ABSTRACT

Thrombosis is an unusual complication after stent placement these days with the routine use of anti-platelet therapies. Often thrombosis occurs on the basis of dissection (sometimes unseen) proximal or distal to the stent, perhaps caused by the protruding shoulders of the balloon. Infrequently it is associated with a poorly deployed stent, again unseen. Poor runoff downstream to the stent can contribute to slow flow and then thrombosis. Likewise the patient can have a propensity to thrombosis which is not overcome by our current therapeutic manoeuvres.
