“…This is exemplified by the confusion surrounding the relationship between pre-eclamptic toxaemia and infarction of the placenta, about which three conflicting schools of thought have arisen (Table I). The first maintains that 'acute' infarcts of the placenta are pathognomonic of toxaemia and are, furthermore, the cause of the toxaemic symptoms [3,4,5,32,53,63], whilst the second has thought that infaredon is the result rather than the cause of the toxaemic process [1,6,14,16,18,20,25,26,27,30,34,35,36,37,40,43,44,45,47,49,51,52,55,56,57,59,60,61,64,65] and that, although die incidence of placental in farction is significantly increased in toxaemia, the presence of infarcts is not an invariable feature. By contrast, a third group of workers have been unable to confirm that the incidence of placental infarction in cases of pre-eclamptic toxaemia is notably different from that found in uncomplicated pregnancies [15,17,28,39,41,46,…”
