Angioplasty and stent insertion is carried out using the live images that are displayed on a television screen to guide the procedure.Ĭardiologists (doctors specialising in disorders of the heart) carry out stent insertions into the coronary (heart) arteries. Without contrast injection, blood vessels are invisible on X-rays. Less commonly, you may need to have the skin puncture in your upper arm, if the blood vessel in the groin cannot be used.Ī liquid contrast agent (sometimes referred to as contrast medium or dye) is injected into the artery to show the blood vessels on an X-ray image. Most often, the skin puncture is in the groin, at the top of the leg. Methods and results: We reviewed patients who underwent UHP angioplasty of in-stent or peri-stent PA stenoses that were resistant to high-pressure redilation. The procedure starts with an angiogram and is carried out through a skin puncture into the blood vessel that feeds the narrowed or diseased vessels. Angioplasty with ultra-high-pressure (UHP) balloons may facilitate successful treatment of stent-associated PA stenoses that are resistant to high-pressure dilation. The OPN NC super high-pressure balloon (SIS Medical AG) is a rapid exchange percutaneous transluminal coronary angioplasty. Although other angioplasty balloons are capable of generating high pressures and were used for stent redilation during this time period, previous experience and data suggest that angioplasty with UHP balloons is effective in relieving obstructions resistant to high-pressure dilations. Angioplasty is the name of the procedure carried out with the assistance of an angiogram, a special kind of X-ray image or picture that shows the arteries live on a screen. The stent is a small, metal cylinder that acts like a small scaffold to hold the artery permanently open. Angioplasty uses a small, sausage-shaped balloon to stretch the artery open and improve blood flow. percutaneous transhepatic cholangiogramĭr James Burnes* What is an angioplasty and stent insertion?Īngioplasty and stent insertion is used to treat narrowing in an artery.
