Example 1. Male, 54 years old. No subjective symptoms, no history of hypertension. On physical examination, it was found that there was a 4cm x 5cm in the small bump on the umbilicus, smooth movement, no tenderness. Surgical treatment is planned. During the operation, the tumor is located in the lower part of the transverse colon and descending in the duodenum, and the posterior side is in adhesion with the abdominal aorta and the inferior vena cava. When puncturing the mass, the blood pressure jumped to 29.3/13.3 kPa. Pheochromocytoma was immediately suspected, and a vasopressor drug was prepared. Once again, the blood pressure surged again when the tumor was peeled off, and the operation was completed with phentolamine lowered blood pressure. After the removal of the mass, the blood pressure plunged to 8/6.akPa, which was changed to Aramin boost. After the blood pressure was maintained for 5 days, the blood pressure was relieved and the patient was discharged. Pathology report: pheochromocytoma.
