| laser angioplasty | <cardiology, procedure> A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an excimer laser which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (angioplasty, balloon, laser-assisted). (05 Mar 2000) |
|---|---|
| laser-assisted balloon angioplasty | <cardiology, procedure> Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1. Laser fibre delivering the energy while the inflated balloon centres the fibre and occludes the blood flow. 2. Balloon angioplasty immediately following laser angioplasty. 3. Laser energy transmitted through angioplasty balloons that contain an internal fibre. (05 Mar 2000) |
| angioplasty | <cardiology, surgery> The surgical repair of a blood vessel. A balloon angioplasty is a noninvasive procedure where a balloon-tipped catheter is introduced into a diseased blood vessel. As the balloon is inflated, the vessel opens further allowing for improved flow of blood. (12 Nov 1997) |
| angioplasty balloon | A balloon near the tip of an angiographic catheter, designed to distend narrowed vessels. See: balloon-tip catheter. (05 Mar 2000) |
| balloon angioplasty | <cardiology> Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, angioplasty, transluminal, percutaneous coronary is available. Coronary angioplasty is accomplished using a balloon-tipped catheter inserted through an artery in the groin or arm to enlarge a narrowing in a coronary artery. Coronary artery disease occurs when cholesterol plaque builds up (atherosclerosis) in the walls of the arteries to the heart. Angioplasty is successful in opening coronary arteries in 90% of patients. 40% of patients with successful coronary angioplasty will develop recurrent narrowing at the site of balloon inflation. (05 Mar 2000) |
| percutaneous transluminal angioplasty | An operation for enlarging a narrowed vascular lumen by inflating and withdrawing through the stenotic region a balloon on the tip of an angiographic catheter; may include positioning of an intravascular stent. (05 Mar 2000) |
| percutaneous transluminal coronary angioplasty | Percutaneous transluminal angioplasty of coronary artery or arteries. (05 Mar 2000) |
| coronary angioplasty | <cardiology, procedure> Percutaneous coronary angioplasty. This procedure involves the introduction of a thin flexible, hollow catheter into a artery in the groin. The catheter is advanced through the blood vessel to the heart. A special balloon tip on the catheter allows the physician to open a diseased (occluded) coronary artery by inflating the balloon and dilating the diseased vessel. (27 Sep 1997) |
| transluminal percutaneous coronary angioplasty | <cardiology, procedure> Dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply. (07 Mar 2000) |
| solid state laser | <radiobiology> A laser using a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing. The pumping mechanism is the radiation from a powerful light source, such as a flashlamp. The ruby, Nd-YAG, and Nd:glass lasers are solid-state lasers. (09 Oct 1997) |
| spectrometry, mass, matrix-assisted laser desorption-ionization | A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis. (12 Dec 1998) |
| dye laser | <radiobiology> A type of laser in which the active material (the material which emits the laser light) is a dye. These lasers are tunable when the dye has very large molecules (such as acridine red or esculin) and the laser action takes place between the first excited and ground electronic states, because each of these states contains a broad continuum band of vibrational-rotational levels. (09 Oct 1997) |
| yag laser surgery | <ophthalmology, procedure, surgery> The use of laser light to punch a hole in the iris to relieve intraocular pressure within the eye (for example glaucoma). This surgery is painless and requires no anaesthesia. (27 Sep 1997) |
| keratectomy, photorefractive, excimer laser | A type of refractive surgery of the cornea to correct myopia and astigmatism, using an excimer laser. An excimer laser is a laser containing a noble gas, such as helium or neon, which is based on a transition between an excited state in which a metastable bond exists between two gas atoms and a rapidly dissociating ground state. The extremely precise laser light reshapes the surface of the cornea without making an incision. This procedure can reduce much higher degrees of myopia than radial keratotomy (keratotomy, radial), although it generally takes longer for vision to clear. (12 Dec 1998) |
| laser | A medical instrument that produces a powerful beam of light and can produce intense heat when focused at close range. Lasers are often used in surgery to vaporize damaged cell tissue. (16 Dec 1997) |
