The work deals with the description of methods for phlebography of the lower extremities with the patient in a vertical pos position with the use of various functional, loading, and pharmacological tests. Such examination makes it possible to recognize the pathological changes, reveal precisely the architectonics of the venous system and the localization of the most changed areas of the venous system, and determine the rate of the venous blood flow. Much attention is paid to preventive measures during phlebographic examination. The efficacy of the phlebography method is proved on a rich clinical material and the indications and contraindications for it are specified.
The results are analyzed for 30 surgical interventions on the legs for chronic venous insufficiency. Feasibility is considered of surgical correction of the function of the deep vein valvular apparatus, of retrograde circulation arrest by obturation of posterior tibial veins in varicosity and postthrombotic diseases.

The author suggests an original and novel method for the surgical treatment of post-thrombotic hypodermatitis, which involves, in association with the elimination of all long reflux vessels, the incision of the skin along the healthy edge of hypodermatitis. This is followed, after the elimination of short reflux vessels from the sub-fascial compartment, by the taking of pieces of sub-fascial aponeurosis which ensure drainage of the hypodermis. After one year, 7 of 12 patients were apparently totally cured. After 2 years, only 2 patients still had slight signs of hypodermatitis. At the present time, patients are followed up with elastic compression of moderate intensity.
The present work describes the results of an all-round examination and treatment of 120 patients suffering from different forms of chronic venous insufficiency (CVI) of the lower extremities with trophic disorders of soft tissues. Of these, varicosis was present in 91 (75.8%) patients and postthrombotic disease - in 29 (24.2%), patients. Hemomicrocireulation was examined by laser Doppler flow-metry. Assessment was made of the functional activity of neutrophilic granulocytes of the microcirculatory bed. The data were obtained indicating the decrease of skin perfusion and activation of neutrophils in the hemomicrocirculatory bed of the involved extremity at venous outflow decompensation. Of the 120 persons, conservative treatment was provided to 23 patients, in 45 patients, the conservative measures represented a stage in the preoperative preparation. Ninety-seven patients were operated on. The studies of hemomicrocirculation carried out at different times after treatment have demonstrated that conservative treatment produces a beneficial effect on hemomicrocirculatory disorders in the lower extremities of patients with CVI. However, the effects of conservative therapy are unstable and not long-lasting. Surgical correction of the venous outflow in patients with decompensated forms of CVI of the lower extremities leads to a stable improvement of the functional parameters of microcirculation.

A new technique has been worked out for intravasal autovenous valvuloplasty. It is based on the "ink-pot that does not spill" principle with creation of two cusps and is used in the treatment of patients with post-thrombophlebotic disease of the lower limbs induced by absolute valvular incompetence of the great veins. Criteria are offered for assessment of the efficacy of the technique for formation of venous valves. Altogether 54 operations were performed including those provided to 29 patients (the main group) operated on according to the technique proposed and those in 25 patients (control group) operated on the basis of the known technique reported in the literature. In 51 patients, these operations were accomplished in combination with different variants of procedures on the communicating and saphenous veins of the lower limbs. The time of some follow ups was as long as 7 years. The beneficial short-term results were obtained in 96.5% of cases whereas the long-term outcomes were positive in 92% of the basic group patients.
