Risk factors of the development of phlebothrombosis and thromboembolism of the pulmonary artery (TEPA) were estimated in 257 patients as associated both with the patient and the trauma. The factors influencing the development of risk factors were: bed immobilization, age older than 40, heart failure and respiratory insufficiency, fractures of the lower extremities, skeleton traction, obesity, thrombosis of lower extremities, previous thrombosis or pulmonary embolism, floating clot. Risk factors of the development of vein thrombosis associated with trauma included the presence of lower extremity fractures, skeletal traction or immobilization in bandage, mechanism of injury and type of trauma.

The study accrued 257 patients with mechanical traumas of varying severity and sites, complicated by post-traumatic phiebothrombosis. In 87 (33.85%) patients, traumatic disease was aggravated by pulmonary artery thromboembolism (PTE). In the course of the study we evaluated risk factors of PTE related to the patient's condition and trauma. It has been established as a result that of 14 recognized risk factors of PTB determined by the patient's condition, only six influenced this disease outcome, namely: age over 40 years, a history of PTE or deep venous thrombosis (DVT), overweight, circulatory and respiratory insufficiency, bed regime. Among risk factors of PTE linked with trauma, the following factors had a significant impact on the emergence of PTE: treatment by means of skeletal traction, the site of trauma in the lower extremity (femoral or tibial bone), the site of previous thrombosis in the deep veins of the leg and thigh as well as floating thrombus.

A total of 100 patients with varicosis of lower limb veins were investigated with the help of distal ascending phlebography in horizontal, vertical and tilted positions. Considerable differences in x-ray images of musculi gastrocnemius and soleus (MGS) were noted. Four main types of MGS (conic, spindle-form, U-form, and balloon-like) were singled out. Correlation between muscular vein sizes and stages of varicosis was revealed. An important role of the pathology of muscular veins in dysfunction of the leg pump as one of the factors of pathogenesis of lower limb varicosis was confirmed.

The individual indications for applying four methods for valve correction in 241 patients with valvular incompetence of the deep veins were determined on the basis of a developed four-stage organization-diagnostic complex. The methods were as follows: correction with a lavsan spiral (70 operations), suturing with paravasal structures (59), three-ligature method (142), and an original method with shortening of the cusps without opening the vein (30 operations). Study of the late results in follow-up periods of 12 months to 7 years showed the latter method to be most effective (88.2%).
