“…An ELPS is typically irrigated by an artery originating directly from the aorta, and, in 80% of cases, venous drainage is systemic, occurring via the azygos-hemiazygos system or via the superior vena cava, which creates a left-toright shunt. (2,5) Unlike in cases of ILPS, clinical manifestations appear in the first six months of life in cases of ELPS. Neonatal asphyxia, dyspnea, and venous contrast has allowed definitive diagnosis because of its enhanced capacity to depict communication between the anomalous artery and the PS.…”

“…More rarely, recurrent episodes of respiratory tract infection or gastrointestinal symptoms can occur. (2,11) Cases of ELPS can be accompanied by pulmonary, cardiac, and vertebral malformations, as well as by malformations of the chest wall and gastrointestinal tract, being most commonly accompanied by diaphragmatic hernia. (12) On chest X-rays, PS can be initially identified as a mass of homogeneous opacity.…”

“…Accidental transection of an anomalous systemic artery can cause massive hemorrhage with fatal consequences, and it is of paramount importance that anomalous vessels be identified in the preoperative period. (2) The objective of the present study was to report an intraoperative finding of PS following hemorrhage resulting from the transection of an anomalous pulmonary vessel during resection of a carcinoid tumor.…”

Pulmonary sequestration is defined as a mass of lung tissue separated from the tracheobronchial tree and irrigated by an anomalous systemic artery. It is rarely seen in conjunction with lung neoplasms. We report the case of a 39-year-old female patient diagnosed with a carcinoid tumor, located in the intermediate bronchus and accompanied by bronchiectasis in the right lower lobe. The patient underwent thoracotomy for the resection of the affected area. During surgery, she presented with significant hemorrhage resulting from the transection of the anomalous artery that irrigated an intralobar pulmonary sequestration, which was located in right lower lobe and had not been identified in pre-operative examinations.Keywords: Bronchopulmonary sequestration; Hemorrhage; Carcinoid tumor. ResumoO sequestro pulmonar é definido como uma massa de tecido pulmonar separada da árvore traqueobrônquica e irrigada por uma artéria sistêmica anômala. Sua associação com neoplasias pulmonares é rara. Relatamos o caso de uma paciente de 39 anos com o diagnóstico de tumor carcinoide localizado no brônquio intermediário, associado a alterações caracterizadas como bronquiectasias em lobo inferior direito. A paciente foi submetida à toracotomia para ressecção da área acometida e, durante a cirurgia, apresentou hemorragia importante decorrente da transecção da artéria anômala que nutria o sequestro pulmonar intralobar localizado em lobo inferior direito, não identificado nos exames pré-operatórios. Depending on its pleural covering, PS is classically divided into intralobar and extralobar. An intralobar PS (ILPS) share the pleural covering with the rest of the lung, whereas an extralobar PS (ELPS) is completely covered by its own visceral pleura. Descritores(5) Although the extralobar form is well defined as a congenital abnormality, the intralobar form has a controversial pathogenesis, with some evidence indicating that, in many cases, it is an acquired disease. (6,7) Accounting for approximately 75% of all cases of PS, ILPS is more common in the lower lobes and on the left, involving the posterior basal segment. (5,8) Its arterial supply is nearly always derived from the aorta or from one of its branches, typically one of a large diameter. Venous drainage is via the pulmonary veins into the left atrium, creating a left-to-left shunt. In a minority of cases, drainage is via the inferior vena cava or via the azygos system. (9) In the case presented here, the PS was located in the right lower lobe and the blood supply came from an anomalous branch derived from the thoracic aorta.Cases of ILPS typically occur in adolescents and young adults with a history of recurrent infections of the respiratory tract, hemoptysis, and dyspnea. Some ILPS patients develop cardiac symptoms, which are a consequence of the lefthemoptysis. In the preoperative investigation, a CT scan of the chest revealed a lesion in the intermediate bronchus (Figure 1), as well as cystic bronchiectasis in the right lower lobe (Figure 2).

“…Extralobar sequestration comprises B25% of all sequestrations and is covered by a separate pleural investment. 4 Intralobar sequestration shares a pleural investment with the ipsilateral lung, which may become aerated through the pores of Kohn. The ELS are nonaerated masses.…”

“…4 The venous drainage of ELS is usually through the systemic circulation into the hemiazygos veins, azygos veins, inferior vena cava or portal vein. 2 Approximately 65% of ELS are located on the left side and 70% of these are located between the left lower lobe and the diaphragm.…”
