Vascular & Endovascular Surgery

Endovascular Surgery is a form of minimally invasive surgery designed to access various regions within the body via the major blood vessels. The word ‘endovascular’ combines ‘endo,’ meaning within, and ‘vascular,’ related to blood vessels. It provides an alternative approach to open surgery and can be used for treating conditions such as aneurysms and arterial blockages.

Unlike traditional surgery, endovascular surgery involves inserting a catheter (a thin, flexible tube) into a blood vessel, typically through a small incision in the groin. Using real-time imaging guidance, the catheter is navigated to the treatment area. Once there, various tools attached to the catheter can be used to treat the condition. For example, in the case of an aneurysm, a stent or coil may be deployed to reinforce the blood vessel wall and prevent rupture.

The advantages of endovascular surgery include shorter recovery times, less pain and discomfort, reduced risk of infection, and typically a shorter hospital stay. However, not all conditions are suitable for this approach, and its feasibility largely depends on the specific situation and patient.

Vascular surgeons specialize in treating diseases of the entire vascular system, from arteries to veins and lymph nodes. These experienced specialists may use traditional open surgery or minimally invasive methods such as catheterization for diagnosis and treatment. In addition, they often collaborate with multidisciplinary teams on complex operations involving trauma cases requiring safe execution.

Peripheral Arterial Disease

Peripheral Arterial Disease (PAD) is a serious condition that affects 20% of adults over 65 worldwide, caused by atherosclerosis. This hardening of the arterial walls occurs when cholesterol accumulates on the inside and forms platelets, plaque deposits and tissue blockages which can restrict blood flow to extremities. These reduced amounts of oxygen-rich blood reaching legs often causes painful symptoms such as difficulty walking – leading in extreme cases to gangrene or amputation if left untreated.

What are the symptoms in Peripheral Arterial Disease:
Many older people associate peripheral arterial disease with ageing.

These problems should be discussed with your doctor, they are not related to the ageing process but to Peripheral Arterial Disease. An arterial Doppler examination in these circumstances is mandatory, so that the patient is on medication early and does not end up with more serious problems.

Population affected by Peripheral Artery Disease

From country to country, depending on lifestyle and dietary habits, Peripheral Arterial Artery Disease affects about 10% of the population. PAD can occur in anyone, but occurs in high percentages in the population over 50.

Venous Disease

What differentiates us from other clinics with a similar profile is a new approach, offering patients a medical service tailored to their specific needs, so that the treatment methods offered by Venart are tailored to the specific pathology of each patient. These include the Radiofrequency, Venosteam® steam method, laser varicose vein treatment, Alpha method and sclerotherapy.

Methods of treating Venous disorders in the VenArt clinic:

Varicose vein treatment with radiofrequency
Laser varicose vein treatment
Alpha method
Vena-Block vein treatment

Varicose vein disease affects about one third of the population and generally affects the great saphenous vein or the small saphenous vein in 30 to 50% of cases. Although the risk of developing varicose veins increases with age, 15% of the population under 40 is affected.

Venous diseases are treated according to their nature, the stage of the disease and the patient’s condition. The most appropriate and effective treatment is recommended by the specialist.

The affected veins are closed using radiofrequency waves. Radiofrequency provides controlled heat energy. The temperature at the vascular wall gradually increases. Radiofrequency (varicose vein surgery) can occlude a large size of a vein within seconds. The advantages are also multiple: minimally invasive method, minimal discomfort, incredible functional and aesthetic results, does not require hospitalization of the patient, leaves no scarring or inflammation, anesthesia is local, the patient can resume activity the next day.

Steam method - Venosteam

This innovative method effectively treats varicose veins, successfully replacing the traditional method of stripping. Varicose veins are closed by the heat released by steam vapour introduced into the affected vein via a catheter. This catheter is flexible and does not exceed 1.2 mm in diameter. The advantages of Venosteam include: minimally invasive surgery, short recovery time of 24-48 hours with resumption of daily activities on the 2nd day after surgery, no scarring, minimal or no post-operative pain, and last but not least, patients do not require hospitalization. The Venosteam method can also treat very large (dilated) and tortuous varicose veins. Venosteam treats all types of varicose veins.

Endovenous Laser treatment

Laser technology is used to quickly and effectively close damaged veins, allowing blood to be redirected through healthy pathways. This minimally invasive procedure does not require general anaesthesia yet ensures immediate return of normal activity after the session with only moderate post-operative discomfort occurring on occasions that can be treated easily by painkillers or anti-inflammatories for a maximum of five days.

Alpha method

Rather than using traditional sclerotherapy for larger varicose veins, this procedure utilizes a unique approach that relies on injecting sclerosing foam directly into the vein with precision and accuracy. Under ultrasound guidance, each step of the process is done to ensure maximal efficacy in treating these troublesome symptoms.

The advantages of the Alpha method are numerous: the procedure is precise, it has a high success rate and is considered a non-invasive treatment for varicose veins, there is no scarring, no hospitalisation is required, and the patient can resume daily activities from the next day.

Using a sclerosing substance, an experienced specialist can swiftly and painlessly close troublesome veins on an outpatient basis. The chemical-induced irritation swells the vein walls until it is completely shut – all within minutes! Safety assured with no need for hospitalization or anesthesia.

Vena-Block - Vascular Glue

Treatment of varicose veins with glue/vascular adhesive has been used in the United States for more than 12 years and in Europe for 8 years. However, the cost of the necessary supplies, as with any new technology, was quite high in the early years, which did not allow the technique to be used more widely until recently. However, this issue has been resolved in the meantime and allows us to offer patients this effective and non-aggressive method of treatment for cases where it is applicable.


  • Local anaesthesia;
  • Immediate return to work;
  • No post-procedure haematoma;
  • Very good aesthetic result;
  • Can be performed without interrupting anticoagulant treatment, for patients undergoing such treatment.
