It is a rapidly progressing medical emergency requiring early recognition and intervention to prevent morbidity and mortality. Ruptured ectopic pregnancy is the number one cause of mortality in pregnancy-related deaths in the first trimester. Despite advancements in the diagnosis of ectopic pregnancy, it remains a serious source of maternal mortality, especially in developing countries due to limited healthcare. The incidence for ectopic pregnancy in females from 15 to 45 years old is 1 in 100 females in the general population, while those with preexisting tubal disease are more susceptible. Although several risk factors increase the likelihood of patients having ectopic pregnancy, nearly one-third of ectopic pregnancies have no identifiable risk factors (Table 162-1).
