МИКРОХИРУРГИЧЕСКИЕ ПОРТОКАВАЛЬНЫЕ АНАСТОМОЗЫ ПРИ ПОРТАЛЬНОЙ ГИПЕРТЕНЗИИ (ЭКСПЕРИМЕНТАЛЬНОЕ ИССЛЕДОВАНИЕ)

The section on anatomy justification of microsurgical spleno- and mesorenal anastomosisperformedona sectionmaterial (54humancadavers). The studyof topography and anatomy features of splenic, renal and superior mesenteric veins were conducted, their morphological characteristics, the histology characteristics of vascular anastomoses, the parameters of their tightness and mechanical strength. Experimental studies carried out on 48 mongrel dogs. There have been five sets of experiments. The analyses of morphological and functional status of improved vascular anastomoses in the short and long periods after surgery were accomplished.На 54 органокомплексах трупов людей изучены топографо-анатомические особенности селезеночной, почечной и верхней брыжеечной вен, их морфологические характеристики, гистотопографические характеристики сосудистых сплено- и мезентерикоренальных анастомозов, параметров их герметичности и механической прочности. Экспериментальная часть исследований выполнена на 48 беспородных собаках в 5 сериях экспериментов. Проведен анализ морфологического и функционального состояния усовершенствованных вариантов сосудистых анастомозов в ближайшем и отдаленном периодах после операции.
