The association between menstrual cycle pattern and hysteroscopic march classification with endometrial thickness among infertile women with Asherman syndrome

Abstract

Women with Asherman syndrome (AS) have intrauterine adhesions obliterating the uterine cavity. Hysteroscopic March classification describes the adhesions which graded in terms of severity. This study has been designed to assess the prevalence and association between of clinical presentations, potential causes, and hysteroscopic March classification of AS among infertile women with endometrial thickness.A retrospective descriptive study was carried out that included 41 women diagnosed with AS. All of the patients underwent evaluation and detailed history. All cases classified according to March classification of AS were recorded. Patients were divided into 2 groups based on measurement of endometrial thickness. Group A consisted of 26 patients with endometrial thickness ≤5 mm, and group B included 15 patients with endometrial thickness >5 mm.The prevalence of AS was 4.6%. Hypomenorrhea was identified in about 46.3%, and secondary infertility 70.7%. History of induced abortion, curettage, and postpartum hemorrhage were reported among 56.1%, 51.2%, and 31.7%, respectively. AS cases were classified as minimal in 34.1%, moderate 41.5%, and severe among 24.4% as per March classification. Amenorrhea was reported by 23.1% of women in group A, compared to 0% in group B (P = .002). Ten of 26 patients (38.5%) from group A had a severe form of March classification, compared with 0 of 15 patients (0%) in group B. This was statistically significant (P < .001).The thin endometrium associated with amenorrhea and severe form of March classification among patients with AS.
