OBJECTIVE: To assess the ability of colour/pulsed Doppler ultrasound to detect failed physiologic change of the spiral arteries in pregnancies complicated by pre-eclampsia.
DESIGN: Prospective matched-pairs case controlled study.
SETTING: Tertiary referral teaching hospital.
SAMPLE: Sixteen women with severe pre-eclampsia and 16 normotensive controls.
METHODS: Colour/pulsed Doppler assessment of blood flow in the uterine arteries and spiral arteries in central and peripheral parts of the placental bed.
MAIN OUTCOME MEASURES: Impedance to blood flow in the spiral arteries in pre-eclamptic group compared with normotensive controls.
RESULTS: In women with pre-eclampsia there is significantly higher impedance to blood flow in spiral arteries compared with normotensive women.
CONCLUSIONS: Ultrasound colour/pulsed Doppler based investigation of blood flow in the spiral arteries in ongoing pregnancy can detect failed physiological change of these vessels in pre-eclampsia. This is in concordance with histologic data.
