ABSTRACT
Pulmonary sequestrations make up 10-30% of the cystic bronchopulmonary foregut malformations.29,32 They are classified by whether the sequestration resides within the visceral pleura of the normal lung (intralobar sequestration) or is invested by its own visceral pleura (extralobar sequestration). In both types of pulmonary sequestration however, there is no bronchial communication between the sequestrum and the normal tracheobronchial tree. In addition, the malformation receives its blood supply from aberrant systemic arterial vessels (Table 30.2).
