Mycotic aneurysms

Pankaj Aggarwal, Pravin Saxena, Anil Bhan
Coronary artery stent infection has been reported with both bare metal stent and drug eluting stent and can present as mycotic coronary artery aneurysm, pseudoaneurysm, myocardial abscess, pericarditis or exudative effusion. Infection at the site of coronary stent implantation is rare and is believed to result typically from either direct stent contamination at the time of delivery or transient bacteraemia from access site. Introduction of drug-eluting stent (DES) has led to a marked reduction in the problem of in-stent restenosis across all patient subsets and lesions complexities...

Clostridium septicum is a highly virulent pathogen which is associated with colorectal malignancy, hematological malignancy, immunosuppression, diabetes mellitus and cyclical neutropenia. Presentation may include disseminated clostridial infection in the form of septicemia, gas gangrene, and mycotic aortic aneurysms. We report the case of a 62-year-old female presenting with necrotizing fasciitis of her left thigh and subsequently developing rectal bleeding. While she was being treated with empiric antibiotics, her blood culture was found to be positive for C...

We present the case of a 60-year old woman with a ruptured thoraco-abdominal aortic aneurysm (TAAA). It was a Type IV TAAA in the Crawford Classification. A mycotic origin was suspected as she had a known history of lymphocytic lymphoma. She underwent thoraco-abdominal aortic replacement with a good surgical result. Histopathological examination revealed destruction of the aortic layers due to inflammatory lymphomatous aortic infiltration. The patient fully recovered.

Aortic mycotic aneurysms are a rare but life-threatening potential complication of infective endocarditis. Rapid deterioration of the vascular wall in highly focal areas makes these pseudoaneurysms particularly prone to rupture, resulting in uncontrolled aortic hemorrhage. While computed tomography angiography (CTA) is the imaging modality of choice for the evaluation of mycotic aneurysms, it is not routinely performed in patients with known or suspected infective endocarditis (IE). However, current valvular heart disease guidelines support the use of cardiac CTA in cases of IE and suspected perivalvular extension when there is inadequate or ambiguous visualization on echocardiography...

An elderly man presented with fever and evidence of Salmonella infection, and was diagnosed to have coexisting constrictive pericarditis and mycotic aneurysm of the aortic arch. Pericardiectomy was performed under cardiopulmonary bypass with good result. To avoid deep hypothermic circulatory arrest, an aorto-brachiocephalic bypass, instead of total arch replacement, was performed. This was followed by a staged carotid-carotid bypass, thoracic endovascular stent graft placement. He was subsequently treated with prolonged antibiotics, and inflammatory marker normalized afterwards...

OBJECTIVE: Intracranial infectious aneurysms (IIAs) are a rare clinical entity without a definitive treatment guideline. In this study, we evaluate the treatment options of these lesions based on our own clinical experience and review the current knowledge of therapy as portrayed in the literature. METHODS: We conducted a single-center retrospective analysis of all patients with an IIA and performed a systematic review of the literature using the MEDLINE database...

Thoracic endovascular aortic repair for thoracic aortic aneurysms is an accepted alternative to open surgery, especially in patients with significant comorbidities. The procedure itself has a low risk of complications and fistulas to surrounding organs are rarely reported. An 86-year-old patient was admitted to our hospital with gastro intestinal (GI) bleeding and a suspected aortoesophageal fistula. Eight months prior, the patient had undergone a stent graft repair of a mycotic thoracic aneurysm. Computerized tomography angiography and upper GI endoscopy confirmed an aortoesophageal fistula, which was treated by esophageal stenting...

Numerous case reports have highlighted the relationship between BCG therapy and development of systemic mycotic aneurysms but none have established a management algorithm in patients with suspected vascular dissemination of Mycobacterium bovis. Delay in diagnosis of this disease process will lead to delays in initiation of anti- mycobacterium treatment to prevent dissemination into other arterial beds and potentially complicate effective surgical treatment leading to aneurysmal rupture and other devastating vascular consequences...

To date, S. alactolyticus endocarditis complicated by middle cerebral artery aneurysm has not been reported. We describe the case of a 65-year-old female with a history of hypertrophic cardiomyopathy with left ventricular outflow tract obstruction presenting with confusion and a apical holosystolic murmur. Angiography of the brain identified new bilobed left middle cerebral artery aneurysm. Serial blood cultures grew S. alactolyticus, and aortic and mitral valve vegetation were discovered on transesophageal echocardiography...

Fungal prosthetic valve endocarditis is an extremely severe form of infective endocarditis, with poor prognosis and high mortality despite treatment. Candida albicans is the most common etiological agent for this rare but increasingly frequent condition. We present a case of fungal prosthetic valve endocarditis due to C. albicans following aortic and pulmonary valve replacement in a 38-year-old woman with a history of surgically corrected tetralogy of Fallot, prior infective endocarditis and acute renal failure with need for catheter-based hemodialysis...

Mycotic aortic aneurysms are rare occurrences and such aneurysms associated with Streptococcal pneumoniae are seldom seen in the current antibiotic era. We present the unusual case of a 68 year old healthy female with a Streptococcal mycotic abdominal aortic aneurysm of unknown etiology treated with antibiotics and open surgical intervention. Post-operative imaging revealed multiple new thoracic mycotic aortic aneurysms for which she was treated with thoracic endovascular aortic repair. Sequential abdominal and thoracic Streptococcal mycotic aortic aneurysms treated with a combination of open and endovascular surgery demonstrates a unique and rare case...

OBJECTIVE: Mycotic rupture of the arteries is a rare but deadly disorder. Current management typically involves open surgical repair. However, endovascular repair is a potential treatment that can be used to delay open repair, especially in acutely unstable patients. A case report and review of the literature was conducted to determine whether endovascular therapy could be a destination therapy for patients with arterial rupture secondary to infection. METHODS: We present the case of a 72-year-old man with a left common iliac artery aneurysm rupture secondary to Salmonella infection treated with endovascular therapy upon initial presentation...

Lemierre's syndrome is a rare life threatening condition characterized by internal jugular vein thrombosis, and is typically associated with a gram negative infection with septic metastasis secondary to a retropharyngeal abscess that involves the vasculature of the head and neck. We report a case of Lemierre's syndrome in an 18-year-old female adolescent who developed an internal carotid artery occlusion and ipsilateral external carotid artery mycotic aneurysm complicated by fulminant pseudomonal sepsis. The patient was managed with open ligation of the external carotid artery with essentially complete recovery...

A 69-year-old male patient who was treated with intravesical BCG for carcinoma in situ of the bladder, went on to develop systemic features of BCG-osis. This diagnosis was supported by significant radiological and clinical findings. These systemic features include pulmonary miliary lesions, a mycotic abdominal aortic aneurysm and penile lesions. Owing to a breakdown in the relationship between the patient and the National Health Service, the patient has declined BCG treatment. This case highlights the potential rare side effects of intravesical BCG treatment and the risk associated with non-treatment of BCG-osis...

Rothia aeria is a Rothia species from the Micrococcaceae family. We report here the first French R. aeria endocarditis complicated by brain haemorrhage and femoral mycotic aneurysms. Altogether, severity and antimicrobial susceptibility should make us consider the management of R. aeria endocarditis as Staphylococcus aureus methicillin-susceptible endocarditis.

We report a case of a 15-year old boy who was managed as a case of B cell lymphoblastic leukaemia with the modified BFM 90 protocol. During the induction phase, he developed febrile neutropenia with sino-pulmonary fungal infection confirmed on histopathology. He developed left sided hemiparesis during in-hospital management of febrile neutropenia. Neuroimaging revealed 9.6 × 8.4 mm round well defined aneurysm arising from right cortical artery in distal middle cerebral artery territory. He underwent fronto-temporo-parietal craniectomy with evacuation of the hematoma and excision of the aneurysm...
