Abstract：
UNASSIGNED: The aim of this retrospective study was to evaluate the added value of pre-procedural computed tomography angiography (CTA) prior to bronchial artery embolization for patients presenting with hemoptysis.
UNASSIGNED: In this retrospective study, we evaluated patients admitted for hemoptysis from 2010 to 2021 and treated by catheter-directed embolization. After establishing quality criteria for pre-procedural computed tomography (CT), patients were divided into two groups depending on their pre-procedural imaging assessment: Quality CT-angiography (QCTA group) and suboptimal pre-procedural imaging (suboptimal CTA, unenhanced or no CT evaluation; control group). Groups were compared based on radiological success, procedure-related complications, and clinical success, including cessation of hemoptysis, recurrence rates, and overall mortality.
UNASSIGNED: We included 31 patients in the QCTA group, and 35 in the control group. Clinical success was n = 24/31 (77.4%) in the QCTA group and n = 27/35 (77.1%) in the control group (p = 0.979). Technical success was n = 37/42 (88.1%) in the QCTA group and n = 39/42 (92.86%) in the control group (p = 0.820). Overall recurrence was 10.6%. Minor complications occurred in 27.3%, and one major complication was reported.The concordance between the affected bleeding lung and the identification of pathological arteries during angiography was better in the QCTA group (p = 0.045).The average number of culprit arteries (bronchial, non-bronchial systemic arteries [NBSA] or pulmonary) in the QCTA group was not significantly higher than that in the control group.
UNASSIGNED: Preprocedural QCTA better identifies the affected bleeding lung and bleeding vessels compared to direct angiography. No difference in clinical success, complications, recurrence rates, or mortality was observed.

摘要：
■这项回顾性研究的目的是评估支气管动脉栓塞术前计算机断层扫描血管造影（CTA）对咯血患者的附加值。
■在这项回顾性研究中，我们评估了2010年至2021年因咯血入院并接受导管引导栓塞治疗的患者.建立术前计算机断层扫描（CT）的质量标准后，患者根据术前成像评估分为两组：优质CT血管造影（QCTA组）和次优术前成像（次优CTA，未增强或无CT评估；对照组）。根据放射学上的成功进行了比较，手术相关并发症,和临床成功，包括停止咯血，复发率,和总死亡率。
■我们纳入了QCTA组的31名患者，对照组为35。QCTA组的临床成功率为n=24/31（77.4％），对照组为n=27/35（77.1％）（p=0.979）。QCTA组的技术成功率为n=37/42（88.1％），对照组为n=39/42（92.86％）（p=0.820）。总复发率为10.6%。轻微并发症发生率为27.3%,报告了一个主要并发症。QCTA组受影响的出血肺与血管造影过程中病理动脉的识别之间的一致性更好（p=0.045）。罪犯动脉的平均数量(支气管，QCTA组的非支气管系统动脉[NBSA]或肺）未明显高于对照组。
■与直接血管造影相比，术前QCTA能更好地识别受影响的肺部出血和出血血管。临床成功没有区别，并发症,复发率,或观察到死亡率。
