Dear Readers, It gives me great pleasure to present this edition of Intervention IQ, with venous interventions as the leading theme. When we talk of venous disorders, many people might think only of unsightly varicose veins and underestimate them as merely a cosmetic problem. However, visible varicose veins are just one sign of chronic venous insufficiency; a disease state that has serious implications fo

Patient Story

The IR Way The Patient Ms. feraye kılıç, a patient of Prof. Levent Oguzkurt, explains how undergoing interventional radiology (IR) treatment for varicose veins made a real difference to her life: “After my second pregnancy, unsightly varicose veins appeared on my left leg and got larger and larger over the last three years. The appearance was only one part of the problem. In my right leg, there was

Varicose Vein Treatment the IR Way

Prof. Levent Oguzkurt spoke to IQ about the particular strengths of interventional radiologists, which enable them to provide excellent treatment for symptomatic varicose veins: “Our hospital is one of the biggest centres in Turkey for laser ablation of varicose veins. Since 2007, when we started providing IR treatments for this condition, we have performed more than 1,500 thermal ablation pro - cedur

New Horizons

Innovation and constant technical development are some of the hallmarks of interventional radiology (IR). One area in which interventional radiologists are applying their ingenuity is in the search for a new solution to chronic venous insufficiency (CVI). Thanks to the great contribution of Prof. Elias Brountzos and Prof. Dusan Pavcˇnik, two interventional radiologists in volv ed in this field of research


Minimally invasive treatments for varicose veins are offering patients more choice than ever, and even where they are not offered by public health insurers, patients are voting with their wallets and seeking out private treatment. Dr. Kieran McBride runs the Scottish Vein Centre, a private clinic in Edinburgh that offers varicose vein sufferers the gentle options they are looking for. He tells us why the

Dr. Sanjoy Kundu,Medical Director of the Vein Institute of Toronto and Active Staff at the Scarborough Hospital, Toronto/Canada “Image-guided treatments for varicose veins, including endothermal ablation and ultrasound-guided sclero the ra py, have revolutionised the treatment of superficial venous insufficiency. These treatments are characterised by markedly improved outcomes, decreased complications and

Deep vein thrombosis (DVT), often referred to as Economy Class syndrome, is a well-known medical complaint much discussed in lifestyle magazines. unsurprisingly – in a world where long-haul flights and sedentary lifestyles are so prevalent, we are more at risk than ever before. What is DVT? DVT is the formation of a blood clot within the veins that lie deep within our muscle tissue. This is most commo

Why is it Important to Treat DVT – What can be the Consequences of Not Doing so? “DVT can have serious consequences: venous thrombo - embolism (VTE) is the third biggest cause of cardiovascular mortality after stroke and heart attack. Additionally, post-thrombotic syndrome affects a large proportion of patients post-DVT and is disastrous in terms of morbidity. Multiple long-term studies have shown huge

Dr. Maccon Keane is a Medical Oncologist at University Hospital, Galway. He is a keen supporter of IR, and works closely with Gerard O’Sullivan and his colleagues. “Our Oncology Department has been working closely with the IR Department since 2003. Oncology patients, due to a variety of factors, such as altered blood chemistry and increased bed rest, are quite prone to developing blood clots. They’

Venous Interventions

Circulation When everything is running smoothly, most people don’t give their circulation much thought. But silently and out of sight something impressive is happening. The heart pumps the equivalent of approximately 7,000 lit - res of blood around the body each day. Blood is first sent along the arteries, delivering oxygen from the lungs to the other organs and tissues. Then it is the job of the veins

The Treatment Radiofrequency (RF) ablation is one of the common ways to treat symptomatic varicose veins by applying endovenous heat. With the latest technology a catheter with an RF tip is inserted into the varicose vein and advanced to where the treatment should begin, which is typically at the groin level. The RF tip heats each segment to 120°C for 20 se - conds, as the catheter is carefully pulled

The Treatment Laser ablation (also called endovenous laser treatment or ELT/EVLT) is very similar to radiofrequency (RF) ab lation: by applying heat from within, the malfunctioning vein can be sealed off. In a similar manner to RF ablation, a very thin laser fibre is inserted into the vein under local anaesthetic. Once in place, the laser is switched on and slowly withdrawn down the vein. The heat literall

A third minimally invasive treatment option is foam sclerotherapy, which acts differently to the thermal ablative techniques. Dr. Kieran McBride, who runs a private vein clinic in Edinburgh, Scotland, talks us through its uses and advantages. “There is certainly a role for foam sclerotherapy in treating varicose veins, as well as other venous malformations. While laser has shown to be the most effective

Apart from the minimally invasive treatments provided by interventional radiology (IR), there are a number of other strategies available for the management of symptomatic varicose veins. Conservative Management Graduated compression hosiery is a mainstay of managing venous insufficiency. Specially designed to provide more compression at the bottom of the leg than the top, the poor functioning of the vein

The previous pages have shown a range of interventional radiology (IR) treatments which are available for the effective management of venous disorders. Interventional radiologists combine imaging expertise and technical skill with catheters and guidewires; allowing treatment of the problem at source. However, not all venous interventions are in response to a venous disorder. Sometimes the veins are used

Trial: a study carried out with the purpose of testing a new medical treatment on a defined group of people. The results are compared with a group that are treated using another method and/or a control group. Registry: a (retrospective) collection of data about a certain treatment or illness. using the compiled data, conclusions can be drawn about effectiveness of a particular treatment method. Early Out

Health Economics

The high cost of venous disorders is guaranteed by the sheer number of people affected. Alongside the expen - ses of acute treatment and long-term care, the wider economy must absorb associated costs, such as the high number of missed work days. A European Example: The Situation in Germany Chronic Venous Disease A German study into the prevalence of venous disorders found every 6th man and every 5th woman

In an ideal world, patients would have unlimited access to all the treatments they might need. In re ality, however, healthcare decision makers face the difficult task of balancing need with availability. With limited resources, cost effectiveness is central to any decision. Lieven annemans, Professor of health Economics at Ghent university and Brussels university (VuB) and author of “health economics

Daily Practice

The smallest patients need special care, and that is precisely what paediatric interventional radiologists provide. although a rare breed, there is great interest in this sub-specialty, with many children's hospitals offering a paediatric interventional radiology (IR) programme, or looking to begin one. IQ talks to Dr. anne-Marie Cahill, director of the Paediatric IR programme in the Children’s hospita
