Systemic and regional hemodynamics in children and adolescents with bone sarcomas of upper and lower limbs

The aim: To study the hemodynamic of upper and lower extremities taking into account of cardiac output and volume of tumors in patients with bones sarcomas. Patients and methods: Analysis of data obtained during of the initial ultrasound examination of the 56 patients aged 8 – 18 years with morphologically proven bone sarcomas of extremities was performed. Were estimated: cardiac output (CO), volume of blood flow in main femoral and subclavian artery (Q ml/min), indices – resistance and pulsation (RI, PI), as well as size of their percentage deviations for the affected limb compared with the contralateral (%Q, %…
