What does the Seldinger technique provide access to?

The Seldinger technique is primarily used to obtain access to blood vessels for various medical procedures. This method involves the insertion of a thin guide wire through a needle into a vessel, allowing for subsequent placement of larger catheters or devices over the wire. It is especially valuable in minimally invasive procedures such as catheter placements, central venous access, and interventional radiology.

The precision and effectiveness of the Seldinger technique in achieving vascular access have made it a standard in many medical disciplines, particularly where blood vessel access is necessary for diagnostic or therapeutic interventions. The other options—accessing bone, nerves, or joints—are addressed through different techniques that do not utilize the same methodology as the Seldinger approach. Therefore, the most accurate representation of what the Seldinger technique provides is vessel access for percutaneous procedures.
