However, this drug may also have serious side effects, so the veterinarian may choose to keep your dog under observation for the first 24 hours. The surgery to remove the adrenal gland is complex and has many possible complications, such as severe spikes in blood pressure and pulmonary embolism. If it cannot be removed with surgery because of other illness or age, medications such as Lysodren can be used.
Some of these are pulmonary edema, heart attack, cerebral hemorrhage, extreme increase in blood pressure, and heart failure. Treatment for pheochromocytomas includes removal of the adrenal gland and nearby lymph nodes. Since pheochromocytomas usually occur with other medical disorders, the veterinarian will want to treat the one that is the most serious first. Just like many other cancers, pheochromocytoma is most common in older dogs, and the average age of those with pheochromocytoma is about 10 years old. These hormones cause symptoms that are like those that happen when your dog is stressed, only these can happen at any time, no matter whether your dog is stressed or not. Pheochromocytoma can cause an increase of hormones, which include epinephrine, aldosterone, and cortisol.
The cause of pheochromocytoma is not known yet, although some veterinary medical professionals believe that exposure to toxins or other chemicals may be a contributing factor.Īdrenal gland cancer (pheochromocytoma), which are endocrine tumors that come from the chromaffin (neuroendocrine) cells in the adrenal gland, are not common in dogs. This happens due to the fact that the adrenal gland has a direct route through lymph nodes for distributing hormones, and cancer cells are able to be distributed right along with them. What makes this type of cancer even more dangerous is the rate of speed with which it spreads to other organs. The cortex has several layers that create and distribute three chemicals, androgens, glucocorticoids, and mineralocorticoids (aldosterone). Your dog’s adrenal gland has two unique areas, which are the inner medulla and the outer cortex.
