2/80. Mycotic aneurysm presenting as Pancoast's syndrome in an injection drug user.Injection drug users frequently present to emergency departments with fever. A careful history and physical examination with attention to anatomic localization of symptoms and signs are often necessary to unmask unusual underlying medical conditions. We report a case of a woman with recent injection drug use who presented with fever, a palpable neck mass, and Pancoast's syndrome. She had been seen recently at the ED of another hospital and discharged with oral antibiotics for presumed cellulitis. A mycotic aneurysm of the subclavian artery causing Pancoast's syndrome was later diagnosed by using computed tomography and angiography. A high index of suspicion for anatomically localized infective processes should always be maintained with febrile injection drug users.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
3/80. Purulent pericarditis due to group B streptococcus and mycotic aneurysm of the ascending aorta: case report.A 61-year-old female, with a history of uterine and cervical cancer treated with radical hysterectomy and 2 years of postoperative chemotherapy, presented to the emergency department with dyspnea on exertion. Computed tomography of the chest revealed a large pericardial effusion and a sacciform aneurysm of the ascending aorta. The patient subsequently underwent emergency pericardiocentesis with drainage of approximately 330 ml of a bloody and turbid effusion. Cultures from the effusion yielded group B streptococcus. multiple organ failure and disseminated intravascular coagulation syndrome occurred in the acute phase, but gradually improved with continuous antibiotic therapy. On the 194th hospital day, in situ reconstruction of the ascending aorta was successfully performed using a synthetic graft. Although rarely reported, both purulent bacterial pericarditis and mycotic aneurysm can be life-threatening.- - - - - - - - - - ranking = 1.2keywords = aneurysm (Clic here for more details about this article) |
4/80. arteriovenous fistula secondary to iliac mycotic aneurysm: helical CT findings.We describe the case of a 59-year-old man who presented a mycotic aneurysm of the common right iliac artery due to streptococcus agalactiae and developed an arteriovenous fistula within the inferior vena cava secondary to spontaneous rupture of the aneurysm. The clinical syndrome, helical computed tomographic, and angiographic findings are described and discussed.- - - - - - - - - - ranking = 1.2keywords = aneurysm (Clic here for more details about this article) |
5/80. Unusual association: streptococcus bovis tricuspid endocarditis with atrial-septal aneurysm and patent foramen ovale.streptococcus bovis endocarditis is a frequent cause of streptococcal endocarditis and is associated with colonic tumours. The tricuspid valve is very rarely affected and its involvement is a complication which can lead to a less favourable outcome. We report the seventh case of tricuspid valve endocarditis due to S. bovis, and the first, to our knowledge, to be associated with an atrial-septal aneurysm and a patent foramen ovale. The underlying medical conditions and predisposing factors for development of tricuspid valve endocarditis are described and interesting new echocardiographic data are presented. The current guidelines on antibiotic therapy for S. bovis tricuspid valve endocarditis are reviewed.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
6/80. Mycotic pseudoaneurysm of the aorta in children.Mycotic pseudoaneurysm of the aorta is a rare disease in childhood. We report on two cases which were diagnosed in an unselected general pediatric population within an 8-month period. The first case was a 16-month-old toddler with a normal cardiac history who presented with purulent pericarditis due to group A streptococcus and subsequent pseudoaneurysm formation of the ascending aorta while convalescing from varicella infection. The second case was a 14-year-old girl with a previously undiagnosed coarctation of the aorta who developed a staphylococcus aureus aortitis in the dilated poststenotic segment with pseudoaneurysm formation and infiltration into the adjacent lung tissue. In both cases parenteral antibiotic therapy was administered over 10 and 4 days, respectively, followed by emergency surgery consisting of aneurysmectomy, coarctectomy (case 2), and in situ homograft implantation. Recovery was uneventful. In both cases early institution of a femorofemoral cardiopulmonary bypass prevented a fatal outcome despite intraoperative rupture of the pseudoaneurysm.- - - - - - - - - - ranking = 2.4628190195124keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
7/80. aortic aneurysm resulting from umbilical artery catheterization: case report, literature review, and management algorithm.Aortic aneurysms in infants and children are quite rare. The use of umbilical artery catheters in the management of critically ill neonates has been associated with infection and subsequent aneurysm formation. There have been 46 cases reported (including our own); most of the aneurysms have been located in the abdominal aorta and have displayed saccular morphology. Through an analysis of the literature, we identified two factors that had significant correlation with improved survival: diagnosis before surgery and surgical repair (P <.05). This report presents the case of a 23-day-old neonate with an abdominal aortic aneurysm and hypertension. On the basis of our literature review, we offer a management algorithm for this rare but very serious complication of umbilical artery catheterization.- - - - - - - - - - ranking = 1.6keywords = aneurysm (Clic here for more details about this article) |
8/80. Mycotic aneurysm of the palmar artery associated with infective endocarditis. Case report and review of the literature.A 26-year-old man was diagnosed with mycotic aneurysm of the left hand associated with active infective endocarditis. Preoperative arteriography of the hand revealed aneurysm of the radial side of the deep arch of the palmar artery. We approached the aneurysm from the dorsal side of the hand in order to avoid damage to the collateral vascular supply of the superficial arch of the palmar artery and neurological structures. As a result, the aneurysm was excised simply by proximal and distal ligation of the vessel. During follow-up over 14 months, no evidence of recurrent aneurysm formation or ischemia of the fingers has been obtained.- - - - - - - - - - ranking = 1.8keywords = aneurysm (Clic here for more details about this article) |
9/80. Massive hematuria due to right renal artery mycotic pseudoaneurysm in a patient with subacute bacterial endocarditis.A 40-year-old woman with recently diagnosed bacterial endocarditis was admitted to the hospital with gross hematuria and anemia. Computed tomography revealed a large right upper pole renal artery pseudoaneurysm, a wedge-shaped hypoperfused region of the left kidney, and a splenic abscess. Radiographic embolization of the right renal artery was performed to stabilize the bleeding. The splenic abscess was drained. Subsequent right nephrectomy and splenectomy were performed for persistent leukocytosis. This unusual presentation of a septic embolus and its management are discussed.- - - - - - - - - - ranking = 1.4142618871953keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
10/80. Successful treatment of a ruptured mycotic aneurysm of the ileocolic artery with transcatheter embolization and antibiotic therapy.We report a case of mycotic aneurysm of the ileocolic artery due to streptococcus bovis endocarditis and acute septicemia complicated by active hemorrhage, that was treated successfully with transcatheter embolization and subsequent intravenous antibiotic treatment. This case suggests that a mycotic aneurysm can be treated successfully by percutaneous embolization in an emergent situation (active bleeding, septicemia) even without previous antibiotic therapy.- - - - - - - - - - ranking = 1.2keywords = aneurysm (Clic here for more details about this article) |
