【摘要】 目的:评价血管造影尤其药物血管造影对小肾癌的诊断和鉴别诊断价值。材料与方法:26例直径3cm 以下肾脏小肿物血管造影前均进行了二维超声和 CT 平扫与增强检查。先行腹主动脉和肾动脉的标准血管造影,然后根据动脉造影表现确定是否再行药物性血管造影。后者是指先经肾动脉注入肾上腺素10μg,10～20秒后再行肾动脉造影。并对 CT、超声和血管造影的诊断结果做了统计分析与对比。结果:26例肾脏病变最后确定依断小肾癌14例,良性病性变12例。血管造影对该组小肾癌诊断检出率、特异性及符合率分别为:92.9%、91.7%、和92.3%;CT 为85.7%、16.7%和53.8%;超声为64.3%、33.3%和50.0%。血管造影与CT 和超声的特异性之间存在显著性差异。结论:血管造影尤其是药物血管造影对小肾癌的诊断和鉴别诊断具有重要价值。更多还原

【Abstract】 Objective:The purpose of this study was to evaluate angiography,especially the pharmacoangiography with epinephrine in the diagnosis of small renal carcinoma,on the basis of the results and its comparison with CT and sonography in 26 patients.Materials and Methods: 26 patients with small renal masses(diametre≤3cm)underwent sonographie and CT examination before performing angiographies The procedure of angiography should have aortography and con- ventional renal artery angiography performed previously to see if pharmacoangiography was needed. Pharmacoangiography consisted of the injection of 10μg epinephrine into renal artory,10～20 seconds before angiography.The patterns of neoplastic vasculotupe and tumor blush,and con- striction of neoplastic vessels after epinephrine injection were observed in order to make the diag- nosis.The results were statistically analyzed and compared with CT and sonographic changes. Results:The final diagnosis of 26 patients included 14 of small renal carcinoma and 12 of benign lesions.The sensitivity,specificity and accuracy of the three modaloties were:92.9%,91.7% and 92.3% in angiograme,85.7%,16.7% and 53.8% in CT scans and 64.3%,33.3% and 50.0% in sonogrames respectively.The specificity revealed statistical defferences between an- giogrames and CT scans or sonogram.Conclusion:Angiography,especially pharmacoangiography can be of great value in the diagnosis of small renal carcinoma.更多还原
