        결핵에 대한 폐절제술의 임상적 고찰

        김병열 대한흉부심장혈관외과학회 1983 Journal of Chest Surgery (J Chest Surg) Vol.16 No.3

        Pulmonary tuberculosis is still one of unsolved problems in Korea due to increased number of far-advanced and drug-resistant patients, who have poor pulmonary function. We have analyzed 1332 operated Gases during the period of 1958-1981. Annual incidence of the disease decreased from 110 [1960] to 21 [1980]. The ratio between male and female was 7:3 and the age of peak incidence was in the 3rd and 4th decades. Recently, patients below the age of 20 years were slightly decreased, but above 50 years were slightly increased. The patients consisted of far-advanced case in 60% and moderately-advanced in 39% in 1980, as compared with 40% and 59% correspondingly in 1965. Preoperative sputum positively decreased from 91% [1958-1963] to 43.8% [ 1974-1981 ]. Medically treated patients for more than 3 years increased from 16% [1958-1963] to 51% [1974-1981]. From the view of surgical indication, totally destroyed hung increased from 27% [1958-1963] to 4396 [1974-1981 ]. Therefore, pneumonectomy occupied 53.8% of total surgical management recently. Mode of surgical treatment showed that thoracoplasty [33%], resection [57%] in 1958-1963 and thoracoplasty [2%], resection [98%] in 1974-1981. As Semb`s thoracoplasty was the first choice of treatment until 1960, thereafter resection became the choice. Postoperative mortality increased from 1.6-2.096 to 396 recently as well as morbidity. It was mainly due to increased number of poor pulmonary function and postoperative spread of disease. On the basis of our experience, far-advanced and drug-resistant patients increased in number recently, whose pulmonary function was poor. So postoperative mortality and morbidity increased. Proper surgical intervention should be considered before the appearance of resistance for all chemotherapeutic drugs.

        관상동맥 협착증의 외과적 치험 -30례의 임상적 결과-

        김병열 대한흉부심장혈관외과학회 1995 Journal of Chest Surgery (J Chest Surg) Vol.28 No.11

        Thirty patients with ischemic heart disease underwent coronary artery bypass grafting [CABG from 1985 through 1994. There were 16 males and 14 females whose age ranged from 41 to 72 years old. Preoperative diagnoses were unstable angina in 13 of patients, stable angina in 8, postmyocardial infarction state in 7, and state of failed percutaneous transluminal coronary angioplasty [ PTCA in 2. The patterns of disease were single vessel involvement [ 17cases , double vessel involvement [ 7 cases , triple vessel involvement [ 3 cases , Lt main lesion including Lt. ostial lesion [ 3 cases . Saphenous vein grafts were used in 27/30 patients [ 90% , and internal mammary artery grafts were used in 6/30 patients [ 20% . The hospital mortality was 13.3% and all survivors were asymptomatic and improved over their preoperative status.

      • 血管增植巢와 血管腫의 內皮細胞內 Antihemophilic factor(F Ⅶ/vWF-Ag)의 免疫細胞化學的 檢索

        金丙烈,崔三任,金象皓 전북대학교 의과학연구소 1984 全北醫大論文集 Vol.8 No.2

        The clinical significan of factor Ⅷ/von Willebrand factor antigen(FⅧ/vWF-Ag) in various vascular lesions including vascular rumors and inflammatory reactive proliferation was investigated. FⅧ/vWF-Ag was detected in tissues of hyperplastic vessels in peptic ulcer, capillary hemangioma, cavernous hemangioma, hemangioerdothelioma, and hemangiopericytoma by means of peroxidase-antiperoxidase(PAP) method. The results were as follows. 1. Endothelial cells of hyperplastic vessels in peptic ulcer showed strong positive reaction. 2. Neoplastic endothelial cells in capillary hemangioma showed moderate to strong positive reaction, but the mesenchymal cells didn't show positive reaction. 3. Endothelial cells of dilated vessels in cavernous hemangioma and throm bus in the vascular lumen showed strong positive reaction, but the markedly attenuated cells and nectotic cells showed negative reaction. 4. Neoplastic cells in hemangioerdothelioma showed weak to moderate positive reaction. 5. Neoplastic cells in hemangiopericytoma showed negative reaction. According to these results, FⅧ/vWF-Ag was limited in the endothelial cells. And the degree of positivity depends on the degree of cellular differentiation. So the more differentiated cells show the stronger reaction. Detection of FⅧ/vWF-Ag by PAP method may be helpful in diagnosis of vascular endothelial lesions.

        Clinical Experiences of Multiple Organ Failure after Surgery for Acquired Cardiovascular Disease

        김병열 대한흉부심장혈관외과학회 1990 Journal of Chest Surgery (J Chest Surg) Vol.23 No.2

        A serious problem after cardiovascular surgery known as Multiple Organ Failure[MOF] whereby several vital organs successively demonstrate dysfunction in spite of intensive postoperative treatment has recently arisen. We have made a retrospective study of the clinical records of 137 patients who underwent cardiovascular surgery during past two years [1987-1988]. Fourteen patients [10%] developed multi-organ failure postoperatively with the results of seven death [50%]. In fatal group, preoperative poor cardiac function [Cardiac Index<2.0L/min/m2] was considered important prognostic factor and infection 5 disseminated intravascular coagulation complicating gastrointestinal bleeding were the leading cause of death. In conclusion, evaluation of multiple factors concerning multi-organ failure demonstrates preoperative poor functional preservation of vital organs is the main factor. So early diagnosis k management for each of the failing organs & prevention of infection are mandatory of the treatment of these critically ill patients.

        Carbomedics 기계판막 치환환자의 장기성적

        김병열,임용택,정승혁,강경훈,이정호 대한흉부심장혈관외과학회 2000 Journal of Chest Surgery (J Chest Surg) Vol.33 No.7

        Background; The aim of this study is to evaluate our clinical experience with the Carbomedics heart valve prosthesis. Material and Method; Between Aug. 1988 and Dec. 1998, 294 Carbomidics valves were implanted in 235 patients(mitral; 143, mitral and aortic; 59, aortic; 33) The mean age at operation is 40.0$\pm$12.3 years(range 7 to 68 years); 63.8% (150patients) were woman. Follow up was 97.4% complete and mean follow up time was 5.7years with a total of 1209.2 patient-years. Result; The hospital mortality was 8.9%(mitral; was 95.2$\pm$1.6%(mitral ; 94.9$\pm$2.1%, mitral and aortic 95.0$\pm$3.7%, aortic 96.2$\pm$3.8%). Actual freedom rates from complications(linearized rates in parentheses) were fllowings; thromboembolism 96.2$\pm$1.5%(0.59%pt-yr), valve thrombosis 96.7$\pm$1.4%(0.5%/pt/yr), anticoagulant related hemorrhage 98.3$\pm$1.0%(0.25%/pt-yr), perivalvular leak 99.0$\pm$1.4%(0.5%/pt-yr), endocarditis 98.7$\pm$1.0%(0.25%/pt-yr), perivalvular leak 99.0$\pm$0.7%(0.17%pt-yr), endocarditis 98.7$\pm$1.0%(0.17%$\pm$pt-yr) and overall valve-related complications 88.9$\pm$2.5%(1.68%/pt-yr). Conclusion; The clinical performance of the Carbomedics valve was quite satisfactory with a low incidence of valve related mortality and morbidity. 배경; Carbomedics 기계판막은 보편적으로 많이 이용되는 기계판막의 일종이며 국립의료원에서는 1988년부터 이것을 사용하여 왔다. 저자들은 1994년에 중단기 성적을 흉부외과 학회지에 보고한바 있으며 이번에 10년 임상성적을 보고하고자 한다. 대상 및 방법 ; 1988년 8월부터 1998년 12월 RK지 Crbomedics 판막을 이용하여 판막치환술을 받은 235명의 연속적인 환자를 대상으로 하였으며 승모판막 치환 143예, 승모판막 및 대동맥판막치환 59예, 대동맥 판막치환 33예이었다. 평균 연령은 40세 이었으며 남녀의 성비는 85;150으로 여성환자가 원등하게 많았다. 임상추적 종료시점은 1999년 6월로 정했으며 추적율은 9704% 이었다. 전체 추적 기간은 1209.2환자-년이었고 평균 5.7년이었다. 결과; 조기 사망류은 8.9%, 만기 사망률은 4.7%로 전체사망율은 13.1%(31명/235명)이었다. 10년 생존율은 95.2$\pm$1.6%이었다. (승모판막치환; 94.9$\pm$2.1%, 승모판막 및 대동맥판막치환; 95.0$\pm$3.7%, 대동맥판막치환; 96.2$\pm$3.8%). 판막관련 합병증 중 혈전전색증, 판막혈전폐쇄증, 항응고제 관련 출혈, 판막주위 누출, 심내막염등의 linearized incidencesns 각각 환자-년당 0.59%, 0.5%, 0.25%, 0.17%, 0.17%였으며 혈전전색증이 없을 확률은 96.2$\pm$1.5%, 판막폐쇄증이 없을 확률은 96.7$\pm$1.4%, 항응고제관련 출혈이 없을 확률은 98.7$\pm$1.0%이었고 전체 판막관련 합병증이 없을 확률은 88.9$\pm$2.5%이었다. 결론; 장기 추적검사에서 Carbomedics 판막은 판막과 관련된 합병증 및 사망률이 낮았다.
