The persistent hypoglossal artery, a rare embryological remnant connecting the internal carotid and vertebro-basilar systems, can cause complications during carotid surgery. This report details two cases and discusses diagnostic and surgical considerations.

Area of Science:

  • Neurology
  • Embryology
  • Vascular Anatomy

Background:

  • The hypoglossal artery is a transient embryonic vessel connecting the internal carotid artery to the vertebro-basilar system.
  • Normally, this artery regresses during fetal development.
  • Persistence into adulthood is uncommon but clinically significant.

Observation:

  • Two adult patients presented with a persistent hypoglossal artery.
  • Detailed case histories and diagnostic imaging findings were reviewed.
  • The anatomical course and variations were analyzed.

Findings:

  • Persistent hypoglossal artery can be identified through advanced neuroimaging techniques.
  • This anomaly presents unique challenges and potential risks during carotid endarterectomy.

  • Understanding its embryological origin is crucial for diagnosis.

    • Implications:

    • Awareness of the persistent hypoglossal artery is vital for neurosurgeons performing carotid artery procedures.
    • Preoperative diagnosis can prevent intraoperative complications and improve patient outcomes.
    • Further research into the clinical significance and management strategies is warranted.
