Определение stents в Английский Язык Английский Язык словарь
(endovascular, endobronchial or tracheal) Cylindrical metal devices that are placed on a balloon catheter, and are used to enlarge narrowed areas of blood vessels or the airway When expanded, stents have the appearance of a "chicken wire" cylinder, and resist collapsing When non-expanded, the stents are long and thin Endobronchial stents are used inside the airways (trachea) and endovascular stents can be used in blood vessels (pulmonary arteries or veins, major systemic veins, atrial baffles, or coarctation of the aorta)

A stent is sometimes used during angioplasty to hold open the dilated blood vessel after angioplasty (see above) It is effective in decreasing recurrent obstruction (restenosis) of the blood vessel following the procedure Ventricle -- Pumping chambers of the heart
A hollow plastic tube into the urinary tract prior to lithotripsy This tube is called a J-J stent One end of the stent coils up in the kidney, and the other coils up in the urinary bladder
A tube made of metal or plastic that is inserted into a vessel or passage to keep the lumen open and prevent closure due to a stricture or external compression Stents are commonly used to keep blood vessels open in the coronary arteries, into the esophagus for strictures or cancer, the ureters to maintain drainage from the kidneys, or the bile duct for pancreatic cancer or cholangiocarcinoma
This is a short, expandable tube manufactured to serve as a coiled metal scaffolding that is inserted into a narrowed artery The tube is expanded at the point of narrowing in the hope of keeping the walls apart Unfortunately, the blood within the tube often clots, or tissue overgrowth will fill the tube and block it, or the stent may move downstream
A device made of expandable metal mesh that is placed at the site of a narrowed artery The stent is expanded, using a catheter, and left in place to keep the artery open
Hollow wire mesh placed inside a blood vessel during a percutaneous coronary intervention Opening the stent within an artery presses the plaque against the artery wall and helps maintain an open lumen
An expandable, slotted metal tube, inserted into a vessel A stent acts as a scaffold to provide structural support for a vessel A drug-coated stent allows for the placement of that particular drug at the stent implantation site
A device made of expandable, metal mesh that is placed (by using a balloon catheter) at the site of a narrowing artery The stent is then expanded and left in place to keep the artery open
{i} (Medicine) mold used to hold a skin graft in place during healing; thin tube inserted into a tubular structure (e.g. a blood vessel) to hold it open or remove a blockage
A stent is crimped onto a balloon catheter and advanced into position It is then expanded to the desired size to support the vessel wall and prevent spasm The stent is left in place and the catheter is withdrawn Stents are also used in carotid and leg vessels In some agencies, nurses evaluate the patient for any complications post-PTCA and remove the femoral sheath Using stents and drugs such as Plavix appear to prevent stent thrombosis The insertion site is monitored for hematoma formation and external bleeding Sudden chest pain, SOB, ectopy, or a decrease in level of consciousness all need immediate assessment and treatment
