This paper describes a case of uterine fibrosarcoma in an 18-year-old Warmblood mare. The mare had exhibited bloody fluid accumulation inside the uterus and vaginal haemorrhagic discharge since the previous foaling. The mare was euthanized, and on pathological examination, in addition to the uterine neoplasia, multiple metastases were found in the lungs, liver and spleen. The histological and immunohistochemical examination determined that the tumour was a fibrosarcoma. To our knowledge, this is the first paper to describe a uterine fibrosarcoma in a mare. 相似文献

A 2-year-old Arabian filly was referred for evaluation of a serosanguineous vaginal discharge. Palpation per rectum revealed a large, fluid-filled uterus and a uterine mass. The filly developed septic metritis and secondary laminitis as a result of torsion and necrosis of a pedunculated uterine mass. Ovariohysterectomy was performed. The entire cervix was removed with the uterus. Gross examination of the excised uterus revealed 3 intraluminal masses. Histologic evaluation identified the tumors as fibroleiomyoma. The filly recovered completely, and there was no recurrence of the tumor. 相似文献

A pregnant mare with a history of prolonged gestation (～515 days) and suspected diagnosis of fetal mummification was examined. Rectal palpation revealed that the left broad ligament of the uterus was dorsal and medial to the right uterine ligament and it was not possible to observe the cervix during vaginal examination. Transabdominal ultrasound revealed fluid in the uterus, fetal membranes and the uterine walls defined and thickened. Free fluid was not seen in the peritoneal cavity. Laboratory tests (blood cell count and clinical chemistry) were normal. Based on clinical history, physical examination and ultrasound findings, a chronic uterine torsion with fetal death was diagnosed and the mare was subjected to exploratory celiotomy. The uterus was strongly adhered to the peritoneum of the ventral abdominal wall and there were multiple adhesions to the colon. Hysterotomy was performed to remove the fetus and to permit repositioning of the uterus. When the fetus was removed, a large devitalised grey tissue area of the right ventral uterine horn was observed. Multiple adhesions prevented a rescue hysterectomy and euthanasia of the patient was performed. During the necropsy, a 180° cranial cervix clockwise uterine torsion was observed. This rare case of uterine torsion appears to be the most chronic case reported in the equine literature. 相似文献

A 13‐year‐old pluriparous Dutch Warmblood mare presented to Utrecht University's Department of Equine Sciences 4 weeks after suspected abortion at 3.5 months gestation, to investigate the nature of a uterine mass and persistent vulval discharge. Transrectal ultrasonographic examination revealed copious flocculent fluid and fetal remnants within the uterus and a 5–6 cm heterogenous mass in the uterine wall at the tip of the right horn. Expulsion of fetal parts and resolution of the coexisting endometritis were effected by a combination of repeated PGF2a analogue injections to induce oestrus, application of PGE2 gel to aid cervical relaxation, and daily uterine lavage and antibiotic instillation. The presence of the mass in the uterine wall was confirmed by hysteroscopy and the suspected tumour subsequently removed by partial laparoscopic ovariohysterectomy under standing sedation and local anaesthesia. The histological appearance of the tumour was consistent with a leiomyoma or moderately malignant leiomyosarcoma. Although a follow‐up examination 6 months post surgery revealed uncomplicated healing of the uterus, the owner decided to retire the mare from breeding. Uterine neoplasia is an extremely unusual cause of fetal death in the mare but, in the present case, laparoscopic partial ovariohysterectomy proved a promising, minimally invasive technique for salvaging sufficient uterus to make subsequent breeding a realistic proposition. 相似文献

A 19-year-old Quarter Horse mare was evaluated because of bloody vaginal discharge that was apparent immediately following breeding. On transrectal ultrasonography, it was evident that the uterus was filled with fluid containing echogenic particles; linear hyperechoic structures were also visible. Endoscopy was performed, which revealed a number of bones adhered to the cranial wall and floor of the right uterine horn as well as purulent fluid in both uterine horns. Bacterial endometritis and fetal maceration were diagnosed. The mare was treated with antibiotics, and the fetal bones were manually removed from the uterus. Fetal maceration with intrauterine retention of bones is rare in mares. Use of hysteroscopy supplements ultrasonography in the diagnosis of uncommon conditions of the uterus. Macerated bones may be adhered to the endometrium, thereby requiring manual removal. 相似文献

An 18-year-old mare, 285 days pregnant, was evaluated for apparent abdominal pain of 8 hours' duration. A large volume of sanguinous fluid was obtained on abdominocentesis, and digital vaginal examination revealed a dilated cervix and blood in the uterus. Abdominal palpation per rectum revealed the uterus to be large and distended with fluid. Ultrasonography revealed a dead fetus on the floor of the cranial portion of the abdomen. The mare was euthanatized, and necropsy confirmed that the uterus had ruptured, and that the fetus, within its chorioallantois, was in the abdomen. The amniotic sac contained approximately 96 L of amniotic fluid. Torsion of the amniotic sac separated the fetus from the fluid-filled compartment. Hydramnios was diagnosed on the basis of the excessive amniotic fluid and was believed to be the cause of the uterine rupture. 相似文献

A 11-year-old, female, spayed greyhound was presented with a haemorrhagic discharge from the vulva. Clinical examination, vaginoscopy and a computed tomography scan showed an irregular egg-sized mass in the region of the cervix and uterine stump. An endoscopic grab biopsy (incisional) suggested a malignant mesenchymal tumour. Following this, surgical excision of the cranial vagina, cervix and the uterine remnant was performed. The final diagnosis of haemangiosarcoma was based on histological examination of the larger excisional biopsy specimen and was confirmed by positive immunolabelling of the neoplastic endothelial cells for the von Willebrand factor. 相似文献

A 15-year-old Standard-bred mare was examined because of signs of abdominal discomfort in late gestation. Palpation per rectum revealed tight broad ligaments above and below the uterus, with the right broad ligament running across the top of the uterine body down toward the left, ventral side of the abdomen. A diagnosis of counterclockwise uterine torsion was made and surgical correction was approached via a left, flank laparotomy with the horse standing. The uterus was repositioned and a uterine tear encompassing 180 degrees of the uterine surface was found in the lateral, uterine body just cranial to the cervix. A live colt was delivered vaginally after uterine repositioning and the laparotomy incision was closed. The uterine tear was then repaired via a blind, vaginal approach. The mare was discharged 10 days after surgery. Repair per vaginum of a uterine tear is presented as an alternative treatment in cases for which the tear is recent, abdominal contamination is minimal, and the tear is easily accessible from the vaginal approach. 相似文献

In this study we examined seven queens with normal oestrous cycles and a history of infertility after normal matings. We performed clinical examination, vaginal cytology, evaluation of oestradiol, progesterone and total T4 levels, vaginal bacterial culture, ultrasonography, and serum analyses for detection of antibodies against chlamydia and feline leukaemia virus (FeLV) antigenemia. Ovariohysterectomy (OHE) was recommended for 1/7 queens because of pathological uterine changes detected at ultrasonography and clinical examination. Four out of seven queens were treated with antibiotics and two of these had more litters. One of the queens that were treated was not mated again and one was mated without conceiving and was at a later OHE found to have degenerative uterine changes. No treatment was given and no diagnosis could be established in 2/7 queens. Both of them were later ovariohysterectomised and one showed degenerative uterine changes while the uterus of the other queen could not be obtained for follow-up. In summary, 4/7 cats were diagnosed with uterine pathology and no definitive diagnosis could be established for 3/7 queens. 相似文献

This Case Report describes severe complications associated with uterine prolapse in a mare. A 6‐year‐old Trakehner mare was examined for depression, moderate pain and vaginal discharge 3 days after correction of a uterine prolapse. The clinical examination and haematology revealed that the mare had an infection with systemic inflammatory response syndrome and shock. Due to the uncontrollable, persistent pain, an exploratory celiotomy was performed which revealed severe metritis. During anaesthesia, the mare developed severe cardiovascular compromise and died in recovery. In previously reported cases of uterine prolapse in the mare, the authors warn of uterine injury, broad ligament haemorrhage, metritis, endotoxaemia and laminitis but often have a successful outcome with conventional therapy. This case describes a mare that developed severe complications and death after uterine prolapse. Mares with uterine prolapse require appropriate treatment and vigilant monitoring post treatment to prevent life threatening complications. 相似文献

In this report, we describe the diagnostic findings and outcome of a uterine B cell lymphoma in a mare. A well circumscribed uterine mass with significant peripheral vascularisation was identified by transrectal ultrasonography during the reproductive examination of an 8‐year‐old Thoroughbred mare. Subsequent hysteroscopy revealed that the uterine mass was located intramurally and contained a protruding polyp‐like structure. A diagnosis of uterine B cell lymphoma was established by histopathological examination of a hysteroscopically‐obtained tissue sample. Additional diagnostics demonstrated that the uterus was a site of metastasis. Due to her deteriorating condition, extensiveness of the tumour and poor prognosis, the owner decided that the mare should be subjected to euthanasia. 相似文献

Two American Paint Horses, a 3-year-old nulliparous mare and a 7-year-old primiparous mare, presented for recent infertility and a pre-breeding examination, respectively. Examination of the internal reproductive tract of both mares using transrectal palpation and ultrasonography revealed the presence of the cervix, uterine body, left uterine horn and bilateral ovaries. The right uterine horn could neither be palpated nor imaged. The clinical diagnosis of uterus unicornis in one mare was confirmed at necropsy, which revealed combined aplasia of the right uterine horn and oviduct. 相似文献

A five‐year‐old female cat weighing 3 kg was presented by the owner after noticing a large pink, bilobed mass protruding through the vulva during labour. The cat was in good condition, with appropriate lactation, and the newborn kittens were nursing normally. The uterus was not reverted or invaginated at examination, and there was rupture of the mesovarium, mesometrium and uterine‐vaginal connection around the cervix. Manual reduction of the prolapsed uterus was not possible because of torn ligaments. A coeliotomy was performed to remove the ovaries, and the apex of the uterine horns was passed by the vaginal route. The remaining part of the mesometrium was disconnected, and the prolapsed uterus was removed. The queen and kittens were discharged from the hospital on the second day after surgery. An unusual feature of this case is that the prolapse was complete, without eversion of any part of the uterus through a vaginal tear. 相似文献

Seventeen cases of spontaneous, partial or total vaginal rupture, in pregnant ewes, involving the dislocation and herniation of the intestines and uterus, were studied. Four of them also had a uterine torsion, and three of these recovered after treatment. In the remaining 13 cases the condition of the uterus was unknown. The lesion always consisted of a dorsolateral tear in the vagina with a partial or total perforation of the wall close to the uterine cervix. The affected animals were all in normal body condition. Their average age was just under five years, and most were carrying twins. Most cases occurred approximately one week before expected lambing. None of the cases was observed to have a vaginal prolapse before the vaginal rupture. Histological examination of one case revealed scar formation in the vaginal wall close to the rupture, which appeared to be due to an earlier inflammatory process or injury. The circulatory disturbance in the reproductive organs caused by the uterine torsion potentially weakens the vaginal wall. This weakness, in combination with excessive tenesmus resulting from increased tension in the uterine ligaments, and in some cases possibly with a lower vaginal resistance due to previous scarring, may be of aetiological significance in spontaneous vaginal rupture. 相似文献

This case report describes an uncommon case of a congenitally incompetent cervix and a resulting pneumouterus in a 5‐year‐old maiden Quarter Horse mare. The mare was presented for artificial insemination at the Clinic for Animal Reproduction, Freie Universität Berlin, Germany. Routine vaginal and rectal examinations revealed a shortened cervix of 3 cm length and a dilated uterus filled with a considerable amount of air. During ultrasonographic examination, ovaries of normal size with regular cyclic activity were detected. Chromosomal analysis could not confirm any genetic anomalies such as an expected XO karyotype. The mare was excluded from breeding due to its anatomical constitution. 相似文献

This short communication describes the case of partial foetal retention in an 18-month-old female French bulldog following induction of abortion owing to an undesired mating. Abortion was induced with aglepristone administered in two consecutive protocols of a dual injection 1 day apart. After failure of the first treatment to achieve abortion, 15 days later, a second treatment was administered. Delivering of aborted foetus occurred 2 days after the last administration. Five weeks after the abortion, the female showed a weak haemorrhagic vaginal discharge. On ultrasound examination, the presence of uterine wall distension as well as a puppy skull inside the uterus was observed. This clinical case makes clear that although aglepristone is a very reliable drug, follow-up of the female during treatment and in the immediate post-partum is necessary to ensure a good outcome. 相似文献

An 8-year-old grey Arabian mare was presented for reproductive evaluation with a history of failing to become pregnant during two previous breeding seasons. An enlargement was identified on the right uterine horn on rectal examination which was confirmed as a fluid-filled nonechogenic mass on ultrasonography. Subsequent examination procedures and laparotomy revealed an old hematoma in the wall of the uterine horn. 相似文献

Persistent purulent endometritis in a mare was attributed to an unclassified species of Corynebacterium. Following intrauterine infusions of 20% betadine for 5 days the purulent vulval discharge ceased and the mare appeared clinically normal. Based on histological examination of endometrial biopsy samples, the severe acute inflammatory reaction had largely resolved 2 days after therapy. Three maiden mares considered resistant to bacterial endometritis received single intrauterine inoculations of 1.8 X 10(9) colony-forming units of the Corynebacterium species. The uterine response was followed by vaginal speculum examinations, uterine cultures and cytology, and endometrial histology. After an acute inflammatory reaction, each mare had recovered completely within 2 weeks. Most rapid recovery occurred in the mare in estrus at the time of inoculation. Subsequent secondary infections were detected in two mares. The uncertainty of correlations between results obtained by various diagnostic techniques emphasized the problems associated with each. This report illustrates the concept that endometritis in individual mares may relate more to as yet unidentified "mare factors" controlling uterine defense than to primary invasion by bacteria. 相似文献

A 13‐year‐old Quarter Horse mare presented for evaluation of chronic intermittent colic. Following extensive diagnostics, abdominal radiographs revealed two round, radiopaque objects in the caudal abdomen. Palpation per rectum and transrectal ultrasonography of the reproductive tract confirmed that the round objects were uterine marbles. Dinoprost tromethamine (Lutalyse, 5 mg i.m. q. 24 h for 2 days) was administered to bring the mare into oestrus, and both uterine marbles were manually removed from the uterus following digital dilation of the relaxed cervix. Follow‐up with the owner 12 months after discharge revealed that the mare had shown no further signs of abdominal discomfort since having the uterine marbles removed. To the authors' knowledge, this is the first published report of chronic intermittent colic attributed to uterine marbles in a mare. 相似文献

A 13‐year‐old Romanov sheep presented for evaluation of vaginal discharge, depression and anorexia. Blood work demonstrated mature neutrophilia and marked hyperlactatemia. Transrectal and transabdominal ultrasound revealed echogenic fluid (pus) within the uterus. Purulent uterine fluid culture yield Escherichia coli. A diagnosis of pyometra was made. After medical treatment without clinical improvement, an exploratory laparotomy was performed, and a 360‐degree uterine left horn torsion was identified with the pyometra and multiple corpora lutea on both ovaries. Ovariohysterectomy was performed and the ewe recovered uneventfully. 相似文献
