目的探讨CTA和DSA评价支气管肺癌的肿瘤血管的敏感性和相关性。方法分析93例支气管肺癌CTA及DSA图像。所有临床数据输入SPSS12.0统计分析。结果CTA与DSA检出肿瘤血管和肿瘤染色一致者87例,符合率为94.56%;CTA明显而DSA不明显者13例;DSA明显而CTAA不明显者15例;二者敏感性无明显差异,但CT未检出支气管肺动/静脉瘘。结论CTA能很好地评价肺癌供血动脉和内部血管、肿瘤染色,作为无创手段可在治疗前提供明确帮助,并避免在介入治疗中遗漏血管;但对支气管肺动/静脉瘘检出率有困难。
Objective To investigate the sensitivity and correlation of CTA and DSA in the evaluation of tumor vessels in bronchial carcinoma. Methods 93 CTA and DSA images of bronchogenic carcinoma were analyzed. All clinical data were entered into SPSS12.0 statistical analysis. Results The CTA and DSA showed the same staining of tumor vessels and tumors in 87 cases, the coincidence rate was 94.56%; 13 cases with obvious CTA but not obvious DSA; 15 cases with obvious DSA and not obvious CTAA; CT was not detected bronchial pulmonary artery / vein fistula. Conclusions CTA can evaluate pulmonary artery and internal blood vessels and tumor staining well, as a noninvasive means to provide definite help before treatment, and avoid the missed vessels in interventional therapy. However, the detection rate of bronchogenic pulmonary arteriovenous fistula is difficult .
