目的采用MSCTA及后处理技术分析肺腺癌及肺鳞癌L1R1型支气管动脉开口直径差异,为提高插管成功率提供有价值的临床信息。方法收集45例肺腺癌L1R1型支气管动脉MSCT图像,68例肺鳞癌L1R1型支气管动脉图像,测量并比较肺腺癌及肺鳞癌L1R1型支气管动脉开口直径差异。结果肺腺癌L1R1型左右两侧支气管动脉开口直径,肺鳞癌L1R1型左右两侧支气管动脉开口直径差异均有统计意义(P均<0.05);肺腺癌与肺鳞癌L1R1型左侧支气管动脉、右侧支气管动脉开口直径比较均差异均无统计学意义(P均>0.05)。结论 MSCTA及后处理技术有助于了解肺腺癌L1R1型支气管动脉、肺鳞癌L1R1型左右两侧支气管动脉差异,为临床开展介入治疗,提供有价值的临床信息。
Objective To analyze the difference of the diameter of L1R1-type bronchial artery in patients with lung adenocarcinoma and lung squamous cell carcinoma by MSCTA and post-processing techniques, so as to provide valuable clinical information for improving the success rate of intubation. Methods 45 lung adenocarcinoma L1R1 bronchial artery MSCT images and 68 lung squamous cell carcinoma L1R1 bronchial artery images were collected. The differences in diameter of L1R1 bronchial artery between lung adenocarcinoma and lung squamous cell carcinoma were measured and compared. Results The diameter of bronchial artery of L1R1 type in lung adenocarcinoma and the diameter of bronchial artery in L1 and L2 squamous cell carcinomas were significantly different (all P <0.05) Arterial and right bronchial artery opening diameter were no significant difference (P> 0.05). Conclusion MSCTA and post-processing techniques can help to understand the difference of L1R1 bronchial artery and lung squamous cell carcinoma L1R1 bronchial artery, and provide valuable clinical information for clinical intervention.
