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.

Coronary ostium obstruction due to dislodgement of the prosthetic valve is a rare and life-threatening complication, and particular caution is required for sutureless aortic valve replacement (AVR) with concomitant valvular surgery. In general, coronary artery bypass surgery is performed when coronary ostium obstruction occurs after AVR, but other options may need to be considered in some cases. Herein, we present a case of coronary artery occlusion in an 82-year-old female patient who had undergone AVR and mitral valve replacement for aortic valve stenosis and mitral valve stenosis at the age of 77 years. A hybrid procedure involving redo AVR and percutaneous coronary intervention after left main coronary ostium endarterectomy was performed. To summarize, we present a case of hybrid AVR in a patient with coronary artery obstruction after AVR that was successfully managed using this method.

배경: 그간 관상동맥 우회수술후의 관상동맥 조영술 결과는 주로 우회도관의 개존률에 초점을 맞추어 보고되어 왔다. 그러나 수술후의 관상동맥 조영술 검사로부터 얻을 수 있는 유용한 정보의 폭은 훨씬 넓으며, 이는 수술 전략 설정에 큰 도움을 줄 수 있으리라 생각된다. 대상 및 방법: 1994년 11월부터 1999년 3월까지 관상동맥 우회수술을 시행받고 퇴원한 환자 448명중 1개월 이상 경과후 관상동맥 조영술 추적이 이루어진 73명을 대상으로 하였다. 수술후 평균 10.6개월 경과시 관상동맥 조영술 검사가 시행되었고 검사 이유는 협심증의 잔존이나 재발이 54명, 심근관류검사나 초음파검사상의 이상이 13명, 단순한 추적목적이 6명이었다. 결과: 우회도관 개존률은 단순추적검사 환자들에서는 80.9%(내흉동맥 100%, 복재정맥 75.0%), 심근 허혈이 있는 것으로 판단된 환자들에서는 61.6%(내흉동맥 81.1%, 복재정맥 55.3%)였다. 50명(68.5%)의 환자에서 우회도관 조성 근위부의 관상동맥 내경협착이 20% 이상 진행한 곳이 한 군데 이상 나타났다. 수술 전 완전 폐쇄되지 않았던 201개의 관상동맥 분지중 95개(47.3%)에서 협착 정도가 20%이상 진행하였고 이중 64개(31.8%)는 완전 폐쇄로 진행하였다. 협착이 진행하는 빈도는 수술후 경과한 시간이나 수술전의 협착정도와는 연관이 없었고 우회도관이 폐쇄된 경우(36.3%)보다 개통되어 있는 상태(56.5%)에서 더 높게 나타났다(p<0.05). 내흉동맥과 복재정맥의 비교시 개존률(83.3% vs 56.6%) 뿐만 아니라 경피적 중재술이 필요한 경우 성공적으로 시행될 확률도 큰 차이를 보였다(100% vs 62%, p<0.05). 결론: 관상동맥 우회술 후 비교적 조기에 우회도관 조성 근위부의 관상동맥 협착이 진행하는 빈도가 상당히 높은 것으로 나타난 만큼 복재정맥의 불량한 장기 개존률을 고려할 때 중등도 이하의 협착을 가진 관상동맥 분지의 우회로 조성에는 신중을 기할 필요가 있다고 판단된다. 또한 본 연구 결과 관상동맥 우회수술시 좌전하행지 우회로의 중요성과 함께 내흉동맥의 우수성을 확인할 수 있었다.

동맥편만을 이용한 관상동맥 우회술을 위한 한 방법으로 양측성 내흉동맥을 이용한 관상동맥우회술의 유용성에 대해 알아보고자 하였다. 대상 및 방법: 2000년 1월부터 2001년 12월까지 서울아산병원 흉부외과에서 심폐바이패스를 사용하지 않는 관상동맥 우회술을 시행받은 139명의 환자를 대상으로 의무기록을 이용한 후향적 분석을 시행하였다. 전체환자를 양측성 내흉동맥을 사용한 환자군을 양측 내흉동맥군(bilateral internal thoracic artery; BITA group, n=85), 단일 내흉동맥을 사용한 환자군을 단일 내흉동맥군(single internal thoracic artery; SITA group, n=54)으로 나누었고 수술결과를 비교하였다. 결과: 수술에 따른 사망은 양 군에서 각각 1예씩 발생하였다. 중환자실 재원일 및 퇴원기간은 양 군 간에 차이를 보이지 않았다(BITA군: 2.4$\pm$1.7일, 11.2$\pm$17.7일, SITA군 2.8$\pm$2.7일, 9.7$\pm$7.1일, p>0.05). 문합혈관수는 BITA군이 3.9$\pm$0.7개, SITA군이 3.1$\pm$0.8개로 BITA군이 더 많았다. 술 후 심근경색은 7예(BITA군 2예, SITA군 5예)에서 발생하였고 심부 흉골감염이 4예(BITA군 3예, SITA군 1예)발생하여 재수술이 시행되었다. 수술 직후 104명의 환자에서(BITA군 64/85, SITA군 40/54명) 관상동맥 조영술이 시행되었고 좌전하행지로의 문합부위 협착이 4예(BITA군: 2예, SITA군: 2예)에서 관찰되었다. 전체 관찰기간 동안의 문합부위 협착 발생은 총 8예였고 이 중 3명의 환자에서 경피적 관상동맥 성형술이 시행되었으며 관상동맥 우회술을 재시행한 경우는 얼었다. 걸론: 관상동맥 우회술 시행시 양측 내흉동맥의 사용은 수술 전후 이환율에서 큰 차이 없이 만족할 만한 개통률을 얻으면서 동맥편만을 이용한 관상동맥 우회술을 가능케 하는 유용한 대안이 될 수 있으리라 생각한다.

Purpose: The purpose of this study was to identify the level of quality of life and gender differences in predictors of quality of life among patients with coronary artery disease. Methods: Participants for this descriptive survey were 67 men and 65 women who signed informed consents. They were patients who had undergone coronary artery bypass graft surgery or percutaneous transluminal coronary angioplasty, or were on medication therapy after a heart attack. The Short-Form Health Survey (SF-36), Personal Resource Questionnaire-part (II), and the Center for Epidemiologic Studies Depression Scale were used to measure quality of life, social support, and depression respectively. Gender and age were controlled because they were reported as influencing factors in previous studies. Results: There were significant differences in depression and quality of life between men and women however, social support was not significantly different by gender. In multiple regression analysis, depression was a significant predictor and explained 51.9% of quality of life for men. In women, depression and social support were significant predictors and explained 50.9% of quality of life. Conclusion: Factors influencing quality of life for men and women were different, and therefore, nurses need to consider their patients' gender and use specific strategies to improve quality of life for patients with coronary artery disease.

Objectives: We aimed to evaluate the effect of geographic units of analysis on measuring geographic variation in medical services utilization. For this purpose, we compared geographic variations in the rates of eight major procedures in administrative units (districts) and new areal units organized based on the actual health care use of the population in Korea. Methods: To compare geographic variation in geographic units of analysis, we calculated the age-sex standardized rates of eight major procedures (coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, surgery after hip fracture, knee-replacement surgery, caesarean section, hysterectomy, computed tomography scan, and magnetic resonance imaging scan) from the National Health Insurance database in Korea for the 2013 period. Using the coefficient of variation, the extremal quotient, and the systematic component of variation, we measured geographic variation for these eight procedures in districts and new areal units. Results: Compared with districts, new areal units showed a reduction in geographic variation. Extremal quotients and inter-decile ratios for the eight procedures were lower in new areal units. While the coefficient of variation was lower for most procedures in new areal units, the pattern of change of the systematic component of variation between districts and new areal units differed among procedures. Conclusions: Geographic variation in medical service utilization could vary according to the geographic unit of analysis. To determine how geographic characteristics such as population size and number of geographic units affect geographic variation, further studies are needed.

Objectives: The accurate measurement of geographic patterns of health care utilization is a prerequisite for the study of geographic variations in health care utilization. While several measures have been developed to measure how accurately geographic units reflect the health care utilization patterns of residents, they have been only applied to hospitalization and need further evaluation. This study aimed to evaluate geographic indices describing health care utilization. Methods: We measured the utilization rate and four health care utilization indices (localization index, outflow index, inflow index, and net patient flow) for eight major procedures (coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, surgery after hip fracture, knee replacement surgery, caesarean sections, hysterectomy, computed tomography scans, and magnetic resonance imaging scans) according to three levels of geographic units in Korea. Data were obtained from the National Health Insurance database in Korea. We evaluated the associations among the health care utilization indices and the utilization rates. Results: In higher-level geographic units, the localization index tended to be high, while the inflow index and outflow index were lower. The indices showed different patterns depending on the procedure. A strong negative correlation between the localization index and the outflow index was observed for all procedures. Net patient flow showed a moderate positive correlation with the localization index and the inflow index. Conclusions: Health care utilization indices can be used as a proxy to describe the utilization pattern of a procedure in a geographic unit.

PURPOSE: The purpose of this study is to understand the difference in the risk factors of coronary artery disease (CAD) between Korean and American CAD patients to determine the discriminant factor for each group, as well as to provide useful information to be reflected in the national concern of health. METHODS: Data were collected from 248 Korean and 107 American CAD patients who underwent either percutaneous coronary intervention or coronary artery bypass grafting. By using t-test and $X^2$-test, risk factors were compared between the Koreans and Americans. To elucidate which risk factor was the most discriminant for each group, logistic regression analysis was performed. RESULTS: All risk factors, except diastolic blood pressure, showed a significant difference between the two groups. $X^2$-test showed statistical significance with respect to the smoking rate between the female groups. Moreover, there was a statistically significant difference between the two groups regarding blood total cholesterol (TC) and triglyceride, and between the male groups, here was a statistically significant difference with respect to blood high-density lipoprotein cholesterol (HDL). Diabetes mellitus (DM) was the most discriminant factor for Korean patients while TC/HDL is the most discriminant for the Americans. CONCLUSION: The characteristics of CAD risk factors were determined to be different between Koreans and Americans in this study. TC/HDL was a discriminant factor for Americans while DM was a discriminant factor for Koreans. This result implies that DM should primarily be given attention to prevent CAD in Korean adults.
