Diagnosis of Varicose Veins of the Lower Limbs – Functional Tests ORIGINAL PAPER Arch Physiother Glob Res 2016; 20 (3): 29-32 Diagnosis of varicose veins of the lower limbs – functional tests Agnieszka Pedrycz ABCDEFG, Beata Budzyńska ABCDEFG Departament of Histology and Embryology, Medical University in Lublin, Poland Abstract Varicose veins of the lower limbs are dilated, gnarled, swirled and twisted superficial veins with balloon -like bulges. They are divided into two types – primary varicose veins with normal deep veins and secondary ones which develop after trauma or superficial phlebitis. They form in various locations, e.g. on the great saphenous vein, accessory posterior and anterior saphenous vein and small saphenous vein. Present study presents functional tests used in diagnosis of variose veins. Key words: varicose veins, functional tests Symptoms and causes sence of valves in the superficial veins. When a Primary varicose veins are caused by a decrease of valve is not present or cannot close completely, the the elastic tissue amount in venous walls, which be- blood carried to the heart flows partly backward. come less stretching-resistant. The dilation of venous It accumulates in the veins and increased pressure walls leads to valve failure resulting in backward flow stretches the veins leading to the development of and accumulation of larger amounts of blood and varices [7]. contributes to further dilation of vessels.

Varicose veins are extremely rare in children from valve malfunction in the perforator and deep whereas their incidence in 60-year-olds individuals is veins [2, 3, 4]. sixfold higher, compared to 30-year-olds.

A high probability DVT Wells score was found. No clinical signs or symptoms of PE were observed and CT scan excluded it. D-dimer test was 10.21 and venous ultrasonography confirmed the diagnosis of extensive DVT and thrombi from the popliteal up to the external iliac veins. Following our guideline, Bemiparin was immediately administer and was continued until optimal INR range was achieved acenocoumarol (4 days after being discharged home). Good outcome was observed over a 2 years follow up period. Despite the severity and magnitude of the DVT this patient did not develop PE with Bemiparin treatment, as he previously did with heparin.
