Hypertrophied bronchial artery in cystic fibrosis diagnosed by computed tomography angiography

Preprocedural Planning with Prospectively Triggered Multidetector Row CT Angiography Prior to Bronchial Artery Embolization in Cystic Fibrosis Patients with Massive Hemoptysis

“…With advancements in CT imaging of the chest, thoracic radiology is a viable option in defining the bronchial circulation in patients with hemoptysis [6][7][8][9][10][11]. In a cohort of 46 patients in whom a 4-or 16-detector row was used, investigators found that multidetector row helical CT angiography of the thorax with three-dimensional images was superior to transverse CT scans in depicting the ectopic origin of the bronchial arteries.…”

“…Fiber-optic bronchoscopy has been used as a diagnostic tool to identify the site of bleeding, but the timing remains controversial [4,5]. However, there is growing evidence that multidetector row CT angiography of the chest is useful in identifying bleeding bronchial arteries [6][7][8][9][10][11]. Therefore, this study evaluated the usefulness of electrocardiographically synchronized, prospectively triggered multidetector row CT (ECG-MDR-CT) angiography of the aorta in depicting bronchial artery anatomy in adult CF patients with refractory massive hemoptysis in preparation for BAE.…”

“…These vessels may originate from various arteries, such as intercostal arteries, branches of the subclavian or axillary arteries or inferior phrenic arteries . Hypertrophied bronchial and nonbronchial systemic arteries can be observed with CT angiography . Although these vessels may be studied without exposure to ionizing radiation by using MRI with contrast agent injection, a method allowing the visualization of these vessels without requiring contrast agent injection may provide a valuable alternative.…”
