1/4. An unusual case of vegetative aortitis diagnosed by transesophageal echocardiography.We report a case of staphylococcus aureus aortitis in a 42-year-old man who had a fever, an embolus to the left upper arm, and positive blood cultures. Transesophageal echocardiography re-vealed a 3 x 1-centimeter polypoid mass attached to the intima of the medial wall of the aorta, just distal to the origin of the left subclavian artery. The clinical presentation and the transesophageal echocardiography findings led to the diagnosis of vegetative aortitis. Antibiotic therapy was begun, and 5 days later the mass was surgically excised to prevent the possible formation of an infective aortic aneurysm and embolization to the vital organs.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
2/4. Rapid progression of bacterial aortitis to an ascending aortic mycotic aneurysm documented by transesophageal echocardiography.A case of bacterial aortitis of the ascending aorta caused by staphylococcus aureus progressed to an aortic mycotic aneurysm. Transesophageal echocardiography was the diagnostic approach of choice. The different stages of the disease from the initial aortic wall infection to formation of an abscess that communicated with the aortic lumen were documented by transesophageal echocardiography.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
3/4. rupture of a nonaneurysmal aorta secondary to Staphylococcus aortitis.Infectious aortitis has become increasingly uncommon and, when diagnosed, typically occurs in an immunocompromised elderly male with a history of Staphylococcus or salmonella infection and underlying atheromatous cardiovascular disease. The authors report a case of a 74-year-old man with aortitis complicated by rupture secondary to staphylococcus aureus infection. The patient presented with worsening abdominal pain and fever after being discharged from the emergency room 2 weeks before with back pain and leukocytosis diagnosed as urinary tract infection and bronchitis. Computed tomography (CT) imaging of the retroperitoneum on the first visit appeared normal. Repeat CT scan on the subsequent visit revealed a contained rupture of a nonaneurysmal aorta at the level of the diaphragm. The patient was taken to the operating room emergently for repair. An infected periaortic hematoma and a 1 cm perforation in the posterior aorta were found. The aorta was excised and the area debrided. Revascularization was performed using a 22 mm extruded polytetrafluoroethylene (ePTFE) interposition graft placed in situ. This case demonstrates that a high index of suspicion is required in diagnosing infectious aortitis and that the diagnosis may be delayed in many cases. Additionally, it may not be uncommon for the infected aorta to rupture without prior aneurysm formation.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
4/4. Hemorrhagic cardiac tamponade: a clinicopathologic correlation.staphylococcus aureus pericarditis and recurrent episodes of hemorrhagic cardiac tamponade developed in a 31-year-old man. He later died of exsanguination and at autopsy was found to have a ruptured infective pseudoaneurysm of the aortic arch. When hemorrhagic pericardial effusions of undetermined cause are encountered, the heart and great vessels should be evaluated as potential sources of the hemorrhage.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
