OBJECTIVE We reevaluated Cesarean scar pregnancies (CSP) diagnosed according to the modified Delphi method. Our aim was to discuss our ultrasonography (US) and Doppler US findings and treatment experiences. METHODS Ultrasound images of pregnant women diagnosed with CSP were retrospectively reanalyzed using the modified Delphi method. Doppler US images were graded according to vascularity density. The treatment process, medical/ surgical applications, serum βhCG levels and hemogram results of the pregnant diagnosed with CSP were analyzed from the hospital data system. RESULTS Ten cases were classified as Type1 CSP (35.7%), 12 cases as Type2 CSP (42.8%) and 6 cases as Type 3 CSP (21.4%). Residual myometrial thickness (RMT) was between 1.6-4.2 mm in Type 1 CSP cases and 1.0-2.7 mm in Type 2 CSP cases. In Type 3 CSP cases, the gestational sac (GS) was protruding from the serosa and RMT could not be measured. Adjacent myometrial thickness size was measured between 6.1-12.6 mm in all CSP cases. In Doppler images, it was observed that the vascularity around the GS was variable in Type 1 and Type 2 CSP cases. All Type 3 CSP cases had severe vascularity around the GS. Severe Doppler vascularity seen in Type 3 CSP cases wasn’t observed in any Type1 CSP case. CONCLUSION The Modified Delphi methodology is one that facilitates the diagnosis of CSP. The severity of vascularity on Doppler US images may be useful in typing CSP and early diagnosis.
