RESUMO
IntroduĆ§Ć£o: O sequestro pulmonar Ć© uma malformaĆ§Ć£o
rara caracterizada por uma massa de tecido pulmonar nĆ£o funcionante
que recebe irrigaĆ§Ć£o arterial proveniente de uma artĆ©ria
sistƩmica. Pode classificar-se em sequestro intralobar e sequestro
extralobar. Os sequestros intralobares raramente sĆ£o diagnosticados
nos lactentes.
Caso clĆnico: Descrevemos o caso clĆnico de um lactente
de dois meses de idade, com quadro de insuficiĆŖncia cardĆaca
congestiva, cuja investigaĆ§Ć£o revelou a presenƧa de um sequestro
intralobar. O cateterismo cardĆaco confirmou a presenƧa de
vaso anĆ³malo com origem na porĆ§Ć£o inferior da aorta torĆ”cica
irrigando o lobo pulmonar inferior esquerdo. Foi submetido a lobectomia
do lobo inferior esquerdo e laqueaĆ§Ć£o do vaso, com
resoluĆ§Ć£o do quadro.
DiscussĆ£o/ConclusĆ£o: O sequestro pulmonar intralobar Ć©
uma causa pouco frequente de insufi ciĆŖncia cardĆaca no lactente.
O diagnĆ³stico requer um elevado grau de suspeiĆ§Ć£o clĆnica para
que seja instituĆdo o tratamento eficaz e de forma atempada. ABSTRACT
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.
