ABSTRACT
OBJECTIVE: To establish nomograms for linear measurements of the frontal and occipital horns of the lateral ventricle and their relationship, in pregnant patients between 18 and 40 weeks of gestation and having attended 2 units of Maternal Fetal Medicine in Bogotá-Colombia. METHODOLOGY: A descriptive cross-sectional study with an analytical component was carried out on pregnant patients who utilized the ultrasound services at 2 Maternal-Fetal Medicine units in Bogotá, between 18 and 40 weeks of pregnancy who underwent measurement. From the anterior and posterior horns of the lateral ventricles, the fronto-occipital ratio was calculated at each gestational week, and nomograms were created for each of these variables. RESULTS: Nine hundred and seventy-eight patients were included in the study. The distance of the frontal horns ranged between 6.9 and 51.6 mm with a mean of 19.1 ± 5.8 mm; that of the occipital horns had a measurement between 8.7 and 53 mm with a mean of 28, 1 ± 8.9 mm; on the other hand, the fronto-occipital ratio (FOR) yielded a mean of 0.365 ± 0.067 (0.136-0.616) without bearing any relation to gestational age. The trend of normal values for the studied population is displayed, plotted in percentile curves and nomograms for each gestational age. CONCLUSION: The measurement of the frontal and occipital horns, and the calculation of the fronto-occipital relationship is technically possible between 18 and 40 weeks, finding that the anterior and posterior horns have a positive linear relationship with gestational age. Contrarily, the FOR does not correlate with the gestational age, it was possible to establish a table of percentiles that allows determining the normal values for these measurements during pregnancy.

Resumen OBJETIVO: Estimar la cantidad de pacientes con irregularidades menstruales que se embarazaron luego de una cirugía bariátrica (manga gástrica) y describir los desenlaces de los embarazos. MATERIALES Y MÉTODOS: Estudio retrospectivo de serie de casos de pacientes obesas y con irregularidades menstruales intervenidas mediante cirugía bariátrica (manga gástrica). Se operaron entre el 1 de junio de 2014 y el 31 de diciembre de 2019 en el Centro Médico Imbanaco Cali, Colombia. RESULTADOS: De 1418 cirugías bariátricas, tipo manga gástrica, 117 pacientes cumplieron con los criterios de inclusión, 80 de ellas se localizaron telefónicamente y aceptaron incluirse al estudio. Luego de la manga gástrica, el 86.25% (n = 69) de las pacientes logró la regularización de sus ciclos menstruales. Además, el 31% (n = 25) consiguió el embarazo, 80% (n = 20) de ellas tenían la intención de buscar el embarazo. Los desenlaces de esos embarazos fueron favorables, con partos a término, con adecuado peso y talla al nacer. CONCLUSIONES: Después de la cirugía bariátrica, tipo manga gástrica, en mujeres con irregularidades menstruales, 25 de las 80 pacientes se embarazaron y los desenlaces obstétricos fueron satisfactorios. Sin duda, hacen falta más estudios prospectivos para poder afirmar, con una mejor representación estadística, las repercusiones de la disminución del peso corporal en la tasa de fertilidad.
Abstract OBJECTIVE: To estimate the number of patients with menstrual irregularities who became pregnant after bariatric surgery (gastric sleeve) and to describe the pregnancy outcomes. MATERIALS AND METHODS: Retrospective study of a series of cases of obese patients with menstrual irregularities who underwent bariatric surgery (gastric sleeve). They were operated between June 1, 2014 and December 31, 2019 at the Imbanaco Cali Medical Center, Colombia. RESULTS: Of 1418 bariatric surgeries, gastric sleeve type, 117 patients met the inclusion criteria, 80 of them were located by telephone and agreed to be included in the study. After gastric sleeve, 86.25% (n = 69) of the patients achieved regularization of their menstrual cycles. In addition, 31% (n = 25) achieved pregnancy, 80% (n = 20) of them intended to seek pregnancy. The outcomes of these pregnancies were favorable, with full-term deliveries, with adequate weight and height at birth. CONCLUSIONS: After bariatric surgery, gastric sleeve type, in women with menstrual irregularities, 25 of the 80 patients became pregnant and the obstetric outcomes were satisfactory. Undoubtedly, more prospective studies are needed to be able to affirm, with a better statistical representation, the repercussions of the decrease in body weight on the fertility rate.
