Abstract Objective: To evaluate the value of color Doppler ultrasound in diagnosis of cesarean scar pregnancy. Methods: We analyzed retrospectively the data of 21 patients who were diagnosed as a cesarean scar pregnancy from December, 2008 to October, 2011 at affiliated hospital of Jining medical college and analyzed the ultrasonographic features of cesarean scar pregnancy. Results: Eighteen of 21 cases were correctly diagnosed of cesarean scar pregnancy by ultrasound. The accuracy of ultrasound diagnosis of cesarean scar pregnancy was 85.7%(18/21). One case misdiagnosed as cesarean scar pregnanly was trophoblastic disease confirmed by pathology. The misdiagnose rate was 4.8%(1/21). Two cases of cesarean scar pregnancy were missed and diagnosed as cervical pregnancy and incomplete abortion respectively by ultrasonography. The missed diagnose rate was 9.5%(2/21). The ultrasonography of cesarean scar pregnancy can be divided into three types: gestational sac type(10 cases), gestational sac-like structure type(5 cases) and mixed mass type(5 cases). Conclusion: Color Doppler ultrasound is important in the diagnosis of cesarean scar pregnancy, and can provide important reference information for early clinical diagnosis and treatment.
