As the global experience shows, the extension of the outpatient medical care is the most promising approach to the successful treatment of the patients suffering from varicose veins of the lower extremities. Aim of the study. To analyse the results of the treatment given to the patients with varicose veins of the lower extremities who were operated in an outpatient surgery centre, to estimate the volume of such aid in the structure of the municipal health service and prospects of its further extension. Material and methods. The analysis included the results of surgical treatment of 313 patients with varicose veins treated in an outpatient centre and of 794 in-patients of whom 236 (29.72%) ones were excluded from the study. Exclusion criteria were the presence of concomitant pathology requiring constant round-the-clock observation under the in-patient conditions, forms of primary varicosis the treatment of which is impossible by the methods available in a day surgical facility. The reference group was comprised of 558 (70,28%) in-patients who could be treated in the outpatient centre. Results. Four (1.28%) patients treated in the outpatient centre and 9 patients (1.61%) admitted to the in-patient hospital developed complications during the immediate postoperative period. The average duration of temporary disability in the ambulatory patients was 11,5±1,14 days in comparison with 26.7±4,7 days in those operated in the in-patient hospital. 287 (91.7%) patients of the outpatient centre and 412 (73.84%) in-patients did not suffer complications during the follow-up period from one to three years in duration. Conclusion. The analysis of the effectiveness of the treatment of the patients with uncomplicated varicose veins of the lower extremities in the absence of concomitant pathology showed that the outcomes of their treatment in the outpatient centre were identical with the results of the treatment given in the in-patient hospital. However, the results of the outpatient treatment surpassed those of the in-patient treatment in terms of duration of temporary disability and rehabilitation. This fact justifies planning the further extension of phlebological aid based at the outpatient facilities and makes possible the enhancement of its cost effectiveness by providing expensive in-patient beds for 70% the patients with varicose veins of the lower extremities.
