Fatal pulmonary embolism during legal induced abortion in the United States from 1972 to 1985.
To determine the risk factors for abortion-related deaths caused by pulmonary embolism, we investigated all deaths from legal abortions in the United States from 1972 through 1985. Of 213 deaths, 45 (21%) were due to air, blood clot, or amniotic fluid embolism. The risk of embolism death was higher among minority women and older women (34 to 44 years). Our analysis revealed that curettage at less than or equal to 21 weeks and abortions at less than or equal to 12 weeks, regardless of method, were both associated with the least risk of embolism death. In comparing 1972 to 1978 and 1979 to 1985, we found that the embolism mortality rate decreased 79%. During 1979 to 1985, the number of abortions performed by noncurettage methods decreased 58%, possibly as a result of earlier abortion morbidity studies, which showed that these methods carried a greater risk of complications. Although a decrease in mortality rates may be partially attributable to the declining use of these methods, our analysis suggests that changes in methods over time have not been universally applied to all racial groups.
