| Popis: | Objective: To investigate the geometric shape of the ductus venosus between 10–13 weeks of gestation. Patients and methods: Ductus venosus measurements were performed in 64 normal human fetus using ultrasound color Doppler imaging. The geometrical measurements obtained were: length (n = 64), isthmic width (n = 34) and outlet width (n = 20). For statistical analysis, the analysis of variance, linear regression, Kruskal-Wallis terst and the Spearman correlation were used. Results: At 10–13 weeks of gestation, the ductus venosus length indicates a continuous growth and the width did not change. The measurements (median) were: length = 2 mm, isthimic inlet = 1.4 mm, and outlet width +1.4 mm. Conclusion: The new geometric shape of the ductus venosus between 10–13 weeks of gestation has a cylindrical and not a slender trumpet-like shape as defined previously in the literature. |
