  1. RadiographingVeterinary Emergencies Jane MacLellan

  2. Common Veterinary Emergencies • Gastric dilation-volvulus • Hit by car • Intestinal obstruction • Blocked cat • Respiratory distress • Dystocia • Toxicity • Hemangiosarcoma

  3. Radiographing Emergencies • Stabilize first! • Radiographs are not a treatment

  4. Gastric Dilation-Volvulus • Normal stomach • Parallel to ribs on Lateral view • Pylorus on right • Fundus on left

  5. Gastric Dilation-Volvulus • Acute gastric dilation • Stomach distended with gas, fluid, food. • Pylorus and fundus in the normal position • Gastric dilation-volvulus • Stomach is rotated • Pylorus is shifted dorsally and to the left = key to diagnosing GDV • Lateral views are of most value • Left lateral  pylorus filled with fluid • Right lateral  pylorus filled with gas • = Pylorus on left • = GDV • Compartmentalization 

  6. Hit by Car • Thorax • Lung contusions • Pneumothorax • Broken ribs • Hemothorax • Abdomen • Loss of detail

  7. Hit by Car • Musculoskeletal • Fractures • Luxations

  8. HBC - Thorax

  9. HBC - Abdomen

  10. HBC - Musculoskeletal

  11. Intestinal Obstruction • Vomiting, lethargy, anorexia • Dilation of bowel loops orad to obstruction • Longer duration = greater distension • Distal obstruction = greater amount of distended loops • Partial obstructions are less obvious • Frequent vomiting can remove gas/fluid • Mineral/Metal are easily seen • Non-mineralized/metalic objects difficult to see

  12. Intestinal Obstruction • Linear FB • Plicated appearance • Short gas filled tubes • Additional information to confirm obstruction • Serial radiographs • Contrast studies • Barium swallow • Ultrasound

  13. Bone Foreign Body

  14. Linear Foreign Body

  15. Contrast Study

  16. Respiratory Distress • Many differentials • Pneumonia • Congestive heart failure • Pneumothorax • Pleural effusion • Thoracic mass • Radiographs can tell us A LOT

  17. Pneumothorax

  18. Pneumonia

  19. Congestive Heart Failure

  20. Dystocia • Radiographs are useful to detect: • Position of fetus • Size of fetus • Number of fetuses left • Whether fetus is still alive

  21. Dystocia

  22. Blocked Cat • Radiographs shouldn’t be your first step • Unblock the cat first! • Once unblocked, may be helpful • Stones • Crystals • If can’t unblock • Location of the obstruction

  23. Blocked Cat

  24. Blocked Cat

  25. Toxicity • Loss of detail

  26. Toxicity

  27. Ruptured Hemangiosarcoma • Loss of detail • Abdominal mass • Globoid heart - pericardial effusion • Basketball heart

  28. Ruptured Hemangiosarcoma
