Plain-English summary
A 4.5-month-old female Doberman was brought to the vet because she was very tired, drinking a lot, and had ongoing stomach issues. An ultrasound showed problems with a major vein in her abdomen, including swelling and a blood clot. Unfortunately, the vet determined that she had a serious congenital issue with her blood vessels, which led to her condition. Sadly, the decision was made to humanely euthanize her due to the severity of her health problems.

Abstract
A 4.5-month-old female intact Doberman was referred for acute on chronic gastrointestinal signs and acute lethargy, polyuria, and polydipsia. Abdominal ultrasonography revealed marked focal dilatation, thrombosis, and suspect phlebitis of the caudal vena cava (CVC; renal segment). The prehepatic CVC was not identified; however, an enlarged azygos vein was identified as cranial to the dilated vessel. The patient was humanely euthanized, and a necropsy confirmed congenital segmental aplasia of the prehepatic CVC with azygos continuation complicated by thrombophlebitis. While this vascular malformation has been documented in canines, this is the first reported case of concurrent thrombophlebitis.
