STARD-compliant article: Comparison of pulmonary sequestrations with thoracic and abdominal aortic arterial supply

Abstract

Pulmonary sequestrations (PS) are typically supplied by a vessel originating from thoracic aorta, or abdominal aorta. Differences in imaging features between these PS subtypes have not been described. To analyze the imaging features of PS with arterial supply from the thoracic and abdominal aorta. Retrospectively, 23 pathologically proven cases of pulmonary sequestration were analyzed and compared based on the site of feeding artery origin. In 21 cases (21/23), the PS was soft tissue density. 1(1/23) PS was purely cystic and another heterogeneous with both cystic and solid components (1/23). In 16/23 cases, the feeding vessel(s) arose from the thoracic aorta (male:female ratio 1:7) and in 7/23 cases from the abdominal aorta (male:female ratio 4:3). Feeding vessels from the thoracic aorta were duplicated in 7/16 cases. PS location (P
