  • Hydatidiform mole
  • Partial mole
  • Choriocarcinoma

Urinary tract infection, including

Urine microscopy and culture at first antenatal visit. Urinary tract infection (including asymptomatic bacteriuria) may be associated with premature delivery.

Pregnancy-induced hypertension (toxaemia)

  • Acute fatty liver

See under Hepatic failure

Venous thrombosis 

See under Thrombosis

  • Placental abruption
  • Septic abortion
  • Retained dead fetus
  • Amniotic fluid embolism

Amniotic fluid embolism

Hepatic failure

Factor VIII inhibitor 

A rare complication, developing within 3 months post-partum: APTT, PT; coagulation factor inhibitors. Consult pathologist.
