The occlusive coronary artery disease presents a potential threat to a significant population in the United State. According to many case reports, the increasing incidence of coronary artery disease due to atherosclerosis is noted in Korean, recently. We experienced one case of coronary artery disease. He was a 68 year old male who had been suffered from hypertension since 1 5 years ago, and had intermittent conservative treatment at local clinic. He had been afflicted with severe chest pain on exertion, but this symptom was relieved on rest. Pre-operative EKG finding revealed no any other ischemic sign. Significant S-T segment depression was noted at lead II, aVF, V3, V4, and V5, and inverted T wave in V5 and V6 after Master`s test. Simple chest X-ray finding showed emphysematous field, bilaterally. Final pre-operative diagnosis was made by coronary angiogram, which showed almost 90% degree of occlusive lesion in the proximal part of left main coronary artery above the origin LAD artery. He was treated successfully by aorta-coronary saphenous vein graft under extra-corporeal circulation in May, 1987. He has been followed up with uneventful course.

Recently we experienced coronary artery bypass graft in two patients over 70years of age. Among them, one case was 74 old year male and the other case was 73 old year male. The coronary artery diseases of them were angiographically diagnosed to triple vessel diseases. We only used great saphenous vein as graft vessel in two patients. The postoperative courses were good except mediastinal bleeding in 1 case. They were discharged with good results. They were still healthy 40 months in one and 30 months in the other after coronary artery bypass grafting.

We report a redo coronary artery bypass grafting (CABG) in a 55-year-old man. Angina recurred 7 years after the initial surgery. Coronary angiography showed all patent grafts except a faint visualization of the in situ right gastroepiploic artery (RGEA) graft, which was anastomosed to the posterior descending coronary artery, associated with celiac axis stenosis. Redo-CABG was performed at postoperative 10 years because of aggravated angina and decreased perfusion of the inferior wall in the myocardial single photon emission computed tomography. The saphenous vein graft was interposed between the 2 in situ grafts used previously; the right internal thoracic artery and RGEA grafts. Angina was relieved and myocardial perfusion was improved.

We report a case of 53-year-old woman with an injured popliteal artery due to excessive drilling with a drill bit during medial opening wedge high tibial osteotomy (MOWHTO). Pseudoaneurysm was diagnosed three days after surgery and confirmed by urgent computed tomography (CT) angiography. Open vascular surgery with resection of the perivascular hematoma and end-to-end anastomosis using ipsilateral saphenous vein interposition graft was performed. CT angiography at 8 months postoperatively showed that blood flow was maintained without obstruction of the graft site and active dorsiflexion of the foot was possible. To reduce neurovascular injury during MOWHTO, it is important not to drill the far cortex at the proximal part of the osteotomy site when using a drill bit, and the metal should be positioned posteromedially as much as possible.

A twenty six year old man was admitted to our clinic for bleeding from a venous ulcer of the left leg. His left femoral vein had been ligated for bleeding control after a traffic accident that happened when he was 5 years old. He had a varicose vein, stasis dermatitis, and a venous ulcer on his left leg. To shunt left femoral venous return to the right femoral vein, we did a crossover bypass with arteriovenous fistula using the right greater saphenous vein. To get good patency of the arteriovenous fistula, the bypass graft was closed 6 weeks after the initial operation. He maintained his left leg circumference relatively well for 6 months after the operation. We report the case of a patient who had a vein crossover bypass for a chronic femoral vein ligation.

Sixty-one consecutive patients with coronary artery bypass graft for myocardial revascularization were retrospectively reviewed to analyze various pattern of postoperative complication and death during hospital stay from Nov. 1988 to Oct. 1992. Fortytwo of the patients were male and nineteen female. The mean age was 56 and 51 years in male and female. Preoperative diagnosises were unstable angina in 14 of patients, stable angina in 28, postmyocardial infarction state in 15, and state of failed percutaneous transluminal coronary angioplasty in 4. 141 stenosed coronary arteries were bypassed with use of 20 pedicled internal mammary artery and 124 reversed saphenous vein grafts. Postoperative complications and perioperative death were as follows: 1. Of 61 patients undergoing operation, peri and postoperative over all complication occured in 15 patients [ 25% ]; newly developed myocardial infarction in 4, intractable cardiac arrhythmia including atrial fibrillation and frequent ventricular premature contraction in 3, bleeding from gastrointestinal tract in 2, persistent vegetative state as a sequele of brain hypoxia in 1, wound necrosis in 1, left hemidiaphragmatic palsy in 3 and poor blood flow through graft in 2. 2. Operative mortality was 8%[5 patients]. 3 out of these died in operating room; 1 patient by bleeding from rupture of calcified aortic wall, 1 by air embolism through left atrial vent catheter, 1 by low cardiac output syndrome. 2 patients died during hospital stay; 1 by acute respiratory distress syndrome with multiuple organ failure, 1 by brain death after delayed diagnosis of pericardial tamponade.

During the period from November 1981 through June 1986, 18 cases of coronary arterial bypass graft were performed at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital. They consisted of 13 males and 5 females with the mean age of 49 [range: 28-69 years]. History of myocardial infarction was noted in 50% of the patients and cardiomegaly on chest PA in 2 patients with preserved LV function. On resting EKG, except the evidences of old myocardial infarction, the findings of LVH were noted in 7 cases, acute myocardial infarction in 2, diffuse myocardial ischemia in 1, and significant ventricular arrhythmia in 2 cases. The angina by type of presentation is stable in 3 patients, unstable in 15 patients with resting, postinfarction and progressive angina as the criteria of unstability. The patterns of involvement of significant disease were single vessel involvement [5 cases] double vessel involvement [8 cases], and triple vessel involvement [5 cases] including 5 cases of left main coronary arterial diseases. The pattern of coronary arterial disease in individual patient was one or more stenosis of the proximal left coronary arterial system with or without right coronary involvement, in every case. We performed 9 cases of double bypass and 9 cases of triple bypass with great saphenous vein using single anastomosis technique except in 4 cases, One of the 4 cases is our first case, sequential anastomosis between LAD and diagonal was performed due to shortage of the prepared vein graft. In the other 3 cases, our latest experience, we adopted the left internal mammary artery for the left anterior descending coronary revascularization. The distribution of sites of distal anastomosis revealed more striking predilection to LAD, showing our attention on the significance of the revascularization of LAD system. The ischemic time was 35 minutes per graft and mean number of grafts per patient was 2.5. Of the 18 patients, 13 [77.2%] had complete revascularization, and incomplete in 5 cases with the causes of incompleteness as presented. The early results of operation were as followed: surgical death in 2 [11%], perioperative infarction 2 [11%], need of inotropic support 5 [28%], arrhythmia 2 [11%], wound problem, bleeding, and emotional dysfunction. The actuarial anginal free survival during the period of 6 months through 2 years was 85.2% with excellent symptomatic control according to the angina classification of Canadian Cardiovascular Society.

Background: As the internal mammary artery is far superior to the vein in the patency rate recently there has been a tendency to use the arterial graft as much as possible in coronary artery bypass grafts with the expectation of better the short- and long-term patency rate. Material and Method: We sequentially grafted the diagonal and the left anterior descending artery significantly influencing the cardiac function with the internal mammary artery. There were 32 cases of sequential grafts from July 1993 to December 1998: 21 men and 11 women. The age range was from 43 to 69 years with a mean age of 56.64$\pm$6.41 years. There were 22 unstable angina 7 stable angina and 3 acute myocardial infarction. 8 cases of them were accompanied by stenosis of the left main coronary artery. The grafts for coronary artery bypass surgery included the great saphenous vein at 60 the right gastroepiploci artery at 5 and the left internal mammary artery at 64 coronary arteries. Result: One patient died from sepsis and multiorgan failure. Complications included wound infections in two cases and gastrointestinal bleeding in one patient. All patients showed decrease or disappearance of angina after operation. The postoperative coronary angiogram performed in 9 patients showed neither occlusion nor stenosis of the grafts. Conclusion: This study suggests that sequential anastomosis of the internal mammary artery to the diagonal and the left anterior descending artery may result in excellent short-term patency diagonal and the left anterior descending artery may result in excellent short-term patency rate and be useful for the coronary artery bypass graft using only arterial grafts

Osteochondroma is a hyperplasic bony lesion caused by subperiosteal displacement of physeal cartilages, and the most common benign bone tumor. Osteochondromas rarely cause vascular complications, but when encountered, acute ischemia, phlebitis, and arterial puncture are the most common. They are caused by the mass effect or by the sharp end of the tumor. Deep vein thrombosis may be caused by impaired venous blood flow or a hypercoagulable blood state, but sometimes no predisposing cause can be found. We experienced a patient with deep vein thrombosis caused by the mass effect of an asymptomatic osteochondroma, and treated him successfully by excising the osteochondroma and performing a saphenous vein graft after resecting obstructed vein.

We experienced six cases of pseudoaneurysm of the peripheral artery which occurred after stab wound or after diagnostic and operative procedures. Among 6 cases, 4 cases of pseudoaneurysm were developed in the femoral arteries, and others were the subclavian and the axillary artery. Two of 6 cases were combined with previous arterio enous fistula. Doppler imaging and angiogram were performed for the dignosis and an operation. Operative procedures were resection of the aneurysm, ligation of the involved arteries and reconstruction of the artery with the autogenous saphenous vein or the cephalic vein graft. Each operations were successfully performed without any disability.
