Normal values for urinary vanilloic amygdalin are in the range of 2-6 mg/24 hours of urine. High urinary vanilloid amygdalin indicates the presence of pheochromocytoma and other diseases, which can cause a malignant increase in blood pressure, usually up to 160/110 mmHg or more, and the highest blood pressure can reach 240/140 mmHg, with the possibility of acute myocardial infarction, acute cerebral hemorrhage and acute cerebral infarction at any time. At this time, surgery should be performed to remove the adrenal adenoma in time to prevent the progressive increase of blood pressure that cannot be controlled, and drugs such as terazosin hydrochloride, uradil and phentolamine should be added to actively control blood pressure.
