Fetal and neonatal thrombocytopenia

Area of Science:

• Perinatology
• Hematology
• Neonatology

Background:

• Thrombocytopenia, defined as a platelet count below 150,000 plat/mm3, presents diverse etiologies including immunological, infectious, and genetic factors.
• Understanding fetal thrombocytopenia often stems from fetal blood sampling, while neonatal thrombocytopenia is typically identified through blood counts prompted by infection risk.

Purpose of the Study:

• To review the causes and consequences of fetal and neonatal thrombocytopenia.
• To highlight the critical importance of early diagnosis and in-utero management for preventing intracranial hemorrhage.

Main Methods:

• Review of existing literature on fetal and neonatal thrombocytopenia.
• Discussion of diagnostic approaches including fetal blood sampling and neonatal blood counts.
• Emphasis on management strategies such as cordocentesis and platelet transfusions.

Main Results:

• The most severe complication is intracranial hemorrhage, which can occur as early as 18 weeks gestation.
• Early diagnosis and treatment, including in-utero interventions, are crucial for perinatal prevention of intracranial hemorrhage.

Conclusions:

• Fetal and neonatal thrombocytopenia require prompt recognition and management to mitigate risks.
• Advanced techniques like ultrasound-guided cordocentesis and platelet transfusions are vital in managing these conditions.
• Continued research and technological advancements are expected to further clarify diagnosis and treatment strategies.
