Introduction.Listeria monocytogenes is a rare etiology of infectious endocarditis with only 30 cases of prosthetic valve and about twice as many native valve infections described in the literature. We describe an unusual presentation of an endovascular embolic phenomenon with associated lower extremity mycotic aneurysm due to Listeria monocytogenes prosthetic aortic valve and aortic endograft i...

We report herein a case successful endovascular treatment with a stent-graft of a rare case of rapidly growing mycotic aneurysm of the left common carotid artery due to acute bacterial endocarditis after eradication of the infection. Infected mycotic aneurysms of the peripheral vasculature have been considered as a contraindication for stent-graft implantation because of the possibility of micr...

The authors report a rare case of cerebral hyperperfusion syndrome (HPS) following the excision of a mycotic aneurysm with superficial temporal artery-to-middle cerebral artery (STA-MCA) bypass. A 74-year-old woman with infective endocarditis presented with progressive cerebral infarction and subarachnoid hemorrhage due to a mycotic aneurysm, which was excised with a STA-MCA bypass. Postoperati...

A 19-year-old man with mitral valve endocarditis and prolapse, intracerebral and intracerebellar hematoma, and a mycotic cerebral aneurysm underwent emergency mitral valve replacement during minimal cardiopulmonary bypass (total priming volume, 800 mL; autologous retropriming, activated clotting time <300 seconds) 1 day after undergoing endovascular coil embolization of the aneurysm. Postoperat...

Aortic sinus aneurysms are uncommon; association with pseudocoarctation has not been previously recognized. Morgan Jones and Langley (1949) in a classic paper reviewed fortythree autopsy proven cases, added four new ones, and divided them into congenital and acquired types: of the total, twenty-five were congenital. Venning (1951) reported three additional cases and Falholt and Thomsen (1953) i...

Mycotic aneurysm is an established condition first identified in 1885 by Sir William Osler. It is linked to malignant endocarditis. With prevalence of 0.7-2.6% of all cases of aortic aneurysms, it is associated with a significant rate of mortality and morbidity. Physicians should be highly cautious, as diagnosis and effective treatment for this condition are difficult. The following is a case r...

The surgical approach to the repair of a ruptured sinus of Valsalva aneurysm can depend on the cardiac chamber into which rupture occurs. This report details the color flow Doppler images in two patients who developed a right sinus of Valsalva aneurysm to right atrial fistula owing to bacterial endocarditis. In both cases, the color flow Doppler image was superior to contrast aortography in ide...

A 60-year-old man with chronic myelomonocytic leukemia was admitted for bacterial meningitis. Initial cranial CT and CT angiography (figure, A) were normal. Four days after admission, the patient became comatose. A subsequent cranial CT (figure, B) revealed a subarachnoid hemorrhage, and CT angiography (figure, C) showed a newly developed aneurysm of the basilar artery. We diagnosed a mycotic a...

introduction The first mention of the clinical aspects of infectious endocarditis (IE) comes from French physician Jean François Fernel in the 16th century.1 However, appropriate treatment only started being implemented more than a century later, when the presence of microorganisms as the cause of the disease was identified.2 IE normally affects the native valves as a primary site, being the mi...
