Abstract:
13 bypasses and 8 patches were examined by ultrasound in vitro with a 3.5 MHz and a 10 MHz probe. Whereas only 6 bypasses were assessable by sonography, all patches could be demonstrated in vitro. In these cases, sonography could be accomplished with either of the two frequencies used. The 10 MHz probe was superior for imaging structural details. Immediate postoperative sonography of such grafts, which cannot be demonstrated accurately in vitro, is not reliable.
