Anomalous drainage of the right superior vena cava into the left atrium is a very rare congenital cardiac anomaly. Recently a patient with this venous anomaly was surgically corrected and forms the basis of this report. Patient findings were as follows: The patient has no other symptom but cyanosis which prompted cardiac evaluation Chest PA and electrocariogram were usual. Cross-sectional echocardiogram showed normally connected heart without intracardiac defect, Inferior vena cava drained normally into right atrium and coronary sinus was not dilated. Contrast, given into the right atrium, appeared in the left atrium This rare venous anomaly was confirmed by surgery. Surgical correction consisted of division of superior vena cava above the junction of left atrium and reanastomosis into right atrial appendage. Postoperative digital subtracion angiography confirmed the successful repair. She has doing well for 6months since operation. Systemic venous anomalies without intracardiac defect are very rare. However this anomalies should be considered in the differential diagnosis of cyanosis. The successfully corrected case is reported and literature is reviewed.

From May 1988 to June 1994, )73 patients underwent exploratory thoracotomy for resection of non- small cell lung cancer, and 48 patients staged pathologically as lIIB were analyzed. 74 lesions were involvement of great vessel (n=26), heart (n=5), ipsilateral lung metastasis(n=4), esophagus (n=4), carina(n=3), mediastinum (n=2), trachea(n=1), spine (n=1) and 13lourO seeding(A=15). N3 lesions were involved in 6 patients. Extended pulmonary resection with radical mediastinal node dissection was possible in 25 patients, and exploration only was performed in 23 patients. The most frequent cause of unresectability was pleural seeding. Postoperative morbidity was )2 % (8125) and mortality was 16 % (41 25) in resected group. The adjutant therapy was given to 37 patients. The 1 year and 3 year survival for resected group ncluding operative deaths was 57.2%, and 2).8 % (median 15 months), but 48.4%, and 0 % (median 7 months) for exploration only group (Log-Rank test, p : 0.17). Our results suggest that extended pulmonary resection might be helpful for carefully selected patients with 74 non-small cell lung cancer, but meticulous preoperative work-up for staging, especially to detect pleural seeding and Invasion to the irlediastinal structures is a prerequisite to avoid unnecessary thoracotomy. 원자력병원에서는 1988년 5월부터 1994년 6월까지 373명의 비소세포 폐암 환자를 개흥하였으며, 이 중 병 리 학적 병기 lIIB로 판명된 48명의 겨록을 분석하였다. 74 병소는 대 혈관(26례), 심장(5례), 동측폐 전이 (4ET ), 식도(4El ), 기관 분기를(3례), 종격동(2례), 기관(1례), 및 척추 체부(1례) 등의 침범과 늑막 파종(늑막 전이, 15례)이었다. 수술은 48명중 25명에서 확대 폐절제및 림프절 절제를 시행하였으나, 23 례 에서는 시험 개흥술만 시행하였으며, 가장 흔한 절제 불가능의 원인은 늑막 파종이 었다. 절제 군의 수 술 유병률과 사망률은 각각 32 % (8125), 16 % (4125)이었고, 시험 개흥술 군에서는 각각 4% (1123), 0% (0123)이었다 수술 후 대부분의 환자에서 (37148) 항암 치료 또는 방사선 치료 등의 보조요법을 병 행하였 다. 수숲 후 1년 및 3년 생존률은 수술 사망을 포함하여 절제 군에서는 각각 57.2%, 23.8 % (중앙값, 15개 횡)이 었으며, 시험 개흥군에서는 각각 48.4%, 0 % (중앙값, 7개 월)이 었다(Log-Rank test, p = 0.17). 이상의 결과로,74환자의 일부에서 확대 폐절제의 역할이 인정 된다고 할 수 있으나 수술의 위험성 이 높으므 \ulcorner환자의 선택에 신중을 기해야 하며, 불필요한 개흥을 피하기 위해서는 늑막 파종과 종격동 구조물의 침습을수술전에 발견하기 위한보다 정교한 진단 및 병기 결정 과정이 요구된다.

Pancreatitis is a known complication of cardiac surgery with cardiopulmonary bypass. Although ischemia is believed to be a factor, the exact cause of pancreatitis after cardiopulmonary bypass remains unknown.We prospectively studied 67 consecutive patients undergoing cardiac surgery with cardiopulmonary bypass for evaluation of the pancreatic injury after cardiopulmonary bypas. Serial measurement of amylase level in serum and urine was done postoperatively. Hyperamylasemia was detected in 15 patients[22.4% , of whom no patient had pancreatitis. There was no significant difference between serum amylase level and parameters such as cardiopulmonay bypass time, aortic cross clamp time, mean blood pressure, rectal temperature, flow rate, and use of circulatory arrest during cardiopulmonary bypass. Hyperamylasuria was detected in 8 patients[11.9% , and urine amylase level was elevated significantly in the groups with prolonged cardiopulmonary bypass, mean blood pressure more than 40mmHg, and rectal temperature more than 20 $^{\circ}$C. We recommend that serum amylase level and/or amylase-creatinine clearance ratio is measured for ealy detection and management of pancreatitis after cardiopulmonary bypass.

Ebstein`s anomaly 이외의 격리성 원발성 삼천판 부전증[isolated primary tricuspid insufficiency]의 수술 치험 2례

백희종,안혁,Baik, Hee-Jong,Ahn, Hyuk 대한흉부심장혈관외과학회 1991 Journal of Chest Surgery (J Chest Surg) Vol.24 No.9

Isolated primary tricuspid insufficiency except Ebstein`s anomaly is rare disease. Recently we experienced two cases of isolated primary tricuspid insufficiency and treated successfully with annuloplasty or valve replacement. We could not classify our case as one of the classification of isolated tricuspid insufficiency, because the morphology and microscopic finding did not suggest any similar variety.

Between Jan. 1986 and Aug. 1992. 72 patients underwent Rastelli procedure. There were 43 male and 29 female, aged 46 days to 16 years [mean age, 5.2 years] with 18 patients less than 2 years of age. All patients had complex defect, 27 pulmonary atresia with ventricular septal defect, 18 corrected transposition of great arteries with pulmonary atresia or punmonary stenosis, 10 truncus arteriosus, 10 double outlet right ventricle with pulmonary atresia or stenosis, 7 complete transposition of great artersia with pulmonary atresia or pulmonary stenosis. The types of extracardiac valved conduit used were prosthetic valve[n=47, 24 car-bomedics, 19 Ionescu-Shiley, 4 Bjork-shiley] and hand-made trileaflet valve using pericardium. [n=23, 20 bovine pericardium, Z autologous pericardium, 1 equine pericardium] The mean size of valved cinduit was 5.25mm larger in diameter than the size of main pulmonary artery. [normalized to the patient`s body surface area] There were 17 hospital death[24%] and 4 late deaths[5.6%]. Postoperative complication rate was 38.9%a, none of which was conduit-related. All patients were followed pos-toperatively for 1 to 73 months. [mean 25.8 months] During follow-up period, reoperation was done in 6 patients due to stenosis of valved conduit. Mean interval between intial repair and reoperation was 20.3 months. In our experience, li recently extracardaic valved conduits between right ventricle [or pulmonary ventricle] and pulmonary artery were inserted with increasing frequency in infants less than 2 year, but hospital mortality was decreased, 2] Risk of reoperation due to conduit stenosis is low, so that the effect of graft failure on overall survival is minimized. 3] Nevertheless, because any type of extracardaic valved conduit is not ideal in children, we recommended that Lecompte should be done if cardiac anatomy is permitted.

Vidio-assisted thoracic surgery[VATS] has recently evolved as an alternative to thoracotomy for several thoracic disorders,and the role of thoracoscopy has expanded with advances in surgical techniques and instruments. From May 1993 to May 1994, 13 patients with mediastinal mass underwent VATS for diagnosis and treatment at Gil General Hospital. There were four males and nine females, and their ages raged from 5 years to 66 years with average 38.8 years. Among 13 patients, 3 were operated for tissue diagnosis,9 for treatment,and 1 for diagnosis and treatment. Pathologic diagnoses were as follows; 5 benign neurogenic tumors, 2 thymoma, 2 sarcoidosis, 1 teratoma, 1 peripheral neuroepithelioma, 1 tbc lymphadenitis, and 1 pericardial cyst. The mean time of operation was 111.7 $\pm$ 30.7 minutes[60-160], mean duration of chest tube drainage was 2.9 $\pm$1.9days[1-9], mean hospital stay was 6.2 $\pm$2.6 days[4-13]. There was no patient needed blood transfusion or conversion to open thoracotomy. Accurate diagnosis was possible in all patients operated for diagnosis and /or treatment.[4/4,100%] Two complications occurred in two patients: 1 transient Horner,s syndrome,1 anhydrosis of left arm. Compared with those of conventional thoracotomy done for mediastinal mass during previous 2 years[May 1991 - April 1993], operative results of VATS were better in all aspects. For mediastinal mass, we concluded that VATS can be done with less morbidity,less complication,less blood loss,shorter operation time and hospital stay,and not more expensive in cost than conventional thoracotomy. Noticeably, we think that VATS is the operation of choice for the diagnosis and palliation of malignant mediastinal mass.

비소세포폐암 환자의 국소 림프절 전이 발견을 위한 FDG PET의 이용

백희종,박종호,최창운,임상무,최두환,조경자,원경준,조재일 대한흉부심장혈관외과학회 1999 Journal of Chest Surgery (J Chest Surg) Vol.32 No.10

Background: Positron emission tomography(PEFT) using fluorine-18 deoxyglucose(FDG), showing increased FDG uptake and retention in malignant cells, has been proven to be useful in differentiating malignant from benign tissues. We indertook the prospective study to compare the accuracy of the whole-body FDG PET with that of the conventional chest computed tomography(CT) for nodal staging of non-small-cell lung cancers(NSCLC). Material and Method: FDG PET and contrast enhanced CT were performed in 36 patients with potentially resectable NSCLC. Each Imaging study was evaluated independently, and nodal stations were localized according to the AJCC regional lymph nodes mapping system. Extensive lymph node dissection(1101 nodes) of ipsi- and contralateral mediastinal nodal stations was performed at thoracotomy and/or mediastinoscopy. Image findings were compared with the histopathologic staging results and were analyzed with the McNema test(p) and Kappa value(k). Result: The sensitivity, specificity, positive predictive value, and negative predictive value of CT for ipsilateral mediastinal nodal staging were 38%, 68%, 25%, 79%, and 61%, and those of PET were 88%, 71%, 47%, 95%, and 75%(p>0.05, K=0.29). When analyzed by individual nodal group(superior, aortopulmonary window, and inferior), the sensitivity, specificity, positive predictive value, and negative predictive value of CT were 27%, 82%, 22%, 85%, and 73%, and those of PET were 60%, 87%, 92%, and 82%(p<0.05, k=0.27). Conclusion: FDG PET in addition to CT appears to be superior to CT alone for mediastinal staging of non-small cell lung cancers.
