We report on a woman with an Lp(a) lipoprotein level above the 99th centile of the population distribution of concentrations, who at the age of 43 had had deep vein thrombosis causing a pulmonary embolus and whose brother, who also had a very high level, had suffered a cerebral infarction at the age of 43. She had given birth to three children, all with very low birth weight, one of whom died when 3 months old. The placentas had been small and ischemic. The concurrence of a very high Lp(a) lipoprotein level, familial thromboembolic disease and recurrent placental ischemia with delivery of children with low birth weight suggests the possibility that a very high Lp(a) lipoprotein concentration may predispose to placental insufficiency, presumably arising from pathological changes in maternal uterine vessels in the placental bed. If confirmed, a very high Lp(a) lipoprotein level may be a factor to consider in women who have repeated pregnancies with placental insufficiency and who give birth to children with low birth weight.
