Common Veterinary Emergencies Gastric dilation-volvulus Hit by car Intestinal obstruction Blocked cat Respiratory distress Dystocia Toxicity Hemangiosarcoma
Radiographing Emergencies Stabilize first! Radiographs are not a treatment
Gastric Dilation-Volvulus Normal stomach
Parallel to ribs on Lateral view Pylorus on right Fundus on left
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
Hit by Car Thorax
Lung contusions Pneumothorax Broken ribs Hemothorax
Abdomen Loss of detail
Hit by Car Musculoskeletal
Fractures Luxations
HBC - Thorax
HBC - Abdomen
HBC - Musculoskeletal
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
Intestinal Obstruction Linear FB
Plicated appearance Short gas filled tubes
Additional information to confirm obstruction Serial radiographs Contrast studies
Barium swallow Ultrasound
Bone Foreign Body
Linear Foreign Body
Contrast Study
Respiratory Distress Many differentials
Pneumonia Congestive heart failure Pneumothorax Pleural effusion Thoracic mass
Radiographs can tell us A LOT
Pneumothorax
Pneumonia
Congestive Heart Failure
Dystocia Radiographs are useful to detect:
Position of fetus Size of fetus Number of fetuses left Whether fetus is still alive
Dystocia
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
