Plain-English summary
Two dogs were found to have tumors on their right adrenal glands, which are located near a rare condition called segmental caudal vena cava aplasia, where part of a major blood vessel is missing. During surgery, the veterinarians discovered that the tumors were tightly connected to the blood vessel, making removal more complicated. They successfully removed the tumors along with part of the blood vessel. This type of surgery is necessary for dogs with this condition, even if the tumor hasn't invaded the blood vessel itself.

Abstract
Segmental caudal vena cava (CVC) aplasia is a rare congenital vascular anomaly in dogs. Two dogs were diagnosed by CT imaging to have right adrenal tumors with concomitant segmental CVC aplasia. During surgery, a firm connection between the right adrenal gland and CVC was observed in both cases. The adrenal glands were found ventral to the CVC and the adrenal tumor was resected including the vascular wall. CVC venectomy for tumor removal will be required if the right adrenal gland is displaced in dogs with segmental CVC aplasia, even if there is no intravascular invasion.
