Role of computed tomography angiography in the evaluation of haemoptysis in children: Decoding the abnormal vessels.
Haemoptysis in children is potentially life-threatening. In most cases, the bleeding arises from the systemic circulation, and in 5-10 per cent of cases, it arises from the pulmonary circulation. The role of computed tomography angiography (CTA) in this setting is important. This study was undertaken (i) to study the role of single-phase split-bolus dual energy contrast-enhanced multidetector row CTA (DECTA) in the evaluation of haemoptysis in children; (ii) to analyze the patterns of abnormal vascular supply in the various aetiologies encountered. ⋯ Active infections and bronchiectasis are the most common causes of haemoptysis in children. While post-infectious sequelae are less common, in patients with haemoptysis, the presence of any abnormal arteries correlates with a more frequent diagnosis of bronchiectasis. NBSCs are more common in post-infectious sequelae and CHD.
