Ventricular taps in the neonate under ultrasonic guidance. Technical note.

A method of ultrasonically guiding ventricular taps in children is described. The needle is introduced through a needle guide in the ultrasound field of a sectorscanner. The direction of the needle is accurately determined and the needle itself is clearly visualized on the television monitor during its introduction into the brain. The results of seven punctures are presented. All these punctures were successful at the first attempt, and no complications occurred.
