NCT02449525

Brief Summary

The perfusion of microvascular free flaps is inevitable for completion of reconstruction in the head and neck area. In some patients microvascular anastomosis is impossible because of arteriosclerotic changes, different oncological interventions, and consecutive vessel depletion at the neck. The aim of the project is to establish an innovative system for extracorporeal perfusion of microvascular free flaps after ingrowth of new vessels from the wound bed have taken place. Afterwards, no further perfusion of the vascular pedicle is required for free flaps to survive and provide functional and aesthetic reconstruction.

Outcome Measures

Primary Outcomes (1)

  • Perfusion of Free Flap from wound bed

    Two Weeks

Study Arms (1)

perfusion of flaps by a bypass system

EXPERIMENTAL

Support of perfusion of microvascular free flaps until ingrowth of vessels from the wound bed has taken place. The System works with a pressure controlled bypass to ensure low grade perfusion.

Procedure: Perfusion of flaps by a special bypass system

Interventions

Free flaps are perfused via a special bypass perfused by a new technique supported by a intermittent perfusion support system.
