The value of color Doppler ultrasound in the differential diagnosis of rupture of corpus luteum and ectopic pregnancy rupture
Objective To analyze the value of color Doppler ultrasound in the differential diagnosis of rupture of corpus luteum and ectopic pregnancy(EP)rupture.Methods The data of 53 patients with EP rupture(EP rupture group)and 52 patients with rupture of corpus luteum(rupture of corpus luteum group)were retrospectively analyzed.Both groups of patients were examined by a color Doppler ultrasound,and the ultrasound detection indicators,as well as hemodynamic parameters and blood flow performance of the two groups of patients were compared.Results In EP rupture group,the ovarian volume by color Doppler ultrasound was(5.38±1.50)cm3,the abnormal echo region diameter was(3.24±1.50)cm,and the depth of the liquid dark region was(5.07±1.82)cm,which were all smaller than(7.62±2.08)cm3,(7.42±1.86)cm and(6.40±1.76)cm in rupture of corpus luteum group(P<0.05).In EP rupture group,the peak systolic blood flow velocity by color Doppler ultrasound was(12.08±3.23)cm/s,which was lower than(15.56±4.08)cm/s in rupture of corpus luteum group;EP rupture group had pulsation index of(0.94±0.25)and resistance index of(0.56±0.10),which were greater than(0.65±0.18)and(0.34±0.07)in rupture of corpus luteum group(P<0.05).The incidence of annular or semicircular color Doppler flow imaging in the EP rupture group was 16.98%,which was lower than 73.08%in rupture of corpus luteum group;the incidence of strip and dot appearance were 32.08%and 50.94%,which were higher than 11.54%and 15.38%in rupture of corpus luteum group(P<0.05).Conclusion Color Doppler ultrasound has significant differential diagnostic value for rupture of EP and corpus luteum,and is suitable for clinical application and promotion.
