Vascular patency of fibular free graft: assessment by Doppler color-flow imager: a case report.

Viability of a vascularized free fibula transfer can be difficult to establish. It is possible, however, to assess patency of the involved microvascular anastomoses and blood flow in the vessels of the transposed fibula. A Doppler color-flow imager can be used to evaluate blood flow and vascular patency. The imager potentially can be employed in the operating room, during the immediate postoperative period, and for long term follow-up. It is non-invasive and produces a permanent record of vascular anatomy and flow characteristics.
