The history, clinical signs, results of diagnostic imaging, treatment methods and outcome of 16 adult horses with a metallic foreign body in the tongue are reviewed. All the horses had a swollen tongue, they salivated excessively and were partially to completely anorexic. Less common clinical signs were fever, an enlarged and painful intermandibular space, dysphagia, unilateral tongue paralysis and halitosis. Most of the horses had shown clinical signs for less than 24 hours. The foreign bodies were diagnosed by oral examination, radiography and ultrasonography; they were removed from the tongue of four of the horses during the initial oral examination, and were removed surgically from nine others; the other three horses were treated medically without attempts being made to extract the foreign bodies. Twelve of the bodies were small pieces of wire and one was a hypodermic needle. All the horses received a combination of antimicrobial and non-steroidal anti-inflammatory drugs and they all made an uneventful recovery. Feeding hay and the use of cable-framed tractor tyres as feeders were commonly associated with the cases.  相似文献

Seven horses with metallic foreign bodies in the mouth or pharynx were examined at the Colorado State University Veterinary Teaching Hospital from 1983 to 1989. The horses had variable clinical signs, such as purulent nasal discharge, swelling of the throatlatch area, and dyspnea. Most of the horses had clinical signs for more than 2 weeks, and had no or only temporary improvement with conservative medical treatment (antibiotics, nonsteroidal anti-inflammatory drugs). The definitive diagnostic test in all of the cases was radiography, which also aided in the plan for surgical removal of the foreign body. Once the foreign body was removed from each of the horses, their clinical signs resolved. Most of the foreign bodies were small pieces of wire, the sources of which could not be determined, but that may have been incorporated in baled hay.  相似文献

A question frequently asked by clinicians who are treating small animals suspected of having gastrointestinal foreign bodies is whether one imaging test such as survey radiography or ultrasonography is sufficient to make the diagnosis. A study was undertaken to try and answer this question. Survey abdominal radiography and ultrasonography was performed on 16 small animals (11 dogs, five cats) with clinical signs of an obstruction because of a confirmed gastrointestinal foreign body. The majority of the foreign bodies (14/16) were confirmed by surgical removal and were located in the small intestine. A gastric foreign body was retrieved endoscopically and a colonic foreign body was passed in the feces. Radiographically identifiable foreign bodies were evident in nine animals. Small intestinal overdistension was present radiographically in seven animals. Ultrasonography detected a foreign body in all 16 animals. The foreign bodies were identified by their distal acoustic shadowing and variable degrees of surface reflection. An intestinal perforation was detected sonographically but not radiographically. The value of additional sonographic findings including thickening of the gastrointestinal wall and loss of layering, free peritoneal fluid, and lymphadenopathy in these animals is discussed. The findings in this series suggest that in a small animal with a gastrointestinal foreign body, ultrasonography alone could be used to make the diagnosis and may be a more appropriate choice than survey radiography.  相似文献

Two mares, aged 15 and 21 years, were examined because of urinary incontinence, intermittent hematuria, and urine scalding. On admission of both horses, physical parameters were within normal limits and urine scalding of the skin at the ventral perineum was noted. Transrectal palpation and cystoscopy revealed a large type I cystolith (>10 cm) with associated hyperemia and focal ulceration of the bladder mucosa. In horse 1, hemogram, serum biochemical analysis, and renal ultrasound were not performed because of owner finances. In horse 2, results from hematological and serum biochemical analysis were unremarkable and renal ultrasonography did not reveal any abnormalities. Pneumatic impact lithotripsy in a laparoscopic retrieval pouch was performed under cystoscopic guidance after caudal epidural anesthesia, with the horses standing and under sedation. A laparoscopic retrieval device was passed alongside a flexible endoscope into the urinary bladder and the cystolith was manipulated into the pouch. A customized single stainless-steel rod scaler attached to an air compressor was used for fragmentation of the cystolith contained within the retrieval pouch. Lithotripsy time was 42 minutes for horse 1 and 31 minutes for horse 2. Both horses were released from hospital the day of surgery. Both horses were continent and voided normal streams of urine for the duration of the follow-up periods of 27 and 19 months for horse 1 and horse 2, respectively. Pneumatic impact lithotripsy in a laparoscopic retrieval pouch provided a time-efficient and minimally invasive surgical treatment option for removal of large cystoliths in mares.  相似文献

Use of Intraoperative Ultrasonography in Six Horses   总被引：2，自引：0，他引：2  
Intraoperative ultrasonography was used in six horses to aid localization and removal of bone fragments (3 horses) and foreign bodies (3 horses). The ultrasound transducer was enclosed in a sterile sleeve containing sterile aqueous gel and the examination was performed after aseptic preparation of the surgical site. Using ultrasound guidance a needle was placed in contact with the bone fragment or foreign body and an incision was made along the path of the needle to expose and remove the object. This technique resulted in decreased operative time and minimal tissue dissection.  相似文献

Foreign bodies in the soft tissues are frequent problems in both veterinary and human medical practice. Radiography has been the principle tool for diagnosis, but is unable to define many foreign bodies. This study was undertaken to compare the sonographic and radiographic visualization for a variety of foreign bodies. Fresh turkey muscle (pectoral and thigh) with skin was used as the soft tissue model. Assorted foreign bodies were introduced 1 cm into the muscle. Materials examined were small wood fragments, steel wire, glass, nails, graphite, rock, BB pellets, and polystyrene plastic. Following introduction of the foreign bodies radiographs were obtained and the specimens were studied sonographically at 5.0 mHz and 7.5 mHz. All foreign bodies were visible with sonography. A bright echo with either acoustic shadowing or reverberations was present for all specimens. Radiographically metallic foreign bodies were visible but wood, some graphite, and plastic were not seen. We conclude that radiography should remain the primary imaging modality for foreign body detection because of its general availability and low cost. If radiography is negative ultrasound can detect and guide the removal of radiolucent foreign bodies.  相似文献

Objective— To report use of a magnetic retriever for arthroscopic removal of a metallic foreign body from the equine talocrural joint.
Study Design— Clinical report.
Animals— A 2-year-old Warmblood stallion.
Methods— A metallic foreign body was removed from a talocrural joint using a 10-mm magnetic retriever under arthroscopic guidance. Preoperative radiographs were used to locate the intra-articular position of the foreign body.
Results— Six months after surgery, the horse was no longer lame.
Conclusions— A magnetic retriever can be used for arthroscopic removal of metallic foreign bodies from the equine talocrural joint.
Clinical Relevance— A magnetic retriever may be useful for arthroscopic retrieval of metallic foreign bodies from synovial cavities in horses, especially when direct observation is impeded by inflamed synovial villi and fibrin.  相似文献

A submental approach using a 5, 7.5 and 10 MHz mechanical sectorial transducers was used to evaluate the ultrasonographic appearance of the normal and abnormal canine, feline and equine tongue. Seven normal animals were used to characterize the in vivo normal ultrasonographic appearance of the oropharynx. Consistently seen anatomical landmarks included the lingual parenchyma, lingual artery, soft and hard palate interfaces, mandible, basihyoid bone and sublingual musculature. Seven fresh canine, feline and equine cadavers were dissected to confirm the ultrasonographic findings. Seven animals with signs of ptyalism, dysphagia, halitosis and visible lingual lesions were also studied. A foreign body and abscesses secondary to a penetrating wound were detected in a horse. Ultrasound guidance aided surgical dissection, removal of the foreign body and intraoperative drainage of the abscesses. Ultrasound provided valuable non-invasive documentation of the architecture, size and margins of six lingual neoplasms. Ultrasonographic monitoring of the response to the treatment of lingual lesions may be beneficial in the management of patients.  相似文献

Ultrasonography in veterinary practice represents a method that nowadays is a approved component of the examination of small and large animals. Although sometimes more difficult than in small animals, ultrasonography can be often useful in horses. In the present report two cases demonstrate the possibility of sonography in the diagnostic of foreign bodies in soft tissues in horses.  相似文献

Exodontia is the typical treatment recommended in severe cases of dental disease where alternative treatment techniques fail to salvage the affected tooth. Exodontias are frequently performed in the standing horse with the benefit of sedation and regional anaesthesia in order to avoid the risks and expense of general anaesthesia. The inferior alveolar nerve block is commonly utilised when extracting diseased mandibular dentition. Because of the close anatomical relationship of the lingual and inferior alveolar nerves both may be desensitised following anaesthesia of the inferior alveolar nerve. Desensitisation of the tongue may result in horses traumatising it during mastication before sensation returns. This report describes 3 horses that sustained self‐inflicted lingual trauma following inferior alveolar nerve blocks performed for standing oral surgical procedures.  相似文献

Twenty-five small animal patients presenting with signs of orbital disease were investigated using magnetic resonance imaging (MRI) in an attempt to assess the value of this imaging technique for diagnosis. All patients were also examined using ultrasonography, and skull radiography was performed in 20 of these animals. The final diagnoses included neoplasia, inflammatory disease and foreign body penetration. MRI produced detailed images of orbital tissues and provided more information about the extent of pathology than the other imaging techniques; a correct diagnosis based solely on the MRI scan was made in 22 cases. Radiography was found to be helpful only in cases in which neoplastic disease extended markedly beyond the confines of the orbit into the nasal chamber and paranasal sinuses. Radiographic changes other than soft tissue swelling were not evident in other orbital disease processes. Ultrasonography gave both false negative and false positive diagnoses for neoplastic masses, although it allowed the correct diagnosis of both cases of foreign bodies and one of the three cases of retrobulbar abscesses in this series. MRI is recommended for patients in which radiography and ultrasonography fall to produce a confident diagnosis or for which surgery is proposed.  相似文献

This study was made on 24 camel fetuses of crown‐rump vertebral length (CVRL) ranging from 10.5 cm to 105 cm CVRL (94–352 days old). These camel fetuses were classified into three groups representing the three trimesters of prenatal life. During the first trimester (94–142 days), lingual papillae (circumvallate and lentiform papillae) were demonstrated on the lingual root, but lingual body and the apex were almost free of papillae except for some scattered epithelial projections especially near the lateral borders of the body. In the second trimester (152–229 days), the lentiform papillae covered the entire root of the tongue except for areas occupied by the circumvallate papillae. Taste buds with clear pores were observed for the first time in areas between the circumvallate gustatory furrow and surface epithelium of the tongue. In addition, short numerous filiform papillae were observed on the rostral part of the lingual body and the lateral parts of the apex. Fungiform papillae, however, were demonstrated amidst the filiform papillae. In this trimester, taste buds were also seen on the top of the fungiform papillae. In the third trimester (256–352 days), all lingual papillae were clearly demonstrated on the dorsum of the root, body and apex of the tongue. Both types of gustatory papillae (circumvallate and fungiform) had well‐developed taste buds. Mechanical papillae (filiform and lentiform) were well developed. Lentiform papillae occupied most of the dorsal aspect of the Torus linguae; they were larger in size with semicircular apices. Filiform papillae, however, were numerous and demonstrated heavily on the lateral and rostral parts of the body as well as on the apex of the tongue.  相似文献

The clinical, diagnostic and therapeutic features of a horse with a wooden foreign body embedded in the deep portion of the right masseter muscle adjacent to the right orbit are presented. The purpose of this report is to describe the clinical presentation, magnetic resonance imaging findings and treatment of a penetrating wooden foreign body in a horse that had no history of trauma or evidence of a puncture wound. This report documents the usefulness of magnetic resonance imaging to detect a wooden foreign body embedded in the soft tissues of a horse with a chronic copious ocular discharge. Two surgical procedures were necessary, which is a frequent complication encountered with wooden foreign bodies.  相似文献

A 16‐year‐old Italian Saddle Horse gelding was referred for treatment of an incisional hernia that developed 7 months after a ventral midline laparotomy for treatment of acute abdominal pain. Physical examination revealed a hernia approximately 20 cm long and 15 cm wide on the ventral aspect of the abdomen. Ultrasonography revealed the dimensions of the hernia ring to be approximately 15 cm in length and 10 cm in width. A single‐port laparoscopic incisional hernia repair using an operating 0° laparoscope was performed with an appropriately sized (24 × 18 cm) piece of mesh fixed in place with simple interrupted transabdominal sutures. At 4 weeks post operatively, follow‐up physical examination and ultrasonography confirmed healing of the surgical site with no evidence of hernia recurrence. The same evaluation was done 6 months post operatively, and the horse returned to its previous level of activity 8 months post operatively. In horses, laparoscopic application of mesh should be considered among the treatment options for incisional hernia. In the present case, this technique was performed with a single port using an operative laparoscope, in contrast to the multiportal techniques reported previously. The case presented here demonstrates that single‐port laparoscopic herniorrhaphy is feasible, and allows proper placement of an expanded polytetrafluoroethylene intraperitoneal mesh in horses  相似文献

The African giant pouched rat is a nocturnal, fossorial and omnivorous wild rodent widely distributed in sub‐Saharan Africa. The morphology of lingual surface has not previously examined and was investigated by gross dissection, stereomicroscopy, scanning electron and light microscopy. Grossly, it was elongated and dorso‐ventrally flattened with rounded tip. It measured 3.48 ± 0.33 cm in length, with a median groove of 1.4 ± 0.1 cm in length and well‐developed lingual prominence. Stereomicroscopically, filiform, fungiform and vallate papillae were indicated in the apex, body and root. Fungiform papillae intermingled with filiform on the ventral and dorsal surface of the apex and body. Three vallate papillae were located in triangular arrangement on the root. The surface ultrastructural features distinguished four types of filiform which varied in size, shape and distribution: first type with long pointed process was preponderant on the apex and body of tongue; the second with robust base was located on central lingual prominence; the third (caudal body) was conically shaped with pointed process; and the fourth type (root) had forked filamentous process. Large oval‐shaped fungiform papillae were apparent. Each vallate was surrounded by a circumferential groove into which taste pores opened. Histologically, the tongue surface displayed moderately keratinized stratified squamous epithelium, and lamina propria that varied in places. Fungiform and vallate showed spindle‐shaped taste buds. Serous and mucous acini containing neutral and acidic mucins were observed in lamina propria of root. The structural adaptations of the tongue to omnivorous diet and food manipulation in oral cavity were comparatively discussed.  相似文献

A cross‐sectional study was performed on acutely vomiting dogs to compare the accuracy of radiography and ultrasonography for the diagnosis of small‐intestinal mechanical obstruction and to describe several radiographic and ultrasonographic signs to identify their contribution to the final diagnosis. The sample population consisted of 82 adult dogs and small‐intestinal obstruction by foreign body was confirmed in 27/82 (33%) dogs by surgery or necropsy. Radiography produced a definitive result (obstructed or not obstructed) in 58/82 (70%) of dogs; ultrasonography produced a definitive result in 80/82 (97%) of dogs. On radiographs, a diagnosis of obstruction was based on detection of segmental small‐intestinal dilatation, plication, or detection of a foreign body. Approximately 30% (8/27) of obstructed dogs did not have radiographic signs of segmental small‐intestinal dilatation, of which 50% (4/8) were due to linear foreign bodies. The ultrasonographic diagnosis of small‐intestinal obstruction was based on detection of an obstructive lesion, sonographic signs of plication or segmental, small‐intestinal dilatation. The ultrasonographic presence or absence of moderate‐to‐severe intestinal diameter enlargement (due to lumen dilatation) of the jejunum (>1.5 cm) was a useful discriminatory finding and, when present, should prompt a thorough search for a cause of small‐intestinal obstruction. In conclusion, both abdominal radiography and abdominal ultrasonography are accurate for diagnosing small‐intestinal obstruction in vomiting dogs and either may be used depending on availability and examiner choice. Abdominal ultrasonography had greater accuracy, fewer equivocal results and provided greater diagnostic confidence compared with radiography.  相似文献

Intestinal obstruction due to foreign body ingestion is one cause of colic in horses. Although it occurs more frequently in juveniles, adult horses also may be affected. The small colon is a common location in which foreign bodies can be found. Depending on the location of the obstruction in the small colon, different techniques to dislodge the foreign body toward areas where it can be safely exteriorized and removed can be attempted. Alternatively, different approaches to the abdomen can be performed to facilitate exteriorization of the obstructed segment and removal of the foreign body. This paper describes a case of large and small colon obstruction in an adult horse caused by two distinct foreign bodies. The large colon obstruction was removed through a pelvic flexure enterotomy using the ventral midline approach, and the small colon obstruction was removed through a small colon enterotomy using a paramedian approach. Information regarding signalment, history, clinical signs, surgical treatment, and follow-up status of the horse are described.  相似文献

This report describes the clinical manifestations, diagnosis and minimally surgical intervention of a cat with an intraorbital foreign body. A spayed female cat of unknown age was presented with a recurrent cutaneous sinus tract of the left suborbital region. The cat had not vocalized at all since the adoption. A sharp-edged radiopaque foreign body was visualized on dental radiography. Computed tomography outlined the length of the foreign body from the intraorbital soft tissue to the pharynx. The foreign body was removed under the guide of C-arm fluoroscope with minimal skin incision. The surgical site healed completely on the 11th postoperative day, and the cat vocalized normally after healing.  相似文献

Histology of the tongue, including apex, root and body, in four adult Caspian miniature horses was examined. Serial sections with 6 mum thickness were stained with haematoxylin-eosin and Masson trichrome and studied under light microscope. The tongue was covered by stratified squamous epithelium. It was thick and keratinized bearing numerous lingual papillae on the dorsum, mostly filiform with a very fine keratinized thread projecting above the surface and bending backward. The fungiform papillae were sparsely scattered among the filiform papillae and covered with keratinized squamous epithelium. Few taste buds were detected on it. The two very large vallate papillae were detected on the dorsum, just rostral to the root, which were covered with stratified squamous epithelium with relatively high amounts of taste buds in the epithelium of the surrounding grooves. The foliate papillae were present near the palatoglossal arch and had a few taste buds. The epithelium covering the ventral surface of the tongue was thin and keratinized. The lingual muscle core consisted of transverse, longitudinal and perpendicular bundles of skeletal muscle fibres. Clusters of minor salivary glands were present between the muscle fibres and lamia propria. Most of the lingual glands were mucous and most of the gustatory ones were serous type. The mid-dorsal special structure of the tongue (dorsal lingual cartilage) contained sparse skeletal muscle fibres and was rich in white adipose tissue. Hyaline cartilage, routinely observed in this structure in the horses, was not detected in Caspian miniature horse.  相似文献
