1/65. Endovascular occlusion of a carotid pseudoaneurysm complicating deep neck space infection in a child. Case report.Pseudoaneurysm formation of the cervical internal carotid artery (ICA) is a rare, potentially lethal complication of deep neck space infection. This entity typically occurs following otolaryngological or upper respiratory tract infection. The pseudoaneurysm is heralded by a pulsatile neck mass, Homer's syndrome, lower cranial neuropathies, and/or hemorrhage that may be massive. The recommended treatment includes prompt arterial ligation. The authors present a case of pseudoaneurysm of the cervical ICA complicating a deep neck space infection. A parapharyngeal Staphylococcus aureus abscess developed in a previously healthy 6-year-old girl after she experienced pharyngitis. The abscess was drained via an intraoral approach. On postoperative Day 3, the patient developed a pulsatile neck mass, lethargy, ipsilateral Horner's syndrome, and hemoptysis, which resulted in hemorrhagic shock. Treatment included emergency endovascular occlusion of the cervical ICA and postembolization antibiotic treatment for 6 weeks. The patient has made an uneventful recovery as of her 18-month follow-up evaluation. Conclusions drawn.from this experience and a review of the literature include the following: 1) mycotic pseudoaneurysms of the carotid arteries have a typical clinical presentation that should enable timely recognition; 2) these lesions occur more commonly in children than in adults; 3) angiography with a view to performing endovascular occlusion should be undertaken promptly; and 4) endovascular occlusion of the pseudoaneurysm is a viable treatment option.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/65. Massive tracheal necrosis due to compression by an innominate artery aneurysm associated with a grade IV Chagasic megaesophagus and chronic duodenal ulcer.A 49-year-old man suffered necrosis of the cephalad tracheal segment due to compression by an innominate artery aneurysm. A peritracheal abscess, a grade IV chagasic megaesophagus, and a duodenal ulcer were also present. The patient underwent a three-stage surgical treatment, and 7 years later he is doing well, and breathing and eating normally.- - - - - - - - - - ranking = 0.12716507147039keywords = aneurysm (Clic here for more details about this article) |
3/65. Repair of a saccular aortic aneurysm with superficial femoral-popliteal vein in the presence of a pancreatic abscess.When one is faced with impending rupture, repair of an aortic aneurysm cannot be delayed. In the presence of coexisting intra-abdominal sepsis, traditional therapy would call for aneurysm exclusion and axillofemoral bypass grafting. Consequences of this choice of treatment include limited long-term graft patency and recurrent prosthetic infection. Autogenous deep veins from the lower extremities have demonstrated exceptional patency and resilience to infection when used to replace infected aortic grafts. We now report a case of concomitant open drainage of a pancreatic abscess and repair of a saccular abdominal aortic aneurysm using the superficial femoral-popliteal vein as a conduit.- - - - - - - - - - ranking = 0.17803110005855keywords = aneurysm (Clic here for more details about this article) |
4/65. Value of repeated multiplane transesophageal echocardiography in a patient with mitral valve ring abscess and left ventricular pseudoaneurysm.mitral valve ring abscess and ventricular pseudoaneurysm are rare complications of infective endocarditis. We describe the case of a 58-year-old man who was admitted to our hospital with sepsis caused by Staphylococcus aureus and in whom tricuspid and mitral valve endocarditis developed within 2 weeks. Despite widespread antibiotic therapy, the endocarditis proceeded to form a mitral valve ring abscess and a left ventricular pseudoaneurysm. The diagnosis was set by repeated multiplane transesophageal echocardiography and confirmed by heart surgery.- - - - - - - - - - ranking = 0.73092523927944keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
5/65. 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 = 0.6091043660662keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
6/65. Internal mammary artery pseudoaneurysms complicating chest wall infection in children: diagnosis and endovascular therapy.Mycotic internal mammary artery (IMA) pseudoaneurysms are sparsely reported in medical literature. We report imaging findings of IMA pseudoaneurysms secondary to chest wall abscesses (staphylococcal and tuberculous) in two children. Both children were successfully treated by endovascular method thus obviating the need for surgery.- - - - - - - - - - ranking = 0.73092523927944keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |

A pilot with pain in his leg: thigh abscess caused by salmonella enterica serotype Brandenburg.salmonella enterica serotype Brandenburg is one of the more uncommon serotypes isolated from patients with gastroenteritis. Few cases of extraintestinal infections with serotype Brandenburg have been documented. The first case of a serotype Brandenburg-dependent thigh abscess originating from an atherosclerotic pseudoaneurysm of the femoral artery is reported.- - - - - - - - - - ranking = 0.12182087321324keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/65. Sterile mediastinal gas mimicking abscess in aortic aneurysm repair.Six weeks after aortic aneurysm repair, computed tomography (CT) showed mediastinal gas where absorbable gelatin sponge (Gelfoam) was used. A leukocyte scan labeled with indium 111, however, was normal and surgical exploration showed no infection. Sterile gas collections may be seen following absorbable gelatin sponge use many weeks after surgery and 111In-labeled leukocyte scanning may be a useful differential test.- - - - - - - - - - ranking = 0.12716507147039keywords = aneurysm (Clic here for more details about this article) |
9/65. Conservative management of MRSA periaortic graft abscess.Following repair of ruptured abdominal aortic aneurysm a patient developed methicillin-resistant staphylococcus aureus perigraft abscess. The patient's clinical condition did not permit conventional open surgical correction. Ultrasound-guided aspiration and insertion of percutaneous drain enabled local antibiotic irrigation accompanied by systemic therapy. At 2 years follow-up the patient remains well with no evidence of sepsis.- - - - - - - - - - ranking = 0.025433014294078keywords = aneurysm (Clic here for more details about this article) |
10/65. Precordial abscess inducing chest pain 20 years after surgical repair of a pentalogy of fallot.A 25-year-old male asylum-seeker presented with chest pain, exertional dyspnea, and orthopnea 20 years after the surgical repair of a pentalogy of Fallot. An extracardiac mass compressing the right ventricle was subsequently detected and surgical decompression was performed to relieve the resulting right intraventricular hypertension. At operation, the mass proved to be a coagulase-negative, staphylococcal abscess. In addition, the removal of the mass unmasked a previously nonrecognized pulmonary outflow stenosis that required balloon dilatation and beta-blocker therapy. While infections are known to occur after sternotomy, the formation of an abscess in the anterior mediastinum several years after the intervention appears to be exceptional; this diagnosis came to mind only after the more common complications had been considered, e.g., pseudoaneurysm or pericardial hematoma. To our knowledge, this is the first report of an abscess in the anterior mediastinum that had probably formed over many years following a sternotomy, compressed the right ventricle and masked a pulmonary stenosis.- - - - - - - - - - ranking = 0.12182087321324keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
