Return of blood at lower limb
has a cardiopet, from surface to deep depends of pressure difference.
Our study using duplex color tries to present some aspects about reflux
on some segments in correlation with the contraction force of the
muscle, isotonic contraction or isometric contraction, that we meet at
some athletes. The records have been made in dorsal decubit,
orthostatism and orthodynamism. Material and method: The study has
included 28 athletes that participate to sport activity and that have
an overuse of muscle venous pumps. We used Doppler echography for
assessment the points of venous reflux.
It wasn’t taken in consideration the
constitutional biotype and we observed that a venous reflux exists at
perforates shank (VpG10 /28) and at femoral- saphen junction
(JSF5/28). Insufficiency of VpG and of JSF are frequently (15/28) and
are most present in sports that involve an important and unexpected
increase of intrabdominal pressure. Disorders of valvular system after
hydraulic shock can be supported by venous wall that can be hyperplasic
because a great speed of blood flux exists. Venous flux is not changed
in relation with respiratory activity comparative with the martor lot.
Conclusions: These reflux sources can become
the origin of chronic venous diseases of lower limb.
