Seldingerinläggningar

Seldingerinläggningar refers to the placement of a Seldinger catheter, a medical device used to access blood vessels and other hollow organs. This technique, named after its inventor Sven-Ivar Seldinger, is a cornerstone of interventional radiology and minimally invasive surgery. The procedure begins with a small skin incision, through which a needle is inserted into the target vessel. A guidewire is then advanced through the needle, and once positioned correctly, the needle is removed, leaving the guidewire in place. A sheath, also known as a dilator or introducer, is then threaded over the guidewire and into the vessel. This sheath creates a stable channel, allowing for the removal of the guidewire and subsequent insertion of various medical instruments, such as catheters, stents, or drainage tubes, into the body.

The Seldinger technique is versatile and can be used to access a wide range of anatomical locations, including arteries and veins in the limbs, neck, and abdomen, as well as the urinary tract and biliary system. Its primary advantage lies in its minimally invasive nature, reducing the need for open surgery and its associated risks and recovery times. Common applications include angiography for diagnostic imaging, angioplasty and stenting to open blocked vessels, placing central venous catheters for medication delivery or monitoring, and performing biopsies. The success of the Seldinger technique relies on precise anatomical knowledge and careful manipulation of the guidewire and associated instruments. While generally safe, potential complications can include bleeding, hematoma formation, infection, or damage to the blood vessel.
