- Implantation of the fetus at any site other than the uterus
- Most commonly the tubes – 90%
- Occur 1 in every 150 pregnancies
- Most important predisposing condition is PID with chronic salpingitis
- Clinical features include severe abdominal pain around 6 weeks after the last period
- Patient may be in a shock like state if the tube has ruptured
- In a tubal pregnancy, the placenta is poorly attached to the wall of the tube
- Intratubal haemorrhage may then occur without tube rupture due to partial placental separation
- The most common cause of hmatosalpinx is a tubal pregnancy
- More commonly the placenta invades through the tubal wall and causes intraperitoneal haemorrhage
- Less commonly the tubal pregnancy may undergo spontaneous regression and reabsortion
- Even less commonly the tubal pregnancy is extruded through the fimbriated end into the abdominal cavity (tubal abortion)
