[Changes of coagulation function in patients with adenomyosis and its clinical significance].

To measure the coagulation function of patients with adenomyosis so as to explore its relationship with increased menstrual amount and its clinical significance. From January 2014 to May 2019, clinical data of patients with hysterectomy in which 111 pathologically diagnosed adenomyosis (case group) and 115 with uterine myoma (control group) in Peking University First Hospital were retrospectively analyzed. The changes in coagulation function of the two groups were compared, and the correlation between coagulation and uterine volume in the adenomyosis group was analyzed. (1) The activated partial thromboplastin time (APTT) was longer in the adenomyosis group than that in the uterine myoma group [(30.4±3.1), (29.6±2.5) s, respectively; <0.05], while the thrombin time (TT) was shorter than that in the control group [(14.2±1.2), (14.6±1.0) s, respectively; <0.05]. (2) According to the results of the Pearson correlation test, there was a positive correlation between prothrombin time (PT; =0.135, =0.042) and fibrinogen (FIB-C; =0.139, =0.036). (3) Platelet counts were higher in the anemia group of adenomyosis than that in the non-anemia group [(323±79)×10/L, (274±56)×10/L, respectively; <0.05]. (4) FIB-C in non-anemia group of adenomyosis was lower than non-anemia group of uterine myoma [(2.8±0.5), (3.0±0.6) g/L, respectively; <0.05], the anemia group of adenomyosis shortened TT compared with the anemia group of uterine myoma [(14.4±1.2), (15.2±0.9) s, respectively; <0.05]. Patients with adenomyosis have abnormal coagulation function, which may be related to the increase amount of menstruation, and anemia may also be involved in coagulation disorders.
