Pheochromocytomas generally require a visit to urology for treatment. Initially, they mostly present with symptoms of hypertension, leading many to first visit cardiology. After differential diagnoses have ruled out other causes and confirmed pheochromocytoma, patients must then seek treatment from urology. Pheochromocytomas are generally located in the adrenal glands, hence they require surgical removal by a urologist. It is crucial to strictly control blood pressure during surgery, as fluctuations can be severe and significantly impact the patient's physical and mental health. Therefore, if a pheochromocytoma is detected, it is critical to seek timely medical treatment for a relatively better prognosis.

Causes of hypotension in pheochromocytoma

For cases of hypotension occurring in pheochromocytoma, it is most commonly seen after the surgical removal of the tumor. At this point, the concentration of catecholamines in the blood may significantly decrease, leading to a marked reduction in effective circulating blood volume, and thus causing hypotension. This situation is relatively common after surgery for pheochromocytoma. Usually, after surgical treatment and removal of the tumor, it is important to promptly discontinue the use of receptor blockers in patients and to appropriately replenish blood volume to effectively maintain central venous pressure. This approach can generally counteract the reduction in catecholamine levels caused by surgery, which leads to hypotension.

The manifestations of pheochromocytoma crisis

For patients with pheochromocytoma, during a crisis, it generally manifests as a sudden increase in the patient's blood pressure, which can rise to above 200-300 mmHg. Additionally, the patient experiences severe headaches and dizziness, severe nausea and vomiting. Some patients may experience significant discomfort and tachycardia, arrhythmias. Some patients also suffer from abdominal or chest pain, labored breathing, and difficulty breathing, and even blurred vision. In severe cases, the excessively high blood pressure can lead to hypertensive cerebral hemorrhage or other unexpected cardiovascular and cerebrovascular diseases. The patient’s vital signs are extremely unstable, often accompanied by multiple organ dysfunction or failure.

Which department should I go to for pheochromocytoma?

When pheochromocytoma occurs, it is generally recommended to visit the endocrinology department of a local hospital. Pheochromocytoma refers to tumors originating from the neuroectoderm, specifically chromaffin tissue. These tumors usually secrete catecholamines and can be classified into various types based on their origin. Patients typically exhibit a pronounced hypermetabolic state, such as malignant hypertension or hyperglycemia, and some suffer significant damage to the heart, kidneys, liver, and brain tissue due to malignant hypertension. For instance, this can lead to heart failure or hypertensive cerebral hemorrhage, severely threatening the patient's life. Treatment typically involves surgical intervention.

How is pheochromocytoma treated?

Currently, for the treatment of pheochromocytoma, it is primarily important that once diagnosed with pheochromocytoma, one should promptly visit the local hospital to arrange surgical treatment as soon as possible. By surgically removing the pheochromocytoma, this prevents the excessive secretion of catecholamines, which can lead to a hypertensive crisis in patients. Therefore, clinically, after diagnosing and locating the pheochromocytoma, receiving surgical treatment can often achieve satisfactory therapeutic outcomes. Typically, appropriate preparations must be made before surgery. Generally, prior to the operation, it is crucial to actively administer medications such as alpha-adrenergic blockers, beta-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, and catecholamine synthesis inhibitors to effectively treat and stabilize blood pressure.

Can a pheochromocytoma be treated without surgery?

For pheochromocytoma, it is still best to receive surgical treatment. Conservative treatment through medication alone has limited effects. In most cases, gradually increasing blood pressure leads to serious symptoms or signs in the patient, such as palpitations, shortness of breath, labored breathing, chest pain, accompanied by profuse sweating, and even severe panic and feelings of impending doom, posing serious life-threatening risks to the patient. In terms of treatment, it is advised to prioritize surgical removal of the tumor, as this can fundamentally lead to a complete cure. Additionally, appropriate medication can be used before and after the surgery to assist in treatment.
