OBJECTIVES: The outcome of endovascular repair (EVAR) for acute TAAA is reported and the applicability of the t-Branch off the shelf (OTS) device is determined. METHODS: Interrogation of a prospectively maintained database identified all patients who underwent EVAR for acute TAAA between September 2012 (when the first non-elective t-Branch case was performed) and November 2015. Early and medium-term outcomes were analysed. Survival and re-intervention-free survival were calculated by Kaplan-Meier analysis...

Melioidosis is a frequently fatal infection caused by the Gram-negative bacillus Burkholderia pseudomallei endemic to Southeast Asia and Northern Australia. It is a rare imported pathogen in the United States and is a potential bioterror agent. We report the case of an 82-year-old previously healthy man who presented with 2 weeks of fever and epigastric pain after he returned from the Philippines. A diagnosis of nondissecting mycotic aneurysm in the descending thoracic aorta was made with the help of CT angiogram and positive blood cultures...

Introduction: Aortic endograft infection is a rare but serious complication following endovascular aneurysm repair. An unusual presentation associated with an uncommon organism is reported. Case report: A 69 year old female was prescribed but failed to complete a full course of co-amoxiclav following a forearm cat bite. Nine days later she was admitted with pyrexia, left flank pain, and haematuria. Empiric treatment for a urinary tract infection was started. Pasteurella multocida was isolated from blood culture performed during this attendance...

Background: Mycotic aortic aneurysms are rare and life-threatening. Unfortunately, no established guidelines exist for the treatment of patients with mycotic aortic aneurysms. The purpose of this study was to evaluate the midterm outcomes of the open repair of mycotic thoracic and thoracoabdominal aneurysms and suggest a therapeutic strategy. Methods: From 2006 to 2016, 19 patients underwent open repair for an aortic aneurysm. All infected tissue was extensively debrided and covered with soft tissue...

We describe the case of a 69-year-old man with a thoracic pseudoaneurysm caused by a diffuse large B-cell lymphoma. He had a large mass inside the aortic arch. Five weeks later, an asymptomatic aneurysm protruding from the minor curvature of the distal aortic arch was observed. We suspected a mycotic pseudoaneurysm and performed total arch replacement with an omental pedicle flap graft. Intraoperative tissue cultures and histopathologic tests identified no bacteria, however. Eventually, a pathologic examination revealed that the structure initially suspected to be an intramural thrombus was a diffuse large B-cell lymphoma...

Monitoring outcomes following endovascular aortic repair (EVAR) is critical. Although evidence from randomized controlled trials has solidified the role of EVAR, the analysis of outcomes and "real-world" data has uncovered limitations, improved the selection of appropriate patients, and underscored the importance of instructions for use. Subsequent studies demonstrated the learning curve of EVAR and gradual improvement of outcomes over time. Outcomes analyses will continue to play an important role, particularly as technological growth of endovascular therapy has enabled treatment of more complex aneurysm pathologies and patients...

We report a case of subarachnoid haemorrhage resulting from a mycotic aortic aneurysm in a child with CHD. The patient previously underwent operations for CHD and had a subarachnoid haemorrhage of unknown cause before the scheduled re-operation. During the re-operation, a sealed rupture of an undiagnosed mycotic ascending aortic aneurysm was identified, and the causative organism was later identified as Streptococcus. A postoperative MRI indicated a partially thrombosed cerebral aneurysm. This case demonstrates that a mycotic aortic aneurysm can be a cause of intracranial haemorrhage in children...

BACKGROUND: Mycotic aortic aneurysm (MAA) is a rare clinical entity with an incidence of 1-3%, but it is a life-threatening infection of aorta characterized by dilatation of aorta with false lumen. Multiple MAAs have been reported rarely with an incidence of 0.03% and associated with a high mortality rate of 80% if ruptured. CASE PRESENTATION: A hypertensive and diabetic 78-year-old man visited our emergency department complaining intermittent dull and tingled pain over the left flank region for 1 week...

A 71-year-old male with a past medical history of coronary artery bypass surgery developed multiple, infected pseudoaneurysms of the ascending aorta and aortic root 1 year after cardiac catheterization. He underwent aortic root replacement with a 24-mm homograft. Tissue culture from operative specimens revealed invasive Aspergillus fumigatus infection. He was treated with voriconazole for 3 months. After 1 year, he had no recurrence of symptoms, pseudoaneurysm, or fungal infection.

Abdominal aortic aneurysm (AAA) is an uncommon entity with high mortality. Etiologically, they are classified as inflammatory and infective (mycotic), the latter being less common. Clinical presentation, laboratory investigations, and treatment for these may considerably overlap. However, choice of management and the need for surgical intervention depends on factors such as size and progression of aneurysm, persistent symptoms, and presence or absence of distant pathology. Although computed tomography (CT) is the gold standard for AAA, in selected cases, especially in infected AAA, fluorodeoxyglucose positron emission tomography-CT can provide valuable information...

A 78-year-old man who had undergone aortic valve and ascending aorta replacements presented with fever and was referred to our hospital. Blood culture revealed Gram-positive cocci, thus antibiotic therapy was started. Brain magnetic resonance imaging showed fresh cerebral infarction without cerebral haemorrhage or mycotic aneurysm. Transoesophageal echocardiogram revealed a vegetation that was attached to the right coronary cusp. The patient underwent successful aortic valve neocuspidization using glutaraldehyde-treated bovine pericardium...

The term "mycotic aneurysm" was first used by Osler in 1882 to describe a mushroom-shaped aneurysm in subacute bacterial endocarditis. Mycotic aneurysms account for only 2.6% of all aneurysms of the aorta. Rarer still are anaerobic infections secondary to organisms such as Clostridium septicum, which results in emphysematous aortitis. The vast majority of emphysematous aortic infections occur as a result of instrumentation; however, in this case we present an infection de novo. A 75-year-old male presented with a 2-week history of progressive fatigue and chest pain that then developed into constitutional symptoms...

BACKGROUND: Endovascular repair for mycotic aortic aneurysm (MAA) is a less invasive alternative to open surgery, although the placement of a stent graft in an infected environment remains controversial. In this study, we developed hybrid biodegradable, vancomycin-eluting, nanofiber-loaded endovascular prostheses and evaluated antibiotic release from the endovascular prostheses both in vitro and in vivo. METHODS: Poly(D,L)-lactide-co-glycolide and vancomycin were dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol...

Pneumococcal mycotic aneurysms are rare and associated with significant mortality and morbidity. Early intravenous antibiotic therapy and surgical intervention is the mainstay of treatment. Pneumococci frequently autolyze in blood cultures, making microbiological diagnosis challenging. We present the case of a man in his mid 70s with multiple thoracoabdominal mycotic aneurysms. Surgery was performed to a threatening saccular aortic arch aneurysm. Samples were sent for microbiological analysis and all were culture negative...

The surgical outcomes in patients with mycotic aortic aneurysm are still poor. In situ reconstruction and extra-anatomical bypass are the 2 main surgical options used in these patients, both of which have postoperative complications: recurrence of infection and aortic stump blowout, respectively. We performed in situ reconstruction in 25 consecutive patients with mycotic abdominal aortic aneurysms together with extended debridement using an irrigation device, omental flap coverage, rifampicin-soaked prosthetic graft, and sufficient antibiotics administration...

Mycotic aneurysm of the aorta is a rare, but life-threatening pathology. In recent years, endovascular stent graft placement has been introduced as an effective alternative for treating infected aortic aneurysms. A 64-year-old woman with a history of paraplegia due to spinal cord injury was referred to our institute with fever and blood-tinged sputum. Computed tomography (CT) scan showed an 11-cm pseudoaneurysm arising from the proximal descending aorta, which was normal 1 month ago at the previous CT scan...
