Características ecográficas del saco vitelino durante el primer trimestre del embarazo como pbkp_redictor de aborto. Hospital José Carrasco Arteaga. Cuenca. 2016-2017

Abstract:

Introduction: Abortion is a public health problema, especially in developing countries, which occurs in 70 to 80% of fertilizations. The irregular, echogenic and altered size of the yolk sac can be associated with abortion; therefore, it is important to evaluate yolk sac ultrasound throughout the first trimester, since it can determine the pregnancy prognosis. Objective: To determine the ultrasound characteristics of the yolk sac during the first trimester of pregnancy as a pbkp_redictor of abortion. José Carrasco Arteaga Hospital. Basin. 2016 - 2017. Methods: This cross-sectional analytical study, was carried out on 397 clinical histories (finally working 407) of pregnant women in their 5th to 10th gestational weeks, which were referred to the imaging service of Hospital José Carrasco Arteaga during 2016 to 2017, with a follow-up every 4 weeks until reaching 20 weeks of pregnancy. Data was collected in a previous improved form through a pilot Project. The SPSS V 15 database was constructed.and analyzed by simple and multiple frequency tables for the bivariate analysis. Results: From the total of pregnant women, 24.82% had an abortion. Average age 28.75 years (± 5.9). Shape of the regular yolk sac developed 14.25% abortions, irregularly represented 10.57% (RP 37.06 IC95%: 15.08-91.01, p 0.000). Size less than 3mm and more than 5 mm developed 17.20% abortions (RP 4.08 IC95%: 2.51-6.61, p 0.000). Anechoic structure established 18.92% abortions in comparison to the echogenic and calcified structure 5.90% (RP 31.48 IC95%: 9.23-107.27, p 0.000). Conclusion: According to the results of this study, ultrasound characteristics of the yolk sac in terms of shape, size and structure were associated with further development of involuntary spontaneous abortion.
