Diagnostic value of transvaginal ultrasonography combined with contrast-enhanced ultrasound for cesarean scar pregnancy
Objective To analyze the application value of transvaginal ultrasonography(TVS)combined with contrast-enhanced ultrasound(CEUS)in the diagnosis of cesarean scar pregnancy(CSP).Methods Sixty patients with CSP confirmed by operation and pathology admitted to the First Hospital of Jiaxing from January 2022 to November 2023 were retrospectively analyzed.TVS and CEUS were examined before operation.The detection rate and type diagnosis of CSP were compared between TVS and CEUS alone and combined diagnosis.The receiver operating characteristic(ROC)curve was used to analyze the efficiency of TVS and CEUS in identifying gestational cesarean scar pregnancy(GCSP).Results Among the 60 patients with CSP,53 patients with GCSP and 7 patients with mass cesarean scar pregnancy(MCSP)were confirmed by surgery and pathology.The detection rate of CSP by TVS combined with CEUS(98.33％)was significantly higher than that by TVS or CEUS(P＜0.05),and the detection rate of CSP by CEUS was significantly higher than that by TVS(P＜0.05).The detection rate of GCSP by TVS combined with CEUS(100.00％)was significantly higher than that by TVS or CEUS(P＜0.05).The area under the curve(AUC)of TVS combined with CEUS for identifying GCSP was the largest,which was 0.857.The sensitivity was 100.00％,and the specificity was 71.40％.The detection rate of MCSP by TVS combined with CEUS was significantly higher than that by TVS(P＜0.05).Conclusion TVS combined with CEUS can effectively improve the clinical detection rate of CSP,which is conducive to the diagnosis of CSP classification,and has important application value.
