ABSTRACT

Introduction: external biometric measurement in later stages of the embryonic period in humans can have regularities and associations with internal organs' biometry, which is also of great impact on their anatomy, physiology and pathology (heart, lungs and liver); this matter has not been well explored yet.
Objective: to establish possible associations between external biometric measurement of the embryo and the biometry of its heart, lungs and liver in later stages of the embryonic period.
Methods: a correlational study was conducted in a total of 11 human embryos of 20, 22 and 23 stages of the embryonic period belonging to the Embrioteca of the University of Medical Sciences in Villa Clara; these were distributed in 3 study groups: heart (6), lungs (9) and liver (7). Six external morphometric variables for embryo were correlated and five internal ones for organ studied, which represents a total of 11 internal variables for embryo; a linear correlational study was carried out among all these variables.
Results: lateral distances of heart and liver were correlated by means of skull-spine length of the embryo and transversal distance of the thoracic and abdominal cavities respectively. All pulmonary variables were correlated with embryonic weight, most of them using skull-spine length, and some others using thoracic diameters.
Conclusions: multiple correlations found between external and internal variables for the three groups support quantitatively the correspondence of the development in these stages and suggest the possibility of predicting the size of organs based on external biometric measurement.
