title: Fetomaternal blood group incompatibility studies in placental intervillous thrombosis.
abstract: Samples of maternal and fetal blood from 32 cases of placental intervillous thrombosis have been analysed for blood group incompatibility and compared to a control group of 21 cases. No overall link has been demonstrated between intervillous thrombosis and ABO incompatibility. Red cell antibody reactions of all types probably account for only a small proportion of thrombi and it is suggested that the principle mechanism may be a thromboplastin release from the damaged vasculo-syncytial membrane, causing a coagulation of the mixed maternal and fetal cells.
