Abstract：Objective: To investigate the clinical value of adrenal venous sampling（AVS） in the qualitative and localized diagnosis of pheochromocytoma. Methods: The clinical data of four patients diagnosed with pheochromocytoma and underwent AVS at the First Affiliated Hospital of Guangxi Medical University from October 2020 to September 2021 were preoperatively analyzed. Results: CT of the adrenal glands suggested three cases of left adrenal tumors and one case of bilateral adrenal tumors. Blood catecholamines were mildly elevated in three cases and significantly elevated in one case in combination with elevated cortisol-related hormones. The results of AVS suggested all four cases were pheochromocytoma, one of which was combined with cortisolism; the dominant side of the adrenal tumor was on the left in three cases and on the right in one case. All four patients underwent laparoscopic adrenal tumor resection （transperitoneal in three cases and retroperitoneal in one case）, and the postoperative pathology was pheochromocytoma in all four cases, with one case involving the entire adrenal cortex. Conclusion: AVS can be a useful adjunct to the qualitative and localized diagnosis of pheochromocytoma.
