Background. Intravesicular Bacillus Calmette-Guérin (BCG) is an effective adjunctive therapy for superficial bladder cancer that has been shown to delay recurrence and progression of disease. Serious side effects are relatively rare but are difficult to diagnosis and commonly overlooked. Case Presentation. We report the case of a patient who was found to have mycotic aortic aneurysms secondary to treatment with BCG after a prolonged course with multiple intervening hospitalizations. Conclusion. Through this report, we discuss our present understanding of BCG infection following treatment and review the literature regarding this particular rare manifestation...

We report a case of ruptured mycotic thoracic aortic aneurysm treated with a pedicled latissimus dorsi flap after stent-graft implantation. The patient was a 64-year-old woman with diabetes mellitus that had developed septicemia as a result of pyelonephritis and a perinephric abscess. The patient required emergency stent-graft implantation due to rupture of an infected thoracic aortic aneurysm on hospital day 10. On hospital day 19, the abscess cavity was debrided and irrigated, and a pedicled latissimus dorsi flap was created...

Mycotic aneurysms and prosthetic graft infections are traditionally treated with excision of the infected tissue or graft, often requiring anatomical or extra-anatomical bypass, carrying significant morbidity and mortality. Currently, the role of endovascular repair without excision in this setting has yet to be defined. We present two case scenarios whereby mycotic pseudoaneurysms were successfully treated with endovascular stent graft coverage, and to present an in-depth review of endovascular in-situ revascularziation in the treatment of arterial and graft infections...

BACKGROUND: Adjuvant therapy with bacillus Calmette-Guerin (BCG), a live attenuated strain of Mycobacterium bovis, has become the treatment of choice for low-risk superficial bladder carcinoma following transurethral resection of the bladder. Complications following vesical BCG instillations are uncommon but, in some cases, severe side-effects can occur such as sepsis or mycotic aneurysm. Besides usual laboratory techniques used for the diagnosis of Mycobacterium tuberculosis complex (MTBC) infections (smear microscopy and cultures), commercial immunochromatographic assays detecting MBP64, a 24 kDa M...

A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

BACKGROUND: Disseminated invasive aspergillosis is an exceptional finding in immunocompetent hosts. As in immunocompromised patients, it has high mortality rates. Early diagnostic methods are required in order to properly manage the patient. Bis(methylthio)gliotoxin (bmGT) is a novel biomarker, useful in onco-hematological patients. CASE REPORT: A 70-year-old male, with non-insulin dependent type II diabetes mellitus and a past surgery history of aortic valve replacement with coronary by-pass five years ago, was seen in the emergency department with blurred vision...

An 82-year-old Japanese man, who presented with a fever and abdominal pain, was admitted to our hospital. According to enhanced computed tomography images, the probable diagnosis was abdominal aortic mycotic aneurysm. Eight sets of blood cultures obtained from the patient were negative. Despite administering treatment with vancomycin and ceftriaxone, the aneurysm progressively enlarged. He underwent open debridement surgery and in situ replacement because of an aneurysmal rupture. Bacteroides fragilis was isolated from the tissue culture of the aortic wall...

BACKGROUND: Alloplastic aortic graft infection is a devastating complication following aortic surgery. It is associated with excessively high mortality and morbidity caused by anastomotic rupture or septicemia. Many authors consider in situ replacement after complete surgical graft removal as the method of choice. However, there is an ongoing debate about the most suitable material for reconstruction. We present our first experiences with replacing the descending and infrarenal aorta using custom-made bovine pericardium grafts...

Mycotic abdominal aortic aneurysms (MAAAs) are rare entities accounting for 0.65-2% of aortic aneurysms. Campylobacter fetus has a tropism for vascular tissue and is a rare cause of mycotic aneurysm. We present a 73-year-old male patient with contained rupture of a MAAA caused by C. fetus, successfully treated with endovascular aortic repair (EVAR) and antibiotics, which is not previously described for this aetiology. Although open surgery is the gold standard, EVAR is nowadays feasible and potentially represents a durable option, especially in frail patients...

Mycotic aneurysm is an established condition first identified in 1885 by Sir William Osler. It is linked to malignant endocarditis. With prevalence of 0.7-2.6% of all cases of aortic aneurysms, it is associated with a significant rate of mortality and morbidity. Physicians should be highly cautious, as diagnosis and effective treatment for this condition are difficult. The following is a case report of a 13-year-old pediatric patient diagnosed with mycotic aneurysm. Before an adequate treatment plan could be developed and implemented, patient's status worsened swiftly and was ultimately terminal...

BACKGROUND: No reliable comparative data exist between open repair (OR) and endovascular aneurysm repair (EVAR) for mycotic abdominal aortic aneurysms (MAAAs). This nationwide study assessed outcomes after OR and EVAR for MAAA in a population-based cohort. METHODS: All patients treated for MAAAs in Sweden between 1994 and 2014 were identified in the Swedish vascular registry. The primary aim was to assess survival after MAAA with OR and EVAR. Secondary aims were analyses of the rate of recurrent infections and reoperations, and time trends in surgical treatment...

OBJECTIVE/BACKGROUND: The management of aortic graft infection (AGI) is highly complex and in the absence of a universally accepted case definition and evidence-based guidelines, clinical approaches and outcomes vary widely. The objective was to define precise criteria for diagnosing AGI. METHODS: A process of expert review and consensus, involving formal collaboration between vascular surgeons, infection specialists, and radiologists from several English National Health Service hospital Trusts with large vascular services (Management of Aortic Graft Infection Collaboration [MAGIC]), produced the definition...

Aortic infections are uncommon clinical entities, but are associated with high rates of morbidity and mortality. In this review, we focus on the cross-sectional imaging appearance of aortic infections, including aortic valve endocarditis, pyogenic aortitis, mycotic aneurysm and aortic graft infections, with an emphasis on CT, MRI and PET/CT appearance. Teaching Points • Aortic infections are associated with high morbidity and mortality. • CT, MRI and FDG PET/CT play complementary roles in aortic infection imaging...

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...
