Ультразвуковая диагностика ранних признаков нарушений почечной гемодинамики у больных с хроническим лёгочным сердцем

Ультразвуковая диагностика ранних признаков нарушений почечной гемодинамики у больных с хроническим лёгочным сердцем

Abstract

Обследовано 107 пациентов с хронической обструктивной болезнью лёгких (ХОБЛ) на разных стадиях формирования хронического лёгочного сердца (ХЛС), которым проводилось исследование лёгочной, внутрисердечной и почечной гемодинамики методом ультразвукового дуплексного сканирования. Установлены ранние допплерографические критерии нарушения ренального кровотока у пациентов с ХОБЛ: снижение диастолической скорости кровотока, увеличение пульсационного индекса в дуговых и междолевых почечных артериях. Полученные результаты свидетельствуют о том, что прогрессирование бронхиальной обструкции, артериальной гипоксемии, гиперкапнии и ацидоза приводят к нарушению лёгочной, внутрисердечной гемодинамики, а также активизации альдостерона плазмы и активного ренина плазмы. Данные взаимосвязанные процессы явились причинами снижения почечного кровотока у больных с декомпенсированным ХЛС на всех уровнях почечных артерий.

We examined 107 patients with chronic obstructive pulmonary disease (COPD) at different stages of the formation of chronic pulmonary heart (CPH), studying lung, heart and renal hemodynamics by ultrasound duplex scanning. The authors revealed early Doppler criteria disorders of renal blood flow in patients with COPD: a decrease in diastolic blood flow, an increase of pulse index in arch and interlobular renal arteries. The results obtained suggest that the progression of bronchial obstruction, arterial hypoxemia, hypercapnia and acidosis violate lung, intracardiac hemodynamics, as well as activation of plasma aldosterone and active plasma renin. These related processes have caused a reduction in renal blood flow in patients with decompensated chronic cor pulmonale at all levels of the renal arteries.
