Abstract
Systemic arterial supply to a segment of normal lung is rare.1 Usually the anomalous systemic artery arises from the descending aorta, although it can arise from other sites including the coeliac axis.1–3 Case reports documenting an anomalous artery to normal lung from the coeliac axis are few. However, in these cases the patients were being investigated for respiratory symptoms and all were under the age of 50. In our case, we describe a rare case of anomalous systemic arterial supply arising from the coeliac axis to the right lower lobe, in the absence of abnormal bronchial connection or parenchymal disease in an asymptomatic patient. The anomalous arterial supply was an incidental finding on CT. The literature suggests surgical treatment to prevent symptoms of haemoptysis or congestive cardiac failure, but it is unclear from current evidence whether this is indicated in an asymptomatic patient.
Highlights
It has been debated as to whether anomalous systemic artery supply to normal lung should fall within the "sequestration spectrum." There have been attempts to improve nomenclature, to better reflect the bronchial connection, arterial supply and venous drainage, the complexity of these abnormalities makes it difficult.[2]
The anomalous artery arises from the descending thoracic aorta, less frequently it may arise from the abdominal aorta or other vessels including the coeliac axis.[2,3]
We describe a case of an older—53-y ear-old— asymptomatic patient, with a normal chest radiograph and an incidental discovery of an anomalous systemic arterial supply from the coeliac axis to normal lung
Summary
An overlooked cause of haemoptysis and heart failure; anomalous systemic arterial supply to normal lung. Summary: Systemic arterial supply to a segment of normal lung is rare.[1] Usually the anomalous systemic artery arises from the descending aorta, it can arise from other sites including the coeliac axis.[1,2,3] Case reports documenting an anomalous artery to normal lung from the coeliac axis are few. In these cases the patients were being investigated for respiratory symptoms and all were under the age of 50.
