Reticular veins overview
Reticular veins are small superficial veins noted on the surface of lower extremities; in the spectrum of superficial venous disease, they are smaller than varicose veins but larger than spider veins. Using the venous disease classification, reticular veins are part of group 1 (CEAP 1), indicating a mild form of venous disease.
What causes reticular veins?
Reticular veins are caused by an abnormal dilatation of the superficial veins under the skin. Risk factors for vein dilatation include: advancing age due to reduced vein wall elasticity, previous vein surgery, prolonged sitting or standing, obesity, pregnancy and immobility.
Symptoms of reticular veins
Patients may be entirely asymptomatic or may experience lower extremity discomfort, burning, itching related to reticular veins.
Patients may report cosmetic concerns related to the presence of reticular veins; these veins are about 2mm in diameter and their color varies from green-bluish to purple.
Diagnosis of reticular veins
A detailed medical history is obtained followed by a focused physical examination to evaluate the lower extremities for the presence and extent of venous disease. Reticular veins may be associated with a more advanced form of superficial venous disease; if more serious superficial vein disease is suspected, a vascular ultrasound may be recommended.
How are reticular veins treated?
Conservative management is advisable for the majority of patients.
For patients who are symptomatic or who have cosmetic concerns, there are treatment strategies to eliminate the trouble veins. These non-surgical techniques include sclerotherapy and laser.
