title: [Chronic premature detachment of placenta].
abstract: OBJECTIVE
  to evidence the existence of chronic premature separation of the placenta.
  
  
  METHODS
  retrospective. SITE: Hospital of the Jundiaí School of Medicine.
  
  
  METHODS
  four patients of the authors.
  
  
  METHODS
  without statistical treatment because this is not a comparative study.
  
  
  RESULTS
  chronic premature separation of the placenta, a classical asymptomatic or monosymptomatic disorder, can be detected by ultrasound and/or cardiotocography. Four cases seen among the authors' patients are presented, who were diagnosed by insidious evolution, discrete blood loss, and uterine excitability. Three of the patients were hypertensive. Diagnosis was established by amniocentesis, single or serial ultrasound, and cardiotocography. Newborns were premature, but the four of them survived.
  
  
  CONCLUSIONS
  the authors conclude that the obstetric treatment depends on gestational age, fetal conditions, size of the clot, and intensity of blood losses. A conservative approach may be appropriate depending on fetal-maternal conditions. However, further studies are needed to devise more adequate approaches.
