Seldinger technique

Seldinger technique is a procedure for inserting vascular catheters. A wire (special wire with a "J" end to protect the vessel wall) is inserted through the puncture needle, the needle is removed, and then catheters suitable for the examination are inserted using a wire. For easier penetration into the vessel, the entrance can first be adjusted using dilators. The technique is used in angiography, chest drainage or in the insertion of a central venous catheter.
