Abstract: Four cases of medical malpractice induced by prenatal ultrasonographic examination and sentenced by court were selected， and then the medical treatment faults， corresponding damages and the principles for judging the relationship between malpractice and medical damage in such cases were discussed. It is proposed that in such cases， attention should be paid to the standardization of antenatal examination， and the skill differences between medical organizations ought to be properly evaluated. Besides， the timeliness factor also needs to be considered. Generally， the medical damage caused in such case is the birth of a defective baby. The causality analysis between medical malpractice and medical damage in this kind of cases is different from that in ordinary medical malpractices， and should be handled with particularly caution.

Key words: prenatal ultrasonographic examination, medical malpractice, forensic medical examination
