Atherosclerosis has more than 60% of the causes of arterial occlusive diseases. The abdominal aorta and lower extremity arteries are the most common sites of occlusion. We have treated surgically 2 cases who had intermittent claudication and were diagnosed as simultaneous aortobifemoral and bilateral femoropopliteal obstruction by angiography, but had ineffective results from medical treatment or angioplasty. Simultaneously aortobifemoral bypass using Hemashield Y graft and bilateral femoropopliteal bypass using autologous greater saphenous vein were done. After operations, the symptom disappeared and there were no specific post-operative complications except abdominal wound dehiscence. In postoperative angiography, we had obtained good patency of bypass graft. We are following up patients through the out patient department without recurrence up to 16 months.

Atherosclerotic giant aneurysm of the common femoral artery is rare. Because the patients who lose timing of the operation face amputation or death, the surgical treatment must be performed at the proper time. A 72-old man was admitted to the hospital because of a 20-days history of pulsatile growing mass on his left groin. After the diagnosis of giant aneurysm of the common femoral artery by computerized tomography and digital subtraction angiography, an emergent operation was performed. Both deep and superficial femoral arteries were successfully reconstructed with Gore-tex grafts after aneurysmectomy. The pathology of the aneurysm was proved to be atherosclerosis.

Purpose : One of the major complication of arterial catheterization is the thrombosis of the iliac or femoral arteries. Tissue loss following femoral artery catheterization is rare. However longterm sequelae such as impaired limb growth and future impairment of vascular access, are also important in pediatric cardiac patients. But standard methods to treat thrombotic complication of arterial catheterization in infants and children is not established. The present study was performed to assess the efficacy of intraarterial catheter-directed urokinase infusion in infants and children with limb ischemia due to arterial thrombosis after cardiac catheterization. Methods : From January 1994 to August 2002, 12 patients with thrombotic femoral artery occlusion after arterial catheterization were treated with catheter-directed urokinase infusion in Dong-A University Hospital. Retrospective analysis of the medical records and angiograms was conducted. Results : The incidence of femoral artery thrombosis after retrograde arterial catheterization, which had not responded to systemic infusion of heparin and/or urokinase, was 2.8 percent. The doses of urokinase were 1,000-4,400 unit/kg/hr and duration of infusion was $50.6{\pm}29.2$ hours(18-110 hours). Clot resolution was complete in all patients who started to receive the intraarterial urokinase infusion within four days after catheterization. Only partial thrombolysis was seen in two patients who were treated with intraarterial urokinase on the 12th and 19th days after thrombus formation. Balloon angioplasty was done for these two patients with partial success. Bleeding complications were seen in two cases. Conclusion : Early use of catheter-directed intraarterial infusion of urokinase is safe and effective in thrombolysis of femoral artery occlusion after cardiac catheterization in infants and children.

Background: This study was performed to investigate the outcomes of vascular operations that were done in patients with atheroscerosis obliterans (ASO) of lower limb. Material and Method: Forty patients underwent vascular operations from December 1996 to June 2004. The patient's records were analyzed retrospectively. Mean age was $66{\pm}8$ years (range, $47{\sim}81$ years). Gender ratio was 37:3 (male:female). Result: The operations were done on 50 lower limbs of 40 patients. The names of operations were femoropopliteal bypass in 12 patients (30%), femorofemoral bypass in 12 (30%), femorofemoral bypass and femoropopliteal bypass in five (12.5%), aorta-lower limb artery bypass in five (12.5%), axillofemoral bypass in two (5%), iliopopliteal bypass in two (5%), and endarterectomy in two (5%). All bypass surgeries were done with prosthetic conduits. Mean follow up period was $33.2{\pm}23.2$ months (range, $3.8{\sim}90.2$ months). The cumulative patency rates of 1 and 5 years were 75.5 and 58.7% respectively. In six patients, amputation of the lower limb was done. In eight patients, 12 complications occurred. After the first operation, 10 patients underwent reoperations. Conclusion: Our lower limb arterial bypass surgery revealed acceptable patency rate, but not a few patients required reoperations. An epochal treatment modality that can inhibit the progress of ASO and improve long term patency should be established.

Extra-anatomic graft bypass is frequently performed instead of standard infrarenal aorto-iliac reconstruction in patients with Leriche syndrome in whom the thrombus extends to the level of the renal arteries. However, many different surgical options are still being attempted due to the unsatisfying long-term graft patency. We performed a descending thoracic aorto-bifemoral bypass graft with 14 and 14-7-7 mm artificial vessels through a posterolateral thoracotomy, a median laparotomy, and a longitudinal inguinal incision in a 48-year-old male who suffered from claudication with Leriche syndrome. After surgery, the patient recovered well and was discharged. The patient walked well without any symptoms during the 6 month follow-up period in the outpatient department. We have concluded that descending thoracic aorto-bifemoral bypass grafting could be considered as an alternative method for patients with Leriche syndrome in whom standard infrarenal aorto-iliac reconstruction is unsuitable.

Cardiac tamponade Is an acute, life-threatening emergency, requiring immediate decompression by a safe and simple method. The most effective method of drainage has been controversial. We experienced successful outcome for the treatment of cardiac tamponade with drainage using the Seldinger technique. The causes of the cardiac tamponade were hemopericardium after mitral and aortic valve replacement and malignant pericardial effusion due to primary lung cancer. They were treated with emergency rainage by the Seldinger technique without procedure-related complications. We believe that this technique is simple, safe for the treatment of cardiac tamponade.

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.

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.

During dissection of the saphenofemoral junction, anatomical variations in the tributaries of the long saphenous vein and external pudendal artery are frequently encountered, but the transpositions of the femoral artery and vein have very rarely been reported. On operation of the varicose vein, the surgical complications can be minimized when the possible deviations in the normal anatomy are taken into the consideration.
