Malformación de Arnold Chiari tipo 1 en embarazada, reporte de caso clínico / Case Report: Arnold Chiari type 1 malformation in pregnant women

Resumen ANTECEDENTES: La enfermedad de Arnold-Chiari es una malformación congénita rara del sistema nervioso central, caracterizada por el descenso del cerebelo por debajo de 5 mm del nivel del foramen magno, con o sin siringomielia asociada (tipos I o II). La edad media a la que se detecta la enfermedad tipo I son los 40 años. Es más frecuente en mujeres con una relación 3:1. Sus manifestaciones son: cefalea occipital (70-90%), dolor neuropático de segmentos cervicales (40-70%); hiperreflexia de extremidades inferiores (51%); atrofia de manos (35%) y paresias de extremidades superiores (35%) e inferiores (17%). El diagnóstico se establece con base en la resonancia magnética. OBJETIVO: Analizar el comportamiento anestésico-obstétrico en una paciente embarazada y el riesgo de complicaciones derivadas de los cambios fisiológicos y de la gestación. CASO CLÍNICO: Paciente de 30 años, con 38 semanas de embarazo y diagnóstico de enfermedad de Arnold-Chiari tipo I, con adecuado control neurológico y obstétrico y evolución satisfactoria. El embarazo finalizó por parto. CONCLUSIONES: La atención médica a la paciente del caso fue adecuada porque no se registraron complicaciones y fue posible darle el alta del hospital en muy poco tiempo.

Abstract BACKGROUND: Arnold-Chiari disease is a rare congenital malformation of the central nervous system, characterized by descent of the cerebellum below 5 mm from the level of the foramen magnum, with or without associated syringomyelia (types I or II). The average age at which type I disease is detected is 40 years. It is more frequent in women with a 3:1 ratio. Its manifestations are occipital headache (70-90%), neuropathic pain of cervical segments (40-70%); hyperreflexia of lower extremities (51%); atrophy of hands (35%) and paresis of upper (35%) and lower extremities (17%). Diagnosis is established based on magnetic resonance imaging. OBJECTIVE: To analyze the anesthetic-obstetric behavior in a pregnant patient and the risk of complications derived from physiological and gestational changes. CLINICAL CASE: 30-year-old patient, 38 weeks pregnant and diagnosed with Arnold-Chiari disease type I, with adequate neurological and obstetric control and satisfactory evolution. The pregnancy was terminated by delivery. CONCLUSIONS: The medical care of the patient in the case was adequate because no complications were recorded, and it was possible to discharge her from the hospital in a very short time.

Morbilidad y mortalidad del recién nacido en un hospital privado de México / Newborn morbidity and mortality in a private hospital in Mexico

Resumen OBJETIVO: Estimar la morbilidad y mortalidad de los recién nacidos vivos en un hospital privado de México, a través de los ingresos a las unidades de cuidados intensivos neonatales y de terapia intermedia neonatal. MATERIALES Y MÉTODOS: Estudio de serie de casos de recién nacidos en el Hospital Ángeles Lomas, Estado de México, que ingresaron a la unidad de cuidados intensivos neonatales o a la unidad de terapia intermedia neonatal entre 2016 y 2019. Se incluyeron todos los recién nacidos vivos, mayores de 24 semanas de gestación. Se efectuó un análisis descriptivo y se calcularon medias, porcentajes y desviaciones estándar. RESULTADOS: Se registraron 4234 recién nacidos, de ellos 13.7% fueron prematuros. Ingresaron 478 (11.3%) neonatos a cuneros dedicados a la atención de sus morbilidades, 203 a la unidad de cuidados intensivos neonatales (4.8%) y 275 a la unidad de terapia intermedia neonatal (6.5%). Las principales causas de ingreso a cuidados intensivos neonatales fueron: retención de líquido pulmonar (32.5%), enfermedad de membrana hialina (27.6%) y sepsis neonatal (10.3%). Las principales causas de ingreso a la unidad de terapia intermedia neonatal fueron: retención de líquido pulmonar (41%), hiperbilirrubinemia multifactorial (15.2%) e hiperbilirrubinemia por incompatibilidad de grupo (11.6%). La tasa de mortalidad neonatal fue de 2.7 por cada 1000 nacidos vivos, las principales causas de defunción fueron: enfermedad de membranas hialinas complicadas con sepsis neonatal y asfixia perinatal. CONCLUSIÓN: No se encontraron diferencias importantes en el hospital privado estudiado en comparación con otros estudios que valoran la morbilidad y mortalidad neonatal. La tasa de mortalidad en este hospital fue menor a la del país, pero la media de días en la unidad de cuidados intensivos neonatales fue mayor y la tasa de prematuridad ligeramente mayor a la reportada en países desarrollados.

Abstract OBJECTIVE: To estimate the morbidity and mortality of live newborns born in a private hospital in Mexico, through admissions to the neonatal intensive care unit (NICU) and the neonatal intermediate therapy unit (NITU). MATERIALS AND METHODS: A series of cases were carried out of the births of the Hospital Ángeles Lomas (State of Mexico) that have entered the NICU / NITU from 2016 to 2019. All live newborns older than 24 weeks were included. A descriptive analysis was performed calculating means, percentages and standard deviations. RESULTS: 4,234 newborns were registered, of which 13.7% were premature. 478 (11.3%) newborns were admitted to pathological nurseries, 203 to the NICU (4.8%) and 275 to the NITU (6.5%). The main causes of admission to the NICU were retention of pulmonary fluid (32.5%), hyaline membrane disease (27.6%), and neonatal sepsis (10.3%). The main causes of admission to the NITU were retention of pulmonary fluid (41%), multifactorial hyperbilirubinemia (15.2%) and hyperbilirubinemia due to group incompatibility (11.6%). The neonatal mortality rate was 2.7 out of 1000 live births, the main causes of death were hyaline membrane disease complicated by neonatal sepsis and perinatal asphyxia. CONCLUSION: No significant differences were found in the private hospital studied compared to other studies evaluating neonatal morbidity and mortality. The mortality rate in this hospital was lower than that registered countrywide, however the average number of days in the NICU was higher and the prematurity rate slightly higher than that reported in developed countries.

[Vaginal birth after cesarean. A safe option?]. / Parto después de cesárea una opción segura?

OBJECTIVE: To compare the beginning and evolution of labor variables such as demographic characteristics, obstetric and perinatal outcomes of patients with vaginal birth after cesarean (VBAC). MATERIAL AND METHODS: Observational, retrospective and retro elective trial purposes of comparative analysis, were divided into groups by the onset of labor; spontaneously versus induction and by the labor evolution; spontaneously versus conduction. Being analyzing by Student's T and Fisher test. RESULTS: According the ACOG criteria. 136 patients with prior cesarean section were eligible to labor. The indications of previous cesarean have a trend of a non-recurring etiology, being the elective cesarean section the most common. Regarding the onset, 78% was spontaneous and 22% had an induction. Comparing the demographic characteristics it stands a greater number of deliveries, history of vaginal delivery, a higher Bishop score, fetal weight estimated lower and higher intergenesic period. As a perinatal prognosis, the study has shown be safe with a positive outcome. Conclusions:Vaginal birth after cesarean is safe, that should be offered to all women with a low transverse incision, with an intergenesic period greater than 18 months, whit a singleton pregnancy, in a cephalic presentation, with an appropriate fetal weight, and without obstetric contraindications of vaginal delivery.

[Chronic pelvic pain and cervical endometriosis after a subtotal hysterectomy]. / Dolor pélvico crónico y endometriosis cervical después de histerectomía subtotal.

The ectopic location of endometrial glands and stroma may cause the formation of a tumor known as endometrioma. It almost always occurs in the ovary, and due to its characteristic appearance has been called "chocolate cyst". Cervical localization of this disease is extremely rare, and when it occurs, tends to be an exocervical and/or endocervical injury, as a result of cervical procedures. We communicate the case of a patient with cystic endometriosis in the cervix after a subtotal abdominal hysterectomy, performed by obstetric hemorrhage. Even though there have been reports about cases of cervical endometriosis, most of them have been reported as superficial cervical endometriosis and as a discovery after a total hysterectomy or cervical biopsy, in some cases even with original diagnosis ofAGUS (atypical glandular cells of undetermined significance). We concluded that in this case, instrumented uterine curettage and subtotal hysterectomy by obstetric indication are a possible origin of cervical endometriosis, due to "seeding" endometrial tissue during the curettage in a friable cervix.

[Asynchronous birth in twin pregnancy. Literature review and case report]. / Nacimiento asincrónico en embarazo gemelar. Revisión de la bibliografia y reporte de un caso.

BACKGROUND: The incidence of multiple pregnancy has grown, some of these cases are attributed to assisted reproduction techniques, with the consequent increase of maternal-fetal morbidity. There have been few reported cases of delayed interval delivery with different perinatal outcomes. This is a case report of a double twin pregnancy with delayed delivery of the second fetus after birth of the first one within 15.5 weeks of pregnancy, and the second one birth at 38.4 weeks, 158 days after the first one. Reported diagnosis, treatment and perinatal outcomes. CONCLUSIONS: The mean reported time to extend the pregnancy after the evacuation of the first one is 7 to 153 days. In this case the pregnancy was held 158 days, more than in the rest of the reported cases, maybe due to gestational delivery age of the first fetus (15.5 weeks) compared to fetuses of 20 to 28 weeks reported in the literature. The approach of these specific cases must be individualized. There have been no trials enough so we can't know with certainty which treatment is the best of all.

[Arterial thrombosis in ovarian hyperstimulation syndrome]. / Trombosis arterial en el síndrome de hiperestimulación ovárica.

Ovarian hyperstimulation syndrome is an iatrogenic complication of controlled ovarian hyperstimulation. Its features are excessive growth of the ovaries and leakage of fluid from the intravascular space with ascites, hypovolemia and electrolyte imbalance, inducing a state of hypercoagulability, which can cause arterial or venous thrombosis. Thromboembolic events are the less common complications but they are the most serious. We communicate the case of a 30 years old woman with history of primary infertility; she was in treatment with controlled ovarian hyperstimulation. The patient developed ovarian hyperstimulation syndrome and arterial thrombosis in the right femoral artery.

[Case report. Post cesarean section laparoscopic cholecystectomy for hydrocholecystitis]. / Colecistectomía laparoscópica poscesárea por hidrocolecisto. Reporte de un caso.

BACKGROUND: Acute cholecystitis is the second most common surgical emergency in pregnant women. Although laparoscopic cholecystectomy has been described previously in these cases, there is still controversy regarding the most appropriate moment in which to perform the procedure. OBJECTIVE: To describe the clinical presentation and management of a female with 36.6 weeks of pregnancy and clinical signs of acute cholecystitis. Cesarean section to deliver a healthy newborn was immediately followed by laparoscopic cholecystectomy without complications. A 10 year literature review complements the analysis and discussion of the case. CLINICAL CASE: A 33 year-old female with 36.6 weeks of gestation presented a history of 24 hours with right upper quadrant and epigastric abdominal pain, nausea and vomiting. Symptoms were precipitated by cholecystokinetics and did not subside after expectant and pharmacologic medical treatment. The medical group decided with the patient's consent to interrupt the pregnancy via Cesarean section immediately followed by laparoscopic cholecystectomy. RESULTS: After Cesarean section through a Pfannenstiel incision, laparoscopic trocars were placed and cholecystectomy performed without complications. The postsurgical course was favorable and both patient and newborn were discharged on day four. CONCLUSIONS: Laparoscopic surgery cholecystectomy during pregnancy and in the immediate puerperium is feasible and safe. These combined procedures: rapid pregnancy interruption followed by a minimal invasive approach gives the benefits of laparoscopic surgery in these patients.

[Results' analysis of estradiol and progesterone supplementation in luteal phase vs progesterone alone in an assisted reproduction program]. / Análisis de los resultados de la administración complementaria de estradiol y progesterona en la fase lútea contra progesterona sola en un programa de reproducción asistida.

OBJECTIVE: To correlate estradiol and progesterone concentrations in luteal phase with pregnancy rates, and to determine the real value of estradiol administration during luteal phase support. PATIENTS AND METHODS: In a prospective and comparative study, 69 patients who underwent IVF-ET program were divided in two groups: group 1 (n = 32) received luteal phase support only with progesterone and group 2, (n = 37) luteal phase support with estradiol and progesterone. Ovarian stimulation was made with recombinant FSH and GnRH analogues (agonists or antagonists) and 24 hours after oocyte retrieval we began luteal phase support: group 1 progesterone (in oily solution) 100 mg/day IM, and group 2 same progesterone doses plus 2 mg of estradiol valerianate. Statistical analysis was performed using students' t- test and ROC curves. RESULTS: No statistical differences were observed in age, preovulatory estradiol levels, oocytes retrieved, fertilization rates, number of embryos transferred, or difficulty of embryo transfer among groups. The overall pregnancy rate was of 34.78% per cycle, no significant differences were observed among groups (37.5 vs 32.43%). We observed greater incidence of miscarriage in group 2 (4.35 vs 0%), without statistical significance. When comparing estradiol levels and pregnancy outcomes, higher levels were observed in the pregnancy group (403.3 vs 221.85 pg/mL) on day 7 post-transfer. Same results were reported for progesterone levels (107.04 vs 240.76). We determined that estradiol levels on day 7, higher than 244 pg/mL, could predict pregnancy with sensitivity of 58% and specificity of 70%, whereas progesterone levels greater than 108.6 ng/mL had specificity and sensitivity of 50 and 70%, respectively. CONCLUSIONS: We couldn't determine any advantage with estradiol supplementation during luteal phase support; however, measurement on day 7 of estradiol and progesterone allowed a greater predictive accuracy of pregnancy outcome.

[Conservative management of secondary ectopic abdominal pregnancy. Case report with literature review]. / Manejo conservador del embarazo ectópico abdominal secundario (intersticial). Informe de un caso y revisión de la literature.

Abdominal pregnancy is a rare condition representing 1-2% of all pregnancies; early diagnosis is difficult, but the challenge is the advanced pregnancy with adequate clinical condition for conservative management. There are few cases in which conservative management can improve, even though when the abdominal pregnancy is secondary to ruptured interstitial localization. A case of secondary (interstitial) abdominal pregnancy with conservative management and post-operative eventful for the mother and fetus is discussed.

Morbilidad materna en la adolescente embarazada / Maternal morbidity in adolescent pregnancy

OBJECTIVE: To evaluate the maternal morbidity in < or = 16 year old pregnant teenagers. MATERIAL AND METHODS: A prospective study of the reviewed cases was carried out from June 1998 to May 1999. All pregnant teenagers which attended the Coordination for the Attention of the Teenage Patient and whose pregnancy came to term during the study period were included. The following variables were analyzed: maternal age, preexisting related diseases, number of pregnancies, number of prenatal control medical visits and the time at which these were started, and maternal morbidity secondary to pregnancy. RESULTS: Two hundred and ninety six of 330 case were included. The average maternal age was 15.1 years old (10-16 range); 68.9 had finished middle school; 82.2 were housekeepers, and 61.4 were single. Prenatal control was initiated in the 2nd trimester by 50.7 of them, while 39.5 started it in the 3rd trimester and the remaining 9.8 in the 1st trimester. The most frequent previous pathologies were: bronchial asthma (2.5), drug addiction (2), hypothyroidism (2), cardiopathy (1.5). The most common complications during pregnancy: urinary system infections (20.4), anemia (9.8), threats of premature labour (9.8), premature membrane rupture (9), hypertensive disease induced by pregnancy (3.2), delayed intrauterine growth (2.4) and fetal malformation (2.4). About 44.1 of the pregnancies were interrupted by cesarean section, 35.6 by eutochia and 20.3 by instrumented labour. The most frequent complications during the puerperium were: tearing of the canal of the cervix (7), decidual endometritis (3.3), dehiscence of surgical wounds (2.7), and pyelonephritis (1.6). CONCLUSIONS: The pregnant teenager is a "special" patient form the biopsychosocial point of view, thus, she must be managed by a multidisciplinary team, with special emphasis in the problems analyzed in this study.

[Emergency cerclage]. / Cerclaje du urgencia.

OBJECTIVE: To evaluate the maternal and fetal morbility as well as the odds and conditions of pregnancy when performing an emergency cerclage. MATERIAL AND METHODS: We performed a transversal, prospective and descriptive study of all the patients to which an emergency cerclage was performed in the Instituto Nacional de Perinatología between January 1, 1995 and December 31, 1996 having all the inclusion criteria. At such time 261 cerclages were performed in our Institute upon unique pregnancies being only 22 considered as emergency cerclages. We performed studies of their obstetrics background, their incidental as per their age group, complications during the inclusion for the technique used as well as restitution of fetal membranes, complications before, during and after surgery: as well as the time elapsed as from the inclusion of the cerclage to birth and the data of the new born. RESULTS: 21 patients had previous pregnancies and only one of them was her first one; only 6 of their children were alive. The average age was 29.5 +/- 3.8 years and the gestational average age of the inclusion of the procedure was of 18 +/- 2.6 weeks, having a cervical dilatation of 2.5 cm +/- 0.9 cm. In 10 patients we had to restitute fetal membranes. The long extended average time between the colocation of the cerclage and labor was 66.8 days (more than 9 weeks) and the 86.4% of the resolution was via vaginal. CONCLUSIONS: It was observed that with the inclusion of the urgency cerclage we were able to prolong gestation in around 66 days, in which the main indicator of the perinatal forecast was the presence of fetal membranes or if they were bulging through internal cervical os. In this type of patients there is a major risk of having preterm labor and infectious maternal morbility. Notwithstanding that we believe that it is not an ideal procedure, the urgency cerclage has a place in current obstetrics. Prior to performing this procedure, we will have to study the patient as well as to have an adequate neonatal service.

[Perinatal outcome in patients with meconial amniotic fluid in labor]. / Resultado perinatal en pacientes con líquido amniótico meconial durante el trabajo de parto.

PURPOSE: To evaluate the perinatal morbidity and mortality with the presence of meconial amniotic fluid. MATERIAL AND METHODS: Retrospective study of case review, performed from 1st of June 1995 to May 1997. The patients included were at delivery, with a pregnancy of 32 weeks or older and had meconial amniotic fluid. The variables analyzed were: motherhood age, pre-existing associated illness, resolution of the pregnancy, PSS interpretation, fetal weight, Apgar and final destiny of the product. RESULTS: Of the 432 patients the motherhood aged varied from 13 to 43 years old, mean 27.4; with a number of pregnancies from 1 to 10, mean 2.25. The gestational age went from 32.2 to 42.4 weeks. The fetal weight varied form 1025 to 5080 g. The Apgar grade mean was 7 at the first minute and 8 at the fifth. The pregnancy was interrupted by cesarean in 52.5%. Although there was not a significant difference with the arterial gas, the density of the amniotic fluid did determine the final destiny of the product. CONCLUSIONS: There is a relation between the presence of amniotic fluid and the Apgar grade; both determining the final destiny of the product. When the amniotic fluid had thick meconium the products had a greater morbidity.

La cirugÝa pÚlvica como un marcador predictivo de la respuesta folicular a los inductores de ovulación / Pelvic surgery as a predictive marker of the follicular response to ovulation inducers

OBJECTIVE: Comparing the follicular response in a group of patients with previous pelvic surgery submitted to in vitro fertilization. MATERIAL AND METHODS: Patients who were going to be submitted to controlled ovarian stimulation and in vitro fertilization were included. Two groups were formed: one with those patients who had had a previous pelvic operation and the other with those patients who had not. The characteristics which were analyzed included: age, weight, body mass index, FSH, LH and estradiol levels, as well as total ova numbers, grade of embryonic maturity, and number of transferred embryos. RESULTS: Ninety nine patients were studied: 46 had been submitted to pelvic surgery and 53 had not. Due to the design of the study there were no differences regarding age, weight, size and body mass index; the evaluation of the ovarian reserve was similar in both groups. However, the group of patients previously submitted to pelvic surgery presented a lower quantity of total ova (p = 0.004), less mature ova (p = 0.008) with a significantly lower pregnancy rate. CONCLUSIONS: Surgical procedures, combined with adherence processes, probably have a direct incidence on the characteristics of the perifollicular environment which interfere with adequate development of the ovum. All these can be observed in a decrease of fertilization processes and embryonic development, regardless of the expression of the adequate biochemical markers of the ovarian reserve. Our research shows that the group under study presents a decrease in follicular response affecting the quality of the ovum-embryo expressed in the pregnancy rate.

Cesárea de repetición: ¿Una cesárea necesaria? / Repeated cesarean section: A necessary cesarean?

El objetivo es analizar las indicaciones clínicas de la cesárea de repetición (CDR), para determinar si su indicación fue absoluta o relativa y establecer si fue innecesaria. Se trata de un estudio transversal de revisión de casos, realizado de enero de 1996 a diciembre de 1997. Se incluyen todas las pacientes con antecedente de una cesárea previa a las cuales se les realizó CDR. Se excluyen embarazos múltiples. Se formaron dos grupos en cuanto a indicación: absoluta y relativa. Para la evaluación de las diferencias entre grupos se utilizó X2 Pearson y Prueba exacta de Fisher. Se incluyen 641 de 664 casos. La frecuencia de CDR fue de 11.9 por ciento. Edad materna promedio: 30 años, 57.2 por ciento no presentaron morbilidad durante el embarazo y 42.7 por ciento presentaron alguna patología (preeclampsia, diabetes mellitus/gestacional, hipertensión crónica). De las indicaciones de la primera cesárea 25.9 por ciento fueron absolutas y 74.1 por ciento relativas (p = 0.0006). Las indicaciones de la CDR fueron 29.3 por ciento absolutas y 70.7 por ciento) relativas (p = 0.00000). De las principales indicaciones de CDR fueron: electiva (20.1 por ciento), DCP (17.8 por ciento), preeclampsia (15.4 por ciento), compromiso fetal (8 por ciento). Se realizó prueba de trabajo de parto en 65.4 por ciento de las indicaciones absolutas y en 36.9 por ciento de las relativas (p = 0.0001). El Apgar bajo al minuto y cinco minutos fue más frecuente en las indicaciones absolutas que en las relativas (p = 0.03 y 0.01 respectivamente). El ingreso a terapia intensiva neonatal fue de 53.6 por ciento en las absolutas y de 46.4 por ciento en las relativas (p = 0.001).La principal indicación de la cesárea de repetición es relativa, por lo tanto su sustento resulta discutible.

Embarazo abdominal experiencia institucional / Abdominal pregnancy. Institutional experience

El embarazo abdominal es una entidad rara, la cual se ha clasificado como primaria o secundaria, basados en los criterios de Studiford. Se realizó una investigación retrospectiva de enero de 1989 a dicembre de 1994, en el Instituto Nacional de Perinatología. En este periodo hubieron 35080 nacimientos de los cuales 149 fueron embarazos ectópicos y seis de estos abdominales. Todas las pacientes se catalogaron como de estrato socioeconómico bajo, con un rango de edad de entre 24 y 35 años, con un promedio de gestaciones de 2.6 La edad gestacional osciló entre 15 a 32.2 semanas, obteniéndose un solo neonato vivo el cual evolucionó satisfactoriamente. Un caso curso con embarazo abdominal recurrente, quien tenía como antecedente tuberculosis genital. La estancia hospitalaria varió entre cuatro y cinco días. No se informaron complicaciones graves. La mortalidad fetal fue de 83.4 por ciento y cabe señalar que en todos los casos la placenta se extrajo completamente. El embarazo abdominal es generalmente consecuencia de un embarazo tubario y posee una alta mortalidad materna, aunque en nuestra serie no se observó ningún caso. La frecuencia citada varía desde uno en 3372 nacimientos hasta uno de 10,200, siendo nuestra frecuencia de uno por cada 5846 nacimientos y una proporción de 4 por ciento de todos los embarazos ectópicos, estando éste en el límite superior informado. Los datos clínicos más frecuentes fueron dolor abdominal, sangrado trasvaginal y amenorrea, refiriendose a éstos como la triada clásica del embarazo ectópico. Cabe señalar que encontramos dos eventos poco frecuentes, uno la recurrencia del embarazo abdominal y el otro la supervivencia de un producto

Embarazo cornual / Cornual ectopic pregnancy

El embarazo cornual es una entidad rara, presentada en 2 a 4 por ciento de todos los embarazos ectópicos, con una incidencia de uno en 2500 a 5000 nacidos vivos. Este cuadro es de importancia por su alta morbilidad y mortalidad materna. Principalmente por la distensión y ulterior ruptura de la cona intersticial en embarazos con edad gestacional avanzada que por lo general llegan a la semana 12 o 16. Suele provocar descompensacion hemodinámica importante. El diagnóstico debe basarse en el cuadro clínico similar al de todo embarazo ectópico, y la oportuna evaluación ecosonográfica es una ruta diagnóstica de valor. Se realizó una investigación retrospectiva de enero de 1989 a diciembre de 1994 en el Instituto Nacional de Perinatología, encontrandose 6 casos de embarazo cornual de 35 080 nacimientos, y de 149 casos de embarazo ectópico en general. Las variables investigadas fueron edad, antecedentes gineco-obstétricos, edad gestacional al momento del diagnóstico, cuadro clínico, manejo quirúrgico, complicaciones, estudio histopatológico y estancia hospitalaria. Edad materna de 29 a 35 años con un promedio de 31.5 años, gestacionales de 1 a 3 con media de 2 gestas. La edad gestacional al momento del diagnóstico osciló entre 7.1 y 24 semanas. El 100 por ciento de los casos presentó dolor abdominal difuso y amenorrea, en dos casos se informó sangrado transvaginal ameritando en todas las pacientes histerectomía total abdominal. La complicación más grave informada fue el choque hipovolémico (2 casos), sin encontrar mortalidad materna. El promedio de estancia hospitalaria fue de 5 días. En nuestra institución esta patología tiene una incidencia de uno por cada 5846 nacimientos, lo que equivale al 0.01 por ciento. De todos los embarazos ectópicos nuestra incidencia de embarazo cornual representa el 4.02 por ciento, lo cual nos sitúa dentro de lo comunicado en la literatura mundial
