For patients with pheochromocytoma, comprehensive examinations are necessary for diagnosis. For instance, measuring catecholamines and their metabolites in blood or urine can help determine if there is a noticeable increase in catecholamine levels. Furthermore, adrenal CT scans can be used to assess the condition, where in many cases, significant occupying lesions can be detected through adrenal CT scans. In addition, other related tests also hold diagnostic value and significance, such as magnetic resonance imaging, ultrasound, and related nuclear scanning tests, which can assist in qualitative and locational diagnosis.

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.

Can malignant pheochromocytoma be cured?

When pheochromocytoma becomes malignant, it can be cured through clinical approaches, although malignant pheochromocytoma mainly refers to those that have distant metastases. It primarily exhibits aggressive growth or is accompanied by metastases to other organs, and surgery cannot completely remove it, leading to a high recurrence rate post-surgery. Generally, the five-year survival rate for patients with malignant pheochromocytoma does not exceed half. If treated with chemotherapy or arterial embolization, it can control the patient's blood pressure and alleviate the tumor burden, thereby extending the survival period. In summary, the treatment of malignant pheochromocytoma is relatively challenging, has a high recurrence rate, and poses a significant threat to human life.

What department should I go to for pheochromocytoma?

Pheochromocytoma generally requires consultation at the endocrinology or surgical department. Please ask a physician to assess the current situation. For further examination and diagnosis of pheochromocytoma, qualitative and locational diagnostics are necessary. Qualitative diagnostics typically involve blood tests where levels of catecholamine metabolites in the blood and urine are tested to assist in diagnosis; locational diagnostics involve using CT scans, MRI, and ultrasound to help determine the specific location of the tumor. Treatment for pheochromocytoma generally involves surgical removal of the tumor once it is found, combined with medication treatment, which often leads to satisfactory therapeutic outcomes.

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.
