An unusual cause of femoral embolus.

Acute lower limb ischaemia is associated with high morbidity and mortality. The authors describe an unusual cause of arterial occlusion two weeks following aorto-coronary bypass surgery. This case should make vascular surgeons aware of the possibility of prosthetic materials acting as emboli. Furthermore, they should also be mindful that the presenting symptom may be at a site and time remote from the original intervention.
