Aim: To develop of a new complex of conservative techniques that eliminate clinical manifestations of chronic venous insufficiency, preserve the ability to work and improve the quality of life of patients, being the main method of preoperative preparation and postoperative rehabilitation in some patients. Materials and Methods: The article describes clinical and practical recommendations for the diagnosis and treatment of patients with chronic venous insufficiency (CVI) and post-thrombophlebitic syndrome (PTS) of the lower extremities. The treatment of these pathologies should take into account the variability and combination of symptoms, comorbidities, as well as the patient’s work activity and socioeconomic factors that may affect the modification of classical treatment regimens. Results: The examination and treatment of patients with this pathology has been carried out at the surgical department of the Poltava Central District Clinical Hospital since 2019 year. On the basis of a complex ultrasound examination with the determination of reflux in the deep and superficial veins of the lower extremities and horizontal reflux in the perforating veins, patients were divided into two groups. The first group consisted of 28 (57.1%) patients with superficia and the second group of 16 (42.9%) patients with deep venous hypertension. Conclusions: The main component of the conservative treatment of this pathology (CVI and PTS) is compression therapy, venotonics, medicines that improve microcirculation in the affected tissues, laser therapy, salves and gels were used locally, depending on the phase of the wound process, in case of trophic changes.
