Acardius mylacephalus: un diagnóstico poco frecuente / Acardius mylacephalus: an infrequent diagnosis

Se presenta el caso clínico de una primigesta de 21 años de edad, a quien se le detectó un embarazo gemelar monoamniótico y monocigótico en el examen ecográfico en el Centro Provincial de Genética de Santiago de Cuba. El primer feto presentaba hidronefrosis bilateral predominantemente en el lado izquierdo, y el segundo estructura fetal rudimentaria y deforme, área cardíaca mal estructurada y latidos cardíacos solo arrítmicos y bradicárdicos, además de que no se definieron los órganos internos y todo se encontraba rodeado de linfangioma quístico grave con grandes quistes paravertebrales y un solo cordón umbilical con tres vasos. Lo descrito en la ecografía se corroboró con los resultados de la necropsia, lo cual se correspondió con la variedad Acardius mylacephalus

The case report of a 21 years primigravida woman is presented to whom a monoamniotic and monochorial twin pregnancy was detected in the echographic exam at the Genetic Provincial Center of Santiago de Cuba. The first fetus presented bilateral hydronephrosis predominantly in the left side, and the second rudimentary and deformed fetal structure, not well structured heart area and just arrhythmic and bradycardiac heart beats besides that the internal organs were not defined and everything was surrounded by severe cystic lymphangioma with big paravertebral cysts and a single umbilical cord with three vessels. Everything described in the echogram was corroborated with the results of the autopsy, which corresponded with Acardius mylacephalus variety

Síndrome de perfusión arterial retrógrada en gemelos (trap): feto acardio: reporte de un caso / Reversal arterial perfusion syndrome in twins (trap): acardiac fetus: case report

Se presenta el caso de una paciente de 23 años de edad, procedente del Estado Barinas, II gesta, la cual presenta un embarazo gemelar monocorial, donde el primer feto tuvo desarrollo normal y falleció por dificultad respiratoria en el período neonatal y el segundo, fue un feto acardio anceps. Al examinar el feto se observó ausencia de corazón y pulmones, cerebro rudimentario y anomalías de las extremidades. La disección reveló epidermis con abundantes células vacuolizadas, dermis edematosa y ausencia del epiplón mayor. Los genitales externos femeninos estaban bien desarrollados. El examen radiológico mostró un cráneo pequeño, osificación de columna vertebral y anomalías óseas de manos y pies. Se hizo una revisión de la literatura sobre acardia en los últimos 30 años

We presente the case of a 23 year old patient, from Barinas State, II gravida, with a twin monochorial pregnancy, a normal fetus who died for respiratory distress in neonatal period and the other one, was an acardio anceps. The acardius presented absence of heart and lungs, a rudimentary brain, and anomalies of extremities. The dissection showed epidermis with numerous vacuolized cells, edematous dermis and absence of mayor epiploon. The external female genitals were well developed. Radiological screening showed a rudimentary cranium and anomalies of the hands and feet. We reviewed the last 30 years of acardia literature

A Case of Acardiac Twin / 대한산부인과학회잡지

Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. This condition is characterized by the absence or rudimentary development of fetal heart, and associated with various anomaly. The presence of an acardiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. The principal perinatal problems associated with acardiac twinning are pump-twin congestive heart failure, maternal hydramnios, and preterm delivery. We recently experienced a case of acardius anceps associated with a normal male infant, so present with a brief review of the literature.

A Case Report of an Acardic Acephalic Twin / 대한산부인과학회잡지

Acardic twining is a rare congenital anomaly, usually in monozygotic twins. This condition is characterized by the absence or rudimentary development of fetal hear, and associated with various anomaly(especially with anecephalus). The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. We recently experienced a case of acardius acephalus associated with a normal term male infant, so present with a brief review of the literature.

Acardiac Fetus with Encephalocele: A case report

The acardiac fetus is a rare type of fetal monster in which, as the name implies, the heart is completely absent. Acardius occurs only in a pair monozygotic twin, and shows various other defects in addition to the absence of the heart. Our autopsy case is acardiac anceps. He weighed 1,980 gm and the height was 33 cm. The brain is poorly developed, 60 gm in weight and similar to reversed snowman (3.5x2.8x2.8, 1.5x1.5x1.3 cm). Encephalocele, 6 cm in diameter, was communicated with the brain by a tract which contains nervous tissue and primitive choroid plexus. The upper extremities were absent, while the vertebrae and lower extremities were relatively well developed. The heart, lungs, stomach, liver, and spleen were absent, but the kidney, genital organs and urinary bladder were present. The intestine was seperated into two segments which were blindly ended, 32 cm and 15 cm in length, respectively.

Holoacardius Hemisomus Acephalus: A case report

An autopsy case of holoacardius hemisomus acephalus is reported. She weighed 2,190 gm and the height was 38 cm. The head and upper extremities were absent, while the vertebrae and lower extremities were relatively well developed, but severely edematous. The heart, lungs, stomach, liver, spleen, and pancreas were missing, but the lower abdominal organs including kidneys, adrenal, urinary bladder, and genital organs were present. The intestine was blind-ended at jejunal level but opened into a normal anus. The umbilical cord had two arteries and one vein.
