A 10-year-old castrated male Standard Poodle presented with an acute onset of lethargy and abdominal pain. The animal had a history of traumatic splenic rupture requiring splenectomy 5 years previously. Surgical exploration revealed multiple cystic red nodules involving all liver lobes, several of which were submitted for histopathology. Microscopically, the cystic nodules were dilated bile ducts and lymphatics surrounded by ectopic splenic tissue. A diagnosis of intrahepatic splenosis was made. 相似文献

Small intestine strangulation by pedunculated lipomas is a common cause of acute colic in horses. However, diagnosis of this condition prior to surgery may be difficult due to the poor specificity of the clinical signs. We describe the ultrasonographic findings of 2 horses presented for acute colic with a diagnosis of strangulating lipoma confirmed in surgery. Lipomas were identified as rounded and well‐defined, homogeneous hyperechoic structures, surrounded by distended small intestine loops and peritoneal fluid. Ultrasonographic identification of lipomas should be attempted during an abdominal scan, especially in horses with evidence of small intestinal ileus and/or obstruction. 相似文献

Two, young adult, male pugs presented for spontaneous left-cranial lung lobe torsions. Clinical signs associated with these two cases included increased weakness, increased respiratory effort, tachypnea, acute collapse, lethargy, anorexia, and cyanosis. The torsed lung lobes were excised using a thoracoabdominal stapling device without detorsing the lobes. Both dogs recovered uneventfully, and at least one year postoperatively, no clinical abnormalities were noted by their owners. Results of this report suggest that spontaneous lung lobe torsion in pugs occurs and should be a differential diagnosis for pugs with increased respiratory effort, tachypnea, nonproductive cough, acute collapse, cyanosis, and lethargy. Surgical excision may be curative. 相似文献

A four-year-old, entire male whippet was presented with a three-day history of lethargy, inappetence, occasional retching, a soft cough and intermittent episodes of haemoptysis. Clinical and laboratory findings, and thoracic radiographic and ultrasonographic studies suggested a diagnosis of lung lobe torsion. A concurrent lung lobe torsion of the right cranial and right middle lung lobes was confirmed at exploratory thoracotomy. Management included resection of both the affected lung lobes. No obvious underlying aetiology for the condition was apparent. The dog made a full recovery from the procedure and at the time of writing (11 months postoperatively) was reported to be well, exercising normally and showing no breathing abnormalities. 相似文献

Five adult dogs presented for an acute onset of seizure activity. Magnetic resonance imaging revealed lesions in the olfactory bulbs, frontal lobes of the cerebrum, or both. A modified bilateral transfrontal sinus craniotomy was performed on each patient. The goal of removing the lesion was to relieve clinical signs and to provide tissue for histopathological diagnosis. In each instance, excision of the lesion was possible using this approach. No postoperative complications were observed. The modified bilateral transfrontal sinus craniotomy provides excellent access to the canine olfactory bulbs and frontal lobes. 相似文献

An unusual case of acute abdominal distress caused by necrotizing lymphadenitis of the retroperitoneal lymph nodes in a 10-year-old Springer Spaniel is presented. The retroperitoneal lymph nodes were severely distended, but no other abnormalities were found in the abdominal cavity or elsewhere. Biopsy revealed acute necrotizing lymphadenitis, which should be considered in the differential diagnosis of acute abdominal disorders in the dog. 相似文献

Malignant neoplasia in 4 alpacas was characterized by acute onset of clinical signs and rapidly deteriorating condition. Postmortem examination revealed metastatic or multicentric neoplasia in the abdominal organs of alpacas 1, 3, and 4 and an extensive thoracic mass in alpaca 2. Immunohistochemical stains supported a diagnosis of B-cell lymphosarcoma in alpacas 1-3 and a neuroendocrine neoplasm in alpaca 4. 相似文献

The results of preoperative examination, surgical intervention and the outcome of 50 cases of acute abdominal crisis in the horse are presented. Pre-surgical parameters discussed in this correlative study include duration of the condition prior to sergery, pulse rate, packed cell volume (PCV), abdominal distention, intestinal motility and tympany, rectal findings, reflux of fluid after passage of a nasogastric tube, and abdominal paracentesis. A retrospective study was performed to evaluate the usefulness of each clinical parameter in deciding that a case was surgical, arriving at a specific pre-surgical diagnosis, and in giving a prognosis. Rectal examination was the single most useful diagnostic tool. Reflux of gastric fluid through the nasogastric tube usually indicated obstruction of the small intestine. 相似文献

A 2-year-old intact male Cane Corso dog was presented for acute weakness, vomiting, and diarrhea. Abdominal ultrasound revealed the stomach had severe wall edema and a target appearance. Computed tomography was consistent with a gastro-gastric intussusception and concurrent mineral-like gastric foreign bodies. After reduction of the intussusception, bilateral incisional gastropexy was performed to prevent recurrence. True gastrogastric intussusception is a rare condition and should be considered if the stomach has severe wall edema with a target sign on abdominal ultrasound. Computed tomography was useful to confirm this rare diagnosis and screen the entire abdomen for concurrent lesions.Key clinical message:This case highlights the usefulness of a CT examination to confirm this rare diagnosis, to determine the position of gastric compartments, and to detect potential concurrent lesions prior to surgery. 相似文献

A clinical diagnosis of acute pancreatitis is often difficult to obtain. Histopathology remains the gold standard, whereas clinical signs, diagnostic imaging and laboratory testing, even in combination, may be insufficient. In a prospective study, lipase activity in ascitic fluid of various aetiologies was determined in 44 dogs in order to investigate its performance in cases of acute pancreatitis. Data of simultaneously determined blood lipase activities were available in 27 dogs. Lipase activity was measured by a colorimetric assay. A complete peritoneal fluid analysis was performed. Dogs were divided into four groups, according to their final diagnosis: acute pancreatitis (A), abdominal trauma (B), abdominal neoplasia (C) and others (hepatic or cardiac diseases) (D). Dogs with acute pancreatitis had a significantly higher peritoneal lipase activity than those in other groups (P < or = 0.024), while no significant difference was found between the other groups (P > or = 0.734). Blood lipase activity as well as protein content and total cell count of the ascitic fluid did not show any significant difference between groups. Data show that determination of lipase activity in dogs that develop ascites may be useful in complementing the diagnosis of acute pancreatitis. 相似文献

Gastrointestinal failure occurs as a consequence of a number of clinical syndromes in neonates including ischemic, distention, inflammatory, and degenerative injury. Failure of this organ system may manifest as diarrhea, ileus, abdominal pain, obstipation, and weight loss. There are numerous causes of gastrointestinal failure in foals; however, the principles of assessment are similar for most causes. The history can be helpful in formulating and focusing the differential diagnosis list. For example, rupture of the urinary bladder is a more likely cause of colic in a foal with progressive abdominal distention that is less than one week of age than in a foal that is 1 month of age. A farm history of current or past enteritis indicates that a medical cause of colic is more likely than a surgical cause; however, distinguishing between medical and surgical causes is challenging. An onset of clinical signs at or just after birth indicates the possibility of a congenital problem. Colic caused by retained meconium must be considered because of the high prevalence of the condition. This article considers the methods used to assess foals with gastrointestinal failure and highlights age-related differences. The principles of initial treatment of foals with gastrointestinal failure are also discussed. Because the clinical condition of neonates can deteriorate rapidly, initial assessment may entail therapeutic intervention to stabilize the patient before a diagnosis is confirmed. Therapeutic intervention may include intravenous or enteral administration of fluids and electrolytes, provision of caloric requirements, prevention or treatment of hypogammaglobulinemia, prevention of infection, and alleviation of pain. The treatment and supportive care of a foal with diarrhea differ from those of a foal with acute abdominal pain associated with other causes. In cases of diarrhea, nonspecific treatments can be implemented before a causative diagnosis is established. 相似文献

A 2-year-old spayed female ferret (Mustela putorius furo) was presented with a 2-day history of ambulatory paraparesis of the hind limbs. On physical examination a mass was palpated in the cranial abdominal region, caudal to the stomach. A complete blood cell count revealed a normocytic normochromic anemia and reactive lymphocytes. A hypoechoic abdominal mass was observed during an ultrasound examination of the abdomen. An exploratory laparotomy was recommended and performed during which a pyramidal mass resembling a lobe of fatty liver tissue, plus omental torsion, was removed. The histopathologic diagnosis of the surgically removed mass was splenosis. The abdominal pain and ambulatory paraparesis resolved after surgery, which suggests that the paraparesis was due to pain. The findings in this report indicate that splenosis should be included as a differential diagnosis when a ferret presents with an abdominal mass and acute abdominal pain. 相似文献

The presentation of a patient with acute abdominal pain often is both a diagnostic and therapeutic challenge for the veterinary practitioner. Rapid physical examination and assessment of the patient's cardiovascular status are critical to initiating appropriate and often aggressive medical management as diagnostic tests are being performed. A number of diagnostic tests can be performed, including complete blood count, serum biochemistry profile, serum amylase and lipase, abdominal radiographs, abdominal ultrasound, abdominal paracentesis or diagnostic peritoneal lavage, cytology, and fluid analysis. In some cases, surgical exploration may be indicated, depending on each patient's clinical signs and response to therapy. Of the most important aspects of medical management of the patient with acute abdominal pain is to maintain oxygen delivery to tissues and to treat aggressively for pain or discomfort. The initial triage and approach to the patient with acute abdomen are discussed. 相似文献

Diagnostic laparotomy and laparoscopy are surgical techniques commonly used for the investigation of chronic abdominal disease and weight loss. They can both be usefully carried out in the standing sedated horse, allowing a thorough examination of the dorsal abdominal cavity and biopsies to be harvested. Small intestinal disease is an important cause of weight loss and recurrent colic. Inflammatory or neoplastic bowel disease may not always be apparent grossly and histopathological assessment of full thickness biopsies may be required to provide a definitive diagnosis. Details of cases of 15 horses that underwent small intestinal biopsy or enterectomy while sedated and standing are presented. Three incisional infections occurred causing delayed wound healing. Three horses were subjected to euthanasia before hospital discharge: two had persistent gastric reflux and one had colitis. A further six were subjected to euthanasia in the first 4 months due to their underlying inflammatory bowel condition. One horse was subjected to euthanasia for severe laminitis that was presumed to be caused by treatment with a corticosteroid 4 years later, and one died of acute colic 2.3 years after successful resection and anastomosis. Five horses were alive at the time of review, median 2.7, range 1.2–4.3 years. Overall therefore, 3 (20%) horses died during hospitalisation and 5 (33%) were still alive at the end of the study. Results from this series suggest that minimising the number of intestinal biopsies may reduce morbidity, but the underlying pathological process appears to be the most important prognostic factor for survival. Resection and anastomosis in the standing sedated horse proved feasible. 相似文献

Canine patients with acute abdominal signs are often clinically unstable and need a rapid and accurate diagnosis. Contrast‐enhanced multi‐detector computed tomography (CT) is the current modality of choice for evaluating acute abdominal pain in people. We hypothesized that contrast‐enhanced multi‐detector CT would be a feasible and safe technique for use in awake and lightly sedated dogs with acute abdominal signs. Eighteen client‐owned dogs were enrolled, all presenting with acute abdominal signs. Dogs were scanned using a dual‐phase protocol that included precontrast, arterial, and portal venous phases. Eight dogs were scanned awake and ten were given light sedation as chosen by the primary care clinician. Two observers who were unaware of clinical findings and sedation status scored image quality for each scan by consensus opinion. Mean serum creatinine in the sedated group was higher than in the awake group but was within the normal reference range. Other laboratory and physiologic measures did not differ between awake and sedated groups. No IV contrast‐related adverse reactions were seen. Median scan time for all patients was less than 10 min. Sixteen of 18 contrast‐enhanced multi‐detector CT scans were scored fair to excellent in diagnostic quality, with no statistical difference in diagnostic quality for awake vs. sedated patients. Causes for two poor quality diagnostic scans included severe beam hardening from previously administered barium contrast agent and severe motion artifacts. We conclude that dual‐phase contrast‐enhanced multi‐detector CT is a feasible and safe technique for evaluating awake and minimally sedated dogs presenting with acute abdominal signs. 相似文献

An ingested metallic foreign body migrated from the stomach and induced restrictive pericarditis in a horse. Necropsy revealed chronic abdominal and acute thoracic lesions. Although rare, ingested foreign body migration should be considered in the differential diagnosis of body cavity disease in horses. 相似文献

Contrast‐enhanced multi‐detector computed tomography (CE‐MDCT) is used routinely in evaluating human patients with acute abdominal symptoms. Contrast‐enhanced ultrasound (CEUS) continues to be in its infancy as it relates to evaluation of the acute abdomen. The purpose of this study was to compare survey radiography, B‐mode ultrasound, CEUS, and CE‐MDCT findings in canine patients presenting with acute abdominal signs; with a focus on the ability to differentiate surgical from non‐surgical conditions. Nineteen dogs were prospectively enrolled. Inclusion required a clinical diagnosis of acute abdominal signs and confirmed surgical or non‐surgical causes for the clinical signs. Agreement for the majority of recorded imaging features was at least moderate. There was poor agreement in the identification of pneumoperitoneum and in the comparison of pancreatic lesion dimensions for B‐mode vs. CEUS. The CT feature of fat stranding was detected in cases including, but not limited to, gastric neoplasia with perforation, pancreatitis, and small intestinal foreign body. Ultrasound underestimated the size and number of specific lesions when compared with CE‐MDCT. Contrast‐enhanced ultrasound was successful in detecting bowel and pancreatic perfusion deficits that CE‐MDCT failed to identify. Accuracy for differentiation of surgical vs. non‐surgical conditions was high for all modalities; 100%, 94%, and 94% for CE‐MDCT, ultrasonography and survey radiography respectively. Findings indicated that CE‐MDCT is an accurate screening test for differentiating surgical from non‐surgical acute abdominal conditions in dogs. Focused CEUS following CE‐MDCT or B‐mode ultrasonography may be beneficial for identifying potentially significant hypoperfused lesions. 相似文献

Nonstrangulated colonic displacement was diagnosed by exploratory celiotomy in 32 horses with acute abdominal pain. Clinical signs progressed slowly and included evidence of mild to moderate abdominal pain, good cardiovascular status, reduced intestinal sounds, and normal peritoneal fluid, and resembled those of colonic impaction. In most horses, rectal palpation supported a diagnosis of colonic obstruction but not a diagnosis of colonic impaction. 相似文献
