Abstract To analyze the level of serum human chorionic gonadotropin(β-hCG) combined with transvaginal ultrasound of patients for diagnosing their ectopic pregnancy. Methods: The clinical data of 90 patients with suspected ectopic pregnancy diagnosed and treated in hospital from February 2020 to February 2023 were collected retrospectively. The serum β-hCG level and the transvaginal ultrasound results of the patients were analyzed. The surgical and pathological diagnosis of the patients was as the gold standard to analyze the value of the serum β-hCG level, the transvaginal ultrasound results, and the combined detection of the β-hCG level and the transvaginal ultrasound results for diagnosing the ectopic pregnancy of the patients. Multivariate logistic regression analysis was used to analyze the influencing factors of diagnosing the ectopic pregnancy. Results: The positive values of theβ-hCG level, the transvaginal ultrasound results, and the combined detection of the β-hCG level and the transvaginal ultrasound results of the patients for diagnosing their ectopic pregnancy were 71.1%, 71.4% and 84.8%, respectively, and the negative predictive values of which were 75.6%, 72.9% and 90.9%, respectively. Both the β-hCG level and the transvaginal ultrasound results of the patients had certain diagnostic value for their ectopic pregnancy, and the area under the curve of the β-hCG level and the transvaginal ultrasound results of the patients for diagnosing their ectopic pregnancy was 0.74 and 0.732. The area under the curve of the combined detection of the β-hCG level and the transvaginal ultrasound results of the patients for diagnosing their ectopic pregnancy was 0.890, which was the highest(P<0.05). Multivariate logistic regression analysis showed that the negative results of theβ-hCG level and the transvaginal ultrasound of the patients were the risk factors affecting the diagnosis of their ectopic pregnancy. Conclusion: The combined β-hCG level and the transvaginal ultrasound results of the patients for diagnosing their ectopic pregnancy can improve the diagnostic efficacy, with higher sensitivity and specificity. The negative results of theβ-hCG level and the transvaginal ultrasound of the patients are the risk factors affecting the diagnosis of their ectopic pregnancy.
