1/230. aortitis with multiple aneurysms mimicking infective endocarditis.aortitis usually produces aortic insufficiency by aortic root dilation. In rare cases the inflammation may involve the aortic valve cusps, causing valvular insufficiency. A patient in whom aortitis produced valvular masses, with aortic and peripheral arterial aneurysms, embolic episodes and aortic insufficiency is described. Valve replacement for suspected infective endocarditis was complicated by homograft dehiscence and multiple false aneurysms. Although immunosuppression was successful in decreasing the patient's vasculitis, he became infected and died of complications of aspergillus infection.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |

3/230. Mycotic aneurysms of the tibioperoneal arteries.This case report describes a pediatric patient with mycotic aneurysms of both posterior tibial arteries and the right peroneal artery associated with an episode of endocarditis. To our knowledge, this case represents the first reported occurrence of multiple mycotic aneurysms of the tibioperoneal arteries. It is also unique in that the pathogen was brucella canis instead of the usual gram-positive pathogens associated with intravenous drug injection. Vascular reconstruction can be accomplished; however, management of this complex problem should be individualized.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
4/230. Mycotic aneurysm complicating staphylococcal endocarditis.OBJECTIVE: To emphasize the role of noninvasive diagnostic investigative methods and their importance in early detection of mycotic aneurysm related to staphylococcal endocarditis, and of monitoring therapy or identifying complications. patients AND methods: Two patients with mycotic aneurysm that developed as complications of staphylococcal endocarditis are presented. The first patient had mesenteric artery mycotic aneurysm and presented with sudden rupture one month after initial diagnosis of mitral valve infective endocarditis and completion of a full course of antimicrobial therapy. The second patient had multiple cerebral mycotic microaneurysms and presented with hemorrhagic cerebral embolization from aortic valve infective endocarditis. RESULTS: The first patient died because of ischemic cerebral edema 48 h after rupture of the mesenteric artery mycotic aneurysm and massive hemoperitoneum, which was treated surgically with distal ileal resection and ileostomy. The second patient was alive two years after prolonged antimicrobial therapy and aortic replacement to treat moderate aortic regurgitation and progressive left ventricular enlargement. CONCLUSIONS: Mycotic aneurysm is a rare complication of infective endocarditis but has a high mortality rate because of its early or late potential catastrophic rupture. diagnosis by noninvasive diagnostic imaging techniques of mycotic aneurysm before rupture would be beneficial for its treatment.- - - - - - - - - - ranking = 1.8333333333333keywords = aneurysm (Clic here for more details about this article) |
5/230. Visualization of mitral valve aneurysm by transesophageal echocardiography.This article describes the transesophageal echocardiographic findings in a patient with pathologically proven mitral valve aneurysm. This aneurysm probably occurred as a complication of aortic valve endocarditis. Transesophageal echocardiography showed a saccular structure attached to the left atrial side of the anterior mitral leaflet with systolic expansion and diastolic collapse, and its orifice was visualized with excellent resolution. Transesophageal echocardiography is a useful diagnostic tool for evaluation of mitral valve aneurysm.- - - - - - - - - - ranking = 1.1666666666667keywords = aneurysm (Clic here for more details about this article) |
6/230. subarachnoid hemorrhage due to septic embolic infarction in infective endocarditis.During antibiotic therapy, a 56-year-old man with a streptococcus bovis endocarditis developed an infarction of the right middle cerebral artery (MCA). Thirty hours after stroke onset, cranial computed tomography controls demonstrated a secondary subarachnoid hemorrhage, marked in the cistern of the right MCA. The latent period, cerebrospinal fluid analysis, angiographic and pathologic findings favor the assumption of a pyogenic arterial wall necrosis of the MCA due to a septic embolus. This pathomechanism of intracranial hemorrhage in infective endocarditis should be distinguished from a rupture of a mycotic aneurysm.- - - - - - - - - - ranking = 0.16666666666667keywords = aneurysm (Clic here for more details about this article) |
7/230. Recurrent endocarditis in silver-coated heart valve prosthesis.BACKGROUND AND AIM OF THE STUDY: In order to prevent prosthetic valve endocarditis (PVE), the implantation of a new silver-coated sewing ring has been introduced to provide peri- and postoperative protection against microbial infection. methods: A 56-year-old woman with aortic stenosis had elective replacement with a St. Jude Medical mechanical valve fitted with a silver-coated sewing ring (Silzone). The patient developed early PVE, which necessitated reoperation after one month. Despite a second Silzone prosthesis being implanted, the endocarditis recurred. During a third operation an aortic homograft was implanted, and after six months a fourth operation was performed for a pseudoaneurysm at the base of the homograft, in proximity to the anterior mitral valve leaflet. RESULTS: The diagnosis of PVE was confirmed by the presence of continuous fever, transesophageal echocardiography and growth of penicillin-resistant staphylococcus epidermidis from the valve prosthesis. CONCLUSION: The implantation of all prosthetic valves is encumbered with a risk of endocarditis. Although silver has bacteriostatic actions, the advantages of silver-coated prostheses in the treatment of this condition have yet to be assessed in clinical trials.- - - - - - - - - - ranking = 0.33739066146051keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/230. aneurysm of the pulmonary trunk with patent arterial duct.We present a 14-year-old female with a massive aneurysm of the pulmonary trunk occurring secondary to bacterial endocarditis of the patent arterial duct. Echo Doppler imaging, magnetic resonance and angiography confirmed the diagnosis. On intermediate follow-up after surgical correction, the echo studies and cardiac catheterization disclosed no residual lesions. The patient is now asymptomatic.- - - - - - - - - - ranking = 0.16666666666667keywords = aneurysm (Clic here for more details about this article) |
9/230. Chronic sternal wound infection and endocarditis with coxiella burnetii.Chronic q fever is most commonly associated with culture-negative endocarditis and less frequently with infection of vascular grafts, infection of aneurysms, hepatitis, pulmonary disease, osteomyelitis, and neurological abnormalities. We report a case of chronic sternal wound infection, polyclonal gammopathy, and mixed cryoglobulinemia in which q fever endocarditis was subsequently diagnosed. polymerase chain reaction analysis of the wound tissue was positive for Coxiella burnetii dna, and treatment of the endocarditis resulted in prompt healing of the wound. Chronic q fever can occur without epidemiological risk factors for C. burnetii exposure and can produce multisystem inflammatory dysfunction, aberrations of the immune system, and persistent wound infections.- - - - - - - - - - ranking = 0.16666666666667keywords = aneurysm (Clic here for more details about this article) |
10/230. Brucella-mediated prosthetic valve endocarditis with brachial artery mycotic aneurysm.A 39-year-old female with a Hall-Kaster mitral prosthesis developed fever, general malaise and arthralgia 15 years after valve replacement for rheumatic mitral valve disease. Prosthetic valve endocarditis was identified after serial laboratory, clinical and echocardiographic examinations. penicillin g (40 x 106 units/day, i.v.) gentamicin (240 mg/day, i.v.) was started as initial therapy. The patient showed no signs of recovery, and penicillin g was replaced with vancomycin (1,000 mg/day, i.v.). There was a gradual reduction in spiking fever, and prominent reductions in erythrocyte sedimentation rate and white cell count. Meanwhile, a tender and pulsatile mass developed in the anterior surface of the left arm; peripheral angiography yielded a diagnosis of brachial artery aneurysm. A successful aneurysmectomy with saphenous vein interposition was performed. Histopathology of the lesion revealed mycotic aneurysm. An initial control SAT for Brucella of 1/80( ) was found to increase. A detailed history showed the patient to have consumed unpasteurized dairy products. Doxycyline (200 mg/day, oral) co-trimoxazole (2,700 mg/day, oral) rifampicin (600 mg/day, oral) was administered to treat brucellosis. Later, doxycyline caused intolerable gastrointestinal side effects and was replaced by ciprofloxacin (1,000 mg/day, oral). Subsequently, the patient made an uneventful recovery within one week. Antibiotic treatment was continued for 12 months, with complete resolution of vegetation and paravalvular leakage. During a four-year follow up, the patient showed no signs of relapse.- - - - - - - - - - ranking = 1.1666666666667keywords = aneurysm (Clic here for more details about this article) |
