Objectification of compression therapy haemodynamic effect by means of light reflex rheography.

Light reflex rheography (LRR) is one of the non-invasive diagnostic methods which makes it possible to examine venous haemodynamics. Through the use of this method we wanted to prove the positive influence of compression therapy on varices of the lower extremities in the 2nd degree chronic insufficiency. In all, 32 patients were examined (39 extremities), and evaluations were done on them of the initial venous refilling time-Ti, i.e. a segment of the LRR curve during the first three seconds after the cessation of muscle work (12 dorsal flexions sitting). Measurements were made without stockings and with the use of the 2nd compression class stockings made by Loana and with the use of Cambren the 1st compression class stockings. With the 1st compression class stockings, measurements were made with one and two stockings simultaneously. The arithmetic mean of the values measured in the individual groups was evaluated by Student's t-test. Our results confirmed the anticipated prolongation of the initial time (Ti) segment in the monitored patients, even when the 1st class Cambren C stockings were used. Especially when two of these stockings were used simultaneously, the Ti period was fully comparable to the Ti values when the 2nd class compression stockings were used. It has been demonstrated that when two lower compression class stockings are used simultaneously, there is a significantly increased compression effect and an improvement of the function parameters, even in patients with varices and the 2nd degree chronic venous insufficiency.

[What is the relation between pressure parameters and claudication distance?].

The authors examined the relationship between the ankle pressure, or pressure gradient on the one hand, and the walking distance and different actions, i.e. equalting and standing on tip toes, on the other hand. In 56 male patients with obliterating atherosclerosis, the first stage showed both pressure parameters as closely correlated to the final claudication distance, but not to the actions indicated above. At the second stage, 62 persons showed both the initial and final claudication distances as dependent on the poststenotic pressure as well as on the pressure gradient. Stepwise regression analysis showed a significant dependence of both distances on the lowest pressure measured on four crural arteries. The closest correlation [R = 0.98] was found between the initial and final claudication distances which persisted even after elimination of all pressure parameters.

Some interrelations between blood pressure parameters and claudication distances.

Sixty males and 2 females with the mean age of 58.1 years ranging from 39 to 80 years with atherosclerotic lesions of the arteries of lower extremities were studied. The claudication distance was subdivided into two segments: the first included the distance up to the onset of pain and the second one when the patients had to stop walking because of the severity of pain. The systemic systolic pressure and the poststenotic ankle pressure over both arteries on both calves by a Doppler ultrasound apparatus were measured and the individual pressure gradients were calculated. It was demonstrated that both claudication intervals were related to the poststenotic pressure as well as to the pressure gradient. The stepwise regression analysis showed a significant relationship between both distances and the lowest value of all ankle pressure measurements over four tibial arteries. The closest correlation (R = 0.98) was recorded between the initial and final claudication distance and it persisted even after the elimination of all pressure parameters.
