Can a transvaginal ultrasound detect intrauterine adhesions?

Vaginal ultrasound refers to transvaginal B-ultrasound. Whether it can detect intrauterine adhesions depends on the severity of the adhesions. The specific analysis is as follows:

1. Detectable

If the intrauterine adhesion is severe, with complete fusion preventing normal menstrual blood flow, a vaginal ultrasound may reveal a large amount of accumulated blood within the uterine cavity or a clearly interrupted endometrial line, indicating the presence of intrauterine adhesions.

2. Not detectable

If the intrauterine adhesion is mild and the endometrial line shows no significant changes, vaginal ultrasound usually cannot detect the adhesion. In such cases, diagnosis should be made via hysteroscopy based on cervical morphology and endometrial thickness. If adhesions are present, they can be separated using hysteroscopic surgery.

When intrauterine adhesions are suspected, definitive confirmation requires hysteroscopic examination.
