[Clinical Value of Ultrasonography in Predicting Massive Hemorrhage during Cesarean Scar Pregnancy].

OBJECTIVE: To investigate the clinical value of ultrasonography in predicting massive haemorrhage during Cesarean scar pregnancy. METHODS: The clinical and ultrasonograhic data of 119 Cesarean scar pregnancy patients were retrospective analyzed. According to the amount of bleeding, these patients were divided into two groups:massive hemorrhage group and non-massive hemorrhage group. The potential risk factors of massive hemorrhage were analyzed with Logistic regression analysis. RESULTS: The size and type of lesions, flow grade, and residual muscular thickness were screened as the risk factors of massive haemorrhage by Logistic regression model. When P=0.3 was applied as the cutoff value,the diagnostic accuracy was 90.75%;meanwhile,the sensitivity,specificity,positive predictive value, and negative predictive value were 88.23%, 91.76%, 81.08%, and 95.12%,respectively. CONCLUSION: Ultrasonography can accurately predict the risk of massive hemorrhage during the Cesarean scar pregnancy.
