Spontaneous heterotopic pregnancy with live infant: report of two cases.

Heterotopic pregnancy is a potentially fatal condition that rarely occurs in natural conception cycles. We report two cases diagnosed within one month in a 20 year old gravida 3, para 0+2 without any known risk factor and a 38 year old gravida 12, para 6+5 with risk factors. The ectopic pregnancies were diagnosed after rupturing at 10 and 17 weeks respectively and resected via laparotomies. The courses of the intrauterine pregnancies were uneventful and both clients delivered vaginally at term. Heterotopic pregnancy is an important differential diagnosis to consider in clients with intrauterine pregnancies presenting with acute abdominal pain and haemoperitoneum.
