Varicosities - Fscaresystems Viridex Rf Bedienungsanleitung

MANUEL
RF
When walking - contraction phase: It varies between 85 and 95 mm Hg in the medial malleolar
saphenous vein just before the heel leaves the ground and falls to 70 mm Hg when the foot is
lifted.
Release phase: the leg musculature relaxes and then the crural musculature contracts. When
the heel touches the ground and rests, the pressure falls to 46 mm Hg.
The drop in venous pressure at the ankle to below the hydrostatic pressure occurs after 3 to
12 paces, independently of the walking speed.
Speed of Veinous Blood Circulation
The speed of the venous blood flow in the vena cava is 10 cm/s. It varies depending on the
position of the subject. In dorsal decubitus the speed of circulation in the legs is 2 cm/s. It falls
by 40% in orthostatism.
It increases by 20% when walking, 60% during gymnastic exercise of the toes, 80% when
wearing an elastic restraint, 90% during gymnastic exercise of the feet, 150% when the end of
the bed is raised by 20 %, 270% when the subject is lying down with the legs raised vertically,
and 340% peddling in the same position

Varicosities

Varicosities fall within the two worlds of phlebology and aesthetics.
Modern phlebology should be based on their co-existence. These are not capillaries, but
permanent dilations of the intradermal microvenules with a diameter that varies between 0.1
and 1 mm.
They differ in appearance:

Isolated in small branches

Diffuse spider's webs

In the form of hairlines.
They mostly affect certain areas: internal and external knee - thigh - internal ankle - external
leg. They may be spontaneous or secondary and occur after stripping or sclerosis, in which
case they are referred to as matting.
Their colour varies from bright red to dark blue and the diameter depends not only on the
depth, but also on the oxyhemoglobin content.
They are covered by various medical disciplines: phlebology - angiology - dermatology -
aesthetic medicine - plastic surgery - vascular surgery - internal medicine.
