[Premature detachment of ova diagnosed by echography. Apropos of 42 cases]

The authors noted, while carrying out ultrasound examinations, that there was many cases of abruption of oocytes at the beginning of pregnancy. This study was of 42 cases in 3 maternity units of Paris and its suburbs. It shows up how often, in pregnancies complicated bleeding in the first trimester, ultrasound can demonstrate such abruption. Ultrasound pictures can demonstrate the principal characteristics and the outcome of these abruptions, as well as their effect on the continuation of the pregnancy. In this way it establishes a correlation between the anatomy and the pathology and brings to the fore various hypothesis as to the aetiology of these pathological conditions.
