Clarification Required: These Measurements Appear to Be Foot Alignment Angles, Not Vascular Parameters

The values you've provided (M PTA = 88.5 degrees, L DFA = 83.5 degrees) appear to represent radiographic foot alignment angles used in orthopedic and podiatric surgery, not vascular measurements. Specifically:

  • M PTA (Meary's Posterior Tibial Angle) = 88.5 degrees
  • L DFA (Lateral Distal Femoral Angle or more likely Lateral Distal Fibular Angle) = 83.5 degrees

If These Are Foot Alignment Angles

These measurements are typically used to assess:

  • Flatfoot deformity (pes planus)
  • Hindfoot alignment
  • Surgical planning for foot reconstruction

The provided evidence focuses entirely on peripheral arterial disease, vascular surgery, and limb ischemia management, which is not relevant to orthopedic foot alignment measurements.

If You Meant Vascular Assessment

If you intended to ask about vascular parameters, please clarify:

  • Ankle-Brachial Index (ABI) values
  • Toe-Brachial Index (TBI) measurements
  • Transcutaneous oxygen pressure (TcPO2) readings
  • Doppler waveform patterns (triphasic, biphasic, monophasic)
  • Arterial stenosis percentages
  • Post-procedural angiographic findings

Request for Additional Information

To provide appropriate management recommendations, please specify:

  • What clinical question you're addressing (vascular vs. orthopedic)
  • Patient symptoms (claudication, rest pain, tissue loss, foot deformity)
  • What procedure was performed (if post-vascular intervention)
  • Complete vascular assessment data if this is a peripheral artery disease case
