“…There are a few controversial reports on the effect of HD on placental function, and it remains uncertain whether HD effects feto-and uteroplacental circulation in a manner that could be detected by measurement of Doppler flow velocity waveforms [25][26][27] . In our series, 1 case of Doppler resistance deteriorated from normal to abnormal.…”

Objectives: To evaluate the effect of intensive fetal surveillance via Doppler ultrasound and fetal non-stress test on the perinatal outcome of pregnant women undergoing an intensified hemofiltration scheme. Methods: Five consecutive pregnancies of women undergoing intensified hemodialysis were analyzed due to the following parameters: maternal background, hemodialysis schedule during pregnancy, blood pressure, occurrence of fetal complications, occurrence of obstetric complications, gestational week at delivery, mode of delivery, and newborn outcome and follow-up. Results: All pregnancies resulted in a live birth, mean gestational age was 32 weeks. Intrauterine growth restriction occurred in 4 fetuses, pathological umbilical artery flow velocity waveforms in 2. The mean birth weight was 1,764 g (range 1,274–2,465 g). Cesarean section was performed in 3 patients because of fetal distress. None of the patients developed severe complications like pre-eclampsia. Conclusions: Although intensified dialysis enables the maintenance of stable uteroplacental and fetal perfusion, intensive fetal monitoring is mandatory to reduce perinatal morbidity and mortality in pregnant women on maintenance dialysis.

“…Fetal renal intra-arterial pressure, various metabolites, and prostaglandins are among the most commonly suspected parameters that may potentially influence renal perfusion and resistance to flow. Weiner et al [4] and Jakobi et al [5] showed a reduction in the uterine and umbilical artery resistance indexes in patients undergoing hemodialysis. However, contrast to these studies, Malone et al [6] demonstrated no significant alterations in uteroplacental ratios of peak systolic blood flow velocity to diastolic veloci-ty.…”

“…Shifts in acute fluid volume, electrolyte imbalances, and hypotension constitute major dialysis-related complications that impair the uteroplacental circulation. The impacts of hemodialysis on the umbilical and uterine artery flow velocities were investigated only in a few cases [4][5][6]. We present the 1st case in whom the results of uteroplacental and fetal renal artery Doppler flow velocimetry performed before and after hemodialysis were evaluated concurrently with those of fetal blood sampling.…”

Maternal-Fetal Factors That Affected Doppler Waveform Analysis in a Patient Undergoing Hemodialysis

Pregnancy in women having chronic renal insufficiency and undergoing hemodialysis is a rare event with a poor outcome. This is the 1st case in whom pre- and posthemodialysis fetal renal artery Doppler flow velocimetry was used in conjunction with fetal blood sampling which was performed to assess fetal karyotype and blood chemistry. Uteroplacental Doppler measurements were also performed, and a close correlation between maternal-fetal blood creatinine and urea nitrogen levels and fetal renal, umbilical, and uterine artery resistance indexes was observed.

“…In another pregnant woman managed by hemodialysis, improvement in the uteroplacental and fetoplacental per fusion following each course of hemodialysis was ob served, suggesting that impaired flow in these vascular beds might be related to metabolic factors as well [5],…”

Dialysis during pregnancy is a rare event associated with a poor outcome. The acute fluid volume shifts during hemodialysis are suspected to be one of the reasons for the high rate of complications during the procedure. This is the first report of uteroplacental and fetoplacental perfusion assessment during acute hemodialysis in pregnancy. The results of the Doppler measurements suggest that the maternal-fetal circulation can successfully tolerate acute volume shifts provoked by hemodialysis.
