Insights
Trisomy 18 prognosis is poor, but prospective management is possible in select cases. Parental support, social factors, and medical interventions are crucial for improving outcomes in infants with Trisomy 18.
Area of Science:
- Medical Genetics
- Pediatric Cardiology
- Neonatology
Background:
- Trisomy 18 (Edwards syndrome) is often considered fatal, with limited treatment options.
- Recent advancements and parental advocacy have led to increased surgical interventions for Trisomy 18.
- This study examines the impact of evolving treatment approaches on prenatal and postnatal care.
Observation:
- Three infants with Trisomy 18 received specialized perinatal care.
- Interventions included surgical repair for congenital heart defects and diaphragmatic hernia.
- Supportive care involved nasal CPAP, feeding tubes, and management of pulmonary hypertension.
Findings:
- Despite poor prognosis, individualized prospective management allowed survival in these cases.
- All surviving children exhibit developmental delays and required ongoing medical support.
- No acute lethal malformations were present in these Trisomy 18 cases.
Implications:
- Individualized, prospective management can be feasible for Trisomy 18.
- Parental wishes, social support, and economic stability are critical factors in decision-making.
- Further research is needed to establish long-term outcomes and refine treatment strategies.
Background:
In current literature the prognosis of trisomy 18 is mainly described as inevitably lethal. After intervention of parental organisations infants have been treated with cardio surgery in the USA, later in Europe as well with good results. We report the consequences of this and similar developments on our pre- und postnatal approach after diagnosis in our department. PATIENTS AND CASE REPORTS: 2 parents decided to carry the child to term after the recommendation for abortion. According to standard perinatological aspects one child was vaginally delivered, the second with Caesarean section. After informed consent with the parents we planned a supportive management without more resuscitation than stimulation and ventilation by mask. Both children could be stabilised with nasal CPAP. The first one had been operated on a double outlet right ventricle at the age of 6 months, the second needed to be operated for diaphragm hernia. The third child had been delivered by emergency Caesarean section. A bilateral choanal atresia had been operated in the first week of life, a double outlet right ventricle at the age of 15 days. One child is fed by a nasogastric tube, one is bottle-fed and one had a percutanous gastric tube until he died due to septicaemia, all have statomotorically retardation and had periods of pulmonary hypertension. The social situation of the families is characterised by a stable parental relationship and a safe socio-economical status. None of the children had an acute lethal malformation.
Discussion:
In single cases a prospective management in patients with trisomy 18 can be possible. Besides medical issues, the emotional parental wish, their social network and economical status are crucial.
Conclusion:
The prognosis of trisomy 18 is poor. 3 patients and 20 months do not allow any general statements. However, our recent experience and the courses in the recent literature show that in single cases a more prospective management is possible.
