Arterial graft occlusion after total knee arthroplasty treated by prompt thrombectomy.

We describe the case of an 83-year-old woman with a patent extra-anatomic femoropopliteal bypass who developed graft thrombosis during total knee arthroplasty. Reperfusion was achieved as a result of prompt diagnosis and thrombectomy. Arterial graft occlusion is a rarely reported complication of total knee arthroplasty, although it can be limb-threatening.
