The diagnostic value of transvaginal color Doppler in the detection of intrauterine remnants

Objective TO explore the clinical values of transvaginal color Doppler (TV-CDFI)and tansabdominal color Doppler (TA-CDFI) in detection of intrauterine remnants. Methods 98 patients with intrauterine remnants underwent TV-CDFI and TA-CDFI. The findings were then compared with pathological examination after curettage. Results All the patients were pathologically confirmed as intrauterine remnants after suction curettage. The coincidence rate between TV-CDFI and pathological diagnosis was 97.9%, and that between TA-CDFI and pathological diagnosis was 74.5%. There were 2 patients misdiagnosed by TV-CDFI and 25 by TA-CDFI. The misdiagnosis rate in detecting intrauterine fetal residue smaller than 5 mm × 5 mm in size by TV-CDFI was much lower than that by TA-CDFI, with a significant difference (P＜0.001). Color Doppler Flow Imaging (CDFI) showed with the prolonged existence of intrauterine remnants, less blood stream occurred with sparse starlike shape or without blood flow. If the existence of remnants was relatively shortened, blood stream presented dense parse starlike shape. The trophoblast-like blood flow was detected by pulsed wave Doppler, with a resistance index of 0.38-0.55.Conclusions TV-CDFI can detect the abnormal echoic mass and blood flow in the uterus more clearly than TA-CDFI. Therefore, it provides clinicians with more accurate diagnostic support.
