الملخص الانجليزي
Hydrops of the fetal membranes is one of the pathological disorders of pregnant animals in different species including sheep, goat, and cow. It can be defined as dropsical condition of the fetal sacs in which there is an increase in the production of fetal fluids with excessive accumulation in the fetal sacs. Causes of hydrops include genetic, placental, and hepatic or renal fetal circulation defects. Hydrops conditions affect the dam and the fetus as well. These conditions are likely associated with genetic or congenitally deformities in the fetus (es). The etiology of hydrops-associated congenital malformations is not clear because of the complex mechanisms that may be involved. Fetal mummification means fetal death at the middle or last third of gestation without regression of the corpus luteum due to genetic defects, torsion of umbilical cord, placental defects or infections, the presence of high circulating progesterone leads to retention of the fetus (es) with subsequent absorption of the fetal fluids resulting in a parchment-like fetal membranes resulting in papyraceous mummification. A three-years and sixth-months-old full-term pregnant Rahmani ewe (parity = 2; body weight = 45 kg) was introduced to Veterinary Teaching Hospital, Faculty of Veterinary Medicine, South Valley University, Egypt. It showed bilateral excessive round-shape abdominal distention with strong straining and colic. Upon thoroughly obstetrical examination it revealed failure of dilatation of the most caudal cervical ring. After successful surgical interference, 6 dead fetuses were delivered; 3 mummified fetuses and 3 fully-developed dead malformed fetuses with ankyloses, brachygnathy, and inferior arthrogryposis.
