Clinical Value of Ultrasonography in Predicting Massive Hemorrhage during Cesarean Scar Pregnancy / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical value of ultrasonography in predicting massive haemorrhage during Cesarean scar pregnancy.</p><p><b>METHODS</b>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 groupsmassive hemorrhage group and non-massive hemorrhage group. The potential risk factors of massive hemorrhage were analyzed with Logistic regression analysis.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Ultrasonography can accurately predict the risk of massive hemorrhage during the Cesarean scar pregnancy.</p>
