Hemometra
As Hämometra (from Greek. Αἷμα (haima) " blood " and μέτρα (metra) " uterus ") refers to a collection of blood in the uterus of animals. In women, this is known as the hematometra .
Emergence
In dogs, a haemometra occurs primarily after hormone- related disorders of the occlusion of the blood vessels between the placenta and uterus or injuries to the uterine lining in difficult births . It then occurs in the first six weeks after the birth. But also tumors , ulcer inflammations of the uterus and hormonally active ovarian tumors can trigger a haemometra.
In relatives of guinea pigs and rabbits , a haemometra develops mainly due to hormonal cycle disorders via glandular-cystic hyperplasia of the endometrium and thus independent of births. In rabbits, adenocarcinomas of the uterus can also trigger a haemometra.
Clinical picture
Lighter forms show up as slight vaginal bleeding and do not cause general well-being. In moderate forms, pain, fatigue and loss of appetite can occur.
A high-grade hemometer, on the other hand, is a life-threatening emergency. The bleeding can lead to severe general disorders with anemia , shock or even bleeding to death.
therapy
Slight forms can be approached conservatively in dogs. Ergotamine , oxytocin , calcium and vitamin K are used to stop the bleeding . The administration of depot progestins ( medroxyprogesterone , chlormadinone ) is also promising.
In the case of heavier bleeding, in the case of guinea pigs and rabbits in general, removal of the ovaries and uterus ( ovariohysterectomy ) is indicated. With severe hemometry and shock symptoms, the circulation must first be stabilized. If the dog has severe anemia , blood transfusions may be necessary before and after surgery.
