Office hysteroscopic findings in patients with two, three, and four or more, consecutive miscarriages.

OBJECTIVES

To assess hysteroscopic findings in patients with two, three, and four or more, consecutive miscarriages, and to compare the prevalence of uterine abnormalities between women with different numbers of such miscarriages.

METHODS

Two hundred and sixty-five women with two or more consecutive miscarriages were enrolled in the study. Patients were divided into three groups according to the number of their miscarriages: Group 1 (two miscarriages, n = 151), Group 2 (three miscariages, n = 69), and Group 3 (four or more miscarriages, n = 45). All participants underwent a diagnostic hysteroscopy. Congenital (arcuate uterus, septate uterus, unicornuate uterus) and acquired uterine abnormalities (intrauterine adhesions, polyp and submucous myoma) were recorded. The hysteroscopic results were compared between the groups.

RESULTS

No anomalies were detected in 152 patients (57%), whereas 43 (16%) had a septate uterus, 30 (11%) an arcuate uterus, three (1%) a unicornuate uterus, 18 (7%) intrauterine adhesions, 17 (6 %) endometrial polyps, and two (1%) a submucous myoma. No significant differences were found between the groups with regard to either congenital or acquired uterine abnormalities.

CONCLUSIONS

Patients with two, three, and four or more consecutive miscarriages have a similar prevalence of uterine anatomical abnormalities. Diagnostic hysteroscopy should be carried out after two such miscarriages.
