[Rare forms of feto-fetal transfusion in a clinical practice]. / Vzácné formy feto-fetální transfuze v klinické praxi.

OBJECTIVE: To analyze monochorionic twin pregnancies with twin anemia polycythemia sequence (TAPS) and acute peripartal twin to twin syndrome (aTTTS), to compare their prenatal management and perinatal outcome. METHODS: Retrospective analysis of monochorionic biamniotic twin pregnancies without signs of chronic TTTS within a period 10/2010 to 10/2013. Further selection of cases with haemoglobin difference in neonates greater than 50 g/l was made, type of feto-fetal haemorrhage was determined and their prenatal and postnatal characteristics were described. RESULTS: Based on the criteria described above we selected four cases out of 55 monochorionic pregnancies. One case of prenatally diagnosed spontaneous TAPS which fulfilled all the diagnostic criteria with typical angioarchitecture inclusive, one case of spontaneous TAPS diagnosed postnatally, a case of postlaser TAPS with a spontaneous resolution and one unusual case of feto-fetal haemorrhage which does not fully meet criteria of TAPS or aTTTS. All the pregnancies were delivered by caesarean section. All the anaemic neonates required blood transfusion postpartum and two of the polycythemic neonates needed partial exsanguination. CONCLUSION: Rare forms of feto-fetal transfusion syndrome form a heterogenous group and it may be difficult to distinguish between TAPS and aTTTS in certain cases. A recommendation for a management of TAPS cases was published in recent literature. However, correct interpretation of dopplerometric measurments belongs to the hands of experienced ultrasonographers in perinatal centers.

[Ectopia cordis - case report]. / Ektopie srdce - kazuistika.

OBJECT: Case report of ectopia cordis in a fetus at 23 weeks gestation. DESIGN: Case repor. SETTING: Obstetrics and Gynecology Clinic, University of Ostrava and University Hospital in Ostrava. METHODS AND RESULTS: We report a case of pentalogy of Cantrell variant in a 23-week fetus with an ultrasound finding of ectopia cordis, associated intracardial defects and omphalocele containing liver and guts. The patient opted for termination of pregnancy by using prostaglandins. Autopsy of the fetus revealed a cleft sternum and thoracic wall defect with nude ectopic heart-thoracic type and omphalocele containing liver and guts. Detailed examination of the heart revealed a double outlet right ventricle with a complete atrioventricular septal defect. Our study describes typical ultrasound findings in a correlation with autopsy findings. CONCLUSION: Ectopia cordis is a rare congenital malformation with an estimated incidence of 1:100 000 live births in developed countries. It is characterized by abnormal heart placement outside the thorax, mostly on the thoracoabdominal side. This form is often associated with pentalogy of Cantrell.
