SILVA, Helena M. et al. Intralobar sequestration: presenting in the first year of life. Nascer e Crescer [online]. 2012, vol.21, n.3, pp.138-141. ISSN 0872-0754.

Introduction: Pulmonary sequestration is a rare abnormal­ity characterized by an area of non-functioning abnormal lung tissue, which receives its blood supply from a systemic artery. It is divided into two subtypes: intralobar and extralobar sequestra­tion. Intralobar sequestrations are rarely diagnosed in infancy. Case report: We describe the case of a two-months old child presenting with congestive heart failure, whose investiga­tion revealed intralobar sequestration. Cardiac catheterization confirmed the presence of a vessel arising from the descending aorta to the inferior lobe of the left lung. He underwent surgical lobectomy of the left lower lobe and occlusion of the feeding ves­sel, with clinical resolution. Discussion/Conclusion: Intralobar pulmonary sequestration is an uncommon cause of heart failure in the infant. Diagnosis requires a high index of suspicion in order to prompt adequate treatment.

Keywords : Broncho-pulmonary malformation; congestive heart failure; intralobar sequestration; vascular disease.
