Treating varicose veins isn't simply a matter of choosing between laser and surgery. A visible vein can be primarily a cosmetic concern, a symptom of venous disease, or a sign of a more advanced condition. Clinical examination and Doppler ultrasound are used to identify the affected vein network, the direction of blood flow, and the presence of reflux before any treatment is recommended.
This guide presents the main options without establishing a universal ranking. Sclerotherapy, endovenous laser ablation, radiofrequency ablation, phlebectomy, and stripping are used in different situations. The choice depends on the anatomy, symptoms, medical history, patient preferences, and the team's experience.
When should I seek medical advice for varicose veins?
Medical advice is recommended when veins become painful, feel heavy, itchy, swollen, or show signs of skin changes. A hard, tender vein, leg eczema, a persistent wound, or the recurrence of varicose veins after treatment also warrants evaluation. The external appearance alone is insufficient to determine the severity of venous reflux.
Bleeding from a varicose vein requires prompt medical attention. Sudden calf pain, asymmetrical swelling, shortness of breath, or chest pain also warrant urgent consultation to rule out thrombosis or embolism. If you experience severe symptoms or feel unwell, contact emergency services.
What venous Doppler ultrasound shows
Doppler ultrasound is a non-invasive examination that visualizes veins and studies blood flow. It helps confirm reflux, identify the affected trunks and branches, detect obstructions, and prepare for potential treatment. It is particularly important before treating symptomatic, recurrent, or varicose veins associated with skin complications.
The report is not simply a list of veins "to be removed." The vascular physician relates the images to the patient's discomfort, history of thrombosis, arterial status, current treatments, and goals. Therefore, two people whose legs appear similar may receive different recommendations.
Symptomatic measures and the role of compression
Appropriate physical activity, limiting periods of inactivity, and managing aggravating factors can help with certain symptoms. These measures will not eliminate existing reflux. They are part of a strategy developed with a healthcare professional, particularly when interventional treatment is not indicated or must be postponed.
Compression stockings are a medical device, not a routine purchase. Their indication, type, level, and duration must be determined after evaluation. The healthcare professional will specifically check arterial circulation, as certain arterial conditions constitute a contraindication or require precautions. The size and fit also influence tolerance. After a procedure, compression instructions vary depending on the technique and the situation: you should not automatically follow the regimen of a relative or a previous treatment.
What techniques can be proposed?
Sclerotherapy
Sclerotherapy involves injecting a product into a targeted vein to cause it to close. The procedure can be guided by ultrasound. It is used for certain varicose veins, but is not suitable for every anatomy or medical profile. The specialist checks for contraindications and explains the possible side effects, including local reactions, pigmentation, venous inflammation, and, more rarely, thromboembolic or neurological complications.
Endovenous laser and radiofrequency
These techniques involve inserting a catheter into the vein under ultrasound guidance. Thermal energy then closes the treated segment. Guidelines often place them among the preferred options when trunk reflux is confirmed and the anatomy is suitable. However, they are not an automatic choice: the vein's course, its tortuosity, its proximity to the skin or certain nerves, as well as the patient's medical history, can all influence the decision.
Hematoma, pain, sensory disturbances, skin burns, inflammation, or thrombosis are among the risks to be discussed. The procedure, anesthesia, monitoring, and permitted activities are organized by the team. Outpatient care or a quick return to work should not be promised before this evaluation.
Phlebectomy
Phlebectomy involves removing small sections of superficial veins through short incisions. It may be performed alone for certain branches or in conjunction with treatment for primary reflux. Its suitability depends on the distribution of the varicose veins and the desired outcome. Bruising, local discomfort, altered sensation, infection, or delayed healing are all possible side effects.
Stripping or deveining
Stripping surgically removes a diseased saphenous vein. Its use has become less frequent with the development of endovenous techniques, but it remains an option when these are unsuitable, unavailable, or undesirable. The procedure may be combined with other interventions. The risks associated with anesthesia, wounds, nerve damage, bleeding, and thrombosis must be discussed in the informed consent form.
How is the choice individualized?
- location and extent of reflux on Doppler ultrasound;
- diameter, path and accessibility of the veins concerned;
- symptoms, skin condition and possible presence of an ulcer;
- history of thrombosis, arterial condition and associated diseases;
- ongoing treatments, pregnancy plans and mobility;
- Informed preferences after discussion of benefits, constraints, and uncertainties.
Comparative trials show that several techniques can improve symptoms and quality of life in selected patients, with varying outcome profiles and limitations. They do not demonstrate that any one method is suitable for everyone. New varicose veins may appear and reflux may recur, even after a technically successful procedure.
Follow-up, monitoring and warning signs
Post-treatment instructions depend on the procedure, the type of anesthesia, the patient's occupation, their general health, and their progress. The team will specify local care, permitted walking and activities, any compression therapy required, prescribed treatments, and the follow-up appointment. Our guide to home recovery after surgery can help organize documents and contacts, but the instructions provided remain the primary focus.
Any pain or swelling that increases, a very red or hot leg, persistent bleeding, an open wound, fever, shortness of breath, or chest pain should be reported immediately. Moderate postoperative swelling may occur, but it should not be interpreted in isolation: the information sheet on postoperative edema and its warning signs reminds you when to seek medical advice.
Venous ulcers and other specific situations
A venous ulcer requires coordinated management of both the wound and the venous disease. Some studies support earlier treatment of superficial reflux in patients with ulcers, but these findings do not apply to all varicose veins. Pregnancy, arterial disease, a history of thrombosis, or reduced mobility also alter the assessment.
Healthcare in France: questions to ask
Reimbursement depends on the indication, the procedure performed, the practitioner's sector, the care pathway, and your supplemental health insurance contract. Request a quote when available and verify the conditions with the national health insurance (Assurance Maladie) and your supplemental insurer. Regarding returning to work, the duration of any potential leave is determined based on the procedure and the job; our article on sick leave after surgery explains the general procedures.
