title: Hysteroscopic findings in 344 women with recurrent spontaneous abortion.
abstract: OBJECTIVE
  To evaluate the prevalence of different anatomic factors in women with recurrent spontaneous abortion (RSA).
  
  
  METHODS
  Retrospective analysis over 9 years (Canadian Task Force classification II-2).
  
  
  METHODS
  University hospital-affiliated endoscopic unit.
  
  
  METHODS
  Three hundred forty-four consecutive patients with RSA and 922 controls referred for abnormal uterine bleeding.
  
  
  METHODS
  Diagnostic hysteroscopy.
  
  
  RESULTS
  Major and minor uterine mullerian abnormalities (septate, unicornuate uteri) were found significantly more often in women with RSA than in controls (32% vs 6%, p <0.001). The frequency of acquired uterine anomalies (submucous myomas, polyps) was significantly higher in controls (32% vs 9%, p <0.001). No significant differences were observed between groups in frequency of adhesions (4% vs 2%).
  
  
  CONCLUSIONS
  Major mullerian uterine abnormalities are associated with RSA, and minor uterine anomalies may be correlated with an increased risk of recurrent miscarriage.
