Abstract:
ObjectiveTo evaluate the priority application of thin adrenal CT scanning in out-patients with hypertension for early diagnosis of adrenal hypertension.MethodsThe patients with hypertension were collected from January to August 2009,in whom the secondary hypertension ( including endocrine and renal hypertension) and malignant cancers were excluded.All patients accepted the adrenal CT scan firstly,and then the patients with the positive result of morphological abnormalities in the adrenal CT( including adenoma and hyperplasia)were evaluated for endocrine function of adrenal glands.Results A total 362 cases of hypertension were studied,in.cluding 162 males and 200 females.The average age was (60.9 ±9.3 ) year-old,the average duration of hypertension was ( 13.8 ±5.3 ) year.After adrenal thin layer scanner CT scan,35 patients ( 9.6％ ) with adrenal abnormalities were found.Endocrine functional assessments of adrenal glands were carried out among these patients,17 cases (4.7％) with functional lesions were diagnosed,including 14 cases(3.9％ )with primary hyperaldosteronism,2 cases(0.6％ )with Cushing's syndrome,and 1 case ( 0.3％ ) with pheochromocytoma.Conclusion This study revealed that the percentage of adrenal lesions in outpatients with hypertension was 9.6％.The percentage of adrenal hypertension was 4.7％.Thin layer CT scan seems to effectively screen the adrenal hypertension with adrenal lesions,and would be helpful to the diagnosis of endocrine hypertension.
