Abstract:Objective To explore the differences in arterial blood flow dynamic of the bilateral tubal
pregnancy patients during early pregnancy, this research mainly adopted the transvaginal color Doppler
(TVCD) ultrasonic detection rate of patients with the endometrial spiral artery. Methods Totally 99
cases of early pregnancy patients from obstetrics clinic and inpatient in our hospital were selected. The
rate of spiral artery presentation, endometrium thickness and bilateral tubal artery were detected by
TVCD and the hemodynamics parameters were measured by pulse Doppler (PD), such as peak systolic
velocity (PSV), end diastolic velocity (EDV) and resistivity index (RI). Contrast analysis the correlation
between the testing results and eventually pregnancy outcomes. Results In the 99 total cases, 3 groups
were divided as 42 cases of intrauterine pregnancies, 38 cases of ectopic pregnancies, and 19 cases
of spontaneous abortions. The endometrial thickness of the three groups was compared. Intrauterine
pregnancies group was thicker than ectopic pregnancy group and spontaneous abortion group, and
the difference was statistically significant (P<0.05). There was no significant difference between the
spontaneous abortion group and the ectopic pregnancy group (P>0.05). In the intrauterine pregnancy
group, 27 patients had arterial blood flow within the endometrium, the rate of spiral artery presentation
was 64.2%; in the ectopic pregnancy group, only 1 patient had areas of endometrial blood flow, and 37
did not; 26.3% of the spontaneous abortion patients had arterial blood flow within the endometrium,
the differences among the three groups were significant (P<0.05). In the ectopic pregnancy group, the
tubal artery flow signal of TP side was abundant and bright compared to the other in 29 cases. The RI
of TP side were lower than the other side, the EDV were higher than the other side (P<0.05), while no
difference was shown in PSV (P>0.05). The hemodynamic parameters of tubal artery between sides hadno significant difference in intrauterine pregnancy group (P>0.05). Conclusion TVCD has important
clinical value for the diagnosis of early ectopic pregnancy by testing the thickness of endometrium and
spiral artery within endometrium. The abnormal implantation in ectopic pregnancy can cause more blood
flow changes in the adjacent supplying vessels. The differences of the hemodynamic parameter of the
bilateral tubal artery can provide additional information for the diagnosis of tubal pregnancy.
