In the last few years there has been a resurgenceof interest in in-situ saphenous vein arterial bypass for lower extremity revascularization because of improved patency rates. we performed 1 in situ bypass oreration using the intraluminal valve-disruption tecnique. A 65-year-old female who had ztherosclerotic obstruction in the superficial and popliteal arteries underwent in situ saphenous vein arterial bypass. After harvesting of saphenous vein, we used LeMaitre retrograde valvulotome for valve-disruption technique. Completion of the arterrigraphy was performed to evaluate bothh the anastomoses. The two side brances were all ligated. In situ saphenous vein arterial bypass has become the procedure of choice for distal reconstruction in severely ischemic lower extremities because of improved long-term patency compared with reversed-saphenous vein bypass procedure.

Arterial bypass for the chronic ischemia of the lower extremities underlying atherosclerotic obliterans has been performed with a number of alternative conduits from 1941 by Kunlin. It is indicated for the limb salvage of patients with threatened limb loss despite of several controversies in surgical treatment of atherosclerotic obliterans. From March 1991 to January 1995, 26 arterial bypasses were performed in 23 patients with the chronic ischemia of the lower extremities in our hospital. Their mean follow up period is 18.9 months ranging from 4 months to 44 months. Mean age is 60.9 years ranging 47 years to 76 years and the most prevalent incidence is the 6th decade. 21 patients are male and 2 patients are female. 19 of 23 patients are smokers. Clinical classifications by Fontaine are class II[21.7% , class III[34.8% and class IV[43.5% .Diabetes mellitus[47.8% , hypertension[43.5% , hyperlipid-emia[26% , tuberculosis[21.7% , cerebrovascular accident[13.0% and cardiac diseases[8.7% are associated. Aorto-single femoral bypass in 4 cases, aorto-bifemoral bypass in 5 cases, aortofemoral & femoropopliteal bypass in 2 cases, femoropopliteal bypass in 10 cases, popliteotibial bypass in 3 cases, femoropedal bypass[composite graft bypass in 2 cases were surgically approached. There are complicated early thrombosis in 4 cases those are required immediately reoperation, wound infection in 3 cases, hematoma in 3 cases, and so on. Postoperative complication rate is 53.8%.Postoperative patency rates are 84.6% at 6 months, 75.0% at 1 year, 70.0% at 2 years and 66.7% at 3 years. We usually used 6 mm & 8 mm graft for bypass, and the rate of thrombosis formation is 28.6%[2/7 in 6 mm graft and 12.5%[2/16 in 8 mm separately. In according to the graft materials, the rate of thrombosis formation is higher in the group using artificial graft than in that using autologous saphenous vein[16.6% vs 12.5% . Limb salvage rate is 76.9%. Postoperative mortality rate is zero %.

After the real birth of vascular surgery occurred with the introduction of the first practical arterial prosthesis about 50 years ago, a variety of potential vascular graft had been tested and rejected. Polytetrafluoroethylene [Teflon, PTFE] was first used as a vascular prosthesis in 1957. Thereafter this pros-thesis was first used clinically in 1972 and has subsequently been widely applied as a small and medium sized vessel replacement because it is easy to use and readily available. There are numerous reports of good results about Polytetrafluoroethylene graft. We experienced the three cases of arterial bypass graft using polytetrafluoroethylene vascular pros-thesis. First, 21 years old female patient had suffered from Takayasus disease which affected the left subclavian artery and right subclavian-left axillary extra anatomical bypass graft as done. Second, 64 years old male patient had suffered from Leriche syndrome for 12 years and the left axillofemoral and femorofemoral extra anatomical bypass graft was done. Third, 34 years old male patient had suffered from recurrent Buergers disease which affected the left popliteal artery and the isolated popliteal artery segment bypass graft was done. Relatively satisfactory result was obtained in early post-operative period in all three cases.

Arterial thoracic outlet syndrome (TOS) causes ischemic symptoms; it is the rarest type, occurring in 5% of all TOS cases. This paper is a case report of a 38-year-old male patient diagnosed with arterial TOS, displaying symptoms of acute critical limb ischemia caused by thromboembolism. Brachial artery of the patient has been diffusely damaged by repeated occurrence of thromboembolism. It was thought to be not enough only decompression of subclavian artery to relieve the symptoms of hand ischemia; therefore, bypass surgery using reversed great saphenous vein was performed.

The Saphenous vein is still the graft of choice for bypass of small calibered peripheral arteries, and many recent studies revealed that the "In Situ" technique had higher rate of long term patency than the conventional "reversed" one. A 71-year-old male who had atherosclerotic obstruction in the superficial femoral and popliteal trifurcation underwent In Situ saphenous vein arterial bypass. The saphenous vein is exposed by a long medial skin incision over the course of the vein. All branches of vein are ligated. A olive-tipped metal needle is introduced into the vein from above and everts the valves. The patient has been followed for 2 months after operation. The graft remained pulsatile and the gangrenous areas on the toe proceeded to heal. We think In situ vein bypass offers an excellent and safe method of revascularization of the arterial occlusion below the knee although it is technically demanding and the time consuming. time consuming.

Coronary artery bypass grafting (CABG) is rarely performed in infants because of its technical difficulty and unclear long-term results. A 90-day-old male infant weighing 3.5 kg who underwent an arterial switch operation (ASO) for transposition of the great arteries developed left coronary artery insufficiency despite augmentation and reimplantation of the left coronary button. On-pump beating heart CABG was performed using an internal mammary artery graft to revascularize the left anterior descending artery. Postoperative computed tomography angiography revealed that the graft was patent. At 7 months postoperatively, the patient weighed 8.5 kg, and echocardiography revealed good ventricular function. CABG can be an alternative treatment for post-ASO coronary complications in early infancy.

배경: 죽상동맥경화성 하지동맥폐쇄증은 대부분의 경우에 전신 동맥 경화증이 동반되며 사망의 원인으로는 주로 반 이상이 관상동맥질환에 의하여 발생한다. 또한 만성 동맥폐쇄증 수술 후 수술 사망 원인은 심장 합병증에 의한 사망이 가장 빈번한 것으로 알려져 있다. 특히 죽상동맥경화성 하지동맥폐쇄증 환자에게 과거에 심질환이 없거나 허혈성 심질환의 주증상이 없던 경우에 수술 후 높은 사망률을 보이는데 이런 이유로 이 환자군에 대한 관상동맥질환의 동반 여부에 대한 수술 전 검사의 필요성이 제기되는 바이다. 대상 및 방법: 2001년 2월부터 2004년 10월까지 죽상동맥경화성 하지동맥폐쇄증으로 입원한 환자 중 과거력상 심질환이 있었거나 허혈성 심질환이 주증상이었던 환자를 제외한 52명의 환자를 대상으로 관상동맥조영술과 하지동맥조영술을 동시에 시행하여 죽상동맥경화성 하지동맥폐쇄증에서 관상동맥질환의 동반 빈도를 파악하였다. 또한 죽상동맥경화성 하지동맥폐쇄증의 중증도를 나타내는 AVO score와 동반된 관상동맥질환과의 상관관계를 비교하였다. 결과: 죽상동맥경화성 하지동맥폐쇄증에서 관상동맥질환을 동반한 경우는 63%(33명)였고, 고령, 당뇨, 고혈압, 흡연력, 고콜레스테롤혈증 등의 동맥 경화증의 위험인자 중 고령과 고혈압이 관상동맥 질환을 동반하는 죽상동맥경화성 하지동맥폐쇄증의 중증도와 통계학적인 의미를 보였다. AVO score가 높을수록 관상동맥 질환의 동반이 흔하였고 관상동맥질환의 중증도 역시 증가되는 소견을 보였다. 관상동맥질환이 동반된 죽상동맥경화성 하지동맥폐쇄증 환자에서 관상동맥 우회술 및 관상동맥 중재적 시술을 병합하여 하지동맥 우회술을 시행한 경우, 하지동맥 우회술의 단독시행에 비해 사망률이 현저히 감소하였다. 결론: 과거력상 심질환이 없거나 허혈성 심질환의 주증상이 없는 죽상동맥경화성 하지동맥폐쇄증 환자에서 특히, 고령, 고혈압, AVO score가 높은 환자군에서는 수술 전 관상동맥조영술을 시행하여 동반되는 관상동맥 질환을 파악한 뒤 이에 대한 적극적인 치료를 시행하여야 한다.

Congenital coronary arterial fistulae are the most prevalent hemodynamically significant congenital coronary artery malformations. Definition of congenital coronary arterial fistula is a direct communication between a coronary artery and the lumen of one of the four cardiac chambers or coronary sinus or SVC, pulmonary artery or pulmonary vein close to the heart. It is often associated with additional congenital or acquired heart disease. A 49 year old male patient was admitted with the chief complaints of anginal pain and exertional dyspnea for 9 months. He was diagnosed as the right coronary arterial fistula combined with right coronary arteriosclerotic stenosis and old inferior myocardial infarction by cardiac evaluation. The right coronary arterial fistula was communicated between the just distal portion of acute marginal branch and coronary sinus. The operative procedure was as followings; after suture ligation of fistula opening in the coronary sinus under beating heart, coronary arterial bypass grafting with saphenous vein was performed at the just proximal portion of the posterior descending branch under cardiopulmonary bypass. The postoperative course was uneventful and he was discharged without anginal pain at the 8th postoperative day.

Recently, intracranial atherosclerosis has become a major cause of ischemic stroke, appearing more frequently in Koreans than Caucasians. Symptomatic or asymptomatic intracranial atherosclerosis is a disease that could recur readily even during the treatment with anti-platelet agents. When the symptoms develop, ischemic stroke can not be recovered readily. Therefore, aggressive treatments such as endovascular therapy and bypass surgery are required in addition to medical treatment for the intracranial artery stenosis. Recent intracranial stenting and drug eluting stenting have shown as very advanced effective therapeutic modalities. Nevertheless, until now, a randomized controlled study has not been conducted. Regarding bypass surgery, since the failed EC-IC bypass surgery study performed 20 years ago, extensive studies on its efficacy has not been conducted yet, and thus it has to be performed strictly only in hemodynamically compromised patients. Unless breakthrough drugs that suppress the progression of intracranial atherosclerosis and the formation of thrombi, and facilitate the regression of the arterial stenosis, the treatment concept of the recovery of the blood flow of stenotic arterial territory by mechanical recanalization or bypass surgery would be remained for the prevention as well as treatment of ischemic stroke caused by intracranial atherosclerosis.

The evaluation of the effectivess of ongoing cardiopulmonary resucitation efforts is dependent on the commonly used methods, such as the presence of femoral or carotid artery pulsations, arterial blood gas determinations, peripheral arterial pressure and intracardiac pressure monitoring. But recent studies suggest that end-tidal carbon dioxide tension serves as a non-invasive measurement of pulmonary blood flow and therefore cardiac output under constant ventilation. A prospective clinical study was done to determine whether end-tidal carbon dioxide monitoring in open heart surgery under cardiopulmonary bypass could be used as a prognostic indicator of bypass weaning. We monitored end-tidal PCO2 values continuously during cardiopulmonary bypass in 30 patients. "Ohmeda 5210 CO-2 monitor" under infrared absorption method were incorperated into the ventilator circuit by means of a side point adaptor between endotracheal tube and ventilator tubing. 18 patients[Group I ] were res-ucitated from partial bypass followed by aorta cross clamp off and 12 patients[Group II ] from aorta cross clamp off followed by partial bypass. But there was no difference between two groups[p>0.05]. The value of end-tidal carbon dioxide tension during ventricular fibrillation or nearly arrest state was 6.6$\pm$2.9 mmHg, and at the time of spontaneous beating was 19.3$\pm$5.6 mmHg[Mean$\pm$Standard deviation], In conclusion end-tidal carbon dioxide tension monitoring provides clinically useful, continous, noninvasive and supplementary prognostic indicator during cardiopulmonary bypass weaning procedures.rocedures.
