Bacterial endarteritis is rare and usually affects the abdominal aorta. A case of bacterial left subclavian arteritis complicated by mycotic aneurysm is presented. An early diagnosis of infective arteritis was made based on a history of fever, sweats, rigors, and a progressive macular rash, polyarthralgia splinter haemorrhage (limited to the ...
Chou S M - - 1993
By selectively infiltrating and destroying the internal elastica of a major cerebral artery, Aspergillus fungus (Af) induces disruption and incipient dilatation of the vascular wall with or without inflammation. This unique pathogenetic mechanism of forming "true" fungal mycotic aneurysms (FMAs) was clearly demonstrated in a middle-aged adult male who died ...
Kallis P - - 1993
We report a case of rupture of an aneurysm of the noncoronary sinus of Valsalva with the tract of the fistula emerging through the tricuspid septal leaflet. This rare pathology created a diagnostic dilemma, as the direction of the jet of blood was alternating between the right atrium and the ...
Quah B S - - 1993
A 10-year-old girl with mild aortic regurgitation presented with cerebral infarction. Two-dimensional echocardiography showed vegetations on the septal wall of the left ventricular outflow tract without involvement of the aortic valve itself.

BACKGROUND AND PURPOSE: Patients with infective endocarditis may develop intracranial mycotic aneurysms. Whether these patients should undergo cerebral angiography followed by prophylactic surgery if an aneurysm is detected is an unresolved question. METHODS: We estimated the probability of survival 12 weeks after the diagnosis of infective endocarditis on the basis ...
Humphreys J D - - 1992
Congestive heart failure developed in a 53-year-old man with a history of bicuspid aortic valve, angina, and pericarditis. Two-dimensional echocardiography showed a sinus of Valsalva aneurysm related to the anterior coronary sinus and color flow mapping identified a perforation of the anterior aortic cusp. These findings were confirmed during surgery.
Zwas S T - - 1992
Aortic arch mycotic aneurysm, an uncommon cause of sepsis, carries a grave prognosis. Clinical presentations as well as laboratory and radiologic examinations may be noncontributory and often misleading. In a patient with a fever of unknown origin, only the radiogallium study could enable an accurate diagnosis and pinpoint the anatomic ...
Sundar A S - - 1992
A 37 year old man presenting with acute heart failure, hypotension, and acute renal failure was diagnosed by cardiac catheterisation and angiography to have the rare combination of congenital aneurysm of the non-coronary sinus of Valsalva rupturing into the right ventricle, and an anomalous origin of the right coronary artery ...
Chakravarty K - - 1992
The case is described of a patient with mycotic aneurysm of the aortic arch whose clinical and serological features were indistinguishable from those of systemic lupus erythematosus. Surgical resection and repair of the aneurysm resolved her clinical symptoms and the serological abnormalities.

Reports concerning unruptured, isolated aneurysms of one sinus of Valsalva are rare. These aneurysms usually protrude inside the heart and are very rarely extracardiac. We report 4 cases of isolated, unruptured extracardiac aneurysms of the noncoronary sinus of Valsalva. Clinical symptoms were nonspecific. Operation was performed by patch reconstruction of ...
Walls J T - - 1992
Neopulmonary artery stenosis may occur after the arterial switching procedure to correct transposition of the great arteries. One technique to reduce this complication is to use a single rectangular piece of autogenous pericardium to reconstruct two adjacent sinuses of Valsalva and maintain pulmonary artery size. The long-term effect of this ...

We report on the successful treatment of a patient with a mycotic aneurysm of the suprarenal aorta. The aorta was resected and reconstructed using an in-situ polytetrafluoroethylene graft with a side arm branch to the left renal artery. The use of polytetrafluoroethylene graft for aortic reconstruction after suprarenal mycotic aneurysm ...
D'Silva S A - - 1992
A patient with unruptured congenital aneurysm of the left coronary sinus of Valsalva presented with acute right-sided heart failure due to right ventricular outflow tract obstruction. The mechanism for such an acute presentation may have been a sudden increase in the size of the aneurysm. The surgical importance of this ...
Huang J J - - 1992
"Mycotic" aneurysm was originally described by Osler in 1885. It occurs in a normal or atherosclerotic artery from septic emboli in patients with infective endocarditis. However, now the term "mycotic" aneurysm is applied to all cases of aneurysms caused by any organisms. From September 1988 to November 1990, four cases ...
Gauto A R - - 1992
Early diagnosis and successful antimicrobial therapy have diminished the frequency of embolomycotic aneurysms, but infected aortic and small vessel aneurysms, arteriosclerotic plaques, and prosthetic grafts are becoming more common. A broad spectrum of pathogens, including Staphylococcus, Salmonella, Enterobacteriaceae, Pseudomonas aeruginosa, and some unusual organisms, are associated with this change. We ...
Carrel T - - 1992
Infection in the vascular tree remains one of the greatest challenges for vascular surgeons. Despite technical advances and newer antibiotics, the morbidity and mortality remain high. The following case report underlines the complex factors encountered in a 62-year-old alcoholic patient presenting with a "classical" history of mycotic aneurysmal disease who ...
Jeyamalar R - - 1991
Aneurysms of the sinus of Valsalva are uncommon disorders and are usually congenital in origin. When these aneurysms rupture into an intracardiac chamber, they may be silent initially but later give rise to progressive heart failure due to left or right shunting and aortic regurgitation. The mortality and morbidity in ...
Kan M N - - 1991
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 ...

Coexistence of vertebral osteomyelitis and lesions of the aorta is rare but may be lethal if not diagnosed promptly and treated effectively. We describe a patient who was treated at the Cleveland Clinic Hospital, and we review 69 additional cases reported in the literature. The native aorta was involved in ...
Gelabert H A - - 1991
Mycotic aneurysms of the suprarenal aorta are rare lesions, accounting for less than 1% of aortic reconstructions for aneurysmal disease. The bacteriology of these lesions differs from the infrarenal aneurysms and primarily consists of Gram-negative organisms. We report an unusual case of an 87-year-old man successfully treated for a ruptured ...
Wei J - - 1991
Two rare cases of nonpenetrating trauma-induced fistula from the right sinus of Valsalva to the right heart chambers are reported. Both were diagnosed preoperatively and operated on successfully. A transverse tear was found in the right sinus of Valsalva, just below the right coronary ostium, in both patients. The ragged ...
Eber B - - 1991
In a 49-year-old male with fever, dyspnea, and chest pain, thoracic x-ray revealed pneumonia with enlarged heart silhouette. Antibiotics were successful, pneumonia healed and complaints disappeared. Yet, during the following 3 months, echocardiography showed mild persistent pericardial effusion while in ECG both sinus tachycardia and ST-T changes were found suggesting ...
Blackshear J L - - 1991
We describe a patient with a large unruptured sinus of Valsalva aneurysm that was discovered incidentally. Transesophageal echocardiography was used to characterize the aneurysm preoperatively, and was helpful intraoperatively in assessment of the degree of native aortic valvular regurgitation after repair. The use of transthoracic echocardiography, contrast echocardiography, Doppler echocardiography, ...
Jebara V A - - 1991
Mycotic aneurysms of the extracranial carotid arteries are rare. We report a new case with a mycotic aneurysm of the carotid bifurcation associated with acute bacterial endocarditis of the aortic valve. A concomitant treatment of both lesions was performed. Twenty-six cases of mycotic aneurysms of the extracranial carotid arteries have ...
Robicsek F - - 1991
Recent studies indicate that eddy currents generated by the sinuses of Valsalva play an important role in the physiologic closure of the aortic valve. This process is briefly discussed and evidence is presented that this fact was well known and elaborated upon by the renaissance artist Leonardo da Vinci. This ...
Ellenbogen R G - - 1991
We describe a transfalcine approach to clipping and subsequently excising an expanding mycotic callosomarginal aneurysm. The patient had a devastating dominant (left) hemispheric spontaneous intracranial hemorrhage and was neurologically improving at the time of surgery nearly 2 months later. To avoid retracting the left hemisphere, we approached this left callosomarginal ...
Barbie R M - - 1991
Acute mycotic aneurysms of the ascending aorta following aortocoronary bypass are exceedingly rare. To our knowledge, there have been few reports of successful management. The central location of this lesion places it apart from acute or chronic mycotic aneurysms in general and enhances its lethality. The availability of ascending and ...
Werner K - - 1991
Mycotic aneurysms of the celiac artery are extremely rare, and in our review of the literature we found that in only one case was it due to infective endocarditis. In our case a 19-year-old female patient with culture-negative infective endocarditis presented with pain in the epigastric area. A celiac artery ...
Dazai Y - - 1991
Infective aneurysm showing dilatation of all three coronary sinuses of Valsalva due to infective endocarditis is extremely rare.

After cardiac transplantation, bacterial mediastinitis is a rare but dangerous early complication. Of the 113 patients who underwent heart or heart-lung transplantation at our hospital from August 1981 to April 1989, 8 developed purulent mediastinitis. Treatment involved surgical débridment, local irrigation, drainage, and high-dose systemic antibiotics. No patient died of ...
Wells R G - - 1991
A case of mycotic carotid artery aneurysm due to cervical lymphadenitis in a four-year old child is presented. Sonography and computed tomography (CT) demonstrated an irregular fluid-containing neck mass, similar in appearance to an uncomplicated abscess. Continuity with the carotid artery was suggested on sonography, and CT demonstrated intense contrast ...
Kaufman J L - - 1990
A mycotic femoral artery aneurysm developed in a diabetic man with bacteremia from a Staphylococcus aureus urinary tract infection. Because of severe concomitant congestive heart failure and hypothyroidism, surgical reconstruction of the femoral artery was deferred while the patient received an intensive course of intravenous nafcillin. This led to stabilization ...
