Percutaneous and surgical interventions
on vessels often results in distal embolization of atherosclerotic debries
downstream. This is usually silent, however, in saphenous
vein interventions, carotid
interventions, and possibly renal artery stenting distal embolisation
may results in clinically significant events including myocardial infarction,
stroke, and renal failure. Embolic protection devices trap blood and
suspended debris in the body of the saphenous vein graft (occlusion
balloons) or trap debris (baskets) during stenting, allowing their evacuation
before unobstructed flow is restored. These devices are used in saphenous
vein grafts, carotids,
and renal arteries as well as venous thromboembolic disease.
A recent use of IVC filters for embolic protection during venous throbectomy and stenting. Below is a case of May Turner syndrome with thrombotic occlusion of left iliac vein treated with thrombectomy, Ultrasound facilitated lysis and stenting followed by removal of IVC filter used for embolic protection during procedure.
