Isotopic lymphography offers a very useful method to assess pre-fascial and subfascial lymph transport in the leg. Labelled microcolloids are injected either subcutaneously (pre-fascial lymph-drainage) or into the calf muscle (subfascial lymph-transport) and a standardized walking exercise is performed. Today we prefer a quantitative measurement which consists mainly in a combination of a transmission and an emission-scintigraphy. In the acute stage of a deep vein thrombosis and also in the post-thrombotic limb the deep lymphatic transport is constantly diminished or absent. At the same time the pre-fascial lymph-drainage is enhanced except in cases with recurrent erysipelas or after injection of the tracer into the border of an ulcer.

[Indirect lymphangiography and transcutaneous measurement of oxygen pressure in white atrophy].

The measurement of the TCPO2 and indirect lymphography help us to understand the pathogeny of white atrophy, especially when their results are compared with discoveries produced by other intra-vital methods such as the laser-Doppler and biomicroscopy.

[Proof of the effectiveness of compression by nuclear medicine, plethysmography and venous pressure measurement].

1) In a lying down position a) immediately and under rapid compression, one observes a reduction in muscle flow as well as a reduction of the perfusion of the foot and of the systolic pressure of the big toe. After disinfiltration of the leg by compression, the muscular flow more than doubles (clearance with Xenon 133). b) a reduction in the venous blood volume of the limb by about 1/3. c) an increase in the venous circulation speed by about 1.5 times (tracer in a vein of the back of the foot). The degree of change is depending from the pressure of the compressive bandage (in a lying down position, between 20 mmHg and a maximum of 40 mmHg). 2) while walking a) shortening of the pathological refluxes in the veins of the lower limbs (directional Doppler). b) improvement of the pump output (increase inthe volume of blood pumped upwards), and a variable influence of the peripheral venous pressure (simultaneous methods of plethysmography of the foot and the venous pressure). c) reduction of edema, improvement of the disturbed lymphatic flow (plethysmography, lymphotropic tracers with radioactive marking).

[Limitations of venous function diagnosis using laboratory apparatus - possibility of errors].

The authors discuss some questions concerning the limitations and the errors of methods involving the Sonar Doppler, Plethysmography and Phlebodynamics in phlebology diagnosis. The Doppler technique is the most useful one in detecting a valvular insufficiency or a venous obstruction of the thigh. Plethysmography is a simple method of detecting a pelvic or femoral thrombosis. It does not make it possible, on the level of the calf, to make a distinction between a recent thrombosis or a post-thrombotic state. It cannot be used when there is a large edema. It is inadequate for studying the function of the muscular pump of the calf, which can also be done by phlebodynamics. This method is now the most precise technique for quantitatively studying the total function of the muscular pump of the calf. It can be easily reproduced, and the effect of therapeutic measures can thus be anticipated.
