“…(1) A review of the national literature identified no reports of ELS with hemothorax secondary to lesion infarction. (9) In the international literature, only one such study was located. (2) esis for the infarction was that the torsion of the mass triggered a venous occlusion, followed by congestion and infarction secondary to arterial thrombosis.…”

Sequestro extralobar com hemotórax secundário a infarto pulmonar

2009

O sequestro pulmonar é uma malformação incomum, representando 0,5-6% de todas as malformações pulmonares, sendo geralmente diagnosticado na infância. Dos dois tipos de sequestro pulmonar, intralobar e extralobar, este último é o menos freqüente. O presente relato descreve o caso de um paciente do sexo feminino, de 32 anos, com quadro de dor toracoabdominal e achados de radiografia e TC de tórax revelando consolidação e derrame pleural. A conduta inicial com toracocentese evidenciou hemotórax. A seqüência diagnóstica através da videotoracoscopia permitiu o diagnóstico de sequestro extralobar e a consequente conduta de conversão para toracotomia para ressecção da lesão com ligadura segura do pedículo vascular intercostal.

Sequestro extralobar com hemotórax secundário a infarto pulmonar

“…In 1861, Rokitansky and Rektorzik described cases that appear to have been extralobar pulmonary sequestration, but the term "sequestration" was only proposed by Pryce in 1946 and, since then, the finding has been recognized as a clinical entity. 5,6 Two types of presentation of pulmonary sequestration are described in the literature: extralobar, in which there is total anatomic separation from the adjacent normal pulmonary parenchyma, and intralobar, in which the anomalous pulmonary segment is contiguous with the adjacent normal lung. 7 These malformation involve the lower lobes in more than 95% of cases and are more common on the left (55-60%).…”

Sequestro pulmonar e tratamento endovascular: um relato de caso

et al. 2019

Resumo O sequestro pulmonar refere-se à anomalia congênita definida por massa de parênquima pulmonar não funcionante. É dividido pela existência de envoltório pleural próprio em intralobar, representando cerca de 75% dos casos, ou extralobar, responsável pelos 25% restantes. O diagnóstico é feito através de radiografia e confirmado com tomografia computadorizada, ressonância nuclear magnética e arteriografia. Tradicionalmente, o tratamento proposto é cirúrgico, mas a técnica endovascular tem apresentado bons resultados. É relatado o caso de uma mulher, 29 anos, com quadro clínico de pneumonias de repetição desde os 5 anos. A tomografia de tórax revelou malformação vascular em região inferior de pulmão direito. O tratamento vascular foi realizado através de embolização do ramo anômalo.

“…More recently, reconstruction with multichannel CT scanners to-left shunt and of the high flow diverted to the anomalous vessel. (10) The recurrent episodes of infection cause fibrosis and visceral pleural thickening. The lung parenchyma shows areas of consolidation and fibrosis containing multiple cystic formations, which can be mistaken for bronchiectasis, (5) as in the case reported here.…”

“…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. (10,13) The treatment for PS is surgical resection of the sequestered lobe or segment by thoracotomy or even by video-assisted thoracoscopy. In both cases, the success of the procedure depends on adequate knowledge of the vascular anatomy of the PS and on early ligation of the artery irrigating the PS, because, as previously stated, accidental transection of that artery can lead to massive hemorrhage, with fatal consequences.…”

Tumor carcinoide e sequestro pulmonar

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). Fiberoptic bronchoscopy confirme...
