For pheochromocytoma, the usual tests include routine blood tests, routine urine tests, and biochemical examinations. Specific tests mainly involve collecting blood and urine catecholamine metabolites to help diagnose the condition. Furthermore, further localization diagnostics are conducted on the patient via abdominal ultrasound, as well as CT or MRI scans, to determine the specific location of the pheochromocytoma growth. Further examinations are conducted in preparation for subsequent surgery, with treatment generally recommended to be surgical. During treatment, antihypertensive drugs are used in conjunction to control blood pressure and maintain stability of the condition.

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.

What should I do if pheochromocytoma causes excessive sweating?

Patients with pheochromocytoma generally exhibit profuse sweating, which is a manifestation of sympathetic excitement. This occurs because the capillary beds throughout the body of a person with pheochromocytoma are constricted, including the sweat glands. Thus, it is easy to exhibit these symptoms of sympathetic excitement, characterized by nervousness, heavy sweating, and weight loss. So, how should this be treated? The key is to treat the cause. In the clinic, after collecting some blood history, conducting various blood tests, and performing adrenal CT scans among other imaging studies, a clear diagnosis of pheochromocytoma is made. Then, we will use some alpha receptor blockers, one to lower the blood pressure to a normal range and another to dilate the capillary beds throughout the body. After this, we proceed with the related surgical treatment. Following the surgical removal of the tumor, symptoms such as sweating will gradually be relieved.

What department does pheochromocytoma see?

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.

What should I do if a pheochromocytoma ruptures?

When a pheochromocytoma ruptures, it is advised that the patient immediately goes to the emergency department of the hospital for relevant examinations to confirm the diagnosis and to immediately control the blood pressure to a relatively stable and safe level. After a comprehensive evaluation, the urology department will perform emergency surgical removal to save the patient's life. Spontaneous rupture and bleeding of adrenal pheochromocytoma is quite rare. The possible reasons might be long-term hypertension leading to poor vascular function, or rapid tumor growth with high capsule pressure causing vascular rupture. Additionally, intense exercise, excessive fatigue, and transient increases in blood pressure could also be triggering factors.

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.
