We present a case of siamese twins diagnosed by ultrasound as thoraco-omphalopagus joint fetuses, at Instituto Nacional Materno Perinatal (Ex Maternidad de Lima). We summarize the clinical history, necropsy protocol and present a short bibliography.

Objectives: To determine the frequency and type of intrauterine invasive procedures performed at a unit of fetal medicine and cytogenetic results, immediate complications and indications for chorionic villous sampling and amniocentesis. Design: Observational, retrospective and transversal type study. Setting: Fetal Medicine Unit, Instituto Nacional Materno Perinatal, Lima, Peru. Participants: Pregnant women who accepted an intrauterine invasive procedure. Interventions: Intrauterine invasive procedures in pregnant women were done for various reasons from April 2005 through April 2007. We determined each procedure frequency and compared cytogenetic results, indications and immediate complications of genetic amniocentesis and chorionic villous sampling. Main outcome measures: Characteristics of intrauterine invasive procedures, cytogenetic results and complications. Results: During the 25 ...

El síndrome costillas cortas polidactilia es una categoría descriptiva para un grupo de displasias esqueléticas incompatibles con la vida, caracterizadas por tórax estrecho, costillas extremadamente pequeñas, micromelia, polidactilia y anomalías viscerales. Las 4 variantes establecidas son SRPS I (tipo Saldino-Noonan), SRPS II (tipo Majewski), SRPS III (tipo Verma-Naumoff) y SRPS IV (tipo Beemer-Langer). Se piensa que todas las variantes son heredadas en forma autosómica recesiva. Debido a la frecuente superposición fenotípica, existe controversia si las variantes son debidas a expresión variable o a heterogeneidad genética. Presentamos un caso de un feto masculino, con signos ecográficos característicos de displasia esquelética, tales como micromelia, tórax estrecho en forma de campana, hipertelorismo, implantación baja de las orejas y polidactilia, que nació de parto v...

Background: The finding of short femur (length below the 5th centile) at second trimester ultrasound examination is a diagnostic challenge. Classically, the short femur has been associated to chromosomal abnormalities and skeletal dysplasias. A few reports have been published on fetuses with isolated short femur outcomes. Objectives: To determine perinatal outcomes in the second-trimester fetuses with isolated short femur and to determine its association with fetal growth restriction. Design: Retrospective cohort study, also called historical or concurrent study. Setting: Fetal Medicine Unit, Instituto Nacional Materno Perinatal, Lima, Peru. Participants: Women with 16 to 28 weeks pregnancies. Interventions: The sample size was drawn from our 2006-2008 databases and consisted in 278 fetuses 16 to 28 weeks who had ultrasound examination. We categorized two groups: fetuses with isolated sh...

Sacrococcygeal teratoma is a rare fetal disease but with high perinatal mortality due to sequestration of blood flow and consequent development of severe fetal anemia. We present the case of a 27 weeks pregnant woman referred to our service for prenatal management of a fetus with giant sacrococcygeal teratoma and severe anemia and who was subjected to intrauterine intravascular transfusion that could permit prolongation of the pregnancy and improve perinatal results.

Fetal ascites is defined as the presence of intraperitoneal fluid that may be part of a generalized or isolated hydrops. The mortality of non-immune ascites, both fetal and neonatal, is approximately 60%. We present a case of fetal ascites not associated with hydrops and we review the pathogenesis, clinical features, diagnostic approach and treatment of this fetal and neonatal condition.
