Abstract
Trisomy 18 is an autosomal chromosomal disorder characterized by the presence of an extra 18 chromosome. In the last decades, and as the therapeutic options have become more relevant, the medical community witnessed a paradigm shift on the offer of treatment to these children.This is a retrospective, cohort study that strives to characterize the clinical path and survival of the children with the diagnosis of trisomy 18, accompanied in a tertiary pediatric hospital between 1995 and 2020.Six children were identified with trisomy 18, two of them mosaic (33,3%) and four were females (66,7%). All had cardiovascular, cognitive and physical development anomalies or minor congenital anomalies (n=6, 100%) and most presented musculoskeletal anomalies (n=5, 83,3%) and feeding difficulties (n=4, 66,7%). Four children (66,7%) were reliant on devices or equipment and all needed chronic medication (n=6, 100%). Two children (33,3%) were submitted to surgical interventions. Four children (66,7%) were hospitalized in the last year of life. A decision of limitation of therapeutic effort was present in three cases (50%) with one child being referenced to pediatric palliative care (16,7%). One-month, one-year and ten-year survival were 66,7% (n=4), 33,3% (n=2, both mosaic), and 16,7% (n=1, mosaic) respectively.Conclusions: Knowledge on the clinical picture is of great importance regarding the neonatal care and the decisions about invasive treatments, which can involve ethical issues, highlighting, concurrently, the need for attempted referral of these children to pediatric palliative care teams.
