目的 探讨螺旋CT血管成像在肺 癌肺叶切除治疗中的应用价值。方法 回 顾性分析2013年7月-2015年11月经我院治 疗的41例肺癌患者的肺叶螺旋CT血管成像 资料及临床资料病例。结果 螺旋CT血管 成像观察肺部腔内癌变肿块和管壁变薄或 者管腔狭窄等形态改变特征，并结合肺上 动脉减少、变细和与肿块相关，诊断41例 肺癌患者，结果显示2例处在0期；10例患 者处在I期，包括IA期3例，IB期7例；17 例患者处在II期，其中10例IIA期，7例 IIB期；12例患者处在Ⅲ期，包括5例ⅢA 和6例ⅢB。结论 螺旋CT血管成像能有效 帮助诊断肺癌癌变位置、大小和范围以及 肿块和血管、支气管直接关系，为肺癌患 者实施肺叶切除治疗的供了非常丰富的信 息资料，为手术成功提供了可靠的技术保 证。

Objective To investigate the application value of spiral CT angiography in the treatment of lung cancer lobectomy. Methods A retrospective analysis of 41 lung cancer patients' spiral CT angiography data and clinical data from July 2013 to November 2015. Results Spiral CT angiography to observe pulmonary cavity cancerous lumps and wall thinning or morphological change characteristics of luminal stenosis, and pulmonary artery reduce, thinner, and is associated with tumor, 41 patients with lung cancer diagnosis results show that the 2 cases were in stage 0. Ten patients in stage I, including the IA stage 3 cases, the IB 7 cases, 17 patients in stage II, including 10 cases of type IIA, 7 cases of stage IIB, 12 patients in Ⅲ period, including 5 cases Ⅲ A and 6 cases of Ⅲ B. Conclusion Spiral CT angiography can effectively diagnose the location, size and scope of lung cancer, as well as the direct relation of tumor, vascular and bronchus, which provides abundant information for patients to conduct lobectomy and provides a reliable guarantee for the success of operations.
