Title: Tumor vascularity and its supplied artery in pulmonary carcinoma: CT angiography versus digital subtraction angiography
Abstract: Objective To assess sensitivity and correlation of CT angiography (CTA) versus digital subtraction angiography (DSA) in detecting tumor vascularity and its supplied artery in pulmonary carcinoma (PLC). Methods Ninety-three patients with PLC underwent 219 vascular interventional therapies. The common and enhancement scan technique including CTA of high-speed helical CT was adopted before every treatment. The superiority arteries of PLC were observed through thoracic aortiography. Meanwhile, the corresponding pulmonary arterial angiography was held on according to tumor in lung segment. Microcatheter-inserted was used for further tumor angiography from superiority arteries. Statistics analysis was undertaken by SPSS 12.0 software. Results The coincidence of tumor vascularity and steins was 94.56% CTA and image-reconstructed versus DSA angiography. The focus with obvious evidences of tumor vascularity and stein had 13 with any evidence in DSA angiography. Conversely, the focus with obvious in DSA angiography had 15 with any evidences in CT image. Sensitivity comparison of two methods showed no statistics significances (P0.05). But for the bronchial artery-pulmonary veins fistula (APVS) and bronchial artery-pulmonary artery fistula (APAS), CT did not detected any evidence about it. Conclusion The supplied-arterial and vascularity of PLC can be evaluated effectively by common CTA, which is very helpful to making interventional therapy regime, and effective to avoid missing blood vessel during interventional management probably leading the treatment effect decrease. The detection coincidences of APVS and APAS in CTA and image-reconstructed is much lower than that in DSA angiography.
