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

Could you explain what is atherectomy's benefit over angioplasty?

Could you explain what is atherectomy's benefit over angioplasty?

Heavy calcification: Angioplasty can't dilate some types of blockage because they're too heavily calcified. Atherectomy can be successful sometimes where angioplasty can't. ...Read more

What is atherectomy's benefit over angioplasty, if it is in fact better?

What is atherectomy's benefit over angioplasty, if it is in fact better?

Calcified blockages: Rotational atherectomy is used for very hard and calcified blockages. Its like a drill bit and strips away the calcium so an angioplasty or a stent can be deployed. Often without the atherectomy catheter u can't do a stent and a bypass would be neccessary. ...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. If this reveals a plaque in the artery accounting for the symptoms, the catheter can be exchanged for another type of catheter that can carry out the atherectomy. ...Read more

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

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. As far as long term effects, the usual patient for atherectomy does not have very good anatomy and that is primarily the reason atherectomy is used. Hard, calcified plaques are usually not amenable to other methods of angioplasty. There are many cases when atherectomy is combined with stenting which is usually a better outcome. ...Read more

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

Atherectomy is it better than bypass?

Atherectomy is it better than bypass?

No: Bypass if needed and possible is a better form of revascularization. To this day, and to the best of my knowledge, there have not been any studies that show angioplasty of any kind has a better long-term outcome than bypass surgery. ...Read more

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

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

It's just an option.: Vascular surgeons and their patients are often presented with a complex series of choices and operative approaches. There are always different approaches that can be taken. This includes minimally invasive techniques, open surgery, or hybrid approaches that combined both. I use the approach you mention when patients do not have any vein for a bypass and have pain at rest. Can be effective. ...Read more

Can you tell me how atherectomy deal with severe peripheral arterial disease?

Can you tell me how atherectomy deal with severe peripheral arterial disease?

Removing plaque: Atherectomy is the removal of plaque build up in the lining of an artery. The plaque causes a narrowing of the arterial lumen decreasing blood flow. By removing the plaque, there is increased flow in that artery. It can be done by a variety of techniques: using a laser, or devices that act like a plane to shave the plaque and others that are like a drill or file. ...Read more

Is it possible that atherectomy open a totally occluded leg artery or just a leg artery that has narrowed considerably?

Is it possible that atherectomy open a totally occluded leg artery or just a leg artery that has narrowed considerably?

100% Vs: If totally occluded (100% blocked) and it's chronic it can't be opened. If it's 99% blocked and a guide wire can be placed across the blockage, it may be possible to open the artery using angioplasty or atherectomy. If the vessel can't be approached or is too tortuous or peripheral intervention, it may be possible to bypass it with open surgery. ...Read more

Could atherectomy work better on badly diseased leg arteries better then heart arteries?

No: There's really no comparison between atherectomy for heart arteries versus arteries in the extremities. Although both are caused by plaque or hardening of the arteries the treatment and intervention are vastly different. ...Read more

Is vascular lithotripsy on a femoral lesion an effective and safe means of plaque ablation? Any better than atherectomy or endarterectomy?

Is vascular lithotripsy on a femoral lesion an effective and safe means of plaque ablation? Any better than atherectomy or endarterectomy?

No: There is no role for lithotripsy in the treatment of peripheral arterial disease. Lithotripsy is a procedure primarily designed to break up kidney stones. If the procedure were used on arteries, the fragments might break off and further damage arteries downstream. The treatment for atherosclerotic related arterial disease includes medical management, the minimally invasive procedures you mentioned, and open procedures. Experienced vascular surgeons can offer all three methods. ...Read more

How effective is atherectomy for coronary artery disease?

How effective is atherectomy for coronary artery disease?

Very effective: Rotational atherectomy is a niche tool. Some kinds of coronary blockages are not amenable to stenting, particularly those which contain a large amount of calcium. These blockages are very hard and the stent cannot easily expand. Rotational atherectomy is very effective in opening heavily calcified arteries. Rotational atherectomy is not required in the majority of angioplasties. ...Read more

Coronary CT angiogram shows extremely high calcium score of 4242 and ~ 70% blockage one artery. Next step cath angio. Should I consider atherectomy?

Coronary CT angiogram shows extremely high calcium score of 4242 and ~ 70% blockage one artery. Next step cath angio. Should I consider atherectomy?

NO: You need a coronary angiogram-depending what it shows, you may need revascularization. Depending on location and extent, you may need surgery. Otherwise, balloon angioplasty followed by stenting is the treatment of choice. Atherectomy has a very limited and specific indication. If you need it, your interventionalist is the one to make the call. ...Read more
