Recent proposed federal legislation banning certain abortion procedure
s, particularly intact dilatation and extraction, would modify the US
Criminal Code such that physicians performing these procedures would b
e liable for monetary and statutory damages. Clarification of medical
procedures is important because some of the procedures used to induce
abortion prior to viability are identical or similar to postviability
procedures. This article reviews the scientific and medical informatio
n on late-term abortion and late-term abortion techniques and includes
data on the prevalence of late-term abortion, abortion-related mortal
ity and morbidity rates, and legal issues regarding fetal viability an
d the balance of maternal and fetal interests. According to enacted Am
erican Medical Association (AMA) policy, the use of appropriate medica
l terminology is critical in defining late-term abortion procedures, p
articularly intact dilatation and extraction, which is a variant of bu
t distinct from dilatation and evacuation. The AMA recommends that the
intact dilatation and extraction procedure not be used unless alterna
tive procedures pose materially greater risk to the woman and that abo
rtions not be performed in the third trimester except in cases of seri
ous fetal anomalies incompatible with life. Major medical societies ar
e urged to collaborate on clinical guidelines on late-term abortion te
chniques and circumstances that conform to standards of good medical p
ractice. More research on the advantages and disadvantages of specific
abortion procedures would help physicians make informed choices about
specific abortion procedures. Expanded ongoing data surveillance syst
ems estimating the prevalence of abortion are also needed.
