Preservación de placenta humana. Técnica anatómica

Abstract

The fixation, conservation and preservation techniques, with academic and didactic aims, look for the way to find substances that maintain, as far as it is possible, the natural state of the body or organs, permeating the tissues, allowing an easy assembly, providing a detailed information and offering a three-dimensional view of the structures.The objective of the research was the view of angioarchitecture of the human placenta. The samples used were taken from the Servicio de Ginecología y Obstetricia, Unidad de Partos, del Hospital Hernán Enríquez Aravena, de Temuco, IX Región, Chile. All placentas were of a completed gestation condition, of single and normal childbirths.The placentas were injected with hardening solutions, and subject to corrosion with hydrochloric acid 32,4 %. This allowed the creation of a pattern of arteries and veins. Our results confirm that this technique can be useful in teaching and investigation, in view of the low costs and excellent results in the macroscopic visualization of the vascular plot of the human placenta.
