Aortocaval compression syndrome, or supine hypotensive syndrome, is a pregnancy complication where lying flat on the back causes low blood pressure. Understanding its risks and management is crucial for maternal and fetal well-being.

Area of Science:

  • Obstetrics and Gynecology
  • Anesthesiology
  • Cardiovascular Physiology

Context:

  • Aortocaval compression syndrome (ACS), also known as supine hypotensive syndrome (SHS), is a frequent complication in late pregnancy.
  • Symptoms range from mild complaints to severe maternal hypotension, cardiovascular collapse, and fetal distress.
  • Supine positioning during diagnostic or therapeutic procedures, particularly cesarean sections, increases ACS risk due to multiple coinciding risk factors.

Purpose:

  • To review the pathophysiology, risk factors, and predisposing anesthesiological procedures of ACS.
  • To outline prophylactic measures and therapeutic options for managing ACS.
  • To present a clinically applicable algorithm for addressing ACS.

Summary:

  • ACS occurs when the gravid uterus compresses the aorta and inferior vena cava in the supine position, impairing venous return and cardiac output.

  • Risk factors include gestational age, maternal obesity, and specific anesthetic techniques.
  • Management involves immediate left uterine displacement, fluid administration, and vasopressors if necessary.

    • Impact:

    • Improved understanding of ACS pathophysiology and risk factors for healthcare providers.
    • Enhanced clinical practice through evidence-based prophylactic and therapeutic strategies.
    • Reduction in maternal and fetal complications associated with supine positioning during pregnancy.
