Seldinger techniqueThe Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named afterSven Ivar Seldinger (1921–1998), a Swedishradiologist who introduced the procedure in 1953.
AngioplastyAngioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty, is a minimally invasiveendovascularprocedure used to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowedvessel and then inflated to a fixed size.
Sven Ivar SeldingerSven Ivar Seldinger (19 April 1921 – 21 February 1998), was a radiologist from Mora Municipality, Sweden. In 1953, he introduced the Seldinger technique to obtain safe access to blood vessels and other hollow organs. BiographySven Ivar Seldinger was born on 19 April 1921 in Dalarna, Sweden. He was born to a family who had long run the local Mora Mechanical Workshop. He first began his medical training in 1940 at the Karolinska Institute.
CatheterIn medicine, a catheter ( ) is a thin tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. Catheters are manufactured for specific applications, such as cardiovascular, urological, gastrointestinal, neurovascular and ophthalmic procedures. The process of inserting a catheter is called catheterization.
Blood vesselBlood vessels are the tubular structures of a circulatory system transporting blood in animal bodies. Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body, and also transport waste products and carbon dioxide away from the tissues. Some tissues – such as cartilage, epithelium, and the lens and cornea of the eye – are not supplied with blood vessels, so are termed avascular.
StentIn medicine, a stent is a tube usually constructed of a metallic alloy or a polymer. It is inserted into the lumen (hollow space) of an anatomic vessel or duct to keep the passageway open. 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.
TrocarA trocar (or trochar) is a medical or veterinary device traditionally used in draining or venting procedures, now also (informally termed a port) prominent in minimally invasive surgery. Trocars are typically made up of an obturator (which may be metal or plastic, and with a pointed or tapered tip), within a cannula (essentially a rigid tube), and often with a seal.
SurgerySurgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissues, neoplasms and foreign bodies.
Lumen (anatomy)In biology, a lumen (pl.: lumina) is the inside space of a tubular structure, such as an artery or intestine. It comes from Latin lumen'an opening'.
ScalpelA scalpel or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomicaldissection, podiatry and various handicrafts. A lancet is a double-edged scalpel. Scalpel blades are usually made of hardened and tempered steel, stainless steel, or high carbon steel; in addition, titanium, ceramic, diamond and even obsidian knives are not uncommon.
Percutaneous coronary interventionPercutaneous 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. The procedure is used to place and deploy coronary stents, a permanent wire-meshed tube, to open narrowed coronary arteries.
Cardiac catheterizationCardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").*As an Amazon Associate I earn from qualifying purchases.
