Our unit

Personal, rigorous, evidence-based vascular care

Our Angiology, Vascular and Endovascular Surgery Unit at Centro Médico Teknon specialises in the comprehensive diagnosis, treatment and follow-up of diseases of the arteries, veins and lymphatic system.

In consulting room 10 we offer a specialised, personalised vascular assessment, with medical treatment, conventional vascular surgery and minimally invasive endovascular procedures.

  • Aortic disease treated with open surgery and endovascular techniques
  • Prevention of stroke related to carotid disease
  • Treatment of circulation problems in the legs
  • Preventive vascular screening and cardiovascular risk assessment

Especially for patients with high blood pressure, diabetes, high cholesterol, a smoking habit, previous cardiovascular disease or a family history of vascular disease.

Specialised units

A dedicated team for every vascular condition

We study each case individually to choose between medical treatment, minimally invasive techniques, endovascular surgery or open surgery.

Vascular check-up and prevention

Individual vascular risk assessment and early detection of arterial disease before complications appear.

Learn more

Varicose veins and venous insufficiency

Doppler ultrasound assessment and minimally invasive treatment: radiofrequency, laser, sclerotherapy, microfoam and phlebectomy.

Learn more

Peripheral arterial disease

Pain when walking, claudication and ischaemia: angioplasty, stenting, bypass and hybrid surgery.

Learn more

Aorta and aneurysms

Monitoring and repair of aneurysms with open surgery, EVAR, TEVAR and complex endovascular techniques.

Learn more

Carotid disease and stroke prevention

Diagnosis of carotid stenosis, endarterectomy and endovascular treatment to reduce the risk of stroke.

Learn more

Diabetic foot

Vascular assessment, revascularisation and a multidisciplinary approach to save the limb.

Learn more

Venous thrombosis

Thrombophlebitis, deep vein thrombosis and post-thrombotic syndrome: individual diagnosis and follow-up.

Learn more

Spider veins and reticular veins

Sclerotherapy and cosmetic vascular treatment after a prior assessment of the venous system.

Learn more

Pelvic venous disease

Pelvic congestion, May-Thurner and Nutcracker: embolisation and venous stenting in selected patients.

Learn more

Ulcers and complex wounds

We identify the cause of the wound and treat the vascular disease that prevents it from healing.

Learn more

Lymphoedema and leg swelling

Differential diagnosis of the swollen leg: lymphoedema, venous insufficiency and other causes.

Learn more

Second opinion

Specialist review of complex cases, imaging tests and vascular reinterventions.

Venous disease

Explore the stages of venous insufficiency

The CEAP classification describes the clinical signs of chronic venous disease, from legs with no visible signs to an active ulcer. Slide or tap each stage.

Leg at CEAP stage C0: No visible signs Leg at CEAP stage C1: Telangiectasias or reticular veins Leg at CEAP stage C2: Varicose veins Leg at CEAP stage C3: Oedema Leg at CEAP stage C4: Skin changes Leg at CEAP stage C5: Healed venous ulcer Leg at CEAP stage C6: Active venous ulcer

CEAP clinical classification

C0

No visible signs

No visible or palpable signs of venous disease.

CEAP describes the clinical severity of venous disease. It does not represent an inevitable progression.

Our values

How we approach vascular medicine

  1. 01

    Highly specialised vascular medicine

    Expert care for arterial, venous and aortic disease, from the most common problems to highly complex cases.

  2. 02

    Every patient, their own strategy

    We do not apply one-size-fits-all treatments. We assess each case to choose between medical treatment, minimally invasive techniques, endovascular surgery or open surgery.

  3. 03

    Technology guided by medical judgement

    We use the most advanced diagnostic and therapeutic techniques when they bring real benefit, avoiding unnecessary procedures.

  4. 04

    A complete view of the circulation

    We do not just treat a varicose vein, an artery or an aneurysm: we look at the vascular patient as a whole, including their risk factors.

  5. 05

    Prevention before complication

    Early diagnosis and preventive vascular care to reduce the risk of stroke, amputation, thrombosis and aortic complications.

  6. 06

    Solving complex cases

    Experience in aortic disease, advanced arterial disease, carotid problems and situations that call for multidisciplinary decisions.

  7. 07

    Minimally invasive whenever possible

    We prioritise endovascular procedures that reduce surgical trauma, ease recovery and maintain the highest level of safety.

  8. 08

    Genuine continuity of care

    We support patients from diagnosis through treatment and follow-up, especially in chronic vascular disease.

  9. 09

    Explain before we treat

    Patients should understand what condition they have, what the alternatives are and why we recommend a particular strategy.

  10. 10

    Technical excellence with a personal touch

    Highly complex medicine with an accessible, human doctor–patient relationship built on trust.
