摘　　要：目的:探讨肾上腺嗜铬细胞瘤的血管造影表现及并发症。方法:收集6例疑诊右侧肾上腺嗜铬细胞瘤病人行腹主动脉及选择性肾上腺动脉造影检查及数字电影摄影。结果:瘤体均由右肾上腺动脉供血。血管造影显示动脉期肿瘤血管增多、增粗、纡曲。2例见静脉早显。实质期染色浓密、不均匀。静脉期仍可见瘤体较长时间染色。2例出现高血压危象,经对症处理,血压趋于稳定。结论:肾上腺嗜铬细胞瘤由肾上腺动脉供血,其富血管性及延长显影的血管造影特点,有助于区别其它腹腔及腹膜后肿块。术中应密切监测血压,出现危象应及时处理。Objective:To study the angiographic manifestations and complications in patients with adrenal pheochromocytomas.Methods:The abdominal aortography,the selective angiography of suprarenal artery and digital cine photograph were performed in 6 patients with doubtful right adrenal pheochromocytomas.Results:The arterial blood supply of the tumors was derived from right adrenal artery.DSA features:There were numerous,coarse and tortuous vascularity on the arterial phase,and a few veins were seen in 2 cases.Capillary and venous phases revealed lasting heavy tumor stain.2 cases of hypertension crisis were recovered after appropriated management.Conclusion:The feeding arteries of pheochromocytomas are derived from adrenal arteries.DSA features including hypervascularity and lasting tumor stain in patients with pheochromocytomas are helpful to distinguish other abdominal masses.Blood pressure must be strict measured in the selective angiography and treat crisis at once.
