BACKGROUND: Mycotic aneurysm of the thoracic or thoracoabdominal aorta and infection of thoracic or thoracoabdominal aortic grafts are challenging problems with high mortality. In-situ reconstruction with cryopreserved allograft(CPA) avoids placement of prosthetic material in an infected field and avoids suppressive antibiotics or autologous tissue coverage. METHODS: Fifty consecutive patients with infection of a thoracic or thoracoabdominal aortic graft or mycotic aneurysm underwent resection and replacement with CPA from 2006 to 2016...

OBJECTIVE: After primary infection with Coxiella burnetii, patients may develop acute Q fever, which is a relatively mild disease. A small proportion of patients (1%-5%) develop chronic Q fever, which is accompanied by high mortality and can be manifested as infected arterial or aortic aneurysms or infected vascular prostheses. The disease can be complicated by arterial fistulas, which are often fatal if they are left untreated. We aimed to assess the cumulative incidence of arterial fistulas and mortality in patients with proven chronic Q fever...

Mycotic aortic aneurysms are exceedingly uncommon in infants and they have a high risk of rupture. Their surgical management is extremely challenging. We report a case of a 22-month-old girl who presented with abdominal pain and fever revealing a ruptured mycotic aneurysm of the infrarenal aorta. The surgical treatment consisted of a ligature of the proximal and distal ends of the aneurysm. Postoperative course was significant for hypertension. A year and a half follow-up showed no other complications. Limited data are available concerning our chosen technique, but the reported cases showed a good short-term outcome...

INTRODUCTION: Mycotic aortic aneurysm (MAA) is an uncommon cause of aneurysmal aortic disease. However, it may have an aggressive presentation and a complicated early outcome. Endovascular aneurysm repair (EVAR) of MAA is emerging as an alternative to open repair (OR) for the treatment of these aneurysms, particularly in high-risk surgical patients. We report a single-center experience with the endovascular management of mycotic aortic aneurysms. MATERIAL AND METHODS: Two mycotic abdominal aortic aneurysms were treated with an endovascular stent graft at Centre Hospitalier Régional du Val de Sambre, Belgium...

Mycotic aneurysm is a rare but life-threatening disease that warrants an integrated therapeutic approach involving surgical intervention and prolonged antibiotic use. However, the causative organisms are often unidentified because antibiotics started empirically render blood and tissue cultures negative. Molecular diagnosis has been reported to be useful in such culture-negative cases. We report a case of a culture-negative mycotic aortic aneurysm due to Haemophilus influenzae, diagnosed by direct 16S rRNA polymerase chain reaction (PCR) and sequencing of the resected aneurysm tissue...

A 43-day-old boy presented with bacteremia after umbilical artery catheterization. Duplex ultrasound examination revealed a 1.1- × 1.6-cm mycotic infrarenal aortic aneurysm and an incidental asymptomatic occluded right common iliac artery. Resection and repair were completed by creating an everted, double-layered internal jugular vein patch. Screening ultrasound examination 10 months postoperatively demonstrated successful repair.

OBJECTIVES: The outcome of endovascular repair (EVAR) for acute thoraco-abdominal aortic aneurysm (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...

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...

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.
