Pheochromocytoma originates from chromophobic tissues in the adrenal medulla, sympathetic ganglion or other sites. This tumor releases large amounts of catecholamines (epinephrine, norepinephrine, dopamine) continuously or intermittently, which can cause persistent or paroxysmal hypertension and multi-organ functional and metabolic disorders. The treatment of this disease is specifically as follows: 1. Drug therapy: It is difficult to control hypertension by applying drugs alone. Surgery is the treatment of choice after diagnosis, but alpha-blockers such as prazosin should be used to lower blood pressure before surgery. Sedatives can be applied if the headache is severe. 2.Surgical treatment: Most pheochromocytomas are benign and can be cured by surgical resection, which has certain risks. During anesthesia and surgery, hypertensive crisis, arrhythmia and shock can be induced. Blood pressure should be controlled with antihypertensive drugs in case of sudden rise in blood pressure. After resection, blood pressure drops suddenly and peripheral circulation is poor, so blood volume should be replenished and norepinephrine should be used for symptomatic treatment if necessary. 3. Treatment of malignant pheochromocytoma: Malignant pheochromocytoma is insensitive to chemotherapy and radiotherapy and is difficult to treat. Without extensive metastasis, it can be removed surgically, and those who cannot be removed can be treated with symptomatic drugs to control symptoms. 4.Treatment of complications: Complications mainly include hypertensive crisis, heart failure, kidney injury and hypertensive encephalopathy, etc., which should be treated symptomatically according to the situation. 6. Diet and life conditioning treatment: Absolute bed rest, avoid excessive anxiety, eat high-calorie, high-protein, high-vitamin, easy-to-digest food, avoid caffeinated beverages, and keep your body and mind happy during attacks. Most pheochromocytomas are benign and can be cured by early diagnosis and surgical removal. Malignant pheochromocytoma is more difficult to treat, and can be treated with surgery and symptomatic medication, with varying prognosis.
