ABSTRACT

Resumen ANTECEDENTES: Los linfangiomas fetales son malformaciones del sistema linfático que representan 4% de todos los tumores vasculares en los recién nacidos vivos, con una incidencia de 1.2-2.8‰. CASOS CLÍNICOS: Se comunican dos casos clínicos poco frecuentes, por su localización y extensión, de linfangiomas fetales. En ambas pacientes el diagnóstico se estableció mediante estudio ecográfico, durante el tercer trimestre, en gestaciones de bajo riesgo. La alteración no se relacionó con malformaciones estructurales adicionales, trastornos cromosómicos ni genéticos. La resonancia magnética confirmó el diagnóstico de la enfermedad. En una de las madres, el tamaño del feto determinó la vía de finalización del embarazo (parto). La cirugía fue el tratamiento de elección, con evolución satisfactoria en una paciente y la otra permanece a la espera de una nueva intervención quirúrgica, pues aún manifiesta recidivas. En la actualidad, el desarrollo psicomotor, ponderal y estructural de las pacientes es adecuado. CONCLUSIÓN: La ecografía es un estudio decisivo para establecer el diagnóstico y seguimiento de los linfangiomas fetales.


Abstract BACKGROND: Fetal lymphangiomas are malformations of the lymphatic system, representing 4% of all vascular tumors in living newborns, with an incidence of 1.2-2.8‰. CLINICAL CASE: Two uncommon clinical cases, due to their location and extension, of fetal lymphangiomas are reported. In both patients, the diagnosis was established by ultrasound study, during the third trimester, in low risk gestations. The alteration was not related to additional structural malformations, chromosomal or genetic disorders. Magnetic resonance confirmed the diagnosis of the disease. In one mothers, the size of the fetus determined the route of termination of pregnancy (delivery). Surgery was the treatment of choice, with satisfactory evolution in one patient and the other remains awaiting a new surgical intervention, because it still manifests recurrences. At present, the psychomotor, weigth and size development of the patients is adequate. CONCLUSION: Ultrasound is critical for diagnosis and monitoring of this type of malformations.

ABSTRACT

A case of in utero spondylothoracic dysostoses is diagnosed during a routine third trimester ultrasound scan in a low-risk patient. Ultrasound showed spine deformation, hemivertebrae and crab-like ribs. The newborn had no other associated anomalies except inguinal hernia, and karyotype was normal. Bidimensional and 3-4D ultrasound imaging as well as radiograph of the fetus and photos of the newborn are presented and discussed. Sporadic cases are difficult to diagnose and classify, as they are probably due to genetic heterogenicity. Sporadic cases of hemivertebrae are rare and not always lethal. Fetal ultrasound scan findings can help predict prognosis, enabling the parents' informed decision making.

ABSTRACT

AIMS: To assess the responsive fetal extremity movement to vibro-acoustic stimulation test (VAST). METHODS: The moving velocity of fetal femur was assessed after VAST by pulsed Doppler device. The ultrasonic beam was insonated at a right angle to the fetal femur. The following parameters were determined: limb retreat velocity in accelerative slope (Pk1); limb replenishment velocity in decelerative slope (Pk2); mean flexion to extension velocity; and the response time to VAST. Among 80 normal singleton pregnancies in 33-41 weeks, 68 were weekly evaluated and the others were assessed for two or more times during the study period, for a total of 680 studies of fetal kinetics. RESULTS: The Pk1 declined from 9.6 to 6.26 cm/s; Pk2 decreased from 2.6 to 1.3 cm/s; mean velocity was reduced from 6.0 to 4.25 cm/s; whereas the response time increased from 0.1 to 0.3 s throughout the study period, i.e., fetal response reduces and the response time increases as maturation progresses. CONCLUSION: The pulsed Doppler may assess fetal activity in any body structure. Reflex responses become slow and complex on both the velocity and response time as maturation increases with gestational age. Our observations have resulted in a novel and easy method for the quantitative assessment of fetal reflex reactivity to external stimuli.

ABSTRACT

Presentamos el diagnóstico prenatal de un caso de trisomía parcial del cromosoma 1 (1q25-qter) por translocación paterna en una paciente de 31 años, a la que se realizó amniocentesis para estudio cromosómico a las 16 semanas de gestación por la existencia de datos dismorfológicos ecográficos. Se efectúa un estudio necrópsico del feto y las anomalías encontradas se comparan con las referidas en otros casos de trisomía parcial del cromosoma 1


We report the prenatal diagnosis of a case of partial trisomy of chromosome 1 (q25-qter) due to paternal translocation in a 31-year-old patient. Amniocentesis for chromosomal analysis was performed in the 16th week of pregnancy because ultrasound examination had revealed certain anomalies. A necropsy of the foetus was carried out and the anomalies found were compared with those in other cases of partial trisomy of chromosome 1
