【摘要】 目的 定性和定量研究肺癌组织支气管动脉树的分布。 方法 对54例肺癌支气管动脉造影资料进行分析，并利用计算机图像处理系统进行肿瘤内支气管动脉的相对分布面积和相对平均灰度进行研究。 结果 肺癌表现为血管结构异常和肿瘤血管染色，其肿瘤血管染色范围/肿瘤面积，大于60%为多血供，9例(16.67%);30%～60%之间为中血供，37例(68.52%);小于30%为少血供，8例(14.81%)。肺癌支气管动脉树有10种X线征象可供参考。两肺不同部位的肿瘤供血动脉支进入肿瘤有相对恒定的门，可用时针表示其位置。 结论 支气管动脉在原发性肺癌组织的供血范围局限，应考虑肺动脉参与肿瘤供血和介入治疗。此外应重视肿瘤血管门的临床意义。
