Introduction: Impaired uteroplacental perfusion causes fetal growth restriction. Our work aims to treat fetal growth restriction by increasing uteroplacental perfusion. Using Doppler ultrasound we previously showed significantly increased uterine blood flow (UBF) 5 days after adenovirus vector-mediated overexpression of vascular endothelial growth factor (VEGF) in the uterine artery. This study investigated the long-term effect of this vector.
Methods: We implanted ultrasonic flow probes (Transonic Inc, USA) around both uterine arteries in mid-gestation pregnant sheep (n = 6, 90 days of gestation,
