Abstract：【Objective】To explore the value of the differential diagnosis of transvaginal ultrasonography by different positions in unruptured tubal pregnancy and luteal cyst of pregnancy.【Methods】Forty-three cases of unruptured tubal pregnancy (group A) and 47 cases of luteal cyst (group B) were selected to compare the size of pregnancy mass and corpus luteum, the thickness of the circumferential wall, the blood flow distribution, the blood flow spectrum and the relationship between the mass or cyst and ovarian position after position change.【Results】In the group A, the size of mass or gestational sac and the thickness of circumferential wall were (2.44 ±1.50) cm and (0.71 ±0.22) cm, respectively. There was no significant difference between the group A and the group B (3.01 ±1.44) cm and (0.68 ±0.23) cm (P>0.05). The blood flow signals in the group A were mostly dot or strip, while those in the group B were mostly circular or semi-circular. There were significant differences in the proportion of circular, dot and strip blood flow signals (P<0.05); the RI value of the group A was (0.49 ± 0.09), which was significantly lower than that of the group B (0.58 ±0.11), and the difference was statistically significant (P<0.05); the blood flow spectrum of the group A was mostly very low resistance or low resistance, while that of the group B was mostly low resistance. The blood flow spectrum of patients showed low resistance and high resistance. The proportion of blood flow spectrum with very low or high resistance was significantly different between the two groups (P<0.05); the position of mass or gestational sac and the ovary of the same side changed in the group A (37/43), while that of the group B and the ovary of the same side remained unchanged (47/47). There was a significant difference between the two groups (P<0.05).【Conclusion】Unruptured tubal pregnancy and luteal cyst of pregnancy have different blood flow signals and spectrum, and the position change is different from the position of the ovary on the same side. Its characteristics are helpful to improve the early detection rate of tubal pregnancy, which is worthy of clinical reference.
