Assessment and Management of Pitting Edema in Pediatric Patients

Evaluation of Edema in Specialized Contexts

  • The American Academy of Pediatrics recommends using validated instruments, such as the Manco-Johnson instrument and the Modified Villalta scale, to score edema in children being evaluated for post-thrombotic syndrome following deep venous thrombosis, with edema receiving 1 point if mid-calf or mid-thigh circumference increases >1cm compared to contralateral extremity 1, 2
  • The Manco-Johnson instrument and the Modified Villalta scale are used to assess edema as part of a comprehensive evaluation, with the Modified Villalta scale scoring edema 0-2 based on severity 1, 2
