Efect and analysisof blood flow parameters of color Doppler ultrasound in patients with placenta implantationZhang Xiaoli. ， ，

【Abstract】 ObjectiveTo investigate the application value of color Doppler ultrasound in the evaluation of patients with placenta implantation，and to analyze its blood flow parameters.MethodsA prospective analysis was conducted，90 patientswith suspected placentaimplantationadmited tothe hospital from October2021 toOctober 2023 were selected.All patients underwent color Doppler ultrasonography to analyze the effect of color Doppler ultrasonography on thecondition assessment of placenta implantation patients.ResultsTheaccuracy，sensitivity and specificity of placenta implantation were 94% ， 89% and 96% in 18 of 88 suspected placenta implantation patients.Theresult of Kappa analysis showed that itwasO.829，which hadagood consistency.Thelevelsof blood flowindex（FI），（vascularizatioindex，VI），（vascularizationbloodflowindex，VF）andsystolicanddiastolicflowrate ration（S/D）in placenta implantation group were higher thanthose innon-placenta implantationgroup，with statistical significance （ P <0.05）.The levels ofFI，VI， VFI and S/D in patientswith severe placental implantation were higher than those in patientswith placental implantationand adhesion，the diference wasstatistically significant （ P <0.05）. Receiveroperator characteristic curve （ROC）was plotted，and the results showed that area under the curve （AUC）of color Doppler ultrasound in patients with placenta implantation was >0.70 in both single and combined evaluation， of which the combined evaluation value was thehighest.ConclusionColor Doppler ultrasound has high diagnostic efficacyinpatientswith placenta implantation，and can beused to evaluate theseverityof placenta implantation by blood flow parameters.

胎盤植入是臨床常見妊娠期疾病，正常情況下胎盤絨毛侵入子宮內(nèi)膜后改稱蛻膜，但若不植入子宮肌層以及蛻膜組織發(fā)育障礙時，絨毛組織就可能侵襲并植入子宮肌層，累及膀胱以及直腸組織，部分嚴(yán)重患者甚至出現(xiàn)產(chǎn)后大出血，對母嬰生命健康造成嚴(yán)重威脅[1]。（剩余6364字）
