Summary

Prompt identification and intervention are key to salvaging head and neck free flaps. Timely surgical revision and adjunct therapies improve outcomes for vascular compromise, with venous congestion being more salvageable than arterial issues.

Main Results:

Prompt identification and intervention are critical for free-flap salvage.
Surgical microvascular revision is the primary salvage strategy.
Venous congestion is more amenable to salvage than arterial insufficiency.
Adjuncts like thrombolytics and anticoagulation play a role.

Conclusions:

Vascular compromise of head and neck free flaps is a feared complication.
Successful salvage relies on prompt identification and intervention.
Timely and directed interventions are essential to re-establish perfusion.
