1) Objective To elevate the perioperative security of pheochromocytoma cases.

2) Pheochromocytoma is an important cause of secondary hypertension, whose pathogenesis is yet to be clarified. It is still difficult to identify malignant cases at early stage.

3) Objective To investigate diagnosis and treatment of pheochromocytoma of bladder.

4) Incidence of malignancy was greater in ectopic pheochromocytoma as compared with pheochromocytoma of adrenal medulla.

5) Methods: A retrospective study on 43 cases of pheochromocytoma and treated in 1983 ~2000 was made.

6) In conclusion, an ACTH-secreting pheochromocytoma is rarely seen clinically and seldom reported in the literature. We successfully treated this patient with left adrenalectomy.

7) Conditions with the lowest incidence were adrenocortical carcinoma, pheochromocytoma, and pituitary adenomas.

8) Objetive To analyze the clinical features of extra-adrenal pheochromocytoma , evaluate the factors associate with intraoperative blood pressure fluctuation.

9) For the mutiple masses of extra-adrenal pheochromocytoma, the middle abdominal incision may be the choice.

10) Prazosin was used in 18 cases of pheochromocytoma (PHEO) preoperatively, the drug made the operation successful and had no significant side effect.

11) Nine cases of adrenal pheochromocytoma ( AP ) were confirmed by surgery and pathology.

12) If pheochromocytoma occurs,(http:///pheochromocytoma.html) it is usually bilateral an anterior abdominal approach is preferred for the operation.

13) Despite being a rare tumor, pheochromocytoma still raised great concerns among physicians and surgeons because it can cause curable secondary hypertension.

14) Pheochromocytoma is a neoplasm of neural crest origin arising in the adrenal medulla.

15) Objective : To evaluate the diagnostic value of MRI and DSA in the large adrenal pheochromocytoma.

16) Palliative therapy involving cyclophosphamide, vincristine and dacarbazine have been conducted for malignant pheochromocytoma. 131I-MIBG and 123I-MIBG may also be used.

17) Result : Hemodynamic insufflation and tumor manipulation in the laparoscopic excision of pheochromocytoma.

18) Objective To measure urinary catecholamines and VMA by HPLC-ECD for diagnosis of pheochromocytoma.

19) Abstract: Purpose : To evaluate the surgical method of pheochromocytoma.

20) Objective : To explore the diagnosis and treatment of extra - adrenal pheochromocytoma.

21) The pathologic study confirm that 8 cases were primary aldosteronism, 2 cases adrenocortical adenoma, 2 cases pheochromocytoma.

22) Methods The clinical data of 4 cases of coexisting primary aldosteronism and pheochromocytoma were retrospectively analyzed.

23) This staining, particularly for chromogranin A, may be useful in distinguishing pheochromocytoma from adrenal cortical carcinoma.

24) Methods A ground based research was(undertaken) using a clinostat to simulate microgravity, and rat pheochromocytoma(PC12) cells used as neuronal cell model.
