Abstract
INTRODUCTION: Despite high success rates with free-tissue transfer, flap loss continues to be a devastating event. Flap salvage is often successful if vascular complications are recognized and treated early. However, delayed presentation of flap compromise is an ominous predictor of flap loss. Late free-flap salvage has been described with poor long-term results. Catheter-directed thrombolysis (CDT) has only been described in context with free-tissue transfer in a case of distal bypass salvage. OBJECTIVES: The authors examined the efficacy of highly selective CDT in late salvage of free-flaps with vascular compromise. METHODS: Two patients underwent highly selective CDT after delayed presentation (>5 days) of flap compromise. Patient 1 is a 59-year-old woman who underwent delayed breast reconstruction with a free TRAM flap and presented with arterial thrombosis 12 days postoperatively. Patient 2 is a 53-year-old man who underwent fibular osteocutaneous free-flap reconstruction of a floor of mouth defect who developed venous thrombosis 6 days postoperatively. Patient 2 underwent two attempted operative anastamotic revisions with thrombectomies and local thrombolysis prior to CDT. RESULTS: The average time of presentation was 9 days, with the average time to CDT being 9.5 days. Patient 1 had an arterial thrombosis, whereas Patient 2 had a venous thrombosis. Both patients underwent successful thrombolysis after super-selective angiograms. Continuous infusions of thrombolytic agents were used in both patients for approximately 24 h. Average length of stay postCDT was 7 days with no perioperative complications. Long-term follow-up demonstrated complete flap salvage with no soft tissue loss. CONCLUSION: Despite extremely delayed presentation, aggressive CDT was successful in both breast, and head and neck reconstructions with excellent long-term flap results. CDT appears to be a useful modality in managing difficult cases of free-flap salvage. (c) 2008 Wiley-Liss, Inc. Microsurgery, 2008
