INTRODUCTION According to the definition of the World Health Organization, varicose veins represent abnormally enlarged superficial veins having baggy or cylindrical shape. The most frequent cause of primary varicose veins is the insufficiency of long saphenous vein (LSV), but especially the basin of its connection with femoral vein and perforating veins. OBJECTIVE The objectives of these investigations were: the determination of insufficiency incidence of SSV in cases of LSV insufficiency; the establishment of association of insufficiency of perforating veins of the basin of LSV and SSV; the study of the results of surgical treatment of insufficiency and varicosity of both short and long saphenous veins. METHODS In this study, 100 patients (66 women and 34 men), average age 52.1 years, with clinical symptoms showing the insufficiency and varicosity of long saphenous vein with no change of deep vein system were examined. Ultrasonographic examinations were made using Color Doppler probes - 7.5 and 3.75 MHz (Toshiba Corevison SSA 350 A); the development of incompetence of long saphenous vein (LSV) and short saphenous vein (SSV) at the level of the junction as well as other incompetent valves were examined. The reflux was defined as a retrograde flow of the duration longer than 0.5 seconds. RESULTS The insufficiency of short saphenous vein was determined by ultrasonographic examination in 34%, while the insufficiency of perforating veins in 80% of patients. 40% of patients were operated (33.3% of females, and 52.9% of males). The most frequent indications for surgical treatment of superficial veins insufficiency were: strong varicosities, clear symptoms and signs, superficial thrombophlebitis and conditions after superficial thrombophlebitis. Surgical treatment was applied in 16% of patients due to recurrence in the basin of long saphenous vein, and in 6% of cases because of the recurrence in the basin of short saphenous vein. Data analysis failed to discover any statistically significant difference between the age of patients and varicosities in the basin of long saphenous vein as well as in the basin of short saphenous vein (51.98?9.97 years; 54.50?31.82 years; t=0.36; p>0.05), or any significant difference of BMI value, with regard to the obesity of patients and varicosities in the basin of long saphenous vein as well as in the basin of short saphenous vein (28.02?4.61 kg/m2; 24.50?6.36 kg/m2; t=0.50; p>0.05). No statistically significant correlation was found between Color Duplex findings of insufficiency of both long saphenous vein and short saphenous vein (p=-0.21 ; p>0.05), nor any significant correlation of Color Duplex findings of perforating veins insufficiency in the basin of long saphenous vein and short saphenous vein (p=-0.115; p>0.05). CONCLUSION The incidence of insufficiency is significant: approximately every third patient has short saphenous vein insufficiency, while three third of patients have perforating veins insufficiency. Color Duplex limb's veins ultrasonography is highly reliable method for the examination and study of superficial veins diseases, which is very important for preoperative decision-making and selection of surgical technique as well as for postoperative follow-up.
