Pathway Overview

12 steps

Algorithm Steps

12 total

  1. 01Start

    Suspected Free Flap Compromise

    Change in flap appearance or signals

  2. 02Action

    Baseline Flap Monitoring

    Normal postoperative appearance

    • COLOR: Pink, matches recipient site
    • CAPILLARY REFILL: 1-2 seconds
    • TEMPERATURE: Warm to touch
    • TURGOR: Soft, non-tense
    • DOPPLER: Audible arterial signal
    • MONITORING FREQUENCY:
    • - Q1h x 24h, then Q2h x 48h
    • - More frequent if high-risk
  3. 03Warning

    Clinical Changes Detected

    Deviation from baseline

    • ALERT SIGNS:
    • - Color change (pale OR dusky)
    • - Capillary refill change
    • - Temperature change (cool)
    • - Turgor change (tense OR flaccid)
    • - Doppler signal change/loss
    • IMMEDIATE ACTION: Call attending
  4. 04Decision

    Type of Compromise?

    Arterial vs Venous vs Mixed

  5. 05Warning

    Arterial Insufficiency

    Inflow problem

    • CLINICAL SIGNS:
    • - PALE/WHITE flap
    • - Cool to touch
    • - Slow/ABSENT capillary refill
    • - Collapsed veins
    • - NO arterial Doppler
    • CAUSES:
    • - Thrombus
    • - Kink/compression
    • - Vasospasm
    • - Hematoma compression
    • TIME WINDOW: <6 hours optimal
  6. 06Action

    Immediate Bedside Interventions

    While preparing for OR

    • GENERAL:
    • - Remove all dressings
    • - Check for external compression
    • - Optimize positioning (elevate/lower)
    • - Warm room, warm blankets
    • FOR VENOUS:
    • - Leech therapy if available
    • - Pinprick bleeding every 30 min
    • - Heparin gauze
    • FOR ARTERIAL:
    • - Papaverine topically
    • - Warm saline compresses
  7. 07Action

    Pharmacologic Support

    Anticoagulation/vasodilation

    • HEPARIN (if not contraindicated):
    • - Bolus 5000 units IV
    • - Or therapeutic infusion
    • DEXTRAN 40 (controversial):
    • - 20 mL/hr if used
    • ASPIRIN:
    • - 325 mg daily if not on already
    • VASODILATORS (for spasm):
    • - Papaverine topical/intra-arterial
    • - Verapamil intra-arterial
    • - Nicardipine
  8. 08Action

    Operative Exploration

    Definitive management

    • TIMING: Within 2-4 hours of diagnosis
    • EXPLORATION:
    • - Inspect anastomoses
    • - Check for kink/compression
    • - Evaluate thrombus
    • THROMBECTOMY:
    • - Fogarty catheter
    • - Milking clot
    • REVISION:
    • - Re-do anastomosis if needed
    • - Vein graft if length issue
    • - Supercharged with additional vein
  9. 09Decision

    Salvage Successful?

    Post-revision assessment

  10. 10Outcome

    Flap Salvaged

    Continue close monitoring

    • Increase monitoring frequency
    • Continue anticoagulation
    • Optimize conditions
    • Watch for re-thrombosis
    • Salvage success rate: 50-80%
  11. 11Outcome

    Flap Loss

    Plan for reconstruction

    • Debride necrotic tissue
    • Wound care/VAC
    • Consider: Second free flap, local flap, skin graft
    • Timing: Delayed reconstruction
    • Total flap loss rate: 2-5%
  12. 12Warning

    Venous Congestion

    Outflow problem (more common)

    • CLINICAL SIGNS:
    • - DUSKY/PURPLE/BLUE flap
    • - Warm or cool
    • - BRISK capillary refill (<1 sec)
    • - DARK blood on pinprick
    • - Tense, swollen flap
    • - Arterial Doppler may be present
    • CAUSES:
    • - Venous thrombus
    • - External compression
    • - Kinking
    • TIME WINDOW: <12 hours (more forgiving)

Clinical Safety Information

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Clinical monitoring requires training
  • Buried flaps harder to monitor
  • Time windows are approximations
  • Success depends on operative expertise
