Aim — the objective of the present study was to elucidate the tendencies in the development of the surgical treatment of primary varicose veins of the lower extremities (PVVLE) in the residents of a large industrial city during the past 5 years. Material and methods. We undertook the analysis of the statistical data on the patients presenting with PVVLE and operated in a round-the-clock clinic of Ekaternburg during the period from 2009 to 2013. In addition, similar data concerning the patients with the same pathology treated at an outpatient basis in the periods between 2005 and 2007 and from 2011 to 2013 were available for analysis. Results. The total number of conventional phlebectomies performed annually varied from 1627 to 1957 (mean 1815±165). The number of open interventions for the treatment of primary varicose veins showed no tendency toward a decrease for the  last 5 years. One third of the patients presenting with PVVLE have undergone the  surgical treatment based at the departments of general surgery. The number of sclerotherapeutic (CT) procedures increased and reached11,777 (or 80.4% of all ambulatory interventions performed in the  medical centers (MC) in 2013. The number of endovasal thermal obliterations in 2013 amounted to 2585; 74.6% of them were laser-assisted procedures. The number of minimally invasive phlebectomies performed based at one-day clinics was 340 per year. The number of surgical interventions for the treatment of decompensated or complicated cases of primary varicose veins did not decrease. Traditional phlebectomy performed in a round-the-clock clinic was followed by a 40 day-long (on the average) period of incapacity for work. On the city-wide scale, the number of inability-to-work days amounted to 72,600 per year. The one-day clinics were more efficacious in this respect even though the total period of incapacity for work after surgery based at these facilities was as long as 7,400 days per year on the city-wide scale. It is concluded that the ambulatory interventions for the treatment of primary varicose veins during the last three years made it possible to save for the city 304,400 productive work days.
