Cryoplasty For Blocked Arteries – Promising Miracle Solution!
Cryoplasty is an innovative procedure that is gaining increasing popularity as a miracle solution for treating Peripheral artery disease caused by blockages in the arteries that carry blood to the limbs (and as an example artery being blocked in leg).
Angioplasty, a relatively new procedure is conventional implemented to open different arteries to increase blood flow. For example, coronary angioplasty is performed for opening coronary arteries for reducing the risk of heart attack. This procedure can also be effective in opening carotid and peripheral arteries.
Although angioplasty (opening of the artery by inflating and bursting a balloon filled with salt water at the blocked site) is minimally invasive, it still can cause unpleasant side effects such as scarring of the artery wall. Re-closing of the opened artery and requirement of stent (small stainless steel tubes) placement to keep the artery open are often angioplasty risks. Other side effects can include infections and bleeding.
Cryoplasty which is shown to be more effective than angioplasty uses the same technique but instead uses a balloon filled with nitrous oxide to cool the blocked environment to -10 degrees Centigrade. Studies showed that extreme cold temperatures cause the arteries to dilate (become wider) uniformly and affect arteries’ muscle fibers reducing the artery wall damage and scarring.
Although direct clinical studies do not exist that support the fact that the procedure induces programmed cell death (reduces smooth muscles cells in number) which reduces the incidence of re-closing of the artery, several studies that compared re-closing episodes involved in both procedures confirmed that cryoplasty has significantly less percentage. Also, the procedure has very less percentage of people requiring the need for a stent placement compared to that of angioplasty.
After cryoplasty many patients report considerable improvement in leg pain while walking which is one of the most common blocked arteries symptoms of PAD. Because of all the benefits and minimal side effects of the procedure it is rapidly being implemented in hospitals for opening blocked arteries.
