Ultrasound can assess the condition of deep and superficial veins of the leg. It can detect diseases and conditions that cause swelling and pains in the legs. A frequent condition is chronic venous insufficiency which shows in the form of varicose veins, swollen ankles, skin reactions, and venous leg ulcer in more severe cases.
The scan first focuses on the deep veins of the leg and detects their patency. It can establish whether blood clots are present in the deep veins. Veins with poor patency resulting from venous thrombosis may cause severe cases of chronic venous insufficiency. The ultrasound scan of superficial veins is necessary if we decide for more invasive treatment: varicose vein surgery, and before thermal intravascular closure of major trunks of superficial veins by laser or radio frequency energy. The examination precisely shows the reflux in superficial vein trunks.
Preparation for examination
No preparations are required for the examination.
The patient lies on the table in the course of deep vein examination. Superficial veins are examined with the patient in a standing position.
