A simplified atrial catheterization technique for ventriculo-atrial shunt: puncture of the subclavian vein through the infraclavicular approach.

A simple technique to place an atrial catheter for ventriculo-atrial shunt has been developed. The subclavian vein is punctured percutaneously from the direction between the clavicle and the first rib by the same procedure used for central venous catheterization using the introducer designed for Fr. 7 catheter. The position of the tip of the catheter is determined by x-ray fluoroscopy. The technique was found to be simple, safe, and timesaving in two patients.
