Abstract:

Objective

To investigate the value of three-dimensional power Doppler ultrasound (3D-PDUS) in estimating renal perfusion in pregnant women with severe preeclampsia.

Methods

From June 2016 to August 2017, 3D-PDUS and Virtual Organ Computer-aided Analysis (VOCAL) technique were applied in 34 pregnant women with severe preeclampsia (observation group) and 36 normal pregnant women (control group) in Jiangyin people's Hospital. Parameters for renal perfusion, including vascular index (VI), vascularization flow index (VFI) and blood flow index (FI), were calculated and compared between the two groups.

Results

Both VI [(48.211±7.369)% vs (60.751±5.893)%, t=7.835, P<0.01] and VFI (11.753±1.743 vs 16.273±2.749, t=8.264, P<0.01) showed statistically significant difference between severe preeclampsia group and control group. The results indicated that renal perfusion decreased in severe preeclampsia. There was no statistically significant difference for FI between the observation group and the normal group.

Conclusion

3D-PDUS technique plays an important role in evaluating renal perfusion in pregnant women with severe preeclampsia.
