To retrospectively evaluate the depiction of bronchial and nonbronchial systemic arteries with dual-source computed tomography (DSCT) versus conventional angiography in patients with hemoptysis.
DSCT and conventional angiography of thorax were performed in 66 patients with hemoptysis. There were 46 males and 20 females with a mean age of 45 (22-72) years. Findings on DSCT, including CT scans, maximal intensity projections and three-dimensional volume-rendered images were used to evaluate the visibility and traceability of bronchial and/or nonbronchial systemic arteries. CT scans were evaluated by two radiologists in consensus. The CT findings were compared with those of conventional angiography.
A total of 171 (87 right, 84 left) bronchial arteries and 18 nonbronchial systemic arteries were visible on DSCT. The right bronchial arteries arose from intercostal-bronchial trunk thoracic aorta (n = 46), common trunk of both bronchial arteries (CBT) (n = 32) and thoracic aorta (n = 9) whereas left bronchial arteries arose from thoracic aorta (n = 50), CBT (n = 32) and left subclavian artery (n = 2). Compared with angiography, the accuracy of DSCT in the diagnosis of hemoptysis responsible vessels (i.e. dilatation BA) was approximately 88.7% (133/150). DSCT correctly diagnosed 18 nonbronchial systemic arteries, but missed 7; DSCT correctly diagnosed 5 bronchial-pulmonary vascular fistulas, but missed 15.
Excellent for evaluating hemoptysis, DSCT may identify the origin and ostial position of bronchial arteries, detect non-bronchial systemic arteries and act as a roadmap for percutaneous transcatheter embolisation.
回顾性评估双源计算机断层扫描（DSCT）与传统血管造影术对咯血患者支气管和非支气管体动脉的显示情况。
对66例咯血患者进行胸部DSCT和传统血管造影检查。其中男性46例，女性20例，平均年龄45岁（22 - 72岁）。DSCT的检查结果，包括CT扫描、最大密度投影和三维容积再现图像，用于评估支气管和/或非支气管体动脉的可视性和可追溯性。CT扫描由两位放射科医生共同评估。将CT检查结果与传统血管造影的结果进行比较。
DSCT上共可见171支（右侧87支，左侧84支）支气管动脉和18支非支气管体动脉。右侧支气管动脉起源于肋间 - 支气管干胸主动脉（n = 46）、双侧支气管动脉共同干（CBT）（n = 32）和胸主动脉（n = 9），而左侧支气管动脉起源于胸主动脉（n = 50）、CBT（n = 32）和左锁骨下动脉（n = 2）。与血管造影相比，DSCT对咯血责任血管（即扩张的支气管动脉）的诊断准确率约为88.7%（133/150）。DSCT正确诊断了18支非支气管体动脉，但漏诊了7支；DSCT正确诊断了5例支气管 - 肺血管瘘，但漏诊了15例。
DSCT在评估咯血方面表现出色，可确定支气管动脉的起源和开口位置，检测非支气管体动脉，并可作为经皮经导管栓塞术的路线图。
