ObjectiveTo analyze the accuracy of ultrasound in the diagnosis of ectopic pregnancy and its influencing factors.

MethodsThe clinical data of 156 patients with ectopic pregnancy diagnosed by ultrasound were retrospectively analyzed.The results of surgical pathology were followed up to verify the consistency between the ultrasound diagnosis and pathological report diagnosis, and the factors influencing the accuracy of ultrasound diagnosis were analyzed.

ResultsAmong 156 cases, 125 patients were confirmed by pathology, and the diagnostic accuracy of which was 80.13%.The pregnancy sac in 144 cases were clearly detected using ultrasound, and the unknown location of pregnancy sac in 12 cases were not detected by initial ultrasound.The results of multivariate logistic regression analysis showed that the pelvic inflammation, serum human chorionic gonadotropin(HCG) and menopause time >6 weeks were the independent influencing factors of ultrasonic diagnosis accuracy of ectopic pregnancy(P < 0.01).

ConclusionsDuring the clinical diagnosis and treatment of ectopic pregnancy, the early ectopic pregnancy and pelvic inflammatory disease should be paid attention to.For undiagnosed patients, the accuracy of ultrasonic diagnosis of ectopic pregnancy can be improved as far as possible by combining serum human chorionic gonadotropin level, clinical symptoms and follow-up of patients.
