A case of Marfan’s syndrome with atresia of right coronary artery is reported. A 45-year-old woman, who was diagnosed as Marfan’s syndrome 1 year ago, came to the hospital complaining of acute chest pain. The patient showed arachynodactyly, pectus carinatum, and long and slender extremities. In echocardiography there were severe aortic regurgitation measured grade IV and aortic dilatation of ascending aorta maximally 5.9 cm in diameter. Mitral regurgitation was mild, but there were also moderate left ventricular dilation and moderately decreased ejection fraction of left ventricle. At operation, atresia of right coronary artery was found. We performed Bentall type operation with SJM 27mm valved conduit for left coronary artery, and Piehler’s modification for right coronary artery bypass using 6mm PTFE graft. The atretic portion of right coronary artery from the suspected right coronary ostium to distal coronary flow was about 4 cm in length. The combination of right coronary artery atresia and Marfan’s syndrome is very rare. The author describes the rare case, which is treated with combined technique of Bentall and Piehler modification for reconstruction of coronary circulation.

Background: Distal anastomosis using artificial vascular graft is difficult when luminal size mismatch occurred owing to severe occlusion of popliteal artery and its branches. So we reconstructed blood flow to ischemic lower limb by using autologous greater saphenous vein in situ graft (GSVISG) as vascular graft material. Material and Method: From July 2000 to July 2005, 26 patients treated using GSVISG. We analyzed clinical results retrospectively by chart review. Result: There was no in hospital or early postoperative death and 6 late deaths occurred during follow up period. Postoperative complications were 5 cases of early graft obstruction, 2 cases of wound dehiscence, 1 case of graft aneurysmal change, 1 case of seroma formation at inguinal wound and 1 case of graft injury during valvulotomy. Overall patency rate during follow up period was 69.3%. Conclusion: Greater saphenous vein in situ graft is acceptable vascular graft for arterial occlusive disease of lower extremity.

Peripheral arterial occlusive disease (PAOD) of the femoropopliteal artery is commonly caused by atherosclerosis. It can present with varying clinical symptoms depending on the degree of disease, ranging from intermittent claudication to critical limb ischemia and tissue loss. Therefore, appropriate and timely treatment is required to improve symptoms and salvage the affected limbs. Interventional approaches for femoropopliteal arterial disease commonly include percutaneous transluminal angioplasty, atherectomy, and stent placement. Over the years, endovascular recanalization has been widely performed for treating PAOD due to continuous developments in its techniques and availability of dedicated devices with the inherent advantage of being minimal invasive. In this review, we introduce various types of endovascular treatment methods, discuss the results of clinical research from existing literature, and illustrate the treatment procedures using representative images.

Obstructive intracardiac lesions, like mitral stenosis or insufficiency (MR), by myxomas of the left atrium have been commonly reported, but the attenuation of MR by myxoma combined with coronary artery disease is very rare. We report a 70-year-old female patient whose left atrial myxoma had attenuated moderate MR to mild MR and required mitral valve surgery after removal of the myxoma. She also had coronary artery disease, severe pulmonary hypertension and moderate tricuspid regurgitation due to the mitral valve lesions obstructed by myxoma. The patient underwent removal of myxoma, mitral and tricuspid valve reconstructions, and coronary artery bypass grafting. She was discharged at the postoperative 14 day without any problems.

Bow hunter's syndrome is a rare disease that shows the symptoms of vertebrobasilar insufficiency resulting from a dynamic obstruction or stenosis of the vertebral arteries during neck movement. This paper reports a case of a 59-year-old male who visited the emergency room with diplopia, tinnitus, and gait disturbance. Magnetic resonance imaging and angiography revealed a multiple cerebellar infarct, total obstruction of the right vertebral artery, and dynamic obstruction of the left vertebral artery during neck extension. As the infarction worsened, a thrombectomy was done. Posterior decompression and fusion at C5-6 were performed for the left vertebral artery. The left vertebral arterial patency was confirmed by intraoperative and postoperative angiography. No recurrence of the symptoms was observed for six months after surgery. Physicians need to pay attention to the diagnosis of vertebrobasilar insufficiency caused by an obstruction of the vertebral arteries during neck extension in cervical instability patients.

To compare between calcium scoring CT (CSCT) and Low-dose CT (LDCT) image finding for coronary artery calcification (CAC) in screening of lung disease by MDCT. A total of 61 subjects who retired-workers exposed to inorganic dust were performed LDCT and CSCT by using a MDCT scanner on the same day, after be approved by the institutional review board, and obtaining the written informed consent from all subjects. LDCT images were read for detecting lung diseases as well as CAC by a experienced chest radiologist, then the subjects were divided either the positive group with CAC or the negative group without it. The CSCT was used to quantify and detect the presence of calcification in the coronary artery, and score of CAC calculated by using a Rapidia software (ver 2.8). In all coronary arteries, calcium score of positive group was higher better than that in negative group, especially in the total calcium (13.7 vs. 582.9, p=0.008) and the left anterior descending artery (3.2 vs. 249.0, p=0.006). CAC findings between CSCT and LDCT image were showed excellent agreement in cut-off point 100(K-value=0.80, 95% CI=0.69-0.91) from total calcium score. CAC findings on LDCT images showed the higher relation with CSCT. Therefore, the obstructive coronary artery disease could be predicted by CAC on LDCT images for screening of lung diseases.

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.

Occlusion of a coronary artery ostium and especially occlusion of the right by an aortic cusp is a rare condition. We experienced an adult patient with occlusion of the right coronary ostium that was due to fusion of the right coronary cusp to the aortic wall along with underlying rheumatic aortic valve stenosis. During the operation, the adherent right coronary cusp was excised. After confirming that the right coronary ostium was patent, the other cusps were removed, and this followed by replacement of the aortic valve with a mechanical valve. The postoperative course was uneventful.
