Key points

  • A phlebology clinic is a medical centre focused on vein disorders: varicose veins, spider veins and venous insufficiency.
  • Phlebology is part of angiology and vascular surgery; the right specialist is a doctor board-certified in that speciality.
  • A good centre first performs a diagnostic Doppler ultrasound and then proposes treatment (laser or radiofrequency, sclerotherapy, cyanoacrylate, surgery, etc.).

If you have varicose veins or spider veins and are looking for somewhere to treat them, it is easy to get lost among the names. Phlebology clinics advertise with very different hooks and not all of them offer the same thing. Here, in plain language, is what phlebology is, what varicose vein treatments exist and what to look for so you can choose with sound judgement.

What is a phlebology clinic?

A phlebology clinic is a medical centre focused on the study and treatment of vein disorders, above all those of the legs: varicose veins, spider veins and venous insufficiency. Phlebology is the part of vascular medicine that deals with the venous system, and it should be led by a medical specialist.

The term 'phlebology' describes a field of work, not an official qualification in Spain. That is why it is worth looking beyond the name of the centre and paying attention to who treats you and with what training.

Phlebology, angiology and vascular surgery

Phlebology deals with the veins. Angiology and vascular surgery is the medical speciality that covers the whole circulatory system except the heart, the ascending aorta and the intracranial vessels: arteries, veins and lymphatic vessels. In other words, the veins are one part of the ground the vascular specialist covers.

In Spain, Angiology and Vascular and Endovascular Surgery is the recognised speciality obtained through the MIR training route. There is no separate official speciality called 'phlebology'. That is why, when you are looking for somewhere to treat your varicose veins, the sensible reference point is a board-certified doctor specialising in Angiology and Vascular Surgery, who can diagnose, treat and operate if needed.

This matters because varicose veins are not always an isolated problem. Sometimes they are the visible part of venous insufficiency that is worth studying as a whole. You will find the detail on the page about varicose veins and venous insufficiency.

Dr. Vicente Mosquera Rey

Before we talk about laser or surgery, we need to map the veins with a Doppler ultrasound. Choosing well is not about looking for the treatment that is in fashion; it is about picking the right treatment for each patient and their anatomy.

What varicose vein treatments they offer

There is no single treatment for varicose veins. The right technique depends on the type of vein affected and on what the examination shows. These are the options a phlebology clinic usually handles, explained in plain terms:

TechniqueWhat it is for
Endovenous laser or radiofrequencyThey close the saphenous veins that are insufficient 'from the inside', using heat. They are minimally invasive techniques performed through a catheter.
CyanoacrylateAn adhesive method that polymerises on contact with the blood and also closes the saphenous veins from within. It is minimally invasive.
SclerotherapyInjects a product that scleroses small and medium-sized veins, such as reticular veins and spider veins.
SurgeryRemoves the affected veins with surgical techniques or focally disconnects the points of reflux. It is reserved for specific cases, when the anatomy is not favourable for minimally invasive procedures.
Baseline measuresCompression stockings, physical activity, postural measures and weight control. They accompany the treatment and help with symptoms.

No technique is 'the best' in the abstract: the good one is the one that fits each case. That is why what matters is not which device the centre has, but choosing the most suitable technique for the patient and their anatomy after mapping it with a Doppler ultrasound.

How to choose well: what to look for

These are the points worth reviewing before you decide:

  • Who treats you. That it is a board-certified doctor specialising in Angiology and Vascular Surgery. You can check the professional's registration and training.
  • Doppler ultrasound before treating. A good centre usually performs an ultrasound of the veins to see what is failing before proposing anything to you. Without a diagnosis there is no tailored treatment.
  • That they explain the risks. Every procedure has advantages and limits. An honest professional also tells you about the possible complications associated with each technique and the alternatives.

If you want a local reference, you can have your case assessed by a vascular surgeon in Madrid and compare what they propose against these criteria.

In summary

A phlebology clinic treats vein disorders. Look for a board-certified specialist in Angiology and Vascular Surgery who starts with a Doppler ultrasound and explains which technique is best in your case and the possible complications involved. With those criteria, the decision no longer depends on the advertisement and comes to depend on your diagnosis instead. If you have varicose veins and doubts, the most sensible step is an assessment with a vascular specialist.

Frequently asked questions

What is the difference between a phlebologist and a vascular surgeon?

Phlebology is the branch of medicine that studies the veins. In Spain it is not a separate official speciality: the person who treats veins on sound medical grounds is the specialist in Angiology and Vascular Surgery. That qualification, together with being registered with the medical board, is the reference to look for.

Do you need a Doppler ultrasound before treating varicose veins?

Yes. The Doppler ultrasound is a scan that shows how blood flows through your veins and where the problem lies. Without that information the treatment cannot be chosen properly. It is a painless test and should be done before anything is proposed to you.

Does a phlebology clinic treat spider veins?

Spider veins on the legs do fall within venous disease and are assessed together with the rest of your circulation. Spider veins on the face are a matter of facial aesthetics and are the domain of dermatology.

Who is the 'vein doctor'?

The 'vein doctor' is the angiologist and vascular surgeon: the specialist who diagnoses and treats varicose veins, venous insufficiency and thrombosis. They are the one who performs the Doppler ultrasound and decides on the most suitable treatment for each case.
