Can intrauterine adhesions be seen through B-ultrasound?

Uterine adhesions can usually be initially detected through B-ultrasound examination, but the diagnosis needs to be combined with hysteroscopy. Intrauterine adhesions may be related to factors such as induced abortion, uterine infection, endometrial damage, etc., and are mainly manifested by symptoms such as decreased menstrual flow, amenorrhea, or infertility.

B-ultrasound examination has certain limitations in the diagnosis of intrauterine adhesions. Ordinary two-dimensional B-ultrasound may show indirect signs such as interruption of the endometrial line, abnormal uterine cavity shape, or fluid accumulation, but it is easy to miss the diagnosis of mild adhesions. Three-dimensional ultrasound can increase the detection rate and display the location and range of adhesions more clearly, and is especially sensitive to central adhesions. Transvaginal ultrasound has higher resolution than abdominal ultrasound and can observe changes in endometrial thickness and blood flow signal abnormalities. However, B-ultrasound cannot accurately determine the nature and density of adhesion tissue, and some membranous adhesions may not have typical imaging manifestations.

For cases where intrauterine adhesions are highly suspected, further examination is still required even if no clear abnormalities are found on B-ultrasound. Hysteroscopy is the gold standard for diagnosis. It can directly observe the shape of the uterine cavity, the extent of adhesions and the status of the endometrium, and can also perform adhesion separation and treatment. Hysterosalpingography can assist in assessing fallopian tube patency, but has low specificity in diagnosing adhesions. Magnetic resonance imaging has diagnostic value in complex adhesions combined with deep muscle layer injuries.

It is recommended to seek medical advice as soon as possible when abnormal menstruation or infertility symptoms occur. The doctor will choose an appropriate diagnostic plan based on the medical history and preliminary examination results. After surgery, patients need to follow the doctor's advice to use estrogen to promote endometrial repair, conduct regular reviews to prevent re-adhesion, and place an intrauterine device or balloon to isolate the wound if necessary. It is necessary to pay attention to the cleaning of the perineum every day to avoid infection factors. Sexual life and bathing in the bath are prohibited within 3 months after the operation.
