1/554. Bilateral subclavian steal syndrome through different paths and from different sites--a case report.Cases of cerebro-subclavian steal syndrome have been reported in the medical literature since 1960. This most often occurs on the left side because of the higher rate of involvement of the left subclavian artery in comparison to the other brachiocephalic branches of the aortic arch. With the use of the internal mammory artery as a conduit for coronary artery bypass, in the past three decades increasing numbers of coronary-subclavian steal in addition to the cerebro-subclavian steal have been observed. The authors report a case of bilateral subclavian steal syndrome through both vertebral arteries, the right common carotid artery, and the left internal mammory artery, without significant signs and symptoms of cerebral ischemia or anginal pain.- - - - - - - - - - ranking = 1keywords = artery, carotid (Clic here for more details about this article) |
2/554. Long-term successful coronary artery angioplasty in polycythemia vera.In a 65-year-old man with polycythemia vera, invalidating angina pectoris was associated with severe narrowing of the right coronary artery. After percutaneous coronary angioplasty (PTCA) the patient became symptom free and remained so for 12 months, while receiving an antiplatelet agent, a calcium antagonist and nitrate. coronary angiography repeated after a year, because of reappearance of angina, documented good patency of the treated artery and some progression of a narrowing involving another coronary vessel. This is the first reported case of long-term success of PTCA in polycythemia vera, a disease exposed to a high risk of thrombosis and, possibly, of restenosis. It is undefined whether medical treatment contributed to the anatomical and clinical results. As far as a single case can say, polycythemia vera might not represent a prohibitive background for coronary PTCA.- - - - - - - - - - ranking = 1.1994406701937keywords = artery (Clic here for more details about this article) |
3/554. Bifurcating aneurysm of the left main coronary artery involving left anterior descending and left circumflex arteries--a case report.Coronary artery aneurysm is a rare coronary abnormality, usually diagnosed incidentally by coronary angiography. Major causes of coronary aneurysms include coronary ectasia, Kawasaki disease, and atherosclerosis. Most of the discrete coronary aneurysms are of atherosclerotic origin. The incidence of atherosclerotic coronary aneurysms is about 0.2%, and the left main coronary artery is the least frequently involved artery. Only a few cases of left main coronary artery aneurysm have been reported in the literature, and a left main coronary artery aneurysm involving the proximal segments of the left anterior descending and the left circumflex arteries has not been reported previously. The authors describe this finding in a man who presented with worsening exertional angina pectoris. coronary angiography demonstrated an aneurysm of the distal left main coronary artery extending into the proximal segments of the left anterior descending and the left circumflex arteries. In addition, a significant flow-limiting atherosclerotic lesion was present in the proximal portion of the left anterior descending artery distal to the aneurysm.- - - - - - - - - - ranking = 2.3570992352077keywords = artery, atherosclerosis (Clic here for more details about this article) |
4/554. Retrograde embolization during saphenous vein graft angioplasty.angioplasty of degenerated saphenous vein grafts is not infrequently complicated by distal embolization of atheromatous debris. We describe an uncommon case in which balloon angioplasty of an old vein graft to a second diagonal branch of the left anterior descending coronary artery was followed by distal embolization. However, the embolization occurred in a retrograde fashion distal to the anastomotic site, resulting in occlusion of the upstream first diagonal branch. The reasons for its occurrence are discussed, together with suggestions for its recognition.- - - - - - - - - - ranking = 0.19990677836561keywords = artery (Clic here for more details about this article) |
5/554. Coronary ostial patch angioplasty in children.Patch angioplasty for coronary artery ostial stenosis was first reported in adults in 1952 and only sparsely used until 1983 when Hitchcock reviewed the technique in adults. We present two cases that highlight our use of this technique in inflammatory diseases of the aorta in children. Patch angioplasty restores physiologic perfusion of the coronary artery tree, preserves conduit material for further procedures later in life, and allows subsequent percutaneous transluminal coronary angioplasty of stenosis. For these reasons we believe that patch angioplasty holds undoubted advantage over the available alternatives.- - - - - - - - - - ranking = 0.39981355673122keywords = artery (Clic here for more details about this article) |
6/554. Multivessel spontaneous coronary artery dissection in a patient with severe systolic hypertension: a possible association. A case report.Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial ischemia and infarction. hypertension has not been associated with SCAD. The authors report multivessel SCAD in an elderly woman with severe systolic hypertension. They postulate that hypertension of this degree may play a pathophysiologic role in the causation of SCAD.- - - - - - - - - - ranking = 0.99953389182806keywords = artery (Clic here for more details about this article) |
7/554. pseudoxanthoma elasticum of the internal mammary artery.A case of pseudoxanthoma elasticum of the left internal mammary artery from a 61-year-old male who underwent coronary artery bypass grafting is reported. Intraoperative evaluation of the left internal mammary artery revealed partial stenosis. Histologically, the stenotic portion showed pseudoxanthoma elasticum. This represents the first reported case of pseudoxanthoma elasticum in the internal mammary artery.- - - - - - - - - - ranking = 1.5992542269249keywords = artery (Clic here for more details about this article) |
8/554. Multiple spontaneously occurring coronary artery-left ventricular communications: a case report.A search of the literature revealed that spontaneous coronary artery-left ventricular communications have only rarely been reported. These fistulae are frequently associated with angina pectoris which has been attributed to a ventricular steal phenomenon. The patient described herein presented with angina pectoris and was found to have multiple coronary arterioventricular communications without significant coronary atherosclerosis.- - - - - - - - - - ranking = 1.157658565014keywords = artery, atherosclerosis (Clic here for more details about this article) |
9/554. Supraarterial decompression myotomy for myocardial bridging in a child.A 10-year-old boy presented with a history of exertional chest pain. An electrocardiogram demonstrated an inferior apical myocardial infarction. Cardiac catheterization revealed myocardial bridging of the left anterior descending coronary artery with evidence of intramyocardial obstruction during systole. The patient underwent successful treatment with supraarterial decompression myotomy and remains symptom free at 1 year.- - - - - - - - - - ranking = 0.19990677836561keywords = artery (Clic here for more details about this article) |
10/554. Long non-iatrogenic right coronary artery dissection in stable angina pectoris treated with stenting.An extensive spontaneous right coronary artery dissection was the only abnormal angiographic finding detected in a 67-year-old man with chronic exercise-induced angina pectoris. The lesion was treated with multiple stenting with good angiographic results. The clinical implications of this finding and the details of the intervention performed are discussed in light of published data concerning this increasingly recognized angiographic entity.- - - - - - - - - - ranking = 0.99953389182806keywords = artery (Clic here for more details about this article) |
