1/43. Staphylococcal coronary arteritis as a complication of septicemia.We describe a case of staphylococcal coronary arteritis in the setting of sepsis due to arteriovenous fistula and dialysis catheter infection. The left circumflex coronary artery was the only vessel involved. The patient was a 77-year-old, insulin-dependent diabetic man with chronic renal failure. The immunosuppressed state in diabetes with subsequent septicemia may have facilitated a large number of bacteria to lodge in the atheromatous plaque of the coronary artery. We briefly review previously reported cases and suggest that bacterial arteritis may be an underrecognized cause of acute coronary occlusion.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/43. Tracheocarotid artery fistula infected with methicillin-resistant staphylococcus aureus.Massive life-threatening haemorrhage from a fistula between the trachea and a major blood vessel of the neck is a rare complication of the tracheostomy procedure, well-recognized by anaesthetists and otolaryngologists. Although the lesion is likely to be encountered at autopsy, it is not described in histopathological literature. The possible causes are discussed together with the macroscopic and microscopic appearances of the lesion. Suitable procedures for its identification and for obtaining appropriate histopathological blocks are suggested. Presence of methicillin-resistant staphylococcus aureus (MRSA) has not been documented before and might have contributed to the genesis of the fistula in this case.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/43. Suprarenal mycotic aneurysm exclusion using a stent with a partial autologous covering.PURPOSE: To report a combined endovascular and open technique to manage a suprarenal mycotic aortic aneurysm using a stent-graft partially covered with a section of autologous artery. methods AND RESULTS: A 50-year-old was hospitalized for staphylococcal septicemia and severe back pain. A previously diagnosed 3-cm abdominal aortic aneurysm was found to have expanded 2 cm in 3 weeks. aortography documented some periaortic thickening and 2 mycotic aneurysms, one posterior at the level of the superior mesenteric artery and the second at the aortic bifurcation. After intensive antibiotic therapy, an endovascular approach to exclude the suprarenal mycotic aneurysm was undertaken in tandem with surgical excision of the infrarenal aneurysm. The harvested right common iliac artery was used to partially cover a Palmaz stent, which was deployed under direct vision just above the renal artery ostia so that the covered portion of the stent excluded the aneurysm. A right axillofemoral bypass with a femorofemoral bypass completed the revascularization. Postoperatively, the patient developed renal failure, ischemic colitis necessitating a left hemicolectomy, and paraplegia. Although the patient is paralyzed, the aneurysm remains excluded with patent visceral vessels at 12 months following surgery. No organisms were grown from excised aortic tissue, and no signs of recurrent infection have been seen. CONCLUSIONS: Stent-graft repair may be able to lessen the invasiveness and reduce the morbidity associated with treatment of mycotic aortic aneurysms.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/43. Infectious aneurysm clipping by an MRI/MRA wand-guided protocol. A case report and technical note.Infectious aneurysms are potentially deadly sequelae of multiple etiologies, typically associated with subacute bacterial endocarditis (SBE). Since these aneurysms tend to be distal, there are no consistent landmarks by which to localize them, in contrast to more typical aneurysms that occur on the circle of Willis or proximal, large cerebral vessel bifurcations. In addition, they tend to be extremely friable and may be obscured by blood if intracranial hemorrhage (ICH) has already occurred. These factors make clipping these aneurysms technically difficult, and searching for easily ruptured aneurysms without standard landmarks adds risk to the procedure. In this report, we describe the case of a 9-year-old boy with SBE and subsequent ICH secondary to a mycotic aneurysm. This aneurysm was localized to within millimeters by the MRI protocol described herein. The aneurysm was excised and the patient recovered without incident. Thus, MRI/MRA-guided frameless stereotaxy may be useful for localizing distal mycotic aneurysms, improving patient outcome by decreasing morbidity and mortality.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/43. Superficial lymphangitis with interface dermatitis occurring shortly after a minor injury: possible involvement of a bacterial infection and contact allergens.BACKGROUND: Linear supralymphatic eruptions with epidermal involvement have rarely been reported. OBJECTIVE: A search was made for apparent anatomical reasons and for external factors to explain the unique distribution pattern and clinical course in three cases in which the linear lesions occurred shortly after a minor injury. methods: Efforts to search for its etiology include careful outlining of the localization, bacterial culture from the site of traumatic injury, patch tests, and skin biopsies. RESULTS: Linear lesions developed along superficial lymphatic vessels and the presence of eczematous conditions around the injured sites and isolation of Staphylococcus aureus from the site were observed concomitantly. The histopathological findings showed interface dermatitis. CONCLUSION: Our cases provide a unique example of the combined effects of a bacterial infection and contact allergens in the development of the linear supralymphatic eruptions.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/43. Anti-MPO-ANCA-positive microscopic polyangiitis following subacute bacterial endocarditis.Although infectious agents such as Staphylococcus aureus have been implicated in the pathogenesis of Wegener's granulomatosis, the role of bacterial infections in the pathogenesis of other types of small-vessel vasculitides associated with antineutrophil cytoplasmic antibodies (ANCA) is less clear. We describe a patient who developed a non-granulomatous necrotising small vessel vasculitis and perinuclear ANCA (p-ANCA) directed against myeloperoxidase (MPO) after recurrent episodes of bacterial endocarditis due to Staph. aureus. Although cytoplasmic ANCA (c-ANCA) directed against proteinase 3 have been reported in single patients with bacterial endocarditis, to our knowledge this patient is the first reported case of an anti-MPO-ANCA positive systemic vasculitis following bacterial endocarditis.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
7/43. Unusual cases of infective endocarditis.We report 2 patients with unusual cases of infective endocarditis. The first patient had a large, mural vegetation on left ventricle that was diagnosed with transthoracic echocardiography; and the second patient had a large, mobile vegetation in the descending prosthetic aorta with an abscess cavity around the vessel, diagnosed by transesophageal echocardiography. This report confirms the usefulness of transthoracic and transesophageal echocardiography in the diagnosis and management of uncommon cases of endocarditis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/43. Management of infected femoral closure devices.An increase in infectious complications has been noted with the introduction of percutaneous femoral artery closure devices. We report five cases of infected groins and/or femoral arteries following angiographic procedures that were completed using the Perclose Suture Mediated Closure Device (Perclose). Each patient required drainage of the abscess and removal of the Perclose suture. Most patients required more extensive vascular reconstructive procedures. When these complications arise, we recommend expeditious drainage of the abscess, removal of the suture, and adequate exposure of the femoral artery to facilitate repair of the vessel.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/43. vitreous hemorrhage as the initial presentation of postoperative endophthalmitis.PURPOSE: To describe a patient with postoperative endophthalmitis whose only abnormal finding at presentation was a vitreous hemorrhage. DESIGN: Interventional case report. methods: A 68-year-old diabetic woman underwent cataract extraction with intraocular lens implantation in the left eye. Three days after surgery, she had painless loss of vision, minimal anterior chamber inflammation, and dense vitreous hemorrhage in the left eye. RESULTS: On the fourth postoperative day, significant anterior chamber inflammation developed with fibrin and a hypopyon. During vitrectomy with intravitreal antibiotic injection, an area of retinitis surrounding an eroded retinal blood vessel was found. Cultures of undiluted vitreous fluid grew coagulase-negative Staphylococcus organisms. The endophthalmitis resolved and 20 months later, her best-corrected visual acuity had improved to 20/40. CONCLUSION: Postoperative endophthalmitis may present as a vitreous hemorrhage, secondary to retinitis and erosion of a retinal blood vessel.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
10/43. fluorescein angiographic findings in an infected scleral buckle.This report presents fluorescein angiographic (FA) findings in a patient with scleral buckle infection. Ten days following scleral buckling surgery, FA demonstrated dilated choroidal vessels over the buckle with leakage of fluorescein into the subretinal space. Irregular diffuse scleral thickening was noted on the computed tomography (CT). The findings of focal choroiditis with dilated leaky choroidal vessels seen on FA, or diffuse scleral thickening demonstrated by a CT may aid in establishing the diagnosis of scleral buckle infection.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
