Abstract
Aims: The objective of this study is to assess the cases of massive hemoptysis suited for bronchial artery embolization (BAE).
The useful role of computed tomography angiography (CTA) in assessing the arteries responsible for the hemoptysis, prior to endovascular imaging and intervention is assessed.
Materials and Methods: CTA was performed with a 16 slice multi-detector row computed tomography scanner on all cases of massive hemoptysis provisionally posted for BAE (12 cases) in a 9 month period.
Results: Out of the 12 patients, 10 were completely symptom free after 6 months (83% success rate). Out of the
12 cases, 1 was judged as suboptimal detection on the CTA as compared with the conventional angiography. In 11 cases, CTA
appropriately demonstrated the hypertrophied bronchials, which were confirmed on conventional angiography and subsequently embolized (sensitivity 92%). All the 11 cases, which demonstrated the bronchial arterial (BA) and non-bronchial arterial feeders were also detected on conventional angiography (specificity 92%).
Conclusions: CTA is helpful in identifying the precise origin of the BAs from the aorta, which enhances the success of the procedure and clinical results. We recommend CTA before conventional angiography and attempting BAE.
