A urinalysis is probably one of easiest and most important initial studies in the evaluation of a dog suspected of having Cushing s disease. Although this list seems large, all the blood needed is about 3 cc s or about half a teaspoon. Radiographs and ultrasounds might be run to see whether the dog has a tumor. A variety of other tests can be run as well that can aid in the diagnosis of Cushing s disease. If the dog has naturally occurring Hyperadrenocortism due to a tumor on the pituitary or adrenal glands then it can be surgically removed.
Prognosis is good especially if it is caught early and the tumor hasn t metastasized.
The main advantage of going through ventral midline is that all the abdominal contents, especially the liver, can be observed for metastasis of the tumor. The main disadvantage is the incision is on an area that has a lot of weight bearing on it and since Cushing s disease causes thin skin, bruising, and slow healing, this can cause problems in healing. Another disadvantage is the vet must go through a lot of fat to reach the adrenal glands because of the redistribution of fat to the abdominal cavity. The advantages of going through the side is all that fat can be avoided and the incision will not have all the pressure from the abdominal contents. The disadvantage of this type of surgery is only one adrenal gland can be seen at a time and looking for metastasis of the tumor is more difficult.
