  • The operative case of transmanubrial osteomuscular sparing approach for the tumor involving thoracic inlet is reported. A 69-year-old man visited the hospital due to right upper extremity weakness. Chest roentgenogram showed bronchiectasis, chronic pulmonary tuberculosis, and fungal ball in right upper lobe. On computed tomogram, tumor was located in epidural space of the 6th, the 7th cervical, and the 1st thoracic spine and extended to the apex of the right thorax. A neurosurgeon performed laminectomy and removed the tumor located in the spinal canal. A thoracic surgeon performed a transmanubrial osteomuscular sparing approach and removed the tumor involving thoracic inlet. The tumor was diagnosed as hemangiopericytoma. The patient recovered without complication.

  • Superior sulcus or pancoase tumor refers to any primarty lung cancer locating in thoracic inlet and causing pain in the periscapular region or aim. These originate inperipheral, and involve th extrapulmonary structures more than parenchyma of the lung. We experienced l case of superior sulcus tumor radically resected via anterior transcervical approach, which provide more safe exposure of cervical structures of thoracic inlet than classis posterolateral thoracotomy. Therefore were report this case with review of literature.

  • Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.

  • Patients with double-inlet left ventricle usually have a small ascending aorta. In the Norwood procedure, which involves a staged operation, a neoaorta is constructed with a homograft, and the pulmonary artery plays a role in the systemic circulation. Dilatation or aneurysmal changes can occur over time due to the exposure of the neoaorta to systemic pressure, which may induce adverse effects on adj acent structures. We report a rare case of surgical repair for neoaortic root dilataiton with aortic regurgitation, compressing the left pulmohary artery, in a patient who underwent the Norwood procedure.

  • An 8-year-old intact male Pekingese (weighing 13 kg) was presented for evaluation of chronic coughing. Thoracic radiography found a redundant tissue swelling (protruded on expiration and collapsed on inspiration) on the ventral neck just cranial to the thoracic inlet. Fluoroscopy also identified that the cranial portion of the right/left cranial lung lobe was seen to protrude through the thoracic inlet into the ventral neck on expiration. On the echocardiogram, there were no abnormal jets in all cardiac valves and no dilation in all cardiac chambers. Based on diagnostic imaging studies, the case was diagnosed as cervical lung lobe herniation.

  • Particulate matter smaller than $10{\mu}textrm{m}$ in aerodynamic diameter (PM10) is known as thoracic particles that are capable of reaching the thoracic region of humans. PM10 is further divided into two size ranges, which are fine particles (nuclei mode plus accumulation mode) and coarse particles, based on different sources and chemical composition. Fine particles can penetrate deep into the alveolar region of the human lungs, while coarse particles be deposited in the upper respiratory system. (omitted)

  • Background: Although considerable efforts have been made to improve the graft patency in coronary artery bypass surgery, the role of biomechanical factors remains underrecognized. The aim of this study is to investigate the influences of geometric configurations of the bypass graft on hemodynamic characteristics in relation to anastomosis. Materials and Methods: The Numerical analysis focuses on understanding the flow patterns for different values of inlet and distal diameters and graft angles. The Blood flow field is treated as a two-dimensional incompressible laminar flow. A finite volume method is adopted for discretization of the governing equations. The Carreau model is employed as a constitutive equation for blood. In an attempt to obtain the optimal aorto-coronary bypass conditions, the blood flow characteristics are analyzed using in vitro models of the end-to-side anastomotic angles of $45^{\circ}$, $60^{\circ}$ and $90^{\circ}$. To find the optimal graft configurations, the mass flow rates at the outlets of the four models are compared quantitatively. Results: This study finds that Model 3, whose bypass diameter is the same as the inlet diameter of the stenosed coronary artery, delivers the largest amount of blood and the least pressure drop along the arteries. Conclusion: Biomechanical factors are speculated to contribute to the graft patency in coronary artery bypass grafting.

  • Criss-cross heart which is a cardiac malformation caused by abnormal rotation of the ventricles early in embryonic development, is rare but a double outlet of right ventricle in priss-cross heart is very rare. We experienced a case of criss-cross heart which is situs solidus, concordant atrioventricular connection and double outlet of rig t ventricle with remote ventricular septal defect of perimembranous inlet type. A 4-years old female was diagnosed as a double outlet of right ventricle in criss-cross heart after echocardiography, cardiac catheterization and cardiac angiography. The surgical correction was a intraventricular reconstruction of left ventricular outflow with 314 circle of 20 mm Hemashield vascular graft from the ventricular septal defect to the aorta. The patient had a temporary atrioventricular block but was recovered uneventfully, and a postoperative echocardiogram showed no left ventricular outflow obstruction, no intracardiac shunt.

  • The Rastelli operation has been a standard procedure for repairing complete transposition of the great arteries combined with a ventricular septal defect and pulmonary stenosis. Yet this procedure has several shortcomings, including the risk of incurring left ventricular outflow tract obstruction on long-term follow-up. In this regard, aortic translocation has recently been regarded as a potent alternative to Rastelli's operation. We report here on a case of complete transposition of the great arteries that was combined with an inlet-extended perimembranous ventricular septal defect and pulmonary stenosis in a 2-year-old boy. All the problems were successfully repaired using the aortic translocation technique. Postoperative echocardiography showed a straight and wide left ventricular outflow tract.

  • A 17 year-old high school girl was admitted for anterior chest pain. Pulmonary edema and circulatory collapse progressed in spite of the medical treatment and intra-aortic balloon pump. Left ventricular assist device(LVAD, Bio-Pump, Medtronic Bio-Med, USA) was instituted under the impression of acute fulminant myocarditis. The inlet cannula was inserted in the left atrium(LA) via left submammary anterior thoracotomy. Biopsy was taken from left atrial appendage. The outlet cannula inserted to the left femoral artery using PTFE cuff. After 158 hours of extracorporeal circulation, LVAD was able to be weaned successfully with nearly normalized LV motion on echocardiogram, Coxsakievirus was identified with immunochemistry and serum neutralization test. She was discharged without any heart failure symptoms after 23 days of hopitalization.
