Reticular veins
back to main page
Reticular veins are superficial dilatations of intradermal veins, usually 1 to 3 mm in diameter, visible through the skin as a purple or bluish network of vessels. They represent an intermediate form between small telangiectasias (so-called spider veins) and classic varicose veins of the lower limbs. They are most commonly located on the thighs, lower legs, and in the popliteal fossa area. These lesions are chronic in nature and are associated with superficial venous insufficiency, although in many cases they remain primarily an aesthetic problem. However, their presence may indicate hemodynamic disorders requiring further phlebological diagnostics.
Reticular veins – what they look like
Reticular veins take the form of thin, tortuous, or straight vessels visible through the skin. Their characteristic feature is an arrangement resembling a net or a branched structure, from which their name originates.
The most important morphological features include:
- diameter of 1–3 mm – larger than in the case of telangiectasias, but smaller than in classic varicose veins,
- livid, blue, or purple color, resulting from the presence of deoxygenated venous blood,
- intradermal or subcutaneous localization,
- irregular vessel course, often forming extensive networks.
Most common sites of occurrence:
- lateral surfaces of the thighs,
- popliteal regions,
- medial parts of the lower legs.
Unlike large trunk varicose veins, reticular veins usually:
- do not cause significant skin bulging,
- are less frequently palpable,
- more often coexist with telangiectasias as so-called "feeder veins."
In clinical practice, they are considered an element of the chronic venous disease (CVD) spectrum, most commonly classified as stage C1 on the CEAP scale.
Reticular veins – are they dangerous
Reticular veins can remain asymptomatic for a long time and be perceived solely as an aesthetic defect. However, their presence may indicate functional disorders of the venous system, and therefore they require a proper assessment.
Potential accompanying symptoms:
- feeling of heavy legs,
- tension and discomfort within the lower limbs,
- burning or itching of the skin,
- slight swelling, intensifying at the end of the day.
The clinical significance of reticular veins includes:
- indication of venous valve insufficiency, especially in the superficial venous system,
- association with telangiectasias – they often serve as feeding vessels for small „spider veins”,
- risk of venous disease progression, especially in the presence of predisposing factors.
Risk factors include:
- genetic predisposition,
- prolonged standing or sitting,
- pregnancy and hormonal changes,
- obesity,
- lack of physical activity.
Complications occur rarely; however, in advanced cases, they may include:
- development of larger varicose veins,
- chronic venous insufficiency,
- skin microcirculation disorders.
From a phlebological point of view, ultrasound diagnostics (Doppler US) is of key importance, as it allows for the assessment of:
- patency of the venous system,
- presence of reflux (backflow of blood),
- the relationship between reticular veins and the deep system.
Reticular veins – treatment
Treatment of reticular veins is selected individually and depends on the severity of the lesions, symptoms, and the results of imaging diagnostics. Management includes both conservative and procedural methods.
1. Conservative management
In the early stages of the disease, the following are recommended:
- compression therapy (compression products with an appropriately selected degree of pressure),
- lifestyle modification:
- regular physical activity (e.g., walking, swimming),
- avoiding prolonged standing and sitting,
- weight reduction,
- phlebotropic pharmacotherapy (e.g., diosmin, hesperidin), supporting venous wall tone.
2. Sclerotherapy
One of the most commonly used treatment methods:
- involves injecting an obliterating substance (sclerosant) into the vessel lumen,
- leads to controlled closure of the vein and its gradual disappearance,
- can be performed as:
- liquid sclerotherapy,
- foam sclerotherapy.
Advantages:
- high effectiveness in the case of reticular veins,
- minimal invasiveness,
- short recovery time.
3. Laser therapy and light technologies
Modern methods using light energy:
- vascular laser (e.g., Nd:YAG) – selective photothermolysis of hemoglobin leading to vessel closure,
- IPL (intense pulsed light) – broadband light used in the treatment of minor vascular lesions.
Mechanism of action:
- energy absorption by hemoglobin,
- damage to the vessel wall,
- gradual resorption of the lesion.
4. Supplementary methods used in clinical practice
In comprehensive therapy, available in modern centers, the following are also used:
- laser vessel closure procedures,
- combined therapies (e.g., sclerotherapy + laser therapy),
- technologies supporting microcirculation and skin regeneration.
As part of the Ambasada Urody Clinic & SPA offer, the following are used, among others:
- laser vessel closure – precise removal of vascular lesions,
- sclerotherapy – the standard in the treatment of reticular veins,
- combined therapies improving aesthetic and functional effects.
5. Treatment effects and prognosis
Therapy effects include:
- reduction in vessel visibility,
- improvement of skin aesthetics,
- reduction of subjective symptoms (leg heaviness, discomfort).
The prognosis is very good; however, the following must be taken into account:
- the possibility of recurrence (the disease is chronic),
- the necessity of prevention and follow-up,
- the importance of causal treatment (e.g., venous insufficiency).
