Backgrounds/Aims: Patients who undergo pancreatic surgery with venous resection have high rates of morbidity/mortality. Also, they are high-risk for postoperative venous thromboembolism. Whether this group should be routinely anticoagulated is unknown. This study aimed to establish current anticoagulation practices. Methods: A survey (https://form.jotform.com/220242489107048) was sent out to pancreatic surgeons. Questions covered center volume, venous resection/reconstruction techniques and anticoagulation policies. Results: Sixty-five centers from 17 countries responded. Following a "side-bite" venous resection with a patch repair, 40% used an autologous vein patch, 27% used peritoneum, and 27% used a bovine patch. After formally resecting a segment of vein, 17% of centers used an interposition graft (IG). Left renal vein (41%) and polytetrafluoroethylene (73%) grafts were the most commonly used autologous and prosthetic IGs, respectively. Following a prosthetic IG, an autologous IG, and a "side-bite" resection, 59%, 28%, and 19% of centers provided therapeutic anticoagulation, respectively (66% used low molecular-weight heparin). The duration of therapy provided varied from inpatient stay only (14%) to six months (32%). Conclusions: Our global survey indicates that anticoagulation practices are highly variable. Centers do not agree on when to anticoagulate, how to anticoagulate, or the duration of therapy. A robust trial is required to provide clarity.

A 38-year-old male was admitted to our hospital due to painful swelling of his right popliteal fossa. He had been kicked in his right popliteal fossa during a soccer game about three weeks earlier. Computerized tomographic angiography of the lower extremity demonstrated a 4-cm-wide, 3-cm-long aneurysmal change of the popliteal artery. He underwent aneurysmectomy and graft interposition using a great saphenous vein graft. Pathologic findings of the resected specimen were consistent with those of a pseudoaneurysm.

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.

A 21 year-old male patient had a diagnosis of Budd-Chiari syndrome caused by inferior vena caval obstruction. Conservative medical therapy failed to control the symptoms of both portal hypertension and inferior vena caval stasis. Portocaval or mesocaval shunts may relive the symptoms of chronic forms of Budd-Chiari syndrome. But when inferior vena caval stenosis is severe, another procedure has to be used. Cavoatrial or portoatrial shunt has been suggested. Therefore, a long Dacron graft was placed from the inferior vena cava just below the left renal vein to the right atrium. He exhibited almost complete relief of symptoms for 1.5 year postoperatively. And there was angiographic proof of patency of the graft. This simple procedure should be encouraged in treatment of these patients.

This is a case report of traumatic arterial injuries with false aneurysm & arterio-venous fistula treated surgically at National Medical Center. 3 cases were A-V fistula and 2 cases only false aneurysm. Physiological disturbance were produced by only arteriovenous fistula; In one case ulceration of mid. 1/3 tibia due to diminished arterial flow and in 2 cases left ventricular hypertrophy, in which cases Bramhan`s sign were positive. Removing out the fistulous lesions and aneurysm, all of the arterial continuities has been reconstructed by means of end to end anastomosis, Dacron graft and vein graft, veins were managed by ligations of both ends in two cases and end to end anostomosis in one case. Immediate post operative results were good, and two cases were followed for 10 months.

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.

Avascular necrosis is a significant late complication of talar neck fracture. However, treatment for early stage avascular necrosis has been not established. Two patients with post-traumatic avascular necrosis of talus treated with vascular pedicle graft using lateral tarsal artery were reviewed to determine the efficacy of procedure. The procedure involved grafting the lateral tarsal artery and vein into a hole made in the talus through a anterolateral approach. Follow-up was 12 and 24 months respectively. Two patients had significant pain relief, improved function, no worsening of their radiologic staging. The results are promising enough to recommend consideration of this procedure in early stages of avascular necrosis.

In the mid 1980's, the ITA(internal thoracic artery) graft was clearly recognized to be superior to the sapheonous vein graft in respect to long term patency. Therefore, there has been growing interest in the arterial conduit with the possibility of improving the long term result. We have been performing CABG with GEA since 1998 with the same purpose. For mid-term and long-term follow up, we have been performing postoperative coronary angiography. In this paper, a case of GEA spasm, a purported drawback of this conduit, during postoperative coronary anigiography and relieved by direct infusion of 200$\mu\textrm{g}$ isoket into the GEA is reported. The current case which exemplifies the spastic nature of RGEA is accompanied with coronary angiography.
