Intralobar Pulmonary Sequestration in 22 year-old Male: Case report and review of literature

Pulmonary sequestration is a rare congenital malformation of the lower respiratory tract characterized by a non-functioning mass of lung tissue that is not communicating with the normal tracheo-bronchial tree and receives its vascular supply from a systemic artery. We report the first case of intrapulmonary sequestration in Qatar, of a 22 year-old Qatari male who presented with recurrent chest infection. This case study includes a literature review.

Intralobar pulmonary sequestration: an uncommon case with triple arterial supply and systemic venous drainage

Pulmonary sequestration is a rare congenital pulmonary malformation. We report a case of a 10-month-old infant with intralobar pulmonary sequestration diagnosed in utero. The lesion had an uncommon blood supply consisting of three large arteries deriving from the thoracic aorta and venous drainage into the inferior vena cava.

Robotic thoracoscopic resection of intralobar sequestration.

In this manuscript we report a case of fully robotic thoracoscopic resection of intralobar pulmonary sequestration. The Da Vinci robot provides surgeons with great three-dimensional visualization and enhanced dexterity. This enables a safer, more precise dissection of sequestered pulmonary tissue. Robotic technology may result in fewer complications and less conversions to open surgery in cases of pulmonary sequestration.

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.

Pulmonary Sequestration and Diaphragmatic Eventration in a 6-month-old Infant

A congenital pulmonary malformation, such as pulmonary sequestration or congenital cystic adenomatoid malformation, should be suspected in infants with recurrent lower respiratory symptoms or unifocal infiltrations. The possibility of congenital pulmonary malformation associated with additional abnormalities, such as diaphragmatic hernia, is relatively high and can lead to misdiagnosis. We report a case of a 6-month-old girl who presented with relapsing respiratory infection and hematemesis. Computerized axial tomography scan and barium swallowing study were performed, revealing a suspected intralobar pulmonary sequestration associated with sliding gastric hernia. Since the patient's condition was complicated by sliding hernia, pneumonia and pleural effusion, a surgical procedure instead of cardiac catheterization with coil embolization was performed. During surgery, the absence of a sliding gastric hernia but a diaphragmatic eventration was noted. Only a partial portion of the left-side diaphragm was relaxing, making the barium swallowing study difficult to interpret. This case serves as a reminder that if pulmonary sequestration is suspected, a full work-up with a complete set of imaging studies should be ordered for the possible detection of associated gastrointestinal, respiratory and thoracic abnormalities.

Intralobar Pulmonary Sequestration Showing Increased Serum CA19-9

Carbohydrate antigen 19-9 (CA19-9) is a specific tumor marker of the biliary, pancreatic and gastrointestinal tracts. CA19-9 is occasionally elevated in serum in patiens with benign pulmonary diseases such as bronchiectasis, idiopathic interstitial pneumonia or collagen disease-associated pulmonary fibrosis. Intralobar pulmonary sequestration is an uncommon congenital lung anomaly. It is dissociated from the normal tracheobronchial tree and is supplied by an anomalous systemic artery. There have been some reports of elevation of CA19-9 in this lesion. We report a case of intralobar pulmonary sequestration with elevated serum CA19-9 in a 29-year-old man who was diagnosed with bronchiectasia of left lower lung field on general check up. He had no evidence of any malignant disease in pancreatobiliary or gastrointestinal tracts. Elevated serum CA19-9 level might be encountered with benign pulmonary disease such as pulmonary sequestration.

A Patient with Intralobar Pulmonary Sequestration: A Rare Congenital Anomaly

A 51-year-old male patient had a history of recurrent pneumonia since the second decade of life. Interestingly enough, chest X-rays showed the same radiological pattern with involvement of the left lower lobe. A multislice spiral CT scan of the chest was performed and depicted an anomalous arterial vessel emerging from the descending thoracic aorta towards the left lower pulmonary lobe, characterizing pulmonary sequestration. The findings were confirmed by thoracic aortography, and the patient was referred for surgical treatment. Paciente com Sequestro Pulmonar Intralobar: Uma Rara Anomalia Congênita Paciente do sexo masculino, com 51 anos de idade, com história de pneumonias de repetição desde a segunda década de vida. As radiografias de tórax curiosamente demonstravam o mesmo padrão radiológico com envolvimento do lobo inferior esquerdo. Foi realizada tomografia helicoidal de tórax, que revelou vaso arterial anômalo emergindo da aorta torácica descendente em direção ao lobo pulmonar inferior esquerdo, caracterizando sequestro pulmonar. Os achados foram confirmados por aortografia torácica, sendo o paciente encaminhado para tratamento cirúrgico.

Intralober Pulmonary Sequestration with Arterial Supply from Two Different Origins: A Case Report

Pulmonary sequestration is a rare anomaly, which does not have a connection with the bronchial system and gets its blood supply, generally, from the aorta or its branches. Anatomically, two different forms were described: intralobar and extralobar. Although 74% of intralobar pulmonary sequestrations get their blood supply from the descending thoracic aorta, they may get their blood supply from different arteries. Furthermore, there is more than one arterial anomaly in 14.8% of cases. We report an intralobar pulmonary sequestration, in which arterial blood supply is from two different origins (Arcus aorta and celiac trunk). To the best of our knowledge, this is the first case in the literature.

Massive Hemoptysis in a Case of Intralobar Pulmonary Sequestration Associated with Pulmonary Hypoplasia and Meandering Right Pulmonary Vein: Diagnosis and Management

Pulmonary sequestration is a congenital malformation characterized by focal area of dysplastic lung tissue that lacks normal communication with tracheobronchial tree and receives blood supply from systemic arteries. Surgical resection has been the conventional method of treatment of pulmonary sequestration. In recent years transarterial embolization of the anomalous systemic arteries has emerged as a suitable alternative to surgery. In this paper, we describe transarterial coil embolization for control of massive life-threatening hemoptysis in a rare case of intralobar sequestration in right lung associated with ipsilateral pulmonary hypoplasia and meandering right inferior pulmonary vein. A 3-year follow-up computed tomographic (CT) angiography revealed complete regression of the sequestration along with altered pulmonary arterial contour. To the best of our knowledge, transarterial coil embolization for control of massive life-threatening hemoptysis in such a complex pulmonary anomaly has not yet been reported.

A Case of Bilateral Pulmonary Sequestration

Pulmonary sequestration is a rare congenital anomaly of the lung in which it is separately supplied from the aorta or one of its branches. Bilateral pulmonary sequestration is very rare, particularly in adults. In bilateral pulmonary sequestration, resection of both sides is usually recommended if both sides are infected and symptomatic. We report the case of a 37-year-old female patient with bilateral intralobar pulmonary sequestration treated by staged bilateral lower lobectomy.

An unusual presentation of recurrent pneumonia

In October, 2010, a 20-year-old man was referred to us after having been admitted to hospital four times with community acquired pneumonia since the age of 16 years. His recurrent symptoms included a productive cough, lethargy, fever, night sweats, and rigors. Apart from child-hood asthma, he had no important medical history of respiratory illness. He was a life-long non-smoker and denied illicit drug use. Auscultation of the chest showed equal air entry to the lung fi elds with mild crepitations in the left lower zone posteriorly. Erect chest radiography showed multiple cystic lesions in the left lower lobe posteriorly with crowding of bronchovascular markings (fi gure A). CT of the chest showed a systemic artery feeding a left lower lobe pulmonary sequestration (fi gure B). The feeding artery originated from the common hepatic artery before passing through the oesophageal hiatus into the thorax. Aberrant venous drainage from the sequestration was not identifi ed and a diagnosis of intralobar pulmonary sequestration was made.Our patient had a bronchoscopy with normal fi ndings, followed by a left posterolateral thoracotomy. Intra-operatively, the pulmonary sequestration was found to be strongly adherent to the diaphragm. An aberrant systemic artery was seen rising through the oesophageal hiatus and was suture ligated and divided. No other aberrant arteries or veins were identifi ed. The sequestered lung was resected by a routine left lower lobectomy. He had an unremarkable recovery and was discharged home on the fourth day postoperatively. Macroscopic pathological

Endovascular Treatment of Intralobar Pulmonary Sequestration with Vascular Plug: A Case Report

Pulmonary sequestration is a congenital malformation involving a mass of non-functioning pulmonary tissue that does not communicate with the bronchial tree or the pulmonary arteries (1). Intralobar sequestration is commonly seen in young adults with no symptoms or nonspecific symptoms, such as chest pain, dyspnea, and wheezing. Recently, several case reports documented that endovascular embolization with coils is a safe and effective alternative treatment replacing surgery when dealing with pulmonary sequestration (2-4). Also, the use of new occluding devices has been associated with high success rate and efficacy for the embolization of the aberrant artery to the intralobar sequestration from the aorta (5, 6). There has been no established regimen for endovascular treatment until now. As far as we know, we are the first to describe the successfully treated case of intralobar pulmonary sequestration by occlusion of the feeding artery with type II Amplatzer Vascular Plugs and antibiotic-soaked gelatin sponge particles in an adult.

A Pulmonary Sequestration with Massive Hemoptysis

Pulmonary sequestration is a rare malformation of the pulmonary parenchyma. Although pulmonary sequestration is rare finding but should be considered in patients with repeated episodes of bleeding. We describe a case of intralobar pulmonary sequestration found in a 27-year-old man admitted with massive hemoptysis and cough. He underwent lobectomy and achieved an excellent outcome. According to the potentially severe complications that they may cause, pulmonary sequestration should be removed whenever it is diagnosed; besides that repeated episodes of hemoptysis should be evaluated by more precise techniques such as ct angiography rather than broncoscopy.

Intralobar Pulmonary Sequestration Supplied by an Anomalous Aneurysmal Artery

Pulmonary sequestration is a relatively rare condition in which a systemic artery supplies blood to an abnormal lung tissue. Pulmonary sequestration with an aneurysmal systemic artery is extremely rare. We describe the case of a 52-year-old man with intralobar pulmonary sequestration supplied by an aneurysmal systemic artery. Because the nomenclature of pulmonary sequestration is still not clear, we propose that type 1 intralobar pulmonary sequestration be called "systemic arterial supply to the normal lung," as named by many professionals, and for this to be distinguished from pulmonary sequestration.

Video-assisted thoracic resection for intralobar pulmonary sequestration

We present a case in which video-assisted thoracic resection for intralobar pulmonary sequestration (ILPS) was successfully performed. A 36-year-old woman had repeated pneumonia. Chest computed tomography (CT) showed a round mass in the right lower lobe of the lung. Subsequent three-dimensional CT revealed that a large anomalous artery arising from the descending thoracic aorta was distributing to the posterior basal segment containing the lesion and was draining into the inferior pulmonary vein. The patient was diagnosed with ILPS and underwent surgery. The anomalous artery was divided, and the sequestered segment was completely resected by video-assisted thoracic surgery (VATS). We think that VATS resection for ILPS is feasible and is a major therapeutic option as noninvasive surgery.
