[Surgical and conservative methods for removing mummified fetuses in cattle]

The purpose of this study was to describe the findings and therapy in 4 cows and 1 heifer with mummified fetus. All animals were admitted at the clinic after several unsuccessful therapies with prostaglandin F2alpha and local uterine infusions. All animals were in good condition. In case 1, diagnosis of mummified fetus could not be confirmed after manual rectal palpation and ultrasonography whereas cases 2, 4, 5 all had mummified fetus. In case 3, the fetus was in maceration. Initial therapy consisted of administration of prostaglandin F2alpha and prostaglandin E2 followed by repeated administration of prostaglandin E2. Mummies (length from apex to rump 13-32 cm) could be taken out within 3 to 6 days per vias naturales in cases 2, 4, 5 and in case 3, bones (maximal length 4 cm) could be unhinged. The structure in the uterus of case 1 could not be mobilised and was consequently removed under sight control using colpotomy followed by hysterotomy. Animals 2, 3, 4 and 5 were pregnant on the occasion of telephone inquiry. On the basis of our results, we recommend the conservative medical therapy with PGE2 for cases of mummified fetus. Colpotomy and hysterotomy are reserved as therapy feasible if the use of prostaglandin E2 is not successful.
