Karpenko K. The use of mini-invasive technologies in the complex treatment of patients with post-thrombotic disease of the lower extremities

The dissertation is devoted to an actual scientific problem - surgical treatment of patients with post-thrombotic disease of the lower extremities. Post-thrombotic disease is a chronic venous pathology associated with acute deep vein thrombosis (DVT). The name "post-thrombophlebitic syndrome" is found in literary sources of the countries of North America and the countries of the European Union. Postthrombotic disease of the lower extremities (PTDLE) is a pathology caused by further pathomorphological and pathophysiological processes in the venous system. Although the pathogenesis of PTDLE is complex and closely related to deep vein thrombosis and previous deep vein thrombosis, the central role is played by venous hypertension (hydrostatic blood pressure between the right atrium and the foot), PTDLE is detected in 5-7% of the working population of developed countries and up to 28% from patients with various types of venous pathology. PTDLE is the most common long-term complication after deep vein thrombosis that occurs in a limb. In most cases, PTDLE develops from several months to several years after a DVT and is from 1 to 3 per 1000 people in the general population. Operative intervention on the venous system in patients with PTDLE is a difficult stage in complex treatment. Modern operative interventions provide maximum cosmetic effect and complete radicalism regarding the causes of occurrence, differ in methods, techniques and tools. The introduction of mini-invasive technologies and the technology of electric welding of living tissues in the complex treatment of patients with PTDLE is relevant, reducing the duration of inpatient treatment, the severity of the course of the disease, and the risks of complications. The purpose of the study: to improve the results of treatment of patients with PTDLE, through the optimal choice of methods and volumes of surgical interventions based on anatomical and hemodynamic types of the disease and the use of minimally invasive technologies, including new ones implemented based on developed surgical tools.
