In this article we report 3 horses that developed an extraperitoneal abscess after colic surgery at the incision site. All 3 horses presented with nonspecific clinical signs and extraperitoneal abscess was diagnosed from ultrasound evaluations and cytological examination of abscess aspirates. One horse developed dehiscence of the incision after drainage of the abscess through the incision. In 2 cases a small standing paramedian incision was performed through which the abscess was drained and lavaged; complete resolution of the abscess and healing of the incision was achieved in both cases. Extraperitoneal abscess is a previously unreported incisional complication after colic surgery in horses. Early and careful ultrasonographic examination of the abdominal incision is required for diagnosis in cases with nonspecific clinical signs. A paramedian incision through the rectus abdominis muscle into the abscess cavity permitted adequate drainage and debridement of the abscess in 2 cases.  相似文献

A 13-year-old mare presented for evaluation of recurrent colic episodes. The horse was diagnosed with a mass within the spleen at the ultrasound examination of the abdomen; the levels of Serum Amyloid A and the fibrinogen were high and so a presumptive diagnosis of an abscess involving the spleen was made base on clinical, ultrasonographic and laboratory findings and it was decided to perform n exploratory laparotomy for a definitive diagnosis and possible treatment. Upon abdominal exploration a mass involving the spleen, the lateral wall of the ventral colon adherent to the left abdominal wall was diagnosed and with an intraoperative ultrasound examination a linear hyperechoic foreign body was diagnosed within the mass. It was removed through an enterotomy of the left ventral colon that allowed the digital exploration of the mass without spilling of pus within the peritoneal cavity. The horse was discharged and the long term follow-up revealed no complications and no more signs of abdominal pain.  相似文献

A modified parainguinal approach was used to castrate 119 abdominal cryptorchid horses. The operative time ranged from 10 to 30 minutes. Follow-up information was obtained for 107 horses. Swelling, more severe than that expected in routine castrations, was reported in six horses. An incisional abscess had to be drained in one horse and one horse died of unexplained causes 3 days after the surgery.  相似文献

Objective: To describe a novel surgical technique for management of right dorsal colitis in the horse. Study Design: Clinical report. Animals: 14‐year‐old Warmblood gelding. Methods: The horse was referred for treatment of a stromal abscess and signs of right dorsal colitis. Plasma chemistry revealed marked hypoproteinemia. Abdominal ultrasonographic examination showed a thickened right dorsal colon (RDC). Medical treatment was unsuccessful. With the horse in left lateral recumbency under general anesthesia, an approach to the right side of the abdomen through a 16th rib resection was made. The thoracic cavity was entered during the approach. Surgical resection of the RDC and side‐to‐side anastomosis of the diaphragmatic flexure to the small colon (bypass) was performed. The thoracic cavity was closed by attaching the diaphragm to the body wall and air was removed at the completion of surgery. Results: Resection of the RDC and bypass of the resected area was successfully performed. The colic signs and hypoproteinemia resolved. Complications of surgery included a deep surgical site infection with development of a large intrathoracic abscess. The abscess was managed with drainage and long‐term antimicrobial treatment. Conclusion: Right dorsal colitis can be treated successfully with resection and bypass of the RDC. In cases where the thoracic cavity is penetrated during the abdominal approach, the diaphragm should be sutured to the body wall at the beginning of surgery to avoid development of an infection within the thoracic cavity. Clinical Relevance: RDC resection and bypass may be an alternative approach for management of horses with right dorsal colitis.  相似文献

An enostosis-like lesion was diagnosed in the left femur of a Swedish Warmblood horse that had a left hindlimb lameness of 3 weeks duration. With scintigraphy using technetium 99m-hydroxymethylene diphosphonate (99m Tc-HDP) a marked regional focal increase in radioactivity was identified in the medullary cavity of the left femur. Radiographically there was a corresponding focal increase in bone opacity in the middiaphysis of the left femur. Histopathologically, a 5 cm area of bone matrix was present in the diaphysis of the left femur and confirmed as an enostosis-like lesion. Enostosis-like lesions should be considered as a source of pain in horses with difficult to localize, moderate to severe chronic lameness.  相似文献

This Case Report describes a periarticular abscess and a suppurative arthritis of the atlanto-occipital joint in an adult horse. The horse showed a painful swelling localised on the atlanto-occipital region and ataxia in all 4 limbs. During hospitalisation, the horse developed recumbency, dysphagia, facial paralysis and seizures. Ultrasonography of the atlanto-occipital region enabled a tentative diagnosis to be made, which was later confirmed at autopsy. Culture of the abscess revealed a Staphylococcus aureus. However, the horse had a history of recurrent fever, hypertrophy and abscessation of the submandibular lymph nodes, neck pain and dyspnoea for 2 months, which was suggestive of strangles.  相似文献

Medical management was unable to prevent the development of an extrapulmonary abscess in a 10-year-old Thoroughbred gelding with anaerobic pleuropneumonia. Intercostal thoracostomy achieved drainage of the abscess. Resolution of the abscess and subsequent bronchopleural fistulas was monitored by ultrasonography and video-endoscopy. The horse returned to training 4 mo after discharge.  相似文献

A 22‐year‐old Quarter Horse gelding with a history of dental (107) extraction 2 weeks previously was presented with facial cellulitis and an orbital abscess. The abscess was drained surgically dorsally and ventrally to the zygomatic arch and the horse was treated with parenteral antimicrobial and anti‐inflammatory drugs. The affected eye was protected with a temporary tarsorrhaphy and treated via a subpalpebral catheter. Six months after presentation, the horse was in excellent general condition and returned to previous level of exercise but showed blindness on the affected side. Pallor of the optic disc and severe attenuation of the retinal vessels, suggestive of optic disc atrophy, were present.  相似文献

This is the first report of the isolation of Actinomyces denticolens, an opportunistic pathogen, from a draining submandibular lymph node abscess in a horse in Ontario. Due to the similarity of the clinical signs with strangles, this pathogen should be included in the differential diagnosis of submandibular lymphadenopathy in the horse.  相似文献

OBJECTIVE: To report on the outcome of surgical treatment of acute abdominal crises in miniature breed horses. DESIGN: Retrospective case series of miniature horses presented to the University Veterinary Centre, Camden with an acute abdominal crisis. METHODS: Hospital records of all miniature horses that underwent ventral midline laparotomy for acute abdominal crisis between 1997 and 2001 were reviewed. The signalment, history, clinical signs, results of ancillary diagnostic procedures, location and type of intestinal lesion, treatment and outcome were retrieved from each case record. Long-term survival was determined by telephone interview of owners. RESULTS: Eleven miniature horses including five females and six males underwent ventral midline laparotomies for acute abdominal crisis during the study period. Ages ranged between 1 month and 19 years. Surgical findings included faecalith obstruction (seven horses), enterolith (one horse), strangulating lipoma of the descending colon (one horse), jejunal infarction (one horse), and caecal infarction (one horse). Long-term survival rate (minimum 12 months post surgery) was 55%. Six of eight horses with simple intraluminal obstructions survived, while the three horses with gastrointestinal lesions associated with vascular compromise were euthanased either at surgery (caecal infarction), or postoperatively, due to complications (strangulating lipoma of the descending colon, jejunal infarction). Postoperative complications in this study included impaction of the descending colon (two horses), diarrhoea (two horses), peritonitis (one horse), hyperlipaemia (two horses), incisional infection (two horses) and abdominal adhesions (one horse). Hyperlipidaemia was present in five of seven horses in which serum triglycerides were measured at presentation. CONCLUSIONS: Simple intraluminal obstructions of the large intestine were frequently encountered during exploratory laparotomy in miniature horses presented for acute abdominal crises, and their surgical treatment was associated with a good prognosis. In contrast, this study suggested that abdominal pain associated with vascular compromise of gastrointestinal tissues in miniature horses was associated with a poorer prognosis, consistent with reports in other horse breeds. Possible contributing factors to faecalith formation, including poor quality roughage, dental disease, and inadequate water consumption, should be recognised and avoided in miniature horses. Serum triglyceride concentrations should be measured in miniature horses presented for acute abdominal pain. If elevated, nutritional supplementation should be provided.  相似文献

A large abscess in the lateral neck region of a horse was treated with percutaneous drainage. The abscess was localized with ultrasonography and aspirated by use of a 7.7-cm spinal needle. A stainless-steel guide wire was passed through the needle, and tissue dilators were used to enlarge the percutaneous hole. A multiperforated polyvinylchloride catheter that was placed within the abscess cavity permitted aspiration and lavage of the abscess. The abscess resolved over the next 10 days with no complications. Percutaneous abscess drainage is commonly performed in people and may have application in veterinary medicine.  相似文献

Retropharyngeal infections in five horses   总被引:2,自引:0,他引:2  
Five horses with retropharyngeal (RP) infections had clinical signs of dysphagia and/or dyspnea. Diagnosis was confirmed, using pharyngeal endoscopy and lateral radiography of the pharynx. One horse responded to surgical drainage of a RP abscess and was sound at light work. One horse responded to medical management after the site of infection was surgically explored. Two horses recovered after medical management; the RP abscess of 1 of these 2 horses ruptured spontaneously into the pharynx and the other horse became racing sound. The fifth horse remained dysphagic and had left laryngeal hemiplegia after medical treatment.  相似文献

The case of a 2‐year‐old gelding with acute onset of preputial swelling and prolapse is presented. After initiating conservative management using a penile repulsion device, the horse repeatedly displayed signs of mild abdominal discomfort with sudden deterioration to an episode of violent colic after 5 days of hospitalisation. Ultrasonographic examination of the preputial swelling at that time demonstrated the presence of small intestine between the internal and external laminae of the prepuce and led to the diagnosis of a direct preputial hernia. The contents of the hernia were readily reduced through a defect in the ventral abdominal wall after the anaesthetised horse was placed in dorsal recumbency. The historical information, clinical progression and surgical findings were supportive of an acquired ventral abdominal wall defect. To the authors' knowledge, this is the first reported case of a direct preputial hernia associated with an acquired ventral abdominal wall defect.  相似文献

This case report discusses a successful partial splenectomy for treatment of a splenic abscess in a horse. A 2-year-old Thoroughbred colt was hospitalised 5 weeks after an episode of severe colic that was followed by gradual weight loss and anorexia, pyrexia for 5 days and dehydration on the day of referral. A large splenic abscess was identified ultrasonographically. Following initial medical treatment, an exploratory laparotomy was performed. Multiple adhesions were released and a partial splenectomy conducted to remove the abscess. Migrant metallic wires penetrating from the small intestine into the splenic parenchyma were found to be the cause for the adhesions and the abscess. This paper summarises the potential advantages of utilising a partial vs. a total splenectomy and highlights the potential complications of these surgical procedure in equines.  相似文献

Real-time ultrasound was used to identify a foreign-body abscess causing an extraluminal esophageal obstruction in the neck of a horse. Surgical exploration to remove the foreign body and drain the abscess was performed after 2 months of medical management that had failed to resolve the problem. The abscess could not be visualized because there was no draining tract or other localizing sign of inflammation. Ultrasound was used aseptically to guide surgical dissection to the walled off abscess with minimal damage to adjacent vital structures in the surgical field. The signs of esophageal obstruction abated and have not recurred in 15 months.  相似文献

In the case presented, a young horse was referred for further evaluation based on a presumptive diagnosis of pulmonic valve endocarditis, bronchopneumonia and a cranial mediastinal abscess based on thoracic ultrasound, echocardiography and clinical signs. However, further echocardiographic evaluation revealed that the abscess was compressing the right ventricular outflow track causing outflow obstruction, a murmur associated with right ventricular outflow tract obstruction (acquired pulmonic stenosis) and right ventricular hypertrophy. Vegetative endocarditis was not present. Medical management was unsuccessful, but surgical drainage and long‐term antimicrobial therapy were effective and the horse returned to a successful racing career.  相似文献

Impactions are the most common problem affecting the small colon in horses and are much more prevalent in ponies and miniature horses. Ventral midline laparotomy under general anaesthesia is the standard of care for this condition when medical management fails to resolve the impaction or when the impaction causes complete intraluminal obstruction and tympany. This case series reports the use of standing flank laparotomy (SFL) in 15 ponies with focal small colon impactions and one large breed horse with an elongated small colon impaction. All cases presented with signs of colic of 1–4 days' duration. The horses were initially vigorously treated with both enteral and parental fluids but failed to pass faeces, with no resolution of abdominal distention or pain. In all cases, a definitive diagnosis was made during SFL and the small colon appeared to be viable. The impaction was resolved by extraluminal massage. In the horse and in one pony, in addition to extraluminal massage, high enema was administered during surgery. Routine perioperative treatment with fluids, analgesics, antimicrobials and wound care was provided. All animals survived to discharge. The time from surgical resolution of the impaction to passing faeces was less than 2 h in all but one case. Median duration of hospitalisation was 2 days and all animals returned to their original use by 2 months. The encouraging results of this case series suggest that SFL is a viable alternative to ventral laparotomy for ponies and horses with either focal SCI or extensive SCI.  相似文献

Whole blood containing 59Fe-labeled erythrocytes (RBC) and unlabeled serum was transfused from a donor horse on 2 occasions into each of 6 recipient horses. Survival of transfused cells was monitored in the recipients as a function of time after transfusion by measuring RBC radioactivity in the recipients. After the 1st transfusion, RBC concentration of 59Fe remained at 60% to 100% of the transfused dose for 4 days, after which radioactivity values dropped to less than 10% of the dose by 6 days in 3 horses. In the 3 other horses, RBC radioactivity dropped immediately after transfusion, reaching minimal values in approximately 48 hours. After the 2nd transfusion, 1 horse retained 80% of the dose in circulating RBC for 4 days; 2 horses demonstrated a rapid loss of circulating radiolabeled RBC, reaching minimal values in 48 hours; and 2 horses demonstrated minimal radioactivity in the RBC mass even immediately after the transfusion. One horse died of anaphylactic shock during the 2nd transfusion. Erythrocyte compatibility tests, using the direct agglutination test, the antiglobulin test, and the hemolytic test, were not effective in predicting survival of transfused RBC.  相似文献

History, physical examination, and bone scintigraphy were used to diagnose central and/or third tarsal bone trauma in 3 acutely lame horses. In all 3 cases, the results of initial radiographic examination were negative. Bone scintigraphy revealed focal, intense radioisotope uptake at the level of the distal tarsal bones in the 3 horses. Radiographs obtained 4 weeks after injury in one horse demonstrated a slab fracture of the central tarsal bone. Conservative management of the tarsal bone disease resulted in acceptable return to function in all 3 horses.  相似文献

A 9-year-old Quarter horse was presented for chronic refractory pneumonia. On necropsy, an hepatic abscess, caudal vena cava thrombosis, pulmonary thromboembolism, and embolic pneumonia were identified. Similar lesions have been reported in cattle as caudal vena cava thrombosis syndrome, however this syndrome has not previously been reported in horses.  相似文献
