Diagram of stent placement. In A, the catheter is inserted across the lesion. In B, the balloon is inflated, expanding the stent and compressing the plaque. In C, the catheter and deflated balloon have been removed. Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation
Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents, a permanent wire-meshed tube, to open narrowed coronary arteries. PCI is considered 'non-surgical ...
PCI is a minimally invasive procedure. It involves the placement of a drug-eluting stent (DES) in a coronary artery. This procedure, previously known as angioplasty with a stent, is considered non-surgical as it is performed through a small puncture in a peripheral artery, avoiding the need to open the chest wall. While bleeding from the ...
Stenting refers to the placement of a stent. The word "stent" is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis has pathologically narrowed a structure such as an artery. A stent is different from a shunt. A shunt is a tube that connects two previously unconnected parts of the ...
A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
A percutaneous coronary intervention, or coronary angioplasty with stenting, is a non-surgical procedure used to improve the blood flow to the heart. [ 1 ] Coronary angioplasty is indicated for coronary artery diseases such as unstable angina , NSTEMI , STEMI and spontaneous coronary artery perforation. [ 1 ]
A prostatic stent is a stent used to keep open the male urethra and allow the passing of urine in cases of prostatic obstruction and lower urinary tract symptoms (LUTS). Prostatic obstruction [ 1 ] is a common condition with a variety of causes.
Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel through the healing process. However, in the case of a bioresorbable stent, the stent will gradually resorb and be benignly cleared from the body, enabling a natural reconstruction of the arterial wall and restoration of vascular function.
