title: The role of vascular pedicle thrombectomy in the management of compromised free tissue transfers.
abstract: Microvascular free tissue transfer has become a very reliable reconstructive technique. Occasionally, flap compromise will occur and will require urgent flap reexploration. In the setting of complete thrombosis of pedicle vessels, thrombectomy using Fogarty #2 and #3 catheters can be effective in restoring vascular patency. Seven flaps with arterial, venous, or both vessel thrombosis were managed with thrombectomy at the time of reexploration and anastomotic revision. Six of the flaps were completely salvaged and the seventh was partially salvaged. Promptness in reexploration increased the likelihood of complete flap salvage. The use of postthrombectomy heparinization was associated with a 50% complication rat in this series. Thrombectomy of free flap vessels can be safely performed and is associated with a low incidence of rethrombosis.
