We present the case of an 81-year-old patient, who was transferred to our department for diagnostic work-up and treatment of hemoptysis of the right lung. Two-phase contrast-enhanced chest CT revealed filling defects in right upper lobe and middle lobe pulmonary artery during the pulmonary-artery phase who vanished in the subsequent aortographic phase, consistent with systemic-artery-to-pulmonary-artery fistulas (SA-PAFs) of right bronchial artery mimicking pulmonary embolism. Selective bronchial catheter-arteriography confirmed bronchial SA-PAFs and bronchial artery embolization was performed effectively and without complication. For the best of our knowledge, this is the first case of a bronchial systemic-artery-to-pulmonary-artery-fistula mimicking PE directly correlated and proved with bronchial artery angiography.
我们报告一例81岁患者，该患者因右肺咯血被转至我科进行诊断检查和治疗。胸部双期增强CT显示，在肺动脉期右上叶和中叶肺动脉有充盈缺损，而在随后的主动脉造影期消失，这与右支气管动脉的体循环动脉-肺动脉瘘（SA-PAFs）相符，类似肺栓塞。选择性支气管导管动脉造影证实了支气管SA-PAFs，并有效实施了支气管动脉栓塞术，且未出现并发症。据我们所知，这是首例通过支气管动脉造影直接关联并证实的类似肺栓塞的支气管体循环动脉-肺动脉瘘病例。
