嗜铬细胞瘤(pheochromocytoma,简称Pheo)为起源于肾上腺髓质或肾上腺外嗜铬组织的肿瘤。肿瘤组织阵发性或持续性分泌过多去甲肾上腺素(norepinephrine,NE)和肾上腺素(epinephrine,E)产生一系列临床表现。近年来,由于诊断方法的改进,提高了诊断的准确率。诊断一旦确立,应立即给予药物治疗作术前准备。约90%患者可通过手术治愈,10%因属恶性肿瘤、转移或合并其它严重情况而不能手术者,则应持续药物治疗。自术前常规应用肾上腺素能阻滞剂以来,手术死亡率显
Pheochromocytoma (Pheo) is a tumor that originates from adrenal medullary or extrachromosomal chromaffin tissue. Paroxysmal or persistent hypersecretion of tumor tissue norepinephrine (NE) and epinephrine (E) produce a series of clinical manifestations. In recent years, due to the improvement of diagnostic methods, improve the diagnostic accuracy. Once diagnosed, medical treatment should be immediately given for preoperative preparation. About 90% of patients can be surgically cured, 10% of malignant tumors, metastases or other serious cases of inoperable, should continue the drug treatment. Since preoperative routine use of adrenergic blockers, operative mortality was significant
