Paratracheal air cysts are a rare entity in which cystic formation occurs adjacent to the trachea. Most patients with paratracheal air cysts are asymptomatic, and the cysts are detected incidentally on chest radiograph or computed tomography (CT) scan. Most symptomatic patients complain of pulmonary symptoms or repeated respiratory infection. Rarely, the air cysts can lead to paralysis of the recurrent laryngeal nerve as a result of direct compression. We report a case of a 59-year-old male patient who presented with voice change, and the cause was identified as paratracheal air cysts on a chest CT scan. Surgical resection via video-assisted mediastinoscopy was performed, and the voice recovered immediately after the operation.

During the emergency situation such as cardiac arrest, cardiopulmonary resuscitation(CPR) is the most important treatment to maintain patient's blood circulation. Since the quality of CPR can not be easily measured or evaluated by the eye, an assistive device with an accelerometer can help to assess the pressure depth of CPR. In this study, we propose a single frequency analysis method to reduce the error of the accelerometer by extracting only one frequency component from the Fourier transform process. To verify the effectiveness of the single frequency analysis, acceleration data at CPR conditions were measured at a sampling rate of 50 / sec using a wristband equipped with an acceleration sensor. Then, We compared the existing distance estimation method and the single frequency analysis method using the measured data. The amplitude value proportional to the compression depth was obtained by applying the single frequency analysis method.

Tuberculous spondylitis is the most common manifestation of musculoskeletal tuberculosis (TB). The progression of the disease is usually slow and insidious. The main symptom, back pain, is not specific, which frequently results in a delayed diagnosis resulting in neurologic deficits and more advanced vertebral destruction. It is more difficult to diagnose the disease if the involved area is an uncommon sites, such as the upper thoracic, cervical or sacral region. It is important to make an early diagnosis and treatment to achieve a better treatment outcome. We reported a 29 year old female with upper thoracic TB spondylitis(T2-8) and pulmonary TB complaining of back pain that persisted for 5 months and fever. TB spondylitis was not suspected to be due to upper thoracic involvement despite her pulmonary tuberculosis. Chest CT for the evaluation of pulmonary TB found T5 destruction and the paravertebral abscess that was consistent with TB spondylitis. Her spine was examined by MRI, which made an early diagnosis before the neurologic deficit had developed. She was treated with surgical intervention due to the spinal instability and anti-TB medication for 1 year with excellent results.

Tracheo-innominate artery fistula[TIF] is the uncommon delayed fatal complication of tracheostomy. The mortality rate of the lesion, if not treated surgically, approaches 100%. A 64-year-old man presenting with a TIF after tracheostomy was treated by lateral repair and muscle interposition between the innominate artery and trachea. Preoperatively, bleeding was controlled by gauze packing around the tude under manual compression and hyperinflation of the balloon cuff of the tracheostomy tube. No abnormality was found by angiographic evaluation. The patient failed to regain consciousness and died 4 days later from sepsis.

Tracheo-innominate artery fistula is a rare, but it is one of the gravest complications next to tracheostromy. Early recognition and prompt surgical management is mandatory. The patient was a 66 year old women with MCA infarct who maintained tracheostomy for lyear. She had respiratory arrest due to the excessive bleeding through the tracheostomy site. We report an successful experience for control of bleeding by an innominate artery fistula division and primay suture closure under direct digital compression.

The authors report a case of double aortic arch associated with complete transposition of the great arteries. On 7th, Feb. 1985, Rastelli operation was performed for transposition using extracardiac valved conduit. Postoperative course was complicated by persistent right lower lobe atelectasis which resulted from tracheal compression by double aortic arch. On 20th, Mar. 1985, left arch was divided distal to the left subclavian artery followed by complete resolution of the atelectasis. To the best of our knowledge, this is the first case ever reported in Korea.

Lymphangioma, or cystic hygroma, a malformation resulting from the sequestration of lymph vessels, is owing to a failure of the primitive jugular lymphatic sacs to join with the venous system. They are rare benign lesions found more frequently in children than in adults. We experienced a case of huge mediastinal lymphangioma in 37-year-old female patient. It was associated with a cervical prolongation, and caused deviation and compression of the trachea and the heart. The cervicomediastinal lymphangioma was completely resected by means of median sternotomy, and the post-operative course was unevenful.

Thoracic Outlet syndrome is defined to compression of the subclavian vessels and brachial plexus at the superior aperture of the thorax. It was previously designed due to presumable etiologies such as scalenus anticus, costoclavicular, hyperabduction, cervical rib or first rib syndromes. We experienced a case of thoracic outlet syndrome[scalene anticus syndrome] .Patient has been suffered from swelling and numbness of the right forearm and hand for 2 years. Diagnosis was made by preoperative selective angiography. Scalenus anticus and medius muscle resction and first rib resection was done with transaxillary approach. Postoperative course was not eventful.

Esophageal perforation, regardless of the etiology, is a catastrophic event. The importances of early diagnosis and an aggressive surgical approach in the management of such a potentially lethal situation are stressed, in fact the mortality rate is directly related to the interval between perforation and initiation of treatment. We experienced a rare case of esophageal rupture caused by compressed air which produce a rupture of the colon not infrequently, which was treated successfully by an aggressive surgical approach consisting of closure of the perforation and adequate drainage.

Atelectasis with chronic pneumonitis affecting the right middle lobe secondary to compression of the middle lobe bronchus by enlarged indurated or calcified peribronchial nodes is defined as middle lobe syndrome clinicopathologically. The lesion in this series of case reports including tuberculous lymphadenitis, lung cancer, atelectasis and lung abscess with organizing pneumonitis, had been treated by lobectomy. Postoperative courses were uneventful in all patients. Herewith, we report these four experiences with review of literature.
