Conclusion
By multi modalities ultrasound were obtained by quantitative and qualitative characteristics bone sarcomas in children and adolescents.
Pathological mechanisms of hemodynamic support of the affected limb may include systemic increase in CO,
regional changes in vascular tone and against this background - the redistribution of certain volumes of blood between from healthy to the affected limbs.
Comparative analysis of quantitative characteristics proximal blood flow in both healthy and the affected limb helps effectively distinguish between sarcomas and benign tumors of bones.
It is established that the relative magnitude of the - %PI, characterizing changes in hemodynamic of affected limb,
and,
consequently,
to a certain extent its supply blood,
is associate with predicting EFS five- year in patients with bone sarcomas.
Thus,
relative changes of the Doppler pulsatility index in femoral arteria of affected limb is opening a new features for prediction of event-free survival in patients with bone sarcomas.
