Ultrasound visualization of the 5-F catheter.
A simple in vitro experiment showed that the 5-F angiographic catheter can be visualized on sonograms. Subsequent in vivo imaging showed that small catheters can be seen sonographically in many locations. Ultrasound is proposed as an effective presurgical procedure in order to determine whether a catheter fragment remains near an arterial puncture or has embolized distally.
