1/95. Simultaneous operation for minimally invasive direct coronary artery bypass and abdominal aortic aneurysm repair.Simultaneous minimally invasive direct coronary artery bypass and abdominal aortic aneurysm repair were conducted in a 66-year-old man uneventful, requiring no transfusion. Surgery required 9 hours and 2 minutes. The tracheal tube was extubated in the operating room. Postoperative bleeding was 215 ml. The postoperative course was very smooth, with the patient able to walk on postoperative day 1. Postoperative coronary arteriogram and aortogram showed favorable results and the patient was discharged on day 23 after surgery.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/95. Severe cutaneous cholesterol emboli syndrome after coronary angiography.cholesterol embolization syndrome is due to dislodgment of cholesterol crystals from the atherosclerotic plaques lining the walls of major arteries resulting in an occlusion of small arteries. We describe a case of severe cutaneous cholesterol emboli syndrome following repeat coronary angiography showing by our observation that this syndrome is often unrecognized or misdiagnosed and that a better evaluation of risks factors in patients undergoing invasive procedures could prevent this severe complication.- - - - - - - - - - ranking = 0.83333333333333keywords = coronary (Clic here for more details about this article) |
3/95. saphenous vein graft ectasia: an unusual late complication of coronary artery bypass surgery. A case report.Aneurysms and ectasias of saphenous vein grafts are infrequent complications of coronary artery bypass surgery. They usually present as an expanding asymptomatic mediastinal mass on chest x-ray film or computed tomography scan. Though rare, they must be excluded from the differential diagnosis of mediastinal masses to avoid potentially dangerous needle biopsy. The authors describe ectasia of a saphenous vein graft in a 62-year-old man 14 years after coronary artery bypass surgery. The relevant literature is also discussed.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
4/95. rectum and sigmoid colon necrosis due to cholesterol embolization after implantation of an aortic stent-graft.Endovascular treatment of abdominal aortic aneurysms (AAAs) with stent-grafts is increasingly performed. Recent studies have shown that stent-graft placement for AAA is technically feasible and can effectively exclude aneurysms from the circulation. However, complications related to the procedure, such as graft thrombosis, migration of the prosthesis, peripheral embolization, and leaks with incomplete exclusion of the aneurysmal sac, have been reported. We report a case of rectum and sigmoid colon necrosis with fatal outcome due to cholesterol embolization after implantation of a stent-graft for an infrarenal AAA.- - - - - - - - - - ranking = 0.041362079024048keywords = circulation (Clic here for more details about this article) |
5/95. coronary artery bypass grafting in a case with severe aortic atheromatosis associated with abdominal aortic aneurysm.A 69-year-old man with coronary artery disease associated with abdominal aortic aneurysm underwent a one-stage operation utilizing a low-flow cardiopulmonary bypass. Ordinary cardiopulmonary bypass was abandoned as a result of severe atheromatous finding in the entire aorta. However, coronary artery bypass grafting without cardiopulmonary bypass was hazardous as a result of heart enlargement and deteriorating function. Therefore, the abdominal aortic aneurysm was first replaced with a bifurcated graft. coronary artery bypass grafting with two arterial grafts was then performed successfully on the beating heart with the support of a low-flow cardiopulmonary bypass connected to the bifurcated graft.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
6/95. Endovascular stent-grafting via the aortic arch for distal arch aneurysm: An alternative of endovascular stent-grafting in a complicated case.A 67-year-old man with severe discomfort was diagnosed with a rupture of the thoraco-abdominal aneurysm, a distal arch aneurysm and triple coronary artery disease. After emergency surgery for a thoracoabdominal aneurysm, a scheduled surgery for coronary artery bypass grafting and endoluminal stent-grafting for the distal arch aneurysm was performed simultaneously. A stent-graft was introduced into the descending aorta via a small incision on the arch aorta. Open endovascular stent-grafting via the arch aorta is an alternative for repairing a distal arch aneurysm with coronary artery bypass grafting.- - - - - - - - - - ranking = 0.5keywords = coronary (Clic here for more details about this article) |
7/95. Minimally invasive direct coronary artery bypass combined with abdominal aortic aneurysm repair.BACKGROUND: For simultaneously combined coronary artery bypass surgery with infrarenal abdominal aortic aneurysm (AAA) repair, a relatively high operative mortality and morbidity have been reported. methods: From February 1998 to December 1998, simultaneous minimally invasive direct coronary artery bypass combined with the AAA repair was performed for 4 patients (3 males, 1 female; mean age, 74 /-7 years). Three were high-risk patients: 2 were over 75 years of age, 2 had respiratory insufficiency, and 1 had severe renal impairment. RESULTS: There were no mortalities. The endotracheal tube was removed within approximately 12 hours, and the postoperative courses were uneventful. During 4 /-4 months of follow-up, there was neither angina recurrence nor other morbidity. CONCLUSIONS: Minimally invasive direct coronary artery bypass combined with AAA repair was safe even for high-risk patients.- - - - - - - - - - ranking = 1.1666666666667keywords = coronary (Clic here for more details about this article) |
8/95. Successful completion of endoluminal repair of an abdominal aortic aneurysm after intraoperative iatrogenic rupture of the aneurysm.PURPOSE: A method of achieving successful completion of endoluminal repair of an abdominal aortic aneurysm (AAA) in the presence of intraoperative iatrogenic rupture of the aneurysm is reported. methods: An 83-year-old woman with an AAA that was 7 cm in diameter was treated electively by means of endoluminal repair with a Vanguard bifurcated prosthesis (boston Scientific, Natick, Mass). No difficulty was experienced with the introduction of the delivery catheter, despite extreme angulation in the aneurysm. An acute episode of hypotension prompted an aortogram to be performed. Extravasation of contrast outside the aneurysm sac was demonstrated. The balloon on the delivery catheter was immediately advanced to the suprarenal aorta and inflated. hypotension was reversed, and hemodynamic stability was restored, thus enabling deployment of the prosthesis to proceed and the repair to be completed by means of the endoluminal method. RESULTS: The patient's blood pressure remained stable after deflation of the balloon, allowing a postprocedure aortogram to be performed. Exclusion of the aneurysm sac was demonstrated. Exclusion of the aneurysm sac from the circulation and a large retroperitoneal hematoma were confirmed by means of a postoperative contrast computed tomography scan. convalescence was complicated by acute renal failure, pneumonia, and prolonged ileus. The patient remained well and active at the follow-up examination 6 months after operation. CONCLUSION: Iatrogenic perforation of an AAA during endoluminal repair may be treated by endovascular means and does not necessarily require conversion to open repair, although this may be the safest option.- - - - - - - - - - ranking = 0.041362079024048keywords = circulation (Clic here for more details about this article) |
9/95. Unusual complications in an inflammatory abdominal aortic aneurysm.An unusual case of an inflammatory abdominal aortic aneurysm (IAAA) associated with coronary aneurysms and pathological fracture of the adjacent lumbar vertebrae. The associated coronary lesions in cases of IAAA are usually occlusions. In the present case, it was concluded that a possible cause of the coronary aneurysm was coronary arteritis and the etiology of the pathological fracture of the lumbar vertebrae was occlusion of the lumbar penetrating arteries due to vasculitis resulting in aseptic necrosis. Inflammatory AAA can be associated with aneurysms in addition to occlusive disease in systemic arteries. The preoperative evaluation of systemic arterial lesions and the function of systemic organs is essential.- - - - - - - - - - ranking = 0.66666666666667keywords = coronary (Clic here for more details about this article) |
10/95. Report of a patient with aortic dissection evolving into binocular ischemic retinopathy.BACKGROUND: Carotid artery disease is known to cause a variety of ischemic ocular syndromes. We report a patient with an aortic dissection that evolved into binocular ischemic retinopathy. methods: Case report. RESULTS: A 49-year-old male patient presented with stomach pains and with no ophthalmologic symptoms. After extensive examination, a diagnosis of aortic dissection was made to account for the acute abdominal pain. Sixteen days later, he noted binocular photopsia and ophthalmoscopy revealed ischemic retinopathy. Arterial stent implantation and right coronary reconstitution surgery were performed. Subsequently, the ischemic lesions in the retina disappeared and no abnormality was observed by retinal angiography 1 year later. CONCLUSION: Binocular ischemic retinopathy can be a sign of aortic or carotid dissection, and these observations suggest that aortic dissection should be included in the differential diagnosis whenever ischemic changes are detected in the retina.- - - - - - - - - - ranking = 0.16666666666667keywords = coronary (Clic here for more details about this article) |
