Angioplasty tears in a plaque may lead to clotting?

  1. Feb 27, 2005 #1
    In angioplasty, balloon is inserted on catheer and expanded, causing flattening or tearing of the rigid atheromous plaque and thus allow the vessal to return to its shape, often aided by a stent. But surely, any tears in a plaque may lead to cloating? After all, this is what we usually worry about with atherosclerosis - thombus and emolus formation.

    Thanks. :smile:

    My understanding of the procedure is that the intent is not to dislodge the plaque, but to widen the opening through it. Though, I would guess dislodging the plaque such that it would cause an embolism elsewhere would be an adverse risk of the procedure.

    There is a layer of endothelial cells covering the plaque. It think the angioplasty works by tearing the rigid plaque so that the blood vessel can reshape itself, but the plaque will still be there although it will be broken up. The stent helps in keeping the bloodvessel open, often it is covered in chemicals to aids in recovery of the bloodvessel.
