Value and Application of Intracavitary Probe Transabdominal Ultrasound in Diagnosis of Cesarean Scar Pregnancy

Objective To evaluate the clinical effectiveness of ITAS(Intracavitary Probe Transabdominal Ultrasound) in diagnosis of CSP(Cesarean Scar Pregnancy).Methods Conventional TAS(Transabdominal Ultrasound),conventional TVS(Transvaginal Ultrasound) and ITAS were performed respectively in 46 patients who were confirmed as sufferers from cesarean scar pregnancy in our hospital,based on which comparative analysis was made.Results Comparisons of the definite diagnosis rate were drawn among TAS,TVS and ITAS,which was of great statistical significance(P0.05).Ultrasound images obtained through conventional TVS and ITAS were sharper than that through conventional TAS in displaying the thickness of the muscular layer in the uterine scar.As for exploration of blood flow RI(Resistance Index) in the trophoblast of the scar,ITAS was more sensitive than TAS and TVS.Conclusion As a supplemental diagnostic technique to conventional TAS and conventional TVS,ITAS is of great value in guiding the clinical diagnosis and treatment of CSP.
