Aggressive revascularization of the ischemic lower extremities in atherosclerotic occlusive diseases or acute embolic arterial occusion due to cardiac valvular disease by thromboembolectomy or an arterial by- pass operation has been advocated by some authors. To evaluate clinical pattern and operative outcome of the ischemic lower extremity, surgical experience in 101 patients who were admitted to Dong-A Univer- sity Hospital between March 1990 and August 1995 was analyzed. The patients were 92 males and 9 females ranging fro 25 to 87 years of age. The underlying causes of arterial occlusive disease were atherosclerotic obliterances in 54 case, Buerger's disease in 20 cases, thromboembolism in 24 cases, vascular trauma in 3 cases and pseudoaneurysm in 3 cases. - The major arterial occlusive sites of atherosclerotic obliterance were femoral artery in 30 cases, iliac artery in 23 cases, popliteal artery in 10 cases, distal aorta in 6 cases and the major arterial occlusive sites of Buerger's disease were posterior tibial artery in 14 cases, anterior tibial artery in 8 cases, popliteal artery in 5 cases. The operative procedures of arterial occlusive disease were bypass graft operation in 61 cases, thromboembolectomy in 21 cases, sympathectomy in 20 cases. Arterial bypass operations with autogenous or artificial vascular prosthesis were done in 61 cases which Included femoro-popliteal bypass in 21 cases, femoro-femoral bypass in 15 cases, axillo-bifemoral bypass in 7 cases, aorto-bifemoral with inverted Y-gr ft In 3 cases, femoro-profundafemoral bypass in 3 cases, popliteo-tibial bypass in 2 cases, aorto-iliad bypass in 1 case Over all postoperative patency rates were 83.6 oyo at 1 year, 75.5% at 3 years and limb salvage rate was 86.8 oyo . Six patients died in the hospital following vascular surgery for ischemic lower extremities, although the causes of death were not directly related to the vascular reconstructive operative proccedures. The leading causes of death were in the order of multiple organ failure, acute renal failure, and sepsis.

From Dec. 1992 to Dec. 1995, 20 patients with atherosclerotic occlusive disease in the lower extremities underwent arter al bypass surgery. The age of the patients ranged between 46 and 77 years(mean .60.8 years) and the most prevalent incidence was in the 7th decades. The mean follow up period was 18.8 months ranging from 4 to 36 months. Associated diseases were diabetus mellitus(25%), hypertension (35%), cerebrovascular accident(25%), and acute myocardial infarction(5%). Disabling intermittent claudifcation(35%), resting pain(20%) or ischemic gangrene(or ulceration)(45%) were operative indications. Aorto-bifemoral bypass in 4 cases, aorto-single femoral bypass in 2 cases, Aorto-bifemoral bypass and femoropopliteal bypass in 3 cases, aorto-single femoral bypass and femoropopliteal bypass in 1 case, femoropopliteal bypass in 4 cases, femorotibial bypass in 1 case, popliteotibial bypass 4 cases and femorofemoral bypass in 1 case were the surgical approches. Early thrombosis(2 cases) and wound infection(2 case) were main complication. Postoperative complication rate was 20% . Postoperative patency rates re 92.6% at 6 months, 84.2% at 1 year, 75.4% at 2 years and 69.4% at 3 years.

Aggressive revascularization of the ischemic lower extremities in atherosclerotic, occlusive diseases or acute embolic arterial occlusion due to cardiac valvular disease by thromboembolectomy or an arterial bypass operation has been advocated by some authors. We have performed 68 first time vascular operations, including thromboembolectomies on RR patients with ischemic lower extremities, within an 11-year-and-6-month period, from January 1974 to June 1984. We have reviewed and analyzed our vascular operative procedures and post operative results. The patients upon whom thromboembolectomies were performed were 42 males and 13 females ranging from 5 to 72 years of age. The major arterial occlusive sites were common iliac artery in 20 cases, femoral artery in 21 cases, popliteal artery in 8 cases, common iliac artery and femoral artery in 4 cases, and femoral artery and popliteal artery in 3 cases. The underlying causes of arterial occlusive disease were atherosclerosis obliterans in 34 cases; Buerger`s disease in 3 cases; emboli due to cardiac valvular disease in 13 cases; and vascular trauma in 4 cases, including cardiac catheterization in I of those cases. Arterial bypass operations with autogenous or artificial vascular prosthesis were done in 31 cases. Amputations were done on 2 patients carrying out any more vascular operative procedures would have been of no benefit to them. Our bypass operations for ischemic lower extremities were classified as follows: those done between the abdominal aorta and the femoral artery in 17 cases, including those done between the aorta and the bifemoral arteries with a Y graft in four of those cases and long ones done from the axillary to the femoral artery in 4 cases. Five patients died in the hospital following vascular surgery for ischemic lower extremities, the causes of death were not directly related to the vascular reconstructive operative procedures. The leading causes of death were respiratory failure due to metastatic lung carcinoma: renal failure due to complications from atherosclerosis obliterans; sepsis from open, contaminated fractures of the tibia and fibula; and myocardial failures due to open heart surgery in one case and reconstructive surgery of the ascending aorta in another.

To investigate the presence of infectious agents in human atherosclerotic arterial tissues. Atherosclerotic plaques were removed from 128 patients undergoing carotid endarterectomy or other bypass proce­dures for occlusive disease, and from twenty normal arterial wall samples, obtained from transplant donors with no history of diabetes, hypertension, smoking, or hyperlipidemia. Using the polymerase chain reaction (PCR) or reverse transcription-PCR, these samples were analyzed for the presence of Chlamydia pneumoniae, cytomegalovirus, enterovirus, adenovirus, herpes simplex viruses types 1 and 2, and Epstein-Barr virus. The amplicons were then sequenced, and phylogenetic analyses were per­formed. Enteroviral RNA was found in 22 of 128 atherosclerotic vascular lesions $(17.2\%),$ and C. pneu­moniae and cytomegalovirus were each found in 2 samples $(1.6\%).$ In contrast, adenovirus, herpes simplex viruses, and Epstein-Barr virus were not identified in any of the atherosclerotic samples. Enterovirus was detected in 6/24 $(25.0\%)$ aortas, 7/33 $(21.2\%)$ carotid arteries, 6/40 $(15.0\%)$ femoral arteries, and 3/31 $(9.7\%)$ radial arteries of patients with chronic renal failure. There were no infectious agents detected in any of the control specimens. Using phylogenetic analysis, the enterovirus isolates were clustered into 3 groups, arranged as echovirus 9 and coxsackieviruses Bl and B3. Enteroviral RNA was detected in $17.2\%$ of atherosclerotic plaques, but was not observed in any of the control spec­imens. This suggests a connection between enteroviral infection and atherosclerosis. These findings dif­fer from those of other studies, which found more frequent incidence of C. pneumoniae and cytomegalovirus infection in atherosclerotic plaques.

Occlusive coronary artery disease presents a potential threat to a significant population in the United States. According to many case reports, the increasing incidence of coronary artery disease due to atherosclerosis is noted in Korean, recently. Operative vascular procedures have increased steadily in number over the past 20 years in the United States. There have been many isolated case reports about coronary artery surgery, but these had little clinical impact. Nowadays, major three coronary bypass surgery has developed principally at three cardiac centers in the United States since 1967. Among three coronary bypass operation, the aorta-coronary artery saphenous vein bypass graft was first demonstrated by Favolaro and Effler at the Cleveland Clinic in 1967. We experienced one case of coronary artery disease, which was treated successfully by aorta-coronary saphenous vein graft with mild hypothermia under extracorporeal circulation in May, 1977. Saphenous vein was removed from above the knee and was 2.5 mm in diameter. The left ventricle was not vented for the left ventricle was not overdistended. Temporary artificial pace-maker-Medtronic-was implanted for the prevention and treatment of post-operative arrhythmia and heart block in post-operative first day. He is a 57 year old male businessman who had been suffered from hypertension [200 mmHg in systolic pressure] since 4 years ago, who had intermittent conservative treatment at local clinic. He had been afflicted with severe chest pain with choking sensation for 50 days. This symptom was aggravated exposing cold weather, or cold water, but was respond to rest. Pre-operative ECG revealed no any other ischemic sign except sinus bradycardia. Significant S-T segment depression was noted at lead II, AVF after double 5 minutes exercise, indicating positive Master`s test. Serum cholesterol was slight elevated to 253 mg/dl. Final pre-operative diagnosis was made by coronary arteriogram, which showed about 1.0-cm segmental 90 % occlusive atherosclerotic lesion in the proximal part of right coronary artery above the origin of acute marginal artery. Left coronary artery revealed good patency and there was no collateral circulation between right and left coronary artery .Hospital course was not eventful. He was discharged with good result on the post-operative day. He has been free from chest pain for longer than 2 years. And also the arterial flow in the coronary bypass graft is auscultated with the pocket-sized ultrasonic velocity detector, which shows the patency of the coronary bypass graft good.

Moyamoya disease (MMD) is a progressive occlusive disease of the cerebral vasculature with particular involvement of the circle of Willis and the arteries that feed it. MMD is one of cerebrovacular accident,which is treated with sugical maeuver in pediatic neurosurgery. Moyamoya (ie, Japanese for "puff of smoke") characterizes the appearance on angiography of abnormal vascular collateral networks that develop adjacent to the stenotic vessels. The steno-occlusive areas are usually bilateral, but unilateral involvement does not exclude the diagnosis. The exact etiology of moyamoya disease is unknown. Some genetic predisposition is apparent because it is familial 10% of the time. The disease may be hereditary and multifactorial. It may occur by itself in a previously healthy individual. However, many disease states have been reported in association with moyamoya disease, including the following: 1) Immunological - Graves disease/thyrotoxicosis 2) Infections - Leptospirosis and tuberculosis 3) Hematologic disorders - Aplastic anemia, Fanconi anemia, sickle cell anemia, and lupus 4) Congenital syndromes - Apert syndrome, Down syndrome, Marfan syndrome, tuberous sclerosis, Turner syndrome, von Recklinghausen disease, and Hirschsprung disease 5) Vascular diseases - Atherosclerotic disease, coarctation of the aorta and fibromuscular dysplasia, 6)cranial trauma, radiation injury, parasellar tumors, and hypertension etc. These associations may not necessarily be causative but do warrant consideration due to impact on treatment.(Mainly neurosurgical operation.) The incidence of moyamoya disease is highest in Japan. The prevalence of MMD is 1 person per 100,000 population. The prevalence and incidence of moyamoya disease in Japan has been reported to be 3.16 cases and 0.35 case per 100,000 people, respectively. With regard to sex, the female-to-male ratio is 1.4:1. A bimodal peak of incidence is noted, with symptoms occurring either in the first decade(5-10yr) or in the third and fourth decades (30-40yr)of life. Mortality rates of moyamoya disease are approximately 10% in adults and 4.3% in children. Death is usually from hemorrhage. In aspect of life insurance, MR is 1700%, EDR is 16 per 1000 persons. Children and adults with moyamoya disease (MMD) may have different clinical presentations. The symptoms and clinical course vary widely from asymptomatic to transient events to severe neurologic deficits. Adults experience hemorrhage more commonly; cerebral ischemic events are more common in children. Children may have hemiparesis, monoparesis, sensory impairment, involuntary movements, headaches, dizziness, or seizures. Mental retardation or persistent neurologic deficits may be present. Adults may have symptoms and signs similar to those in children, but intraventricular, subarachnoid, or intracerebral hemorrhage of sudden onset is more common in adults. Recently increasing diagnosis of MMD with MRI, followed by surgical operation is noted. MMD needs to be considered as the "CI" state now in life insurance fields.

Acute limb ischemia (ALI) due to an embolism is associated with high mortality rate and poor prognosis, and early diagnosis with prompt revascularization is required to reduce the risk of limb amputation or even death. The etiologies of ALI are diverse, and it includes an embolism from the heart and thrombotic occlusion of the atherosclerotic native vessels, stents, or grafts. An uncommon cause of ALI is acute arterial thromboembolism, and atrial fibrillation (AF) is the single most important risk factors for systemic thromboembolism. It is important to correctly identify the source of ALI for secondary prevention, as it depends on the underlying cause. Percutaneous transluminal angioplasty (PTA) has been proven to be a safe and effective treatment for focal atherosclerotic and thrombotic occlusive diseases of the aorta and its major extremity branches. Herein, we report on a 77-year-old female patient with acute upper limb ischemia, treated by PTA using a catheter-guided thrombectomy. He was newly diagnosed with paroxysmal AF (PAF) while evaluation the cause of his acute arterial thromboembolism. We recommend that cardiologists always consider PAF as a possible diagnosis even in patients without any history of AF under ALI because it is possible to develop thromboembolism in clinical practice.

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 %.

Trauma of the vascular structure is not poplular event. In obstructive atherosclerotic vascular disease, we sometimes have needed bypass surgery. The long length subcutaneous prosthetic vascular graft are vulnerable to injury. But prosthetic vessel rupture after trauma has been rare report. A 68-year-old man was referred to Department of Emergency of the Gyeongsang National University Hospital. After he had had a blunt trauma, he found a newly appearing pulsating mass of 10 cm diameter on his right chest wall. The lesion had a turbulent blood flow in the cavity of the mass by ultrasonographic finding. The lesion was a rupture of superficial prosthetic vascular graft under the skin.

Background: The goal of this study was to compare the patency and complications of femoropopliteal bypass with superficial femoral artery stenting for patients with atherosclerotic superficial femoral artery occlusive disease. Material and Method: Between July 2005 and July 2008, we reviewed 29 femoropopliteal bypass procedures (24 patients) with prosthetic grafts (the bypass group) and 19 superficial femoral artery stentings (15 patients) with nitinol stent (the stent group). There were 35 male patients (89.7%) and the mean age of the patients was 69.2 years (range: 48~84). The number of patients who had DM, hypertension and a smoking history was 25 patients (64.1%), 17 patients (43.6%) and 30 patients (76.9%), respectively. 23 (59.0%) patients had skin ulceration or tissue gangrene at admission. Result: There were 27 cases (93.0%) of TASC C&D lesion in the bypass group and 16 cases (84.2%) of TASC A&B lesion in the stent group. There were significant differences for the indications for a procedure between the two groups (p<0.01). The primary patency rates at 6 months, 12 months and 24 months were 91.9%, 79.7% and 79.7% for the bypass group and 93.3%, 86.2% and 86.2% for the stent group, respectively. There were no statistical difference between the two groups (p=0.48). Conclusion: There were no significant differences in the outcome between two groups. TASC C&D lesion and failed intervention therapy should be treated with femoropopliteal bypass surgery, and TASC A&B lesion and the high-risk patients should be treated with femoral artery stent insertion.
