False Endometrial Thickening in Postmenopausal Patients Using Anticoagulants or Antiplatelets Agents

Objective There is no report that anticoagulant or antiplatelet use may lead to abnormal endometrial sonographic findings. This retrospective study reports our first results associated with endometrial sampling in asymptomatic postmenopausal women using anticoagulants or antiplatelet. Materials methods A total of 268 postmenopausal patients who applied to our gynecology outpatient clinic for any reasons except postmenopausal bleeding were included in the study. Patients were divided into three groups according to using drug status: first healty control group (HCG), second anticoagulants agents group (ACG), and third antiplatelet agents group (APG). The effects of anticoagulant and antiplatelet agents on endometrial thickness were compared with histopathological findings. Results The mean endometrial thickness was significantly greater in group ACG (5.2 mm) and APG (4.1 m) than in group HCG (3.3 mm). No significant differences were found in the mean endometrial thickness between groups HCG and APG. However, it is noteworthy that the average endomeric thickness in the ACG group is more than the other two groups and this is statistically significant (p 4 mm. endometrial sampling may be recommended in in asymptomatic postmenopausal women using anticoagulants or antiplatelet agents.
