随着超声图,CT等非损伤性检查的发展,肾动脉造影的指征日趋狭窄。但是,在没有CT和超声图的单位里,药物血管造影仍是泌尿放射学诊断的重要工具。注射肾上腺素使肾动脉收缩,能提高肿瘤血管的显示率。但是,在滴入剂量过大时,可引起肾末端动脉及肿瘤滋养动脉收缩而不能显示肿瘤血管,或使肾静脉不显影。因此,肾上腺素血管造影用于肾肿块患者,最适宜的剂量为2~5微克,注射肾上腺素与造影剂的间隔时间不应超过1分钟。动物实验发现血管紧张素对于肾血管的作用比肾上腺素更外周一些,从而推测血管紧张素引起肿瘤滋养动脉收缩的作用更弱。作者150余例的实践表
With the development of ultrasound images, CT and other non-invasive examination, indications of renal artery angiography increasingly narrow. However, in the absence of CT and ultrasound images of the unit, the drug angiography is still an important tool for urological diagnosis. Adrenaline injection of renal artery contraction, can increase the rate of tumor vascular display. However, overdosage may cause renal artery and tumor nourish the arteries to contract, failing to show tumor blood vessels, or renovating the renal veins. Therefore, adrenaline angiography for patients with renal masses, the most appropriate dose of 2 to 5 micrograms, injection of epinephrine and contrast agent interval should not exceed 1 minute. Animal experiments found that the role of angiotensin in renal blood vessels more peripheral than adrenaline, which speculated that angiotensin-induced tumor nourishing artery contraction effect weaker.
