Indicators of Internal Homeostasis in a Clinical Case Foetus in Fetu

Abstract

Blastopathy is a pathology that occurs during the blastula period, within the first 15 days from the moment of fertilization until embryo- and trophoblast ejection. Etiology of blastopathy is often unclear. This malformation is a variant of conjoined twins and
occurs with a frequency of 1: 500,000 deliveries. Our article presents the clinical case of “Foetus in Fetu” in the practice of the Scientific Center of Pediatrics and Children Surgery, Almaty, Republic of Kazakhstan. Newborn A was delivered from the perinatal centre on the 10th day of life. Prenatally, the ultrasound investigation of the foetus at the gestational age of 27–28 weeks diagnosed “pseudoomphalocele, ascites”. Mother was counseled by the geneticist on the recommended abortion, but she refused. At the age of 9 days the child was transferred to the Scientific Center of Pediatrics and Pediatric Surgery, where he was diagnosed as: congenital malformations, blastogenesis violation, asymmetric parasitic omphalopagus, foetus in fetu, congenital heart disease, interatrial septum defect (complete), globular heart, right-sided pneumonia, respiratory failure 1st stage, ischemic encephalopathy 2nd stage, prematurity 35–36 weeks and morphofunctional immaturity. The visible part of the
parasitic foetus is presented with torso, pelvis, two lower limbs, vestigial appendage – the only “arthrogrypose” upper limb. On the basis of the clinical data, it was suggested that the parasitic foetus and the main foetus have a single blood circulatory system. A certain interest, in our opinion, was the study of changes in the homeostasis parameters of this patient, as the vital organs were single to both organisms.
