|aberrant systemic artery arising from the celiac trunk|
|normal bronchial supply|
Isolated systemic arterial supply to normal lung (ISSNL) is included in the “sequestration spectrum” as originally proposed by Sade et al. According to the original classification of pulmonary sequestration by Pryce et al, this abnormality is classified as Pryce type 1. In type 2, the systemic artery supplies both normal and abnormal lung, having no communication with the tracheobronchial tree. In type 3, only noncommunicating abnormal lung receives the aberrant systemic artery.
