Possibilities of ultrasound in reno-cardio-cerebral continuum with arterial hypertension in children

K.E. Trubnikova, T.N. Nazarov, S.A. Madzhidov

We examined 206 children from 13 to 17 years with essential hypertension (EAH): a stable hypertension (SAG) - at 86, labile arterial hypertension (PAH) - at 60, without arterial hypertension - 60. Daily monitoring of blood pressure, transcranial Doppler study, triplex investigation of brachiocephalic artery and renal hemodynamics were performed. Hypokinetic type of blood flow in the vertebrobasilar pools registered in SAG. In children with PAH and SAG showed a significant increase in the diameter of the common carotid arteries. In the study of renal hemodynamics conducting ortoclinostatic test reveal reduced velocity at the level of the main trunk of the renal artery and segmental arteries and IR (<0,52), and the increasing of blood flow through the veins in the position of orthostasis, confirming the inclusion of arteriovenous shunting. Integrated assessment of hemodynamics in the evaluation of patients with hypertension to determine the presence of reno-cardio-cerebral continuum among adolescents with a stable form of hypertension.

Keywords: cerebral hemodynamics, renal hemodynamics, clinoortostasis, nephroangiopathy.
