Vascular: Popliteal Artery Entrapment Syndrome (PAES)

Popliteal Artery Entrapment Syndrome (PAES)

Basics

  • Definition: Popliteal Artery Entrapped Under Calf Muscles
  • Presentation: Intermittent Claudication & Loss of Pulses with Plantar Flexion
  • Most Common in Male Athletes
  • Can be Bilateral

Heidelberg Classification

  • Type I: Popliteal Artery Deviated Medially by a Normally Situated Medial Head of the Gastrocnemius
  • Type II: Popliteal Artery Deviated Medially by an Abnormally Situated Medial Head of the Gastrocnemius
  • Type III: Popliteal Artery Deviated Medially by an Accessory Slip or Fibrous Band from the Medial Head of the Gastrocnemius
  • Type IV: Popliteal Artery Lies Deep to the Popliteus Muscle
  • Types V: Compression of Both Popliteal Artery & Vein by Types I-IV
  • Type VI: Entrapment without an Associated Anatomic Abnormality

Diagnosis

  • Diagnosis: Loss of Doppler Signal with Provocative Maneuvers & CT/MRI

Treatment

  • Primary Treatment: Myotomy
    • Typically Resect Medial Head of the Gastrocnemius
