a sub-optimal treatment.
