Bilateral segmental aplasia of the uterine horns with unilateral pyometra and uterine horn torsion were diagnosed in a Pomeranian bitch that presented with chronic abdominal distension and an acute onset of anorexia and lethargy. Because radiographic and ultrasonographic findings revealed the presence of markedly enlarged bilateral uterine horns filled with fluid in the caudal abdomen, a tentative diagnosis of either pyometra or hydrometra with uterine horn torsion was made. Exploratory laparotomy showed bilateral, segmentally distended uterine horns with unilateral uterine horn torsion. Ovariohysterectomy was performed, and bilateral segmental aplasia of the uterine horns with the development of unilateral uterine horn torsion was diagnosed histopathologically. To the authors' knowledge, this is the first report of uterine horn torsion in conjunction with segmental aplasia of the uterine horn in a bitch. 相似文献

A nine-month-old domestic short haired cat was admitted with the history of acute vomiting, depression and shivering. Abdominal ultrasonography revealed minimum enlargement of the right uterine horn filled with anechoic fluid. On excretory urography, functionally and anatomically normal, enlarged left kidney was found, but right kidney was absent. It was preliminary diagnosed as hydrometra with right renal agenesis. Aiming at the correction of hydrometra, we performed ovariohysterectomy. During spaying, we found a missing segment of distal part of the right uterine horn and absence of ipsilateral kidney and ureter. Compressed uterine structure and segmental aplasia of right uterine horn were found in histopathological investigation. Taken together, it was diagnosed as a segmental aplasia of uterine horn with ipsilateral renal agenesis. 相似文献

A 5-year-old, sexually intact poodle bitch was presented with a 2-year history of inguinal mass. A tentative diagnosis of hydrometra/mucometra with inguinal herniation was made and ovariohysterectomy with hernia repair was performed. Both fluid-filled uterine horns, both broad ligaments, and the uterine body were observed to be herniated through the inguinal ring. On histopathology, marked edema and diffuse hemorrhage were diagnosed in the uterus. 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

The ovarian dynamics and uterine and ovarian blood flows of a 6-year-old (2 parturitions) Holstein Friesian cow with right uterine horn aplasia were observed during two estrous cycles. In one estrous cycle, a corpus luteum (CL) formed in the right ovary, but regression of the CL and subsequent ovulation were not observed. In the other estrous cycle, a CL formed in the left ovary and delayed regression of the CL and subsequent ovulation were observed. The blood velocity of the right uterine artery was lower than that of the left uterine artery throughout both estrous cycles when a CL formed in either the right and left ovary. The blood velocities of the right and left ovarian arteries were unaffected by right uterine horn aplasia and changed depending on the presence of a CL. These results indicated that the blood flow of the right uterine artery was very weak and that aplasia of one uterine horn affects the estrous cycle, especially CL regression. 相似文献

Pyometra in an inguinal hernia was diagnosed in a 10‐year‐old intact cross‐bred bitch which had had dysorexia, depression and inguinal distension. The hernia contained caudal portions of the two uterine horns, uterine cervix and cranial part of the vagina. As the organs were enlarged and full of pus, manual attempt to push back the uterine horns and the vagina in the abdominal cavity through the inguinal canal was unsuccessful. Herniated uterine horns were ligated and cut in their median portion, so it became possible to remove the cervix and the caudal portion of the horns through the hernial orifice, and the ovaries and the cranial part of the horns through a peritoneal midline incision. This bitch was not intended for breeding purposes and, given the presence of a huge pyometra associated with an inguinal hernia, an ovario‐hysterectomy was recommended. Uterine herniation should be considered as a differential diagnosis of a caudal lateral inguinal mass. When pushing the uterus back in the abdominal cavity is impossible, a surgical procedure should be performed to detect ischemia–reperfusion injury and/or a septic risk. 相似文献

A 1.5-year-old female Persian cat was presented for inappetence and azotemia. Ultrasonography and urography revealed multiple abnormalities involving the genitourinary tract, including agenesis of the right kidney and ureter. Gross examination of the abnormal uterus revealed segmental aplasia of right caudal uterine horn causing cranial distension with fluid, a normal left uterine horn, and both normal ovaries. Microscopically, endometrial glands of the right uterine horn were markedly decreased in number. The right uterine horn was hemorrhagic suggesting estrus. This is the first report of this combination of urinary and uterus abnormalities in the veterinary literature. 相似文献

Two Holstein heifers and a cow were diagnosed with White Heifer Disease by ultrasonography. Case 1 was a 14 month-old heifer with aplasia of both sides of the uterine horn. In case 2, a primiparous cow and case 3, an 18 month-old heifer, both showed aplasia of the right uterine horn. Case 2 became pregnant by artificial insemination at ipsilateral ovulatory follicle and corpus luteum in the left ovary, while case 3 became pregnant by embryo transfer at 7 days after oestrus with contralateral corpus luteum in the right ovary. 相似文献

Laparoscopic sterilization techniques, originally developed for use in women, were evaluated in the bitch and queen. In the first study (study I), the uterine horns of 6 bitches and 3 queens were occluded by electrocoagulation or plastic clips. The sites of occlusion were midway along the length of 1 cornus and at the uterotubal junction on the contralateral side. Both procedures effectively occluded the uterine horns, as evidenced by a distinctly visible separation of the reproductive tract. Laparoscopic examination 1 year after surgery revealed an enlarged, thin-walled, and fluid-filled uterine segment cranial to the midcornus occlusion sites in all animals. The contralateral horn was normal in appearance, except for the separation from the ovarian bursa. Three of the bitches developed pyometra (confined to the distended uterine segment) at 24 months, at 53 months, and at 72 months after sterilization, respectively. In a subsequent study (study II), 1 adult and 5 prepubertal bitches were sterilized by laparoscopic electrocoagulation of both uterine horns at the uterotubal junction adjacent to the ovarian bursa. Upon reexamination 1, 2, and 4 years later, the uterine horns of these females were normal in appearance, but were separated from the adjacent ovarian bursae. These females continued to be clinically healthy. Laparoscopic sterilization offers a rapid and safe alternative to ovariohysterectomy and, because of its minor invasive nature, can be performed on young, prepubertal animals. Such a procedure may have particular value as a simple, practical means of sterilizing dogs and cats on a mass basis. 相似文献

A 3-year-old, 920 g intact female guinea pig presented with a 4-month history of nonpruritic hair loss on the ventral abdomen. The physical examination revealed flank and ventral abdominal alopecia, mucoid vulvar discharge, and abdominal distension. Bilateral rounded masses just caudal to the kidneys and structures consistent with enlarged uterine horns were detected on abdominal palpation. Abdominal ultrasound revealed bilateral ovarian cysts, thickened uterine horns, and multiple circular hypoechoic and anechoic structures in the uterine wall. The patient underwent ovariohysterectomy. Gross examination of the uterus revealed a piece of hay in the left uterine horn. A final diagnosis was hormonally active ovarian follicular cysts, cystic endometrial hyperplasia, and purulent bacterial endometritis caused by Escherichia coli, Fusobacterium nucleatum, and Arthrobacter spp. Cystic endometrial hyperplasia is infrequently reported in guinea pigs, and this report describes an associated bacterial endometritis and uterine foreign body with concurrent ovarian cysts. 相似文献

An 11-year-old crossbred Pomeranian bitch displayed a large intramural, well-delineated uterine mass in one horn, near the junction with the uterine body. The mass was composed largely of mature adipose tissue, smooth muscle cells singly and in small clusters, anomalous medium-size and large arteries, and multifocal islands of cartilaginous and osseous tissues. Smooth muscle cells stained positively for desmin, and adipocytes and chondrocytes were positive for S-100 protein. This tumor has histologic and immunohistochemical features compatible with human uterine angiolipoleiomyoma, a rare tumor that has never been reported in the veterinary literature. This benign tumor is believed to be of a choristomatous nature. 相似文献

Spontaneous and drug-induced uterine motility (UM) was recorded in 5 nonanesthetized bitches for 2 to 4 days. Catheter-tip pressure transducers were surgically implanted in 1 uterine horn, tunneled subcutaneously to exit from the skin over the dorsal lumbar area, and protected by a bandage. On the day after implantation, spontaneous UM was recorded in the awake bitch. Effects of IV prostaglandin (PG) F2 alpha (5 micrograms/kg of body weight) and oxytocin (0.05 USP U/kg) and IM PGF2 alpha (25 micrograms/kg) were measured. Estradiol (1 to 25 micrograms/kg) was administered and the study was repeated 24 hours later. In awake bitches, spontaneous UM was 190% greater than UM in anesthetized bitches. Uterine motility was increased by more than 100% after IV PGF2 alpha or oxytocin and by 52% after IM PGF2 alpha. Estradiol abolished spontaneous UM, but did not affect drug-induced responses. Seemingly, spontaneous and drug-induced UM can be documented in the nonanesthetized bitch. 相似文献

This case report describes the clinical course, the diagnostic and therapeutic management as well as histopathological findings in a case of foetal retention for about 5 months in a 5-year-old Boxer. Clinical symptoms included mucosanguinous vaginal discharge and a firm ovoid mass of about duck egg size palpable in mid abdomen. Sonographic examination was not suitable to visualize uterine contents, while radiography revealed a conglomeration of foetal bones focally visible in the right uterine horn, which was surgically removed together with the ipsilateral ovary in order to maintain the fertility of the bitch. After lancing the uterine wall the osseous skeleton as well as parts of hairy skin and muscles of the foetus attaching the uterine wall were detected. Histologically a unilateral necrotizing panmetritis with almost complete destruction of the endometrial structures was diagnosed. Furthermore, the endometrium, the myometrium as well as the serosa revealed a severe trichogranulomatuous inflammation with numerous foetal hairs visible within the inflammatory alterations. After treatment of the bitch with prostaglandin F(2alpha) and an antibiotic agent she became pregnant in the second heat after surgery and gave birth to two healthy puppies. This is the first report on foetal retention for several months followed by unilateral ovariohysterectomy with subsequent recovery of fertility. Furthermore, this case report describes for the first time the histomorphological diagnosis of a unilateral trichogranulomatuous panmetritis in a bitch. 相似文献

A heifer with congenital left uterine horn aplasia had completely normal reproductive cycles when ovulation occurred from the right ovary. Subsequent to ovulation from the left ovary, however, the corpus luteum persisted for months unless prostaglandin F2 alpha was administered. The reproductive tract was examined after slaughter. The left oviduct ended blindly, resulting in fluid-filled cysts. Except for aplasia of the left uterine horn, the reproductive tract appeared to be morphologically normal. This natural model confirms that the luteolytic signal in cattle is sent from the uterine horn to the ipsilateral ovary, but not to the contralateral ovary. Diagnosis of this abnormality required careful palpation per rectum. The normal luteolysis that occurred with exogenous prostaglandin F2 alpha treatment provided misleading information that the heifer was normal. 相似文献

A focal uterine adenomyosis is described in two bitches. In both cases, the uterus showed knobbly enlargements of 4 to 8 cm in diameter, which resulted in distinct clinical symptoms. Other pathological changes of the uterus were not present. One bitch was presented because of a history of vaginal discharge of several months' duration. Radiographs, as well as ultrasonography, revealed a soft tissue lesion at the cervix. The other bitch showed a marked reduction in its general condition and a sudden onset of a tense abdomen. Radiologically, a lesion of soft tissue opacity was observed in the mid-abdomen and was seen to originate from the left uterine horn during exploratory laparotomy. A torsion of the lesion was present, which explained the clinical signs in this second case. 相似文献

Segmental aplasia of the left uterine horn in a multiparous Holstein cow was diagnosed by palpation and ultrasonography. Treatment with prostaglandin was unsuccessful in eliminating the fluid from the distended uterine horn. Segmental aplasia should be included in the list of differential diagnoses for cows with nonresponsive uterine enlargement. 相似文献

Recent reports indicate that Leishmania chagasi has tropism to the male canine genital system, which is associated with shedding of the organism in the semen, supporting the hypothesis of venereal transmission. The aim of this study was to describe the lesions and assess parasite load in the genital system of bitches with canine visceral leishmaniasis (CanL). Symptomatic (n=5) and asymptomatic (n=5) bitches seropositive for CanL were randomly selected at the Center for Zoonosis Control (Belo Horizonte, State of Minas Gerais, Brazil). Five serologically negative, healthy, adult bitches also from the CZC were used as controls. Samples from genital organs (vulva, vagina, cervix, uterine body, uterine horns, uterine tubes, and ovaries), liver, and spleen were histologically evaluated and processed for immunodetection of Leishmania sp., and PCR. The most significant histological change was a mild to moderate vulvar dermatitis, characterized by a histio-plasma-lymphocytic infiltrate. This change was detected in all asymptomatic, four symptomatic, and three uninfected control bitches. In one symptomatic and one asymptomatic bitch intracytoplasmic amastigotes were observed within macrophages in the inflammatory infiltrate. Samples from all the segments of the genital tract were positive in at least one infected animal, in the absence of detectable amastigotes in the tissue. These findings support the notion that L. chagasi does not have genital tropism in the bitch, which is in contrast to our previous findings in naturally infected male intact dogs. 相似文献

Fetal activity and mobility and changes in diameter of the allantoic fluid compartment in the uterine horns were studied in mares between days 69 and 81 of pregnancy by use of transrectal ultrasonography (n = 12) and transcervical videoendoscopy (n = 8). The insertion tube of the videoendoscope was positioned within the allantoic sac to permit viewing of the fetus and entrance to each uterine horn. Each uterine horn was divided ultrasonographically into 3 segments of equal length, and the horns were designated on the basis of side of umbilical attachment (cord vs noncord horns). The diameter of the allantoic fluid compartment in the cornual segments increased (P less than 0.05) over the cranial (18.6 +/- 1.9 mm), middle (35.6 +/- 2.9 mm), and caudal (51.7 +/- 4.4 mm) segments, but differences between cord and noncord horns were not evident. Dynamic changes in diameter of the allantoic fluid compartment in cornual segments (ultrasonography) and at the entrance to each uterine horn (videoendoscopy) were detected (no significant difference between methods). During continuous videoendoscopic viewing (17 to 60 min/mare), extreme changes in allantoic fluid compartment diameter (76 to 100% of maximum to 0 to 25% of maximum or vice-versa) occurred an equivalent of 2.6 times/h/horn entrance; changes had an average duration of 3.4 minutes. A change from 100% (maximal diameter) to 0% (no visible lumen) or vice-versa occurred an equivalent of 1.3 times/h/horn entrance. Sometimes the uterine wall was so closely constricted++ around the fetal-amniotic unit that no intervening allantoic fluid was ultrasonographically detectable whereas at other times the uterus in the same location was widely dilated.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Rapid abdominal enlargement and weight gain occurred in a four-year-old Rhodesian ridgeback bitch in late oestrus. The bitch was nulliparous. Severe cardiovascular dysfunction followed and an exploratory laparotomy was performed. A large, single, spheroid mass weighing 17 kg was located in the middle section of the left uterine horn. A diagnosis of sterile, focal, cystic endometrial hyperplasia was made from gross pathology, histopathol-ogy and bacteriology. The bitch made a complete recovery following an ovariohysterectomy. 相似文献

OBJECTIVE: To compare the bursting strength of a vessel sealant device (VSD) with that of an encircling suture on uterine horns and bodies from dogs. SAMPLE: Uteri from 24 shelter dogs with unknown reproductive histories. PROCEDURES-Uterine horns and bodies were allocated to groups to be sealed with suture or a VSD. Uteri were then infused with saline (0.9% NaCl) solution until the seals burst or the uteri reached a maximal pressure of 300 mm Hg. Variables recorded included dog age, uterine body and horn diameter, and maximal pressure. RESULTS-The median (range) bursting pressure reached in sealed uterine horns was 300 (0 to 300) mm Hg for the VSD group and 300 (200 to 300) mm Hg for the suture group. Within the VSD group, seals of 2 of 3 uterine horns with a diameter ≥ 9 mm burst before intraluminal pressure reached 100 mm Hg, compared with 1 of 21 uterine horns with a diameter < 9 mm. The median bursting pressure for uterine bodies was 237 (0 to 300) mm Hg for the VSD group versus 300 (175 to 300) mm Hg for the suture group. Within the VSD group, seals in uterine bodies with a diameter ≥ 9 mm failed at a significantly lower pressure (125 [0 to 125]) mm Hg than those with a diameter < 9 mm (275 [125 to 300]) mm Hg. CONCLUSIONS AND CLINICAL RELEVANCE-The failure pressure for both sealing techniques was high, which indicated that the VSD may be a safe instrument for sealing the uterine horn in dogs. Given the low mean bursting pressure for seals in uterine bodies with large diameters, the VSD cannot be recommended for sealing uterine bodies ≥ 9 mm in diameter. 相似文献
