1/59. Comparison of transesophageal to transthoracic color Doppler echocardiography in the identification of intracardiac mycotic aneurysms in infective endocarditis.We report on cases of mycotic aneurysms in a group of 14 patients with infective endocarditis, all of whom were evaluated with transthoracic (TTE) and transesophageal (TEE) color Doppler echocardiography. Four mycotic aneurysms were found, one each in the left ventricular outflow tract, the right coronary sinus of valsalva, the anterior mitral leaflet, and the atrial septum. With TTE, only three of four cases of mycotic aneurysms could be detected. Utilizing TEE, however, all were detected and their connections with the heart chambers or great vessels could be readily and clearly depicted, especially those in the atrial septum and mitral leaflet. We are of the opinion that TEE is superior to TTE in the identification and detailed analysis of mycotic aneurysms complicating infective endocarditis. In addition, we feel that echocardiography may help evaluate the progress of the disease, the location and direction of infection, and the extent of involvement of the mycotic aneurysms, providing useful information for guiding surgical intervention.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/59. Successful treatment of a ruptured mycotic coronary artery aneurysm.Documented mycotic aneurysms of the coronary arteries are unusual, and antemortem identification of such an aneurysm is rare. We present the case of a patient who had successful management of a ruptured mycotic aneurysm of a coronary artery.- - - - - - - - - - ranking = 6keywords = coronary (Clic here for more details about this article) |
3/59. Mycotic aneurysm of the ascending aorta following CABG.Mycotic aneurysm of the thoracic aorta is a rare and life threatening condition. Two patients are presented (both male, aged 66 and 59 years) in whom coronary artery bypass surgery was complicated by the development of a mycotic aneurysm. fever preceded the radiological and echocardiographic signs of the aneurysm by at least several months in both cases. blood cultures were negative for one patient and the source of corynebacterium sp infection in the other was not determined for several months. Both patients died before surgery could correct the aneurysm.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
4/59. Infrarenal mycotic pseudoaneurysm. A late complication of coronary bypass surgery with proximal aortic dissection.A 62-year-old man developed a mycotic infrarenal pseudoaneurysm at the re-entry site of a previous aortic dissection. The aortic dissection had occurred one year earlier while he was undergoing coronary bypass surgery. The patient was successfully treated with a Dacron bifurcation graft after the mycotic aneurysm had been sterilized. Causes and relationships of the mycotic pseudoaneurysm to aortic dissection and aortic balloon support are discussed.- - - - - - - - - - ranking = 5keywords = coronary (Clic here for more details about this article) |
5/59. Aortic arch (pseudo) aneurysm complicating cardiac catheterization.The development of an infected aortic (pseudo)aneurysm which occurred after placement of a coronary artery stent is reported. Complications of cardiac catheterization and coronary artery stent placement are infrequent and this complication has not yet been reported in the literature.- - - - - - - - - - ranking = 2keywords = coronary (Clic here for more details about this article) |
6/59. Intra-arterial thrombin injection of an ascending aortic pseudoaneurysm complicated by transient ischemic attack and rescued with systemic abciximab.thrombin injection as a means of inducing thrombus formation has recently received wide attention as an alternative treatment for pseudoaneurysm. We present a case of a 67-year-old man in whom a large mycotic pseudoaneurysm developed in the ascending aorta because of sternal osteomyelitis and mediastinitis after coronary artery bypass grafting. Transcatheter intra-arterial thrombin injection was performed, and it successfully induced pseudoaneurysm thrombosis. However, the procedure was complicated by a sudden transient ischemic attack caused by thrombus propagation into the cerebral circulation. Complete thrombus dissolution in the cerebral circulation with the resolution of neurologic symptoms was achieved by means of intravenous abciximab.- - - - - - - - - - ranking = 1.2792744556609keywords = coronary, circulation (Clic here for more details about this article) |
7/59. Carotid artery aneurysm of granulomatous origin.A native of the Western Caroline islands presented with a granulomatous aneurysm of the right common carotid artery measuring 7 to 8 cm, which was resected and replaced with a reversed segment of saphenous vein. Adequacy of the collateral circulation to the brain was established by occlusion of the common carotid artery with local anesthesia. This was followed by definitive operation with general endotracheal anesthesia and induced hypertension. Although tuberculosis was the most likely etiologic agent, sarcoid could not be ruled out. Granulomatous aneurysms of the common carotid are extremely rare, and if this case was sarcoid in origin, it is the first such case reported. Only one other similar aneurysm could be found in the literature. Of the various methods of reconstruction of the common carotid artery reported, autogenous reversed saphenous vein is recommended strongly.- - - - - - - - - - ranking = 0.13963722783046keywords = circulation (Clic here for more details about this article) |
8/59. subarachnoid hemorrhage as a result of fungal aneurysm at the posterior communicating artery associated with occlusion of the internal carotid artery: case report.BACKGROUND: Fungal or "true" mycotic aneurysms of the intracranial circulation are very rare. rupture of a fungal aneurysm is fatal in almost 100% of cases. CASE DESCRIPTION: We report a 65-year-old woman with a ruptured fungal aneurysm on the posterior communicating artery associated with occlusion of the internal carotid artery. She had a past history of gastric malignant lymphoma and subsequent granulocytopenia. She survived after surgical treatment including trapping of the aneurysm and a superficial temporal artery-to-middle cerebral artery bypass. CONCLUSION: Improved immune response at the time of the onset of subarachnoid hemorrhage, as well as additional vasoreconstructive surgery, may have contributed to favorable outcome after surgical treatment.- - - - - - - - - - ranking = 0.13963722783046keywords = circulation (Clic here for more details about this article) |
9/59. Endovascular management of a ruptured mycotic aneurysm of the innominate artery.Mycotic aneurysms of the innominate artery are infrequent lesions and, as such, represent challenging surgical problems. We describe herein a case of a ruptured mycotic innominate artery aneurysm, which developed after radical neck dissection and radiation therapy for tonsillar carcinoma. The aneurysm was successfully excluded from the systemic circulation with endoluminal placement of a covered stent, with efficacy confirmed by vascular imaging at 6 months follow-up. The patient suffered no permanent neurologic sequelae. Long-term follow-up and chronic antibiotic therapy will be necessary to avoid infection of the covered stent in this high-risk surgical patient.- - - - - - - - - - ranking = 0.13963722783046keywords = circulation (Clic here for more details about this article) |
10/59. Aortic pseudoaneurysm complicating sternal wound infection following CABG.Pseudoaneurysm of the ascending aorta following coronary artery bypass grafting is a rare complication. In this report we present two such cases. We were successful in repairing the false aneurysm and sternal dehiscence in one case. The clinical features, diagnosis and surgical management are discussed.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
