Aortic regurgitation in the pediatrics who had previous cardiac surgery is increased with their improved longterm survival rate and their complexity of heart disease. So the need of aortic valve surgery in pediatrics is also on the increase. A 10-year old boy was admitted for progressive cyanosis and dyspnea on exertion(DOE). The patient had been underwent lateral tunnel Fontan operation before. Echocardiography and cardiac catheterization study revealed hepatic vein drained to pulmonary atrium via intrahepatic collaterals, moderate atrioventricular regurgitation, and severe aortic regurgitation due to aortic root dilation. We report a case who had aortic root reconstruction, valvuloplasty of the atrioventricular valve, and hepatic vein ligation successfully Cyanosis and DOE was dramatically improved after the operation

Twenty two patients underwent total anatomic correction of complete atrioventricular septal defect associated with other cardiac anomalies between July 1986 and December 1994. Age ranged from 6 months to 11 years(mean 49.6 $\pm$ 35.8 months), and they were composed of 7 males and 15 females. Combined major cardiac anomalies were tetralogy of Fallot(TOF) in 11 cases, double outlet of right ventricle (DORV) in 6 ca es, and transposition of great arteries (TGA) in 5 cases. Down's syndrome was associated in 5 patients with TOF and 1 patient with DORV. They were classified as Rastelli type A in 3 patients, B in 2 patients, and C in 17 patients. Modified Blalock-Taussig shunt was performed.in 5 patients and Waterston shunt in 1 patient as a palliative procedure. There were 7 perioperative deaths(31.8%) and the causes were pump weaning failure, low cardiac output, acute renal failure, persistant pulmonary hypertension and hypertensive crisis, and sepsis. Reoperations were performed in 4 cases to repair atrioventricular valvular regurgitation or to relieve the right ventricular outflow tract (RVOT) or pulmonary arterial stenosis. One late death was due to aspiration pneumonia. Second reoperation was necessary for progressive worsening of left atrioventricular regurgitation and RVOT stenosis in one patient. Fourteen survived patients were followed up for a mean of 66.0 $\pm$ 26.7months and all of them w re NYHA functional class I or II.

Carinal resection is technically demanding and the surgical risk is relatively high. When tumor is confined around the carina, then lung parenchymal sparing surgery is technically feasible in selected cases. We performed carinal resection and reconstruction without pulmonary resection for a patient suffering with squamous cell carcinoma that involved the carina and this patient had undergone right upper lobectomy 19 months previously due to lung cancer.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular lesion that is characterized by proliferation of small to medium-sized vascular structures lined by histiocytoid or epithelioid endothelial cells and often accompanied by an inflammatory infiltrate comprising lymphocytes, plasma cells and eosinophils. A 34-year-old man without any generalized systemic conditions presented with a slowly enlarging painless swelling in the buccal area. An excisional biopsy was conducted and the diagnosis of Angiolymphoid hyperplasia with eosinophilia was confirmed. We report a case of angiolymphoid hyperplasia with eosinophilia of the buccal area in oral cavity and review the previously reported cases and literatures of angiolymphoid hyperplasia with eosinophilia.

Edwards Duromedics mechanical valve was introduced into clinical use in 1982 and is still being used today after several modifications. Valve-related complications after mechanical valve replacement are thiombo-embolism, endocarditis, valve malfunction, valve leaflet escape and fracture. Incidence of valve leaflet escape is very low. A 40 year-old male patient who had undergone mitral replacement with a 31mm Edwards Duromedics mechanical valve(model

A fifteen-year-old boy was transported to our hospital emmergency room due to sudden onset of chest pain, hemoptysis and dyspnea. He was diagnosed as persistent ductus arteriosus that had developed acute bacterial endocarditis with pulmonic valve vegetation and pulmonary embolism with pulmonary infarction. After conservative antibiotic therapy (vancomycin + aminoglycoside), we operated this patient successfully - patch closer of the ductus and pulmonary valve valvuloplasty - under the cardiopulmonary bypass.

Recently, The non-penetrating injury of bronchus has been increased, especially by traffic accident. Early diagnosis and primary repair of bronchial injury not only restore normal lung function but also avoid the difficulties and complications associated with delayed diagnosis and repair. This report describes about a case of total collapse and consolidation of left lung with the complete transection of nearly bifurcated portion of left main bronchus , lasted for 2weeks after traffic accident. This was diagnosed by fiberbronchoscopy and 3-D chest computed tomography(CT). She underwent the sleeve resection and end to end anastomosis, and postoperative PEEP for 2 days, suctioning twice by fiberbronchoscopy, continue postural drainge and physiotherapy were applied. She had almost full expansion of the left lung at discharge.

The main cause of ischemic heart disease combined with aortic valve disease is the systemic atherosclerotic process. Coronary artery embolism by a particle from the calcified aortic valvular tissue is very rare. A 73-year-old female patient was admitted due to chest tightness of recent onset. Two dimensional echocardiogram showed severe calcific aortic valve stenosis. Preoperative coronary angiogram exhibited a stenotic lesion at the distal right coronary artery, which seemed to be embolic in origin. The coronary embolus was removed through the coronary arteriotomy and then the arteriotomy site was repaired by onlay patch angioplasty technique. Aortic valve was replaced by a bioprosthetic valve. The embolus was reported as a fibrocalcified particle of diseased valve.

배경: 승포판 전엽이나 교련 또는 여러 판엽에 걸쳐 광범위한 병변으로 인한 승모판 역류의 경우 수술수기에 대한 뚜렷한 정립이 되어 있지 않은 실정이다. 최근 이러한 병변의 승모판 역류의 경우 PTEE(Polytetrafluro-ethylene)을 이용한 신건삭 형성술의 시행이 점차 늘고 있다. 이에 저자들은 PTEE를 이용한 신건삭 형성술이 승모판 성형술에 어떠한 영향을 미치는지 알아보고자 하였다. 대상 및 방법: 1994년 1월부터 1999년 12월까지 승모판막 성형술을 시행 받은 322명의 환자 중에서 신건삭 형성술을 이용하여 승모판 성형술을 시행한 144례(I군)과 신건삭 형성술 이외의 방법으로 승모판 성형술을 시행한 178례(II군)를 대상으로 하였다. 두 군에서 수술 직후ㅘ 수술 후 6개월, 1년 및 1년 단위로 주기적인 심초음파를 시행하였고 이를 통계적 검정하였다. 결과: 같은 기간 승모판 성형술은 승모판막 폐쇄 부전증으로 내원한 환자의 95%(306)에서 추적 관찰이 가능하였다. 두 구난에 수술 전 혈류 역학적인 차이를 보이지 않았고, 수술 전 평균 승모판막 폐쇄 부전의 정도는 I군이 3.8$\pm$0.4, II군이 3.6$\pm$0.3였으나 수술 후 추적 관찰에서 각각 1.3$\pm$0.9와 1.1$\pm$0.7 정도의 양호한 판막 성형술의 결과를 보였고 승모판막 면적의변화나 승모판막에서의 평균 압력차이 등 혈류 역학적인 결과에도 차이를 보이고 있지 않았다. 술 후 3명(0.9%)의 조기 사망과 4명 (1.2%)의 후기 사망이 있었으나 두 군간의 차이는 보이지 않았다. 만기 생존율( 93.7$\pm$3.3 vs 88.0$\pm$1.95) 및 판막살패가 발생하기 않을 확률( 93.7$\pm$3.6 vs 93.3$\pm$3.4%) 과 재수술이 필요치 않을 활률(99.3$\pm$0.7 vs 96.0$\pm$1.9%), 색전증, 감염성 심내막염, 판막과 관련된 합병증 발생률 등에서 두 군간에 의미 있는 차이는 없었다. 전엽과 후엽에서 신건삭 형성술을 시행한 환자에서는 통계학적인 차이가 없었다(p=0.29) 결론: 신건삭 형성술을 이용한 승모판 성형술은 승모판 성형술의 증가(r=0.98, p<0.01)를 가져 왔을 뿐만 아니라 내구성과 안정성에 있어 기존의 안전화된 수술 수기와 견줄만하다. 특히 이러한 신건삭 형성술은 승모판 전엽에 병변이 있는 경우와 교련부 및 여러 엽에 광범위한 병변으로 인하여 재건술이 어려운 경우에도 승모판 재건을 가능하게 하는 우수한 수술 수리가 사료된다.

Temporomandibular joint cysts usually occur between the second and fourth decade of life. There is a female predominance to male of approximately 3 to 1. The patients complain of swelling, pain and sometimes decreased mouth opening. Synovial cysts of the temporomandibular joint seem to develop by an increase of intraarticular pressure due to trauma or inflammation which causes capsular herniation. However, if inflammatory synovial cysts develop by an increase of synovial fluid into inflammation tissue in the capsule without capsular herniation, a differential diagnosis should include synovial chondromatosis and synovitis. This is a case report of a synovial cyst developed in a capsule of the temporomandibular joint.
