부분 폐정맥 환류 이상은 드문 선천성 폐정맥 기형의 한 종류로 진단 시 종종 간과될 수 있다. 대부분의 경우 비 침습적인 영상검사인 심장 초음파, CT 또는 MRI로 진단을 하게 되는데, 2D 모니터를 이용한 영상진단은 삼차원적으로 복잡한 심장의 구조를 이해하는데 제한이 있다. 최근에는 CT와 MRI에서 얻은 의료 영상 데이터를 기반으로 3D 프린팅 기술을 이용하여 심장의 모형을 만드는 기술이 소개되어 점차 이용이 증가되고 있다. 본 증례 보고에서 저자들은 우측 상 폐정맥과 우측 중 폐정맥이 상대정맥으로의 각각 배출되며 우측 중 폐정맥을 통해 양측 심방 간의 연결이 이루어진 환자의 CT 영상 및 3D 프린팅 모델에 대해 보고하고자 한다.

Purpose: This study was conducted to examine effects of a small group-based cardiocerebrovascular disease (CVD) prevention education program on knowledge, stage of change and health behavior among male bus drivers with CVD risk factors. Methods: A non-equivalent control group pretest-posttest design was used. Participants were 68 male bus drivers recruited from two urban bus companies. Participants from the two groups were selected by matching age, education and risk factors. Experimental group (n=34) received a small group-based CVD prevention education program 8 times over 6 weeks and 3 times through telephone interviews at 2-week intervals. Data were collected between December, 2010 and March, 2011, and were analyzed using chi-square test, t-test, and repeated measure analysis of variance with SPSS/Win18.0. Results: Experimental group showed significantly higher scores in CVD prevention knowledge (p<.001) and health behavior (p<.001) at 6 and 12 weeks after intervention. Participants in pre-contemplation and contemplation stages made progress to contemplation and action. This was significantly better at 6 and 12 weeks after intervention (p<.001). Conclusion: Results suggest that small group-based education programs for CVD prevention are effective in increasing knowledge, stage of change, and health behavior to prevent CVD among male bus drivers with CVD risk.

This study was conducted to investigate serum lipids and antioxidant vitamins status of male patients with cerebrovascular disease. The study consisted of 16 hospital patients(57.8$\pm$13.7 years) at 3 General Hospitals in Taegu who suffer from cerebrovascular disease and 21 healthy adults(55.5$\pm$7.2 years). The results were as follows: The systolic blood pressure of the patients(150.0$\pm$13.7mmHg) was sig nificantly higher than healthy control(126.0$\pm$17.4mmHg). In patients the percentages of drinking alcohol(more than 5 times/week) and smoking were also higher. And the patients had more stress than control. Total calorie, protein, carbohydrate, vitamin B1 and niacin intakes were significantly lower in the patients. The energy nutrients consumption reached the recommended level in all subjects who were investigated. HDL cholesterol(24.99 vs 37.86mg/dl) and vitamin E(12.94 vs 20.88mg/L) level showed significantly lower, but triglyceride level(175.50 vs 117.69mg/dl), total cholesterol/HDL cho lesterol(6.22 vs 4.39) and atherogenic index(5.22 vs 3.39) were significantly higher in the patient group. Therefore, it might be expected that refraining from drinking alcohol and smoking, and that having proper exercise and certain other healthy living habits which can decrease stress in addition suitable consumption of antioxidant vitamins can prevent the occurrence of cerebrovascular disease.

SPECT of regional cerebral blood flow was performed using $^{99m}Tc-HMPAO$ in 28 patients with cerebrovascular disease and quantitative analysis was done. Cerebral asymmetry index and percent index of asymmetry of cerebellar hemisphere of patients with cerebral infarction or ischemia were $0.764{\pm}0.576$ and $-5.6{\pm}7.1%$ and those of intracranial hemorrhage was $0.416{\pm}0.251$ and $-2.5{\pm}4.1%$ respectively. According to PIA of cerebellar hemisphere, 12 patients showed crossed cerebellar diaschisis. $^{99m}Tc-HMPAO$ SPECT seemed to be a useful tool for the evaluation of regional cerebral blood flow.

고혈압은 소아 청소년시기에 발생하는 흔한 만성질환 중 하나이다. 고혈압을 치료하지 않으면 여러가지 소아의 장기에 악영향을 미칠 수 있다. 여기서는 고혈압이 중추신경계에 미치는 영향에 대해 알아 보았다. 혈압의 변화에 따라 대뇌가 받는 영향은 다른 장기에 비해 덜 하다. 그것은 대뇌 자동 조절 기전때문이다. 즉 혈압의 변화에 따라 뇌혈관의 저항이 변하기 때문에 뇌혈류량이 일정하게 유지 된다. 그러나 이런 자동 조절 기전의 항상성이 파괴되면 급성으로 또는 만성으로 급성 고혈압 뇌병증, 허혈성, 출혈성 뇌경색, 학습 장애와 인지 기능 장애 등이 발생한다. 이에 고혈압이 대뇌에 미치는 영향에 대해 숙지하고 빠른 시일 내에 적절한 치료를 하면 이런 합병증을 예방할 수 있다.

뇌동맥류는 뇌혈관의 일부가 풍선처럼 부풀어나는 혈관계 질환이며 뇌동맥류의 파열은 사망이나 심각한 후유 장애를 야기한다. 뇌동맥류의 다양한 발생 원인 중 혈관 내부의 혈류의 유동이 중요한 인자로 의심된다. 뇌동맥류의 형성에 미치는 혈류역학적 인자를 규명하기 위해 내경동맥에서 발생한 환자의 내경 동맥류 CT 사진을 이용하여 내경동맥류 모델을 제작하고, 모델 내부의 혈류유동장을 입자영상속도계를 이용하여 측정하였다. 동맥류가 발생한 내경동맥류 모델에서는 동맥류 원위부 목(distal neck)쪽과 반대쪽 내경동맥 벽에서 전단응력이 높게 나타났다. 동맥류 발생에 미치는 혈류역학적 인자를 규명하기 위해 동맥류를 제거한 내경모델을 제작하여 맥동유동에서 내부 유동장을 측정하였다. 심실수축기 동안 휘어진 내경동맥의 바깥쪽 벽에서 혈류의 혈관벽 부딪힘이 관찰되었으며 심실이완기 초반에도 이는 계속 유지되었다. 내경 동맥 내부의 부차적 유동특성을 연구하기 위해 동맥류 발생 위치에서 혈관 축과 수직인 평면의 유동장이 측정되었다. 혈관 단면에서는 휘어진 혈관의 바깥쪽에서 안쪽으로 시계방향의 와류가 형성되었으며, 이로 인해 혈관벽 바깥쪽과 시계방향으로 90도 정도 지역에서 전단응력이 높게 나타났다. 혈류 유동 특성과 동맥류 발생위치를 비교해 보면, 혈류의 혈관벽 부딪힘이 관찰되는 위치와 부차적 유동에 의해 전단응력이 크게 나타난 지역은 동맥류의 발생위치와 일치하였다. 따라서 혈류의 혈관벽 부딪힘과 부차적 유동에 의한 전단력이 동맥류 발생의 혈류역학적 요인으로 의심된다.

Objectives : It has been reported that the presence of a pharmacologically inactive foreign substance, polystyrene latex bead, in subarachnoid space activates a non-specific immunological response and elicits arterial narrowing. Recently the activation of potassium($K^+$) channels may be of benefit in relieving cerebral vasospasm. The present study examined the effects of systemic administration of a ATP-sensitive $K^+$ channel activator, cromakalim, on the polystyrene latex bead-induced cerebral vasospasm. Methods : The spasm models similar to that caused by subarachnoid blood injection were created by injection of bead into rabbit cisterna magna. Intravenous injections of cromakalim were administered twice daily(bid) 30 minutes after induction of vasospasm. Animals were killed by perfusion-fixation 2 days after vasospasm. Basilar arteries were removed and sectioned, and the luminal cross-sectional areas were measured. Results : Injection of bead elicited an arterial constriction, reducing arterial diameter to 33.3% of resting tone. Cromakalim inhibited bead-induced constriction at a dose of 0.3mg/kg(Mann-Whitney test, p<0.01). Conclusion : These results support the concept that the cellular events triggered by inactivation of ATP-sensitive $K^+$ channels are responsible for the pathogenesis of vasospasm. The findings also indicate that cromakalim represents a potential therapeutic agents for the treatment of cerebral vasospasm.

Purpose: This study was designed to analyse economical efficiency of home care service by comparing a cost-effectiveness ratio(CER) between hospitalization and home care service. Method: The analytic framework of this study was constructed in 5 stages; perspective of the analysis, measurement of costs, measurement of effects, analysis of CER, and sensitivity analysis. The SAS program was utilized for the general characteristics of the subjects, descriptive statistics, homogeneous test, normality test and difference test. Result: The results were as follows; 1) CER was 35,248,256 of ADL, 7,996,026 of nursing satisfaction, 6,144,946,000 of QALY of patients in the hospital and 11,168,863 of ADL, 2,322,239 of nursing satisfaction, 3,674,556,000 of QALY of patients in the home care center. ICER was 438,067,932 of ADL, -190,044,176 of nursing satisfaction, 8,615,336,000 of QALY. 2) In the sensitivity analysis of sex, age and discount rate, the CER of patients in the home care center was lower than the CER of patients in the hospital. Conclusion: With these findings, it affirmed that home care service had an economical efficiency compared with hospitalization in cerebrovascular disease patients. Therefore, these results will be used to develop governmental policy or expansion of the home care service.
