Seldinger technique
Seldinger technique (pronunciation: sel-ding-er tek-neek) is a medical procedure used to gain safe access to blood vessels and other hollow organs. It is named after the Swedish radiologist, Dr. Sven Ivar Seldinger (1921-1998), who introduced the procedure in 1953.
Etymology
The term "Seldinger technique" is derived from the name of its inventor, Dr. Seldinger. The word "technique" comes from the Greek "τέχνη" (techne), meaning "art, skill, craft in work; method, system, an art, a system or method of making or doing."
Procedure
The Seldinger technique involves the introduction of a needle into the desired vessel or cavity, followed by the insertion of a wire through the needle. The needle is then removed, and a sheath or catheter is passed over the wire into the desired location. The wire is then removed, leaving the sheath or catheter in place.
