title: Segmental aplasia of the caudal vena cava in a dog.
abstract: Ultrasonography, angiography, magnetic resonance imaging, and exploratory laparotomy of a 2-year-old wheaten terrier with lethargy, exercise intolerance, and ascites revealed segmental aplasia of the caudal vena cava with azygos continuation, complicated by thrombus formation. Surgeries were performed on the blind-ended vessel to remove thrombi, enhancing shunting of blood through the azygos vein.
