1/132. Pseudoaneurysm following successful excimer laser coronary angioplasty of a restenotic left internal mammary artery graft ostial lesion.Although significant left internal mammary artery graft ostial stenosis is extremely rare, the clinical importance can be profound. In this report we describe a case in which a restenotic left internal mammary artery graft ostial lesion was successfully opened with excimer laser coronary angioplasty. A resulting pseudoaneurysm spontaneously closed after conservative therapy.- - - - - - - - - - ranking = 1keywords = graft (Clic here for more details about this article) |
2/132. Healing of the intimal dissection of the internal thoracic artery graft.We report healing of the intimal dissection of an internal thoracic artery graft. Triple coronary artery bypass grafting was performed using left internal thoracic artery and saphenous vein grafts. One month after operation, the intimal dissection of the internal thoracic artery graft was clearly visible by coronary angiography; however, after 1 year of only medical treatment consisting of warfarin, ticlopidine, and nitrate, the intimal dissection was undetectable by coronary angiography.- - - - - - - - - - ranking = 1.3333333333333keywords = graft (Clic here for more details about this article) |
3/132. Treatment of a coronary aneurysm with a new polytetrafluoethylene-coated stent: a case report.A 43-year-old man underwent implantation of a PTFE-covered stent to exclude an aneurysm in an aorto-coronary venous bypass graft. A successful aneurysm closure was achieved after high-pressure stent expansion and no intimal hyperplasia was observed within the PTFE-covered stent segment in the angiogram performed 9 months later. The technical characteristics and indications of this new coronary prosthesis are discussed based on the authors' recent experience in 63 patients.- - - - - - - - - - ranking = 0.16666666666667keywords = graft (Clic here for more details about this article) |
4/132. Obliteration of a coronary artery aneurysm with a PTFE-covered stent: endoluminal graft for coronary disease revisited.This is the first reported use of the JOSTENT stent graft for aneurysm disease in native coronaries. Consideration can be given to using this polytetrafluoroethylene (PTFE)-covered stent in situations such as dissections and restenosis in saphenous vein grafts or in long native coronary arteries without side branches, though further investigation is warranted.- - - - - - - - - - ranking = 1keywords = graft (Clic here for more details about this article) |
5/132. Sealing of coronary artery aneurysm by using a new stent graft.Coronary stenting has begun to play an increasingly important role in the management of coronary artery aneurysms. A case of successful and complete sealing of a coronary aneurysm by using a new stent graft is described. Further studies in a large patient population are required to confirm the safety and efficacy of this method. Cathet. Cardiovasc.

6/132. Coronary artery aneurysm after stent implantation.A coronary artery aneurysm that developed 6 months after coronary stent implantation in the left anterior descending artery, was treated by double coronary artery bypass grafting due to restenosis of the affected vessel and progression of right coronary artery stenosis. Although the poststenting aneurysm initially remained postoperative angiography showed that it had disappeared. In addition to thrombotic occlusion, another mechanism behind its disappearance may be that geometric changes of the implanted stent caused by heart retraction during surgery closed the entrance to the aneurysm.- - - - - - - - - - ranking = 0.16666666666667keywords = graft (Clic here for more details about this article) |
7/132. A large coronary artery saphenous vein bypass graft aneurysm with a fistula: case report and review of the literature.We describe a patient who developed a large aneurysm of saphenous vein graft to the right coronary artery with a fistulous communication to the right atrium. The presence of a fistulous communication of a saphenous vein graft aneurysm after coronary bypass surgery to one of the heart chambers is extremely rare. The diagnosis was made by coronary angiography and confirmed by CT and MRI. At surgery the aneurysm was ligated and excised. The fistula to the right atrium was closed. Repeat coronary artery bypass surgery with aortic valve replacement was performed at the same time without complications. Cathet. Cardiovasc.

8/132. Coronary artery aneurysm associated with fistula in adults: collective review and a case report.Coronary artery fistulae (CAF) are infrequent congenital anomalies. The combination of coronary artery aneurysms and coronary artery fistulae (coronary artery aneurysm associated with fistula, CAAAF) is extremely rare, and only 50 cases, including the current case, have been reported. Coronary artery fistulae may result in coronary ischemia, congestive heart failure, and endocarditis. Complications of coronary artery aneurysms include thrombosis, distal emboli, and aneurysm rupture. Aneurysm repair, fistulous closure and/or coronary artery bypass grafts are definite treatments for CAAAF. We present here a 72-year-old female with CAAAF. Furthermore, all reported CAAAF cases are reviewed.- - - - - - - - - - ranking = 0.16666666666667keywords = graft (Clic here for more details about this article) |
9/132. Surgical management of arteriosclerotic coronary artery aneurysm.A 60-year-old man suffered antero-septal myocardial infarction at the age of 56. coronary angiography demonstrated total occlusion of the left anterior descending artery and a large saccular aneurysm of the right coronary artery. Diffuse coronary ectasia was also shown in the right coronary artery adjacent to the aneurysm. Despite anticoagulant therapy, the aneurysm formed a thrombus and developed coronary artery stenosis distal to the aneurysm. ligation of the aneurysm and in situ gastroepiploic artery grafting were performed. Sudden heart failure was developed during skin closure. As this condition was considered to be graft hypoperfusion, supplemental saphenous vein grafting was placed. ligation is a simple, reliable technique to prevent future complications for a large saccular right coronary artery aneurysm, however, gastroepiploic artery might be an inappropriate bypass conduit for the ligated coronary artery with diffuse ectasia.- - - - - - - - - - ranking = 0.5keywords = graft (Clic here for more details about this article) |
10/132. Giant aneurysm of saphenous vein graft to coronary artery compressing the right atrium.Aneurysm of reverse aortocoronary saphenous vein graft is a known complication of coronary artery bypass grafting. In this report we present a case of a 60-year-old man who presented 12 years after coronary artery bypass grafting with a giant graft aneurysm of the reverse aortocoronary saphenous vein graft to the right coronary artery, compressing the right atrium. Spiral computed tomography was used to identify the aneurysm measuring 7 x 6 x 7 cm. We also reviewed the English-language literature and found reports of 50 patients with similar aneurysms of which 30 (61%) were identified as true aneurysms and 17 (33%) were identified as pseudoaneurysms. Three patients could not be identified into either group. We reviewed the presenting symptoms, diagnostic tools, and treatment options for this rare entity. An understanding of the pathophysiology of reverse aortocoronary saphenous vein graft aneurysm is important to prevent the possibility of aneurysm rupture, embolization, myocardial infarction, or death.- - - - - - - - - - ranking = 1.6666666666667keywords = graft (Clic here for more details about this article) |
