Pulmonary sequestration Is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and which receives its blood supply from an anomalous systemic artery instead of a pulmonary arterial branch. Two forms of pulmonary sequestration occur: Intralobar sequestration, in which the abnormal pulmonary tissue is incorporated within the normal lung and shares a common covering of visceral pleura, and extralobar sequestration, in which the abnormal pulmonary tissue is separated from the normal lung and has its own pleural investment. Since 1970, five cases of pulmonary sequestration were operated at the Department of Thoracic and Cardiovascular Surgery, College of Medicine, Seoul National University. 1. Among five cues, one was male and the others were female. 2. All were intralobar type and involved left lower lobe. 3. There was no operative mortality following left lower lobectomy and ligation of the aberrant artery.

A 60-year-old female entered the emergency unit with a chief complaint of hemoptysis. Based on the computer tomographic image analysis of the chest, the patient was diagnosed as having an intralobar pulmonary sequestration that accompanied a hemothorax, and the hemothorax was do to the rupture of a pseudocyst. Pulmonary lobectomy of the left lower lobe and primary closure of an aberrant artery were both performed as an emergency operation. After one week following the operation, the patient was discharged without any postoperative complications.

Bronchopulmonary sequestration (BPS) is a rare congenital malformation of the lower respiratory tract. Most intralobar BPSs are provided with an arterial blood via the thoracic or abdominal aorta but such a supply is rarely found in patients older than 50 years. We report a case of an intralobar BPS with a dual arterial supply from the celiac artery and thoracic aorta in a 50-year-old man presenting with a respiratory tract infection and haemoptysis. To our knowledge, this is the first case report of a BPS supplied by the celiac artery and thoracic aorta in a 50-year-old man.

Pulmonary sequestration is applied to the congenital malformation characterized by an area of embryonic lung tissue that derives its blood supply from an anomalous systemic artery. Two cases of pulmonary sequestration were treated at the department of thoracic and cardiovascular surgery, college of medicine, Hallym University. One case was extralobar type, associated with the pneumothorax due to rupture of bulla. The other was intralobar type with symptom of massive and recurrent hemoptysis. The supplying arteries of both cases arose from the thoracic aorta. The venous return of the extralobar type was systemic into the hemiazygos vein, and that of the intralobar type was normal into the inferior pulmonary vein. Treatment for the former was resection of the sequestrated lung, and that for the latter was lobectomy of the left lower lobe. With the brief review of literature, we report the cases.

This is a case report of surgical management of a bilateral intralobar pulmonary sequestration with horseshoe lung presenting with frequent U I with productive sputum. Simple chest X-ray showed pneumonic consolidation and infiltration on both lower lobes, and chest CT revealed multiple cystic lesions compatible with pulmonary sequestration. The aortography demonstrated two anomalous systemic arteries arising from the thoracic aorta just above the diaphragm to both sequestrums. Left lower lobectomy was performed through the left thoracotomy with ligations and divisions of the both systemic feeding arteries to the left and right sequestrum, and division of the isthmic portion of horseshoe lung without removal of right sequestrum. The patient was discharged on the postoperative loth day and followed-up till now without any sequelae and symptoms of residual right sequestration. The recent follow-up chest CT 5 months after the operation revealed spontaneous regression of the residual right sequestrum. Authors would suggested that only division of aberrant artery to sequestrum without lobectomy may be applied in uncomplicated ca e of intrapulmonary seqilestration.

Pulmonary sequestration is a congenital malformation characterized by an area of embryonic lung tissue that derives its blood supply from an anomalous systemic artery. Two forms recognized: extralobar and intralobar. Extralobar form is a very rare congenital malformation, usually located in the lower chest, and may be found in newborn infants at the time a congenital diaphragmatic hernia is repaired. Large sequestrated segments may be cause acute respiratory distress in the neonate. The condition is asymptomatic in 15 per cent of patients. This report presents two cases of pulmonary sequestration which misdiagnosed a superior mediastinal tumor and a benign lung tumor. First case was 30-year-old male patient and chief complaints were dyspnea, dry cough and right chest pain. Chest X-ray showed a homogenous increased density of smooth margin at the right superior mediastinal area and suggested a benign mediastinal tumor. And so explothoracotomy was made without other special studies. Second case was 28-year-old male patient. One month ago, he had tracheostomy and right closed thoracostomy due to massive hemoptysis and spontaneous hemothorax. Chest X-ray showed a benign cystic lesion at RLL area. At the time of operation, in first case, a mass of adult fist size was placed medial to the right upper lobe and densely adhesive to trachea, SVC and esophagus. Blood supply of the mass was bronchial arteries of trachea and RUL bronchus and drained to SVC and azygos vein through anomalous systemic veins. There was no bronchial communication on Frozen biopsy. In 2nd case, large cystic lesion contained old blood hematoma was located in RLL and anomalous blood vessel from thoracic aorta was drained to posterior segment of RLL. In operation field, intralobar pulmonary sequestration was diagnosed, and RLL lobectomy was carried out.

The pulmonary sequestration is an uncommon congenital anomaly characterized by the presence of a part of lung tissue which is supplied by an aberrant artery from the aorta or its branch and usually has no communication with the normal bronchial tree. It was first presented by Hubber in 1777 and presented in details by Pryce in 1946. We present a case of extralobar pulmonary sequestration experienced recently with a case of intralobar type experienced in 1962. The patient was 11 year old male with the complaint of chronic productive cough. Serial chest films showed a large cyst with or without the air-fluid level on the posterobasal segment area of the left lower lobe. Bronchography showed no definite communication between the cyst and bronchial tree. On operation, the cystic lesion was supplied by an aberrant artery from the descending thoracic aorta 5 cm above the aortic hiatus and was sited at the posterobasal segment area of the left lower lobe. We performed the sequestrectomy and the sequestration was surrounded by its own pleura, 6.8x3.9x3.2 cm in size, contained the pale brown mucoid secretion in a large cyst and showed the primitive alveolar structure of the wall. The aberrant artery was 1 -5 cm long, 0.3 mm in internal diameter and arterio-sclerotic. We also compared 6 cases of collection, 5 intralobar and 1 extralobar type, presented in Korea.

Bronchopulmonary sequestration is a rare congenital malformation of the lung, concerning about the abnormal feeding systemic artery, may happen a serious complication of heeding during operation if not recognized before operation. High index of suspicion of sequestration is the key to successful operative procedure with the aid of characteristic recurrent and long-standing symptoms, its location, and invasive or non-invasive diagnostic tools. We report 2 cases of intralobar type of bronchopulmonary sequestration and review 10 articles about the subject, totaling of 21 cases.

Pulmonary sequestration is a rare congenital malformation of the lung and occasionally accompanied with upper gastrointestinal anomalies. Based on the embryologic development, they are grouped as broncho-pulmonary foregut malformation. We present one the case of the intralobar pulmonary sequestration with gastric duplication. The sequestrated pulmonary tissue was 9x7x8cm in dimension, multiseptated and multiloculated, and supplied by a systemic artery of 7mm diameter from the abdominal aorta. The gastric duplication was 8cm in diameter located at the posterior wall of the stomach without communication with the gastric lumen.

A 42-year-old female was admitted to our hospital complaining of a dyspnea. Chest X-ray showed left atelectasis. A mass was detected in left main bronchus by computed tomography and bronchoscopy. The mass was diagnosed as a endobronchial leiomyoma by biopsy exam. After open thoracotomy and bronchotomy, mass removal was done and middle lobe was ventilated normally. Aberrant arterial supply from descending aorta to left lower lobe of the lung was detected and left lower lobectomy was done. The lower lobe of the left lung was pathologically diagnosed as intralobar pulmonary sequestration. Herein we report a rare coexistent case of endobronchial leiomyoma and intralobar pulmonary sequestration.
