Clinical value of the human chorionic gonadotropin level combined with the transvaginal ultrasound for diagnosing their ec-topic pregnancy and the influencing factors
Objective: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 retrospective-ly.The serum β-hCG level and the transvaginal ultrasound results of the patients were analyzed.The surgical and path-ological diagnosis of the patients was as the gold standard to analyze the value of the serum β-hCG level,the transvagi-nal ultrasound results,and the combined detection of the β-hCG level and the transvaginal ultrasound results for diag-nosing the ectopic pregnancy of the patients.Multivariate logistic regression analysis was used to analyze the influen-cing factors of diagnosing the ectopic pregnancy.Results:The positive values of theβ-hCG level,the transvaginal ultra-sound 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 a-nalysis 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 high-er 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.
