Aneurysmal dilatation of the ductus arteriosis has been considered a rare but potentially fatal abnormality. The mechanism of ductal aneurysmal formation remains uncertain. Plain chest radiography has proven helpful in the diagnosis of ductus arteriosus aneurysm (DAA), before the application of transthoracic echocardiography. The transthoracic echocardiography is an important tool for the diagnosis and follow-up of DAA. We present a case of congenital ductus arteriosus aneurysm in a newborn, that was an incidental discovery. The diagnosis was made by echocardiography, three-dimensional surface rendering computed tomography (CT), and spontaneous regression after four weeks of follow-up.

Background : Advanced thymic cancer still remains as an intractable disease. The survival rate of advanced thymic cancer could be increased through chemotherapy and radiation, but the results have not been satisfactory. Objectives : To see whether wheel balanced therapy (WBT) has the therapeutic effects or not on advanced thymic cancer patient. Methods : A patient diagnosed with progression of thymic carcinoma with pleura metastasis visited the East-West Cancer Center (EWCC) on Feb 9th, 2011. The patient was treated with WBT for a period of 9 weeks from Feb 9th to Apr 16th. She stayed 6 weeks in hospital and took oriental medicine prescribed by EWCC. Computed tomography (CT) and blood test were used to evaluate the disease progression of the patient. Results : Mass of chest CT was stable for 2 months. The patient's quality of life improved during her hospital stay. Conclusions : This case study supports WBT may have efficacy in treating advanced thymic cancer patients.

We herein present a case of a successful correction of cor triatriatum associated with thrombotic pulmonary hypertension diagnosed in an adult female patient. We confirmed diagnosis using transthoracic and transesophageal echocardiography in addition to cardiac computed tomography and magnetic resonance imaging. Surgical repair comprised excision of the fibromuscular membranous septum in the left atrium, patch closure of an atrial septal defect, and reconstruction of the pulmonary arteries with a vascular graft. Cor triatriatum complicated pulmonary thrombotic hypertension with atrial septal defect is amenable to surgical correction with satisfactory results.

We performed a hybrid procedure for a 58-year-old man with coronary artery disease and a left subclavian artery stenosis. He underwent left subclavian artery stenting and off-pump coronary artery bypass surgery, including grafting the in situ left internal mammary artery to the left anterior descending coronary artery. The post-operative coronary angiogram and computed tomography showed good patency of the graft and stent. He discharged at postoperative 8 days and he has been followed up for six month with an excellent clinical condition.

A 67-year-old female patient was treated with conventional total arch replacement and insertion of a stented elephant trunk (SET) graft into the descending thoracic aorta for acute DeBakey type I aortic dissection at one time. She had been treated with right coronary artery stent insertion for acute myocardial infarct 4 days earlier, and at that time, she was diagnosed with acute DeBakey type I aortic dissection from the ascending aorta to the suprarenal artery based on trans-esophageal echocardiography and aorta computed tomography. Through a median sternotomy, we inserted the SET graft through the opened aorta to the descending aorta. We also performed anastomosis between the proximal stented graft and the distal aortic arch, and then performed total arch replacement. For acute DeBakey type I aortic dissection, we report total arch replacement with insertion of a SET graft as a combination of conventional surgery and the interventional technique.

An 81-year-old male patient presented with complaint of a pulsating neck mass. The patient had a previous history of cervical lymphadenopathy by non-tuberculous mycobacterium infection. Rapid growth of the mass on admission and contrast enhanced computed tomography of the neck resulted in a diagnosis of non-tuberculous mycobacterium induced pseudoaneurysm. The patient underwent emergency open repair of the pseudoaneurysm. Pseudoaneurysm of the common carotid artery is regularly reported, but here we report a rare case of non-tuberculous mycobacterium induced pseudoaneurysm of the common carotid artery.

A 20-year-old man presented with a femur fracture and epidural hemorrhage (EDH) following a fall. One month after fracture surgery, swelling developed in both legs, and he was diagnosed as having a deep-vein thrombosis and pulmonary embolism. A retrievable inferior vena cava filter (IVCF) was inserted, because EDH is a contraindication to anticoagulants. Four months later, he complained of abdominal pain, and a computed tomography scan showed a fractured IVCF strut. After percutaneous removal failed 3 times, the IVCF was surgically removed by orthopedists using a portable image intensifier without cardiopulmonary bypass.

In the embryo, the thymus originates from the third and fourth pharyngeal pouches and migrates from the superior neck to the mediastinum. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic tissue, and is caused by the aberrant migration of the embryonic thymus. Our patient was a 30-year-old woman who had a nodular lesion in the neck for several years. Ultrasonography and computed tomography were performed. She underwent surgery, and a histological examination resulted in a diagnosis of type AB thymoma. Herein, we report a case of ECT that was resected through a transcervical approach.

Esophageal schwannoma is a very rare submucosal tumor. We report successful management of esophageal schwannoma in a 41-year-old man who complained of progressively worsening dysphagia. A huge submucosal tumor was found via endoscopy and a chest computed tomography scan. Esophagectomy was performed with no post-operative complications. Post-operative immunohistochemistry staining showed a positive result for S-100 and negative results for c-kit and CD34. The post-operative mild dysphagia persisted, and the follow-up endoscopic findings revealed anastomosis site stenosis. Approximately 2 months later, we performed endoscopic balloon dilatation. We report herein a case of esophageal schwannoma with reviews.

Tracheal diverticulum is relatively rare. It results from congenital or acquired weakness of the tracheal wall. Most cases are asymptomatic, but when symptoms are present, they are usually nonspecific. A 54-year-old man complained of sputum lasting for several months. Chest computed tomography showed an air-containing cystic structure in the trachea. Fiberoptic bronchoscopy demonstrated ostium arising from the right posterolateral wall at the trachea. Reported herein is a case of eosinophilic bronchitis associated with tracheal diverticulum.
