What is the benefit of an atherectomy over an angioplasty?

Atherectomy v balloo: typically blocked arteries can be opened more widely by inflating a balloon inside the vessel. The balloon is then deflated and removed from the vessels. At times, heavy calcium makes the arteries so hard they won't open w/ the balloon. Some of those lesions can be addressed w/ Atherectomy, a device that shaves the plaque down creating a more wide flow channel. ...Read more

Is it possible for you to combine angioplasty and atherectomy procedures?

Yes: Angiography and atherectomy are both performed through the same approach, namely inserting a catheter into an artery, usually the artery at the groin. The angiography is performed first.

What must I expect in terms of effects having atherectomy for cad?

Same as angioplasty: This should not feel any different from a regular angioplasty.

Is atherectomy better than stent?

Is atherectomy better than stent?

Different : Atherectomy is not better than stenting, it usually is reserved for cases when a balloon angioplasty combined with stenting, or direct stenting can not be accomplished due to the plaque burden. In those cases atherectomy is used to debulk the plaque and the best result would be if this can then be supplemented with a stenting to prevent plaque regrowth or near-term closure of the vessel. ...Read more

Why have a femorsl endarterectomy when there are atherectomy procedures to consider instead?
