A multiparous pregnant Welsh Pony mare was examined because of anorexia, dyspnea, and a large abdomen. Ultrasonography of the uterus revealed an excessive amount of amniotic fluid surrounding the fetus. Transabdominal ultrasonography permitted differentiation of hydrops amnii from hydrops allantois. The mare aborted a 7-month-old fetus with brachygnathia and a large, edematous umbilical cord. Hydrops amnii, an excessive accumulation of amniotic fluid in the amniotic cavity, is most commonly reported in cattle and sheep.
一匹经产怀孕的威尔士母马因厌食、呼吸困难和腹部肿大而接受检查。子宫超声检查显示胎儿周围羊水过多。经腹超声检查可区分羊膜积水和尿囊积水。这匹母马流产了一个7个月大的胎儿，胎儿有短颌畸形和粗大、水肿的脐带。羊膜积水是指羊膜腔内羊水过度积聚，最常见于牛和羊。
