Amnioinfusion and Bed Rest May Effectively Improve the Insufficient Circulation of the Umbilical Cord in Pregnant Women With Hyper-Coiled Cord and Oligohydramnios.

We experienced two cases with hyper-coiled cord in which fetal-umbilical-placental circulation was improved after amnioinfusion or bed rest. Therefore, amnioinfusion and bed rest to reduce the compression of the vulnerable umbilical cord in cases of hyper-coiled cord might improve the pathologic fetal-umbilical-placental circulation.
