Restoration of muscle-pump function in chronic venous insufficiency.

The direct venous pressure profile was recorded before and after treatment in 15 patients suffering from chronic venous insufficiency. Patients were treated conservatively, first by tight elastic support and walking exercises, then by eliminating the points of blood shunting by sclerotherapy of the incompetent perforators. The average venous pressure drop during tiptoeing was increased from 31.6% to 50.9% (P less tan 0.01), and the time required for return to the resting venous pressure level increased from an average 6 seconds to 12.9 seconds (P = 0.01). These values indicate a significant improvement in the functioning of the muscle pump of the calf, and are paralleled by clinical and subjective improvement. Wr recommend this method of treatment in cases of chronic venous insufficiency. We also wish to point out the importance of repeated direct venous pressure profile recording as a means of assessing the effectiveness of treatment in cases of venous disorders.

The use of photoplethysmography in the assessment of venous insufficiency: a comparison to venous pressure measurements.

In an attempt to develop a noninvasive test to assess objectively the magnitude of venous valvular dysfunction in pathologic states, photoplethysmography (PPG) was compared to venous pressure in the saphenous vein at the ankle. Simultaneous venous pressure and PPG recordings were taken before, during, and after exercise with subjects in the sitting position. In a total of 338 paired measurements in 24 normal, 25 postphlebitic, and 14 varicose limbs, PPG and venous pressure tracings appeared to be identical; data points had a correlation coefficient of great significance (r = 0.898). Postexercise recovery times clearly separated the normal from the postphlebitic limbs. Varicose limbs were assessed accurately regarding results of proposed surgery using an above-knee tourniquet. It appears that the PPG evaluation provides information comparable to venous pressure studies and does so more quickly and noninvasively. The test holds promise in measuring results of direct venous reconstructive surgery as well as in venectomy procedures.

Ambulatory calf volume plethysmography in the assessment of venous insufficiency.

Ambulatory calf volume plethysmography has been used to study venous insufficiency in 50 lower limbs. The results demonstrate that it is possible to determine the presence of venous insufficiency and differentiate between normal limbs, limbs with superficial venous insufficiency only, limbs with deep venous insufficiency and limbs with deep venous insufficiency and occlusion by determining the ambulatory volume change and maximum venous outflow or venous volume.

[Triggering of immunologic reactions by Strehler's pressure wave therapy in patients with chronic venous insufficiency].

Thirteen patients with chronic venous insufficiency of the legs, mostly with ulcerations, were treated during four weeks by pressure wave therapy following the method of Strehler. Some parameters of circulation, blood, and immunology were controlled at the beginning, at the third, tenth, twentieth and fourtieth day. There was a tendency to normalization of hypo- and hypertension, of the blood calcium and kalium, and especially, there was a significant increase of IgG and C'4 during the treatment with decrease of the IgM. Other parameters did not show specific alterations. The mobilisation of edema by pressure wave therapy seems to arise an immunologic reaction, probably by activating antigens or antigen-antibody complexes.

[Surgical correction of venous insufficiency following arteriovenous fistula for hemodialysis].

The percentage of venous insufficiency in the original Cimino-Brescia shunt is very low. In cases of venous insufficiency, early diagnosis is important; operative correction is then easily performed. Ligature of the distal venous limb next to the anastomosis is the treatment of choice, providing the proximal limb is still open. If the proximal limb is obstructed, the distal venous part is dissected and anastomosed to a more proximal vein. The result is an immediately functioning shunt for dialysis.

[Chronic venous insufficiency of the lower extremities and a halt to absenteeism].

In this work authors experiences about the influence of operation on absentism decrease in 2450 surgically treated patients with chronic venous insufficiency signs and clinical manifestations of various intensity have been presented. In the introduction higher frequency of this disturbance and great financial loss which appear as consequence of this disease, as well as complications which affect the patients with syndrome of chronic venous insufficiency have been described. The authors particularly emphasize still intensive conservative attitude in the therapy of this illness, what leads to its deterioration. Further the authors describe the method of their investigation and the results obtained have been presented in tables. That the operative treatment protects the respective patient with such disturbances from more serious clinical manifestations as well as adequate complications of these disturbances has been emphasized in the conclusion. Further it has been pointed out that immediately applied operative treatment obviously decreases absentism.

[Anatomical and physiological assessment of the collateral circulation in experimental femoral artery ligation in venous insufficiency].

Peculiarities of collateral circulation following isolated and combined ligations of the femoral vessels were studied in experiments on 62 dogs through physiologic and anatomic investigation methods. It has been shown that the ligation of the vein prevents the exsanguination of the limb, arising from an injury to the main artery, favours an accelerated anatomic reconstruction of the arterial collaterals, but increases microcirculatory disturbances, aggravates tissue ischemia and disorder of the acid-base balance, which as a whole evidences a detrimental effect of concomitant venous insufficiency upon the process of the restoration of the circulation in the limb.

[Functional disorders of the venous muscular pump seen in chronic venous insufficiency].

The study of the functioning of the venous muscle pump by means of plethysmographic tests allowed us to discover a clearly marked condition in the varicose veins combined with chronic venous deficiency and in the thromboses of the deep veins. In the case of varicose veins, we found an interdependence between the gravity of the functional lesions and the existence of insufficient perforating veins. The study, which dealt with cases of thrombosis, showed that the trophic skin lesions appear only after several years of poor nervous pump functioning.

[Critical study of the therapeutic effects of phlebotropic drugs on chronic venous insufficiency].

The authors describe two types of test. Their aim was to verify the therapeutic potency of drugs used in the treatment of chronic venous disorders. The tests were carried out using both a single prescription and using successive prescriptions. The results showed that with strict clinical surveillance, phlebotropic drugs had definite therapeutic effects both on the subjective disturbances and on certain objective parameters.
