The Compression of Left Main Bronchus Caused by Dilated Descending Aorta After Ligation of PDA / 대한흉부외과학회지

Vascular compression of the tracheobronchial tree can create troublesome respiratory problems after an otherwise successful correction of a cardiac defect. This case represents a left main bronchial obstruction caused by dilated descending aorta after ligation of patent ductus arteriosus. An 8-month-old boy received an operation of mitral valve repair and PDA ligation due to mitral regurgitation and PDA. After the operation, atelectasis of left lung developed. The left main bronchial obstruction by dilated descending aorta was found on chest CT scan. The second operation was done. In the operative field, it was found that the sight of ligation of PDA was too close to left pulmonary artery, and redundant descending aorta compressed anteriorly left main bronchus. Ligated PDA was divided, the redundant descending aorta was opened and sutured to decrease the size. After the operation, atelectasis of left lung was resolved.

Exophagectomy Combined with Resectiion of Invaded Aorta for T4 Esophageal Carcinoma / 대한흉부외과학회지

Advanced esophageal carcinoma which invades into adjacent organs are classified as T4 esophageal cancer,. Its complete resection without residual tumor would be difficult. Preoperative chemoradiotherapy and combined modality therapy are being tried to improve survival in patients with T4 esophageal carcinoma. In a 74-year-old man a 6cm squamous cell carcinoma of the esophagus with invasion of the thoracic aorta was detected (T4). After neoadjuvant chemoradiotherapy the patient was operated on using bio-pump with aorto-femoral cannulation. The invased segment of descending aorta was resected and reconstructed with a graft. The tumor was resected and EG anastomosis was done. The postoperative period was uneventful the patient was discharged after good condition and has been well to now.

Tracheal augmentation with Bovine pericardium / 대한흉부외과학회지

This case describes a tracheal stenosis complicated by endobronchial truberculosis. A 50-year-old female with progressive dyspnea was referred to us for the management of long segmental tracheal stenosis. Treatment modalities for tracheal stenosis include open surgical resectin and reconstruction, mechanical dilation, laser resection, and placement of an airway prosthesis. The following is a report of a successful treatment of a long segmental tracheal stenosis through a tracheal augmentation and the use of al Bovine pericardium. This technique may provide a relief from tracheal stenosis.

Postpneumonectomy Syndrome after Left Pneumonectomy: one case report / 대한흉부외과학회지

Postpneumonectomy syndrome is a rare and delayed complication of left pneumonectomy in most patients with normal mediastinal vascular anatomy. This syndrome is characterized by dyspnea and recurrent pulmonary infection in the remaining right lung that typically occur within the first postoperative year. The condition is believed to be secondary to postsurgical changes that include a marked shift of the mediastinum to the left, clockwise rotation of the heart and great vessels, and herniation of the right lung into the left anterior thorax. These changes lead to compression of the trachea or right main bronchus among the thoracic spine and the right pulmonary artery. We report a case of postpneumonectomy syndrome in 15 year-old girl that followed by left pneumonectomy for bronchiectasis 6 years ago. We have inserted an expandable prosthesis in the left thoracic cavity posterior to the heart. After implantation of an expandable prosthesis, an anatomic reposition of the shifted mediastinum was achieved, which resulted in instantaneous and sustained relief. The post-operative course was uneventful and the patient was followed in OPD from after discharge to now.
