目的:探讨孤立性肾细胞癌在多层螺旋CT肾脏皮质早期扫描及血管成像技术在术前评估中的应用价值。方法:回顾性分析我院经手术及病理证实孤立性肾癌5例的术前多层螺旋CT影像数据,显示肿瘤和邻近肾内动脉分支的关系、肿瘤血管、肾动脉有无变异和其他病变以及肾静脉等。结果:5例孤立性肾癌中5例病灶均在皮质早期呈明显强化,实质期强化程度迅速下降;5例均见邻近动脉分支的受侵受压改变;1例见确切的一支或多支粗大的供血动脉及瘤体内肿瘤血管影;2例患肾出现静脉旱显;2例肾有副肾动脉;无一例患肾动脉狭窄。结论:MSCT血管成像技术的应用,不仅有助于孤立性肾癌的定性诊断,更有利于孤立性肾癌的术前治疗方案的评估。
Objective: To investigate the value of early diagnosis of solitary renal cell carcinoma (SCC) in renal cortex of MSCT with preoperative evaluation of angiography. Methods: The data of preoperative multislice spiral CT in 5 cases of solitary renal cell carcinoma confirmed by operation and pathology in our hospital were retrospectively analyzed. The relationship between the tumor and adjacent renal artery branches, the presence or absence of tumor blood vessels and renal arteries and other lesions And renal vein and so on. Results: In 5 cases of solitary renal cell carcinoma, all the 5 lesions showed obvious enhancement in the early stage of cortical and rapidly decreased in the parenchymal phase. The invasion and compression of adjacent artery branches were all changed in 5 cases and the exact one or more cases in 1 case Large blood vessels in the artery and the tumor tumor vessels in the tumor; 2 cases of renal vein appeared dry significantly; 2 cases of renal renal artery; no case of renal artery stenosis. Conclusion: The application of MSCT angiography is not only helpful for the qualitative diagnosis of solitary renal cell carcinoma, but also for the evaluation of preoperative treatment of solitary renal cell carcinoma.
