[en] Objective: To evaluate the prevalence of obstetric complications in pregnancies obtained after technique of intracytoplasmic sperm (ICSI). Methodology: This is a descriptive cross-sectional observational study. Data were collected from pregnancies achieved by technique of in vitro fertilization/intracytoplasmic sperm injection of sperm (IVF-ICSI) in the Hospital Torrecárdenas of Almeria, from March 2009 to January 2013, by consecutive sampling type. The variables were age, nationality, parity, cause of infertility, the type of medical history (single or multiple), pregnancy, treatment during pregnancy, obstetric complications (hypertensive disorders, gestational diabetes, premature labor, premature rupture of membranes, chorioamnionitis, placental disorders, intrauterine growth restricted, small fetus for the gestational age, malformations, delivery, perinatal morbidity. Although the techniques of assisted reproduction are several depending on the type of reproductive dysfunction (artificial insemination, IVF conventional or intracytoplasmic sperm injection of sperm), in our study only took into account the pregnancies obtained after submitting to the couple to intracytoplasmic sperm injection or ICSI sperm. Results: 270 pregnancies were obtained by ICSI, but included a final sample of 75 pregnancies. The average age was 33,53 years. The main cause of reproductive dysfunction was male factor (49,3 %).The total births, 22,6 % were twins. Of all the pregnant women, 29,5 % presented some background of interest, being the most prevalent thyroid disease (10.7 %), especially hypothyroidism. No pregnant woman suffering from alcoholism, vascular disease, polycystic ovary syndrome, pregestational diabetes, kidney disease, liver failure, and psychiatric. 6 Women (8 %) smoked. In regard to obstetric complications, 32 pregnant women (42,6 %) had some, being the most prevalent the hypertensive disorders of pregnancy (20 %), followed by fetus with intrauterine growth restricted (CIR) (10,7 %) and risk of preterm delivery (APP) (10,7 %). Premature Birth in 21,33 % of the total and spontaneous labor only 19 cases (25.3 %). The total rate of cesarean sections was 44% (28% and 16% scheduled urgent), compared to 56% of vaginal births (42,7 % and 13,3 % eutocic instrumental). Of the total of unique gestations, 73% had a vaginal birth, compared to 37% which ended by cesarean section, and the total of twins, 70% had cesarean delivery compared to the 30% that ended through vaginal delivery. Conclusions: The results seem to indicate an increase of obstetric complications, mainly hypertensive disorders of pregnancy, along with an increase in the rate of c-sections, both in single pregnancies and twins. You should delve into the possible associated complications, prevention, and treatment, obtaining conclusions with the highest level of scientific evidence to help us identify the risk.

[es] Objetivo: Evaluar la prevalencia de complicaciones obstétricas en gestaciones obtenidas por técnica de Microinyección Intracitoplasmática de espermatozoides. Métodos: Se trata de un estudio observacional, descriptivo y transversal. Los datos se obtuvieron de los embarazos conseguidos por técnicas de Reproducción Asistida: Fecundación in vitro convencional y microinyección intracitoplasmática de espermatozoides (FIV-ICSI), en nuestro hospital entre marzo de 2009 enero de 2013, utilizando muestreo consecutivo. Las variables de estudio fueron: edad, nacionalidad, paridad, causa de esterilidad, tipo de gestación (simple o múltiple), antecedentes personales, tratamiento durante la gestación, trastornos hipertensivos, diabetes gestacional, amenaza de parto pretérmino, rotura prematura de membranas pretérmino, corioamnionitis, trastornos placentarios, crecimiento intrauterino restringido, feto pequeño para la edad gestacional, malformaciones fetales, tipo de parto, morbilidad y mortalidad perinatal. Resultados: De 270 embarazos obtenidos por fecundación in vitro, se obtuvo una muestra final de 75. La edad media fue 33,53 años. La causa de esterilidad principal fue masculina (49,3%). 22,6% fueron gemelares. El antecedente más frecuente fue el trastorno tiroideo (10,7%). La heparina fue el fármaco más indicado en la gestación (12%), seguido de antihipertensivos (9,3%). 32 gestantes (42,67%) presentaron alguna complicación obstétrica, la más prevalente la hipertensión (20%), seguida de feto con crecimiento intrauterino restringido (10,7%) y amenaza de parto pretérmino (10,7%). Tuvo lugar parto pretérmino en 21,33%. Partos espontáneos y eutócicos ocurrieron en 19 casos (25,3%). Finalizaron en cesárea 44%, frente al 56% vía vaginal. Presentaron bajo peso el 42% de recién nacidos, y se registró una muerte perinatal. Conclusiones: Los resultados parecen indicar un aumento de las complicaciones obstétricas, principalmente trastornos hipertensivos del embarazo, junto con un aumento en la tasa de cesáreas, tanto en embarazos simples y gemelos. Se debería profundizar en las posibles complicaciones asociadas, prevención y tratamiento, obteniendo conclusiones con mayor nivel de evidencia científica que nos ayudaran a individualizar el riesgo.
