The mean placental blood flow was significantly lower in the ligated horns than in the normal horns (108.1 versus 159.4\u2003ml\/minute\/100\u2003ml, p\u2003=\u20030.0004).

These findings could have implications for human studies of placental microcirculation and for the management of disorders related to placental
