64排螺旋CT支气管动脉成像对咯血的诊断意义

Diagnostic significance of bronchial artery imaging by 64-slice spiral CT for hemoptysis

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 discuss the diagnostic value of bronchial and non-bronchial artery system by 64-slice CT bronchial artety imaging in patients with hemoptysis as the main symptom of lung disease .Methods 64-slice CT bronchial artery imaging was performed in 28 patients with hemoptysis .The resulting CT images were analysed to identify position of the bronchial and non-bronchial systemic artery .Results Bronchial arteries were shown in the CT images as follows, 43 bronchial arteries were identified on the right side and 46 on the left side; normal origin of bronchial artery accounted for 46%of the total .Twenty-three arteries of all the arter-ies originated in the non-bronchial arterial system were located on the right , and 41 on the left side .Conclusion 64-slice CT bronchial artety imaging can not only determine the location of the bronchial and non-bronchial systemic artery , but also confirm the reason of the disease with hemoptysis as the main symptom .Then, it may lay the foundation for further clinical treatment .
