● Implantation of the embryo outside of the uterine cavity including within the tubes (90%), abdomen and the cornua of the uterus
● Occurs in 1/150 pregnancies
● Tubal pregnancies are the most common cause of hematosalpinx due to rupture, which is a medical emergency, and diagnosed with ultrasound, serum hCG and laparoscopy
● Bleeding is sometimes due to placental separation without rupture
● 50% are associated with pelvic inflammatory disease or peritubal adhesions (due to appendicitis, endometriosis, surgery and leiomyomas)
● Though not extensively studied, reports indicate a high prevalence of placenta accreta and percreta, to which tubal rupture is attributed
● Placentas from abdominal pregnancies have been described as highly vascular with markedly diminished / absent decidua
