Maternal-fetal lead poisoning from a 15-year-old bullet

Abstract

Blood lead was mildly elevated (31 microg/dl, where 25 microg/dl is the upper limit of the normal range) in a woman with lumbar bullet fragments who was evaluated for anemia in the 23rd week of pregnancy. She required Cesarean section at term for pre-eclampsia and fetal distress. The infant had multiple congenital abnormalities. Postpartum maternal blood lead level was 75-85 microg/dl. The infant's blood lead level was also elevated. Chelation lowered the infant's blood lead level, but not the mother's. Surgical debulking of the lumbar lead deposits was followed by a fall in blood lead level from 65 to 52 microg/dl. This case demonstrates a remarkable gestational rise in maternal blood lead level. The infant's congenital abnormalities could be causally related to lead.
