was performed if the deployed stent showed a residual stenosis greater than 50% of its normal diameter.
Restenosis after stent placement is less frequent (2.7-14.9%)16,38 than after balloon angioplasty
alone (13-31%)39 resulting from neointimal pro-liferation, stent fracture, stent recoil and growth.
and, if needed, stent replacement are the major components of this technique.

Severely calcified neointima is occasionally undilatable by balloon angioplasty
only and may lead to resistant ISR, requiring rotational atherectomy [10, 11].
However, balloon angioplasty
and the introduction of endovascular stents provide more optimal options.,, Previous studies of balloon angioplasty
showed relatively higher initial success rates (50-60%) with low complications (6-10%).
"There is also the possibility that patients who are offered bypass surgery already have more serious circulatory and atherosclerotic problems and hence an increased risk of vascular dementia than patients who are referred to a balloon angioplasty
. A registry study is limited by the fact that it does not tell us anything about the cause of the observed association.
We sufficiently explained the final cause of acutely developed paralysis to the patient and his family and then discussed the choice of treatment: conventional surgery or balloon angioplasty
An 83-year-old female with bilateral renal artery stenosis and balloon angioplasty
and stenting bilaterally one year ago was found to have recurrent severe elevations in the blood pressure despite medical management.
The non-surgical procedure is similar to balloon angioplasty
, where an empty, collapsed balloon is passed over a wire into the membrane and then inflated to a bigger size, putting pressure on the membrane, forcing it to widen, allowing blood to pass through comfortably into the heart.
Samir Kapadia, MD, section head of Invasive/Interventional Cardiology at Cleveland Clinic, says drug-coated balloon angioplasty
is an important new development in the treatment of PAD.
In 5 patients a residual gradient was detected and re intervention was required in 7.8% patients with balloon angioplasty
