Percutaneous umbilical blood sampling (PUBS) allows fetal blood collection for diagnosing various conditions like infections and hematologic disorders. This safe, popular technique also enables in utero therapeutic interventions.

Area of Science:

  • Maternal-fetal medicine
  • Prenatal diagnostics

Background:

  • Percutaneous umbilical blood sampling (PUBS), or cordocentesis, is an advanced prenatal diagnostic technique.
  • It allows direct access to fetal blood for comprehensive analysis.

Purpose of the Study:

  • To introduce and detail the applications of PUBS.
  • To highlight its utility in diagnosing fetal conditions and guiding therapy.
  • To discuss its role in assessing fetal thrombocytopenia.

Main Methods:

  • PUBS involves obtaining fetal blood samples directly from the umbilical cord in utero.
  • The procedure is minimally invasive and performed under ultrasound guidance.

Main Results:

  • PUBS is valuable for diagnosing fetal infections, karyotype abnormalities, growth retardation, hematologic disorders, and metabolic conditions.

  • It provides crucial data on fetal blood status, aiding clinical management.
  • The technique is applicable for therapeutic interventions like intrauterine transfusions.

    • Conclusions:

    • PUBS is a safe and effective method for prenatal diagnosis and management.
    • Its expanding applications offer significant benefits in assessing fetal health and treating specific conditions, including thrombocytopenia.
