Coil embolization to treat pulmonary sequestration in the right upper lobe

Pulmonary sequestration (PS) is a congenital lung malformation recognized by abnormal lung tissues separated from normal lung in embryonic development and fed by aberrant systematic arteries, which lack normal communication with bronchial trees. Although there have been a few case reports of pulmonary sequestration, it is primarily located in the lower lobe and left lung, rarely in the right upper lobe. Here, we report a case presented with haemoptysis. Computed tomography images revealed flake ground-glass shadows in the right upper lobe. Computed tomography angiography demonstrated an artery supplied the affected lesions stemmed from the aortic arch. We diagnosed and treated her with bronchial artery angiography with coil embolization. No complications were found after operation until now. Thus, CTA could help identify the abnormal blood vessels, and interventional therapy may be an effective alternative to surgery of pulmonary sequestration.
