Clinical manifestation of canine coronavirus enteritis and intestinal intussusception as its complication

Canine Coronavirus (CCV) is an important pathogen of dogs within the scope of canine enteritis complex, especially in puppies and young dogs, which may result in intestinal position changes such as invagination and/or intussusception. In this report, a 3-month-old male mixed breed dog with non-specific complaints such as loss of appetite, vomiting, hemorrhagic diarrhea, and suspected intestinal intussusception as a result of abdominal palpation was presented. Clinical examinations included physical, laboratory, radiographic, and ultrasonographic examinations. As a result of laboratory and ultrasonographic examinations, metabolic acidosis, hyperlactatemia, severe hypochloremia, anemia, and ileocecocolic intussusception were determined. Also, rapid diagnostic test results were negative for Canine Parvovirus (CPV) and Giardia but positive for CCV. In order to confirm the diagnosis of ileocecocolic intussusception, an exploratory laparotomy was performed. After the preparation and appropriate disinfection and sterilization procedures of the abdominal region, jejunocolic entero-anastomosis was performed as a surgical intervention. The dog was re-evaluated after 12 hours of hospitalization period after the operation. It was determined that vital and blood parameters were within reference ranges. As a result, it was concluded that clinicians should be vigilant of possible CCV infections where CPV has been ruled out and life-threatening conditions such as intestinal intussusceptions can occur as a result of CCV infection.
