Today, heart surgeons are able to realize yet what was unthinkable a few years ago: replace defective parts of the heart, adjust its beats, adapting new vessels, in short, offer a wide range of interventions tailored to each pathology. Is Doctissimo point on the techniques frequently used in hospitals and this therapeutic prospects offered by research.
Angioplasty or arterial dilatation
Since 1977, the angioplasty to restore normal blood flow in the arteries narrowed by plaque of atherosclerosis (build-up of cholesterol). It involves inserting into the clogged artery catheter end completed by a balloon, which once inflated, dilate the artery and allows recovery of blood flow.
But in the six months following this intervention, three complications may occur: an elastic recoil of the arterial wall decreasing its diameter, a proliferation of cells due to the healing of tissues and chronic vasoconstriction of the ship. This is what is called post-angioplasty Restenosis. You can then drop in a small wire mesh stent that such a spring, holds the artery open when the balloon is removed. It reduced the rate of Restenosis by 30% by limiting the elastic recoil and vasoconstriction, but it does not prevent cell proliferation. In this context, the use of ionising radiation could provide an effective solution. Continue reading “The prowess of the cardiac surgery”
