Objective:

To study the application value of transvaginal three-dimensional ultrasound (3D-TVS) in the postoperative follow-up of intrauterine adhesions.

Methods:

A total of 132 patients with moderate or severe intrauterine adhesion were diagnosed by hysteroscopy and 3D-TVS and treated by transcervical resection of adhesion (TCRA). All patients received the examination of 3D-TVS and the results were co

mpared with those of secondary hysteroscopy three months later. Pre- and post operative endometrial volume and blood flow parameters of 3D-TVS were observed and compared.

Results:

The endometrial volume

flow index (FI) and vascularization flow index (VFI) after TCRA were increased compared with those before TCRA (

P

0.05). Although the vascularization index (VI) was slightly increased after TCRA

the difference was not statistically significant (

P

0.05).The sensitivity

specificity and accuracy of postoperative 3D-TVS for the diagnosis of intrauterine adhesions were 85.0% (51/60)

83.3% (60/72)

84.1% (111/132)

respectively.

Conclusion:

In accordance with hysteroscopy

3D-TVS is useful to evaluate the endometrial volume and blood flow parameters with convenience and reliable quality.
