Added Value of Computed Tomography Angiography Prior to Bronchial Artery Embolization for Hemoptysis: A Retrospective Two-Center Study.

OBJECTIVES

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.

MATERIALS AND METHODS

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.

RESULTS

We included 31 patients in the QCTA group, and 35 in the control group. Clinical success was = 24/31 (77.4%) in the QCTA group and = 27/35 (77.1%) in the control group ( = 0.979). Technical success was = 37/42 (88.1%) in the QCTA group and = 39/42 (92.86%) in the control group ( = 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 ( = 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.

CONCLUSIONS

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.
