МОРФОМЕТРИЧЕСКИЙ АНАЛИЗ ПРИМЕНИМОСТИ УРАВНЕНИЙ MURRAY C.D. ДЛЯ ЧИСЛЕННОГО МОДЕЛИРОВАНИЯ СОСУДИСТЫХ ДИХОТОМИЙ ПОЧКИ ЧЕЛОВЕКА

Abstract

Цель. Провести анализ применимости уравнений Murray C.D. для расчёта значений углов дихотомий внутриорганного артериального и венозного русел почки человека. Материал и методы. Были исследованы внутриорганные артерии и вены почек. Почки полученны на аутопсии у людей (возраст от 36 до 74 лет; 9 человек мужского пола, 8 – женского), изготовлены 17 коррозионных препаратов: 9 препаратов артериальное русло, 8 – венозное. Визуализацию проводили с помощь микротомографа BRUNKER SkyScan 1178. Для морфометрии использовали программный пакет blender с надстройкой NeuroMorph Measuring tools. Измеряли диаметры сегментов (D, dmax, dmin) и углы между ними (αmax, αmin). Для расчетов углов дихотомии пользовались уравнениями Murray C.D. Результаты. Установлено наличие четырех структурно-различных типов дихотомий, составляющих внутриорганное сосудистое русло почки. Показано, что применять уравнение Murray C.D. для расчетов величины угла αmax можно для любых структурно-различных типов сосудистых дихотомий почки человека. Однако использовать уравнение Murray C.D. для расчетов значений угла αmin нельзя для артериальных и венозных дихотомий 1-го структурно-различного типа и для 2-го типа венозных дихотомий. Заключение. Применение уравнений Murray C.D. для численного моделирования сосудистых дихотомий почки человека носит ограниченный характер. Это необходимо учитывать при создании структурных математических моделей сосудистого русла почки человека.
