Primary splenic torsion in a Boston terrier

Area of Science:

• Veterinary Medicine
• Canine Surgery
• Diagnostic Imaging

Background:

• Splenic torsion is a rare but life-threatening condition in dogs, characterized by twisting of the spleen on its vascular pedicle.
• Clinical signs can include anemia, hemoglobinuria, abdominal pain, and splenomegaly, often leading to shock if untreated.
• Early diagnosis and surgical intervention are crucial for a positive prognosis.

Purpose of the Study:

• To report the first case of splenic torsion in a Boston terrier.
• To evaluate the diagnostic utility of ultrasonography and computed tomography (CT) in identifying splenic torsion.
• To describe the successful surgical management of splenic torsion in this breed.

Main Methods:

• A 7-year-old female Boston terrier presented with acute signs of anemia and hemoglobinuria.
• Abdominal radiography and ultrasonography were performed, revealing splenomegaly and characteristic signs of splenic torsion.
• Computed tomography (CT) further delineated the splenic anatomy, showing a C-shaped spleen.
• Exploratory laparotomy confirmed the diagnosis, followed by splenectomy.

Main Results:

• Diagnostic imaging, including ultrasonography and CT, accurately identified splenic torsion.
• The spleen exhibited a C-shaped morphology on imaging, consistent with torsion.
• The dog underwent successful splenectomy and recovered without complications.

Conclusions:

• Splenic torsion should be considered in dogs presenting with acute anemia and hemoglobinuria, even in breeds not typically associated with the condition.
• Ultrasonography and CT are valuable tools for the diagnosis of splenic torsion, providing detailed anatomical information.
• Splenectomy is an effective treatment for splenic torsion, leading to favorable outcomes in canine patients.
