目的探讨支气管和非支气管动脉系统的64排CT支气管动脉成像对以咯血为主要症状的肺部疾病的诊断价值。方法对28例咯血患者进行64排CT支气管动脉成像。分析所得的CT图像以确定支气管和非支气管系统的动脉的位置。结果 CT可见支气管动脉情况为右侧43支,左侧46支;正常起源的支气管动脉占总数的46%;起源于非支气管动脉系统的动脉中有23支位于右侧,41支位于左侧。结论 64排CT支气管动脉成像不仅可以确定支气管动脉及非支气管动脉系统的血管位置,还可以明确以咯血为主要症状的疾病的病因,为临床进一步治疗奠定基础。
Objective To investigate the diagnostic value of 64-slice CT bronchial artery imaging of bronchial and non-bronchial arterial systems in pulmonary diseases with hemoptysis as the main symptom. Methods 64 cases of CT bronchial artery imaging were performed on 28 patients with hemoptysis. The resulting CT images were analyzed to determine the location of the arteries in bronchial and non-bronchial systems. Results CT showed bronchial artery in 43 cases on the right side and 46 on the left side. Bronchial arteries originated from the normal origin accounted for 46% of the total. Among the non-bronchial arteries, 23 were located on the right side and 41 on the left side. Conclusion 64-slice CT bronchial artery imaging can not only determine the vascular position of the bronchial artery and non-bronchial arterial system, but also clarify the etiology of the disease with hemoptysis as the main symptom and lay the foundation for further clinical treatment.
