What is the Seldinger method for arterial access?

The 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 after Dr. Sven Ivar Seldinger (1921–1998), a Swedish radiologist who introduced the procedure in 1953.

What are the steps of the Seldinger technique?

Technique

desired vessel or cavity is punctured using a trocar (hollow needle)
soft curved tip guide wire is then inserted through the trocar and advanced into the lumen.
guidewire is held secured in place whilst the introducer trocar is removed.

When employing the Seldinger method of catheterization What is the most common artery that is used?

It is also commonly a technique used in placement of an arterial line (a-line) in the radial or femoral artery when continuous blood pressure monitoring is needed.

Is Seldinger technique percutaneous?

The Seldinger technique is the most commonly used method of gaining central venous access. It was initially described in 1953 by Seldinger as a vascular access method for percutaneous arteriography.

What is a modified Seldinger technique?

A modified Seldinger technique entails advancing a fine catheter over a needle into the vessel and withdrawing the needle. The fine catheter rather than the needle can then be used as a conduit for inserting the guide wire.

What is Judkins technique?

Catheters used for performing coronary angiography via the femoral artery were developed by Melvin Judkins, MD; thus, the method often is referred to as the Judkins technique. This widely used method requires separate preformed catheters for the right and left coronary arteries (see the images below).

What type of catheter is placed using the modified Seldinger technique?

The modified Seldinger technique allows for placement of large-bore catheters in jugu- lar veins, the pleural space, pulmonary arteries, and even hollow organs. It is also often used to place dialysis catheters.

Which arm is used for cardiac catheterization?

Transradial cardiac catheterization can be effectively and safely performed using either right or left radial arteries for vascular access.

Why is a pigtail catheter used in left heart catheterization?

A curved catheter with a pigtail tip is described, which provides for stable yet rapid delivery of contrast medium to either ventricle, the aorta and the pulmonary arteries.

What is IJ cutdown?

38.94. MeSH. D016748. Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used to get vascular access in trauma and hypovolemic shock patients when peripheral cannulation is difficult or impossible.

What is the Seldinger technique used for?

Seldinger technique(thin-wall needle technique) is commonly used procedure to obtain safe access to central vein. The desired vessel is punctured with a sharp hollow needle, syringe is detached and guidewire is advanced through the lumen of the needle, and then the needle is withdrawn.
