Background: Immunologic and inflammatory responses of cardiopulmonary bypass(CPB) influence postoperative mortality and morbidity with multiple organ injury. It has been reported that ischemia/reperfusion induced-myocardial injury during CPB is causative of release of inflammatory cytokines such as interleukin-6(IL-6) and tumor necrosis factor-$\alpha$ (TNF-$\alpha$). The purpose of this study was to detect the time course of the activated cytokine and troponin-T(TnT), and to examine the correlation between such parameters during CPB. Material and Method: The serial samples were collected from arterial blood via radial arterial catheter in 23 patients who are underwent open heart surgery (OHS) with CPB, the IL-6, TNF-$\alpha$ and TnT were checked. Result: \circled1 IL-6, TNF$\alpha$- and TnT concentration increased significantly during CPB with a peaking level of CPB-off (p 0.05). \circled2 IL-6 had highly positive correlation with aortic cross clamping time and total bypass time(r=0.80, 0.78; p 0.05, respectively). \circled3 There was no correlation among IL-6, TNF-$\alpha$ and TnT. Conclusion: In conclusion, these data showed that elevated production of serum IL-6 during CPB was attributable to ischemia/reperfusion induced-myocardial damage. IL-6 will become a new and sensitive biological marker in assessment of myocardial damage during OHS with CPB. However, further studies will be needed to apply IL-6 in more patient population.

Alterations in the serum magnesium level were studied in twenty patients who had open-heart surgery during the period from August 1974 to May 1975. The patients were chosen at random. The operative procedures included repair for congenital heart diseases in fifteen patients and cardiac valve replacement for acquired valvular heart diseases in five patients. The age ranged from 8 to 46 years, with an average of 19 years. None of the patients had a history of gross neuromuscular abnormalities. Cardiopulmonary bypass was carried out using a roller pump and a disposable oxygenator. The prime solution consisted of 2 units of ACD banked blood and approximately an equal volume of non-blood additives in adults, while a relatively smaller volume was added in children. The average flow rate was 2,733 ml per minute. Blood samples for magnesium and arterial blood pH were obtained the day after admission 25 minutes after initiation of the bypass and on the morning the day after operation. Preoperative data were then compared with those obtained during the bypass and postoperatively by a paired test. During the bypass, the serum magnesium level decreased significantly from $1.425{\pm}0.029$ to $1.210{\pm}0.063mEq.$ liter (p<0.001). Also, there was a significant decrease in serum magnesium from $1.425{\pm}0.029$ preoperatively to $1.255{\pm}0.083mEq$. per liter (p<0.001). Also, there was a significant decrease in serum magnesium from $1.425{\pm}0.029$ preoperatively to $1.255{\pm}0.083mEq$. per liter postoperatively (p<0.01). The duration of bypass was less than 90 minutes in 10 patients (group A) and exceeded 90 minutes in the remaining 10 (group B). There was no statistical correlation between the groups A and B ($p{\gg}0.20$). Statistical analyses of the serum magnesium level and arterial blood pH showed no significant correlation with correlation coefficient; being -0.3485(pre-op), -0.2971(during bypass), and -0.1008(post-op), respectively. In all the patients, no gross neuromuscular abnormalities were found postoperatively. At present, the clinical significance of the serum magnesium level during and after bypass is controversial. In the near future, however, it is expected that improvements in prime solution and heart-lung machine will solve this problem.

배경: 관상동맥우회술에서 사용된 동맥 도관은 정맥 도관보다 우수한 장기 개존율을 보이며, 그에 따른 향상된 단기 및 장기 임상성적이 보고되어 있다. 또한, 심폐체외순환기를 사용하지 않고 시행하는 관상동맥우회술(Off pump coronary artery bypass grafting; Off pump CABG) 역시 기존의 심폐체외순환기를 사용하는 관상동맥우회술에 비해 좋은 수술성적이 보고되고 있다. 따라서 동맥 도관만을 이용한 Off pump CABG를 시행하면 보다 좋은 결과를 얻을 수 있을 것으로 생각하여, 저자들은 동맥 도관만을 이용하여 Off pump CABG을 시행한 환자들의 임상 결과를 분석하였다. 대상 및 방법: 2001년 1월부터 2004년 10월까지 Off pump CABG을 시행 받았던 630명의 환자 중 동맥 도관만을 사용하였던 325명을 대상으로 하였다. 대상 환자들의 수술 전 위험요인, 관상동맥질환의 정도 및 수술성적에 대해 조사하였다. 환자들의 평균 연령은 $59.3\pm11.9\;(36\~83)$세였고, 평균 좌심실박출계수는 $55.4\pm14.0\%\;(15\~86\%)$였다. 대상 환자의 $81.9\%$에서 삼혈관 질환, 또는 좌주관상동맥 질환을 보였다. 동맥을 사용하는 적응증은 좌전하행지는 협착이 $50\%$ 이상, 회선동맥 분지는 $80\%$ 이상, 우관상동맥은 $90\%$ 이상인 경우로 하였다. 수술 후 $7\~10$일에 총 194명의 환자에서 multi-slice 컴퓨터 단층촬영을 시행하여 동맥 이식편의 개존율을 조사하였다. 결과: 이용된 동맥 도관은 좌내흉동맥 322예($99.1\%$), 요골동맥 297예($91.4\%$), 우내흉동맥 157예($48.3\%$), 그리고 우위대망동맥 12예($3.7\%$)였다. 환자당 평균 $2.46\pm0.56$개의 동맥을 획득하여, 좌전하행지 329곳, 대각지 123곳, 변연둔각지 285곳, 그리고 우관상동맥 191곳 등 총 928곳에 문합하여, 환자당 평균 $2.86\pm0.78$개의 문합률을 보였다. 수술 후 사망은 1예($0.3\%$)였다. 수술 후 뇌경색은 없었으며 주요 합병증으로는 종격동염 6예($1.8\%$), 신부전증 4예($1.2\%$), 심근경색이 3예($0.9\%$), 그리고 출혈로 인한 재수술이 3예($0.9\%$) 있었다. 총 혈관 개존율은 $99.3\%$ (581/585)였고, 좌내흉동맥, 요골동맥, 우내흉동맥 및 우위대망동맥의 개존율은 각각 $100\%$(207/207), $99.2\%$(238/240), $98.5\%$(133/135) 및 $100\%$ (313)였다. 각각 두 개의 요골동맥과 우내흉동맥에서 부분협착이나 경쟁혈류가 관찰되었다. 결론: 동맥 도관만을 이용한 Off pump CABG를 시행하여 감염의 위험성을 증가시키지 않으면서 영구적인 신경학적 합병증을 일으키지 않았고 좋은 혈관 개존율을 보여주었다. 따라서 동맥 도관을 이용한 Off pump CABG는 관상동맥의 협착의 정도에 따라 효율적으로 시행 시 좋은 임상결과를 얻을 수 있을 것으로 생각된다.

Background: Redo coronary artery bypass grafting (CABG) is still associated with increased morbidity and mortality as compared to the first-time operation. Further, the application of the off-pump technique to redo CABG is limited due to technical difficulties. The aim of this retrospective study was to analyze early and midterm results after redo CABG and compare the outcome of redo on-pump and off-pump CABG. Methods: From June 1996 to October 2011, elective redo CABG was performed in 32 patients. Mean age was 64.8 years (on pump 64.3 years vs. off pump 65.5 years; p=0.658), and 21 patients were male. Among these patients, 14 (43.8%) underwent on-pump CABG, and 18 (56.2%) underwent off-pump CABG. Results: Internal thoracic artery was used in 22 patients (68.8%), and total arterial revascularization was achieved in 17 patients (53.1%). The average number of distal anastomoses was 2.13, and the rate of incomplete revascularization was 43.8%. The rate of total arterial revascularization was higher in the off-pump group (14.3% vs. 83.3%, p<0.001), and the use of saphenous vein graft was more in the on-pump group (78.6% vs. 16.7%, p<0.001). Overall hospital mortality was 3.1% (n=1) and was comparable in both groups (on pump 7.1% vs. off pump 0%; p=0.249). Postoperative complications occurred in 9 patients (64.2%), and the rate of complications was high in the on-pump group without statistical significance (64.2% vs. 33.3%, p=0.082). The mean follow-up duration was 5.4 years, and overall survival at 10 years was $86.0%{\pm}10.5%$. There was no significant difference in the 10-year survival rate between the two groups (79.6% vs. 100%, p=0.225). Conclusion: Redo CABG can be safely performed with acceptable mortality. Redo off-pump coronary artery bypass is feasible with low mortality and morbidity, comparable target vessel bypass grafting, and long-term survival. The off-pump technique might be considered a safe option for redo CABG in high-risk patients.

Chyloascities is an extravasation of milky chyle into the peritoneal cavity due to tumor , inflammation or rarely postoperative lymphatic trauma.It is an unusual complication that can lead to significant immunologic and nutritional consequences.We experienced one case of chyloascites after aorto-bifemoral bypass graft in a patient with aorto-iliac occlusive disease.The patient was a 62-year-old male, who suffered from severe progressive claudication for 5 months. A 16$\times$ 8mm gelsealed Dacron-Y shaped graft was used in arterial reconstruction. A bloody-milky fluid was drained through the operative wound from 3days after operation and evaluated biochemically.Diagnosis of chyloascites was made with repeated paracentesis and examination of the fluid.After Total parenteral nutrition[T.P.N] for 3 weeks from 6days after operation, chyloascites was controlled sufficiently and maintained a good graft-patency in abdominal sonogram.

The patient was 17 years old female who complained of coldness of right arm and occasional dizziness, since 4 months prior to admission. On physical examination, the right radial, brachial and common carotid arterial pulses were not palpable. Aortography revealed narrowing of innominate and right common carotid arteries, and complete obstruction of right subclavian artery. The right axillary artery was faintly visualized on the delayed film. Axillo-axillar bypass was done using Gore-Tex graft of 8 mm I.D.. By bilateral subclavicular incision, both side axillary arteries was exposed. End to side anastomosis was made between graft and right axillary artery and the graft was brought out to the left side, subcutaneously, over the sternum, and the anastomosis was made between graft and left axillary artery. Postoperatively, both radial pulses were equally palpable. On follow-up visiting, there were no subjective symptoms and blood pressure in both arms was equal.

Postoperative coronary arterial spasm is a rare but potentially fatal complication. A 51-year-old male patient with a history of a reactive ergonovine stress test coronary angiogram developed refractory coronary artery spasm after undergoing minimally invasive direct coronary artery bypass grafting of the left anterior descending coronary artery. The patient was successfully managed with rapid implementation of intra-aortic balloon-pump counter pulsation and extracorporeal membrane oxygenation.
