Nowadays most issues regarding venous disorders are described as chronic venous insufficiency (CVI)-which is defined as all symptoms that manifestate as impaired blood outflow from the lower limbs or in general the result of blood stasis in the deep and superficial venous system. Due to the fact that the symptomatology of venous diseases is wide, the treatment should be multioriented and often as well multi-specialized. The treatment of CVI needs a good understanding of the etiology of the primary insufficiency of the superficial and the deep venous systems. The main purpose of the surgical therapy is to remove the reflux in the great saphenous vein and the perforating veins. Additionally, during the surgical treatment the various veins should be removed in a way that gives the best cosmetic effect. In this article we presented the analysis of different surgical treatments in patients diagnosed with CVI 2-4 grade according to CEAP scale. The patients were hospitalized in our Clinic between april 1998 and april 2003. This group consisted of 311 patients, among them were 257 patients with primary varices, 25 patients with recurrent varices and 29 with postthrombotic syndrome. The choice of surgery was based on clinical examination and the result of venous USG. The most frequent (62%) surgical therapy was removal of the great saphenous vein with miniphlebectomy. To make the treatment more efficient we used the endoscopic method of obliteration of the insufficient perforating veins in lower limbs, called subfascial endoscopic perforating surgery (SEPS).
