Clinical effect of intrauterine perfusion of autologous PBMCs combined with low molecular weight heparin in the treatment of postoperative intrauterine adhesions / 中国医师杂志

ABSTRACT

Objective:To investigate the assisted pregnancy clinical effect of autologous peripheral blood mononuclear cells (PBMCs) combined with low molecular weight heparin (LMWH) on patients with intrauterine adhesion separation.Methods:Nine patients with intrauterine adhesion separation were treated with intrauterine perfusion of PBMCs 48 hours before transplantation. The low molecular weight heparin 3 200 IU injected daily subcutaneously were carried out on the day of transplantation. Measurement of endometrial thickness and observation of pregnant outcome were perfomed.Results:After 9 patients were injected into the uterine cavity with autologous PBMCs. It was found that, compared to the previous, the thickness of the endometrium was increased, and the morphology of the endometrium was improved in 6 cases. After transplantation, 7 cases of the patients were clinically pregnant, 1 of the patients was biochemically pregnant, and 1 of the patients was not pregnant; among the 7 clinical pregnancy cases, 1 case was intrauterine compound pregnancy (operation on the affected side of fallopian tube pregnancy had been performed), another 2 cases had embryo termination at the 7-8th week of gestation by B-scan ultrasonography analysis. However, 3 cases of clinical pregnancy in 4 patients with repeated implantation failure. At present, 2 cases were in live labor, and the other three cases were in normal continuous pregnancy.Conclusions:Intrauterine perfusion of human PBMCs combined with low molecular weight heparin is beneficial to the improvement of endometrial receptivity and the pregnancy outcome of some patients after the separation of intrauterine adhesions.
