Enterococcus-related vascular graft infection: A case series.

Objectives: We aimed to assess the frequency, management, and burden of enterococcal-related vascular graft infection.

Patients And Methods: From 2008 to 2021, data regarding all episodes of vascular graft infections initially managed or secondarily referred to our referral center were prospectively collected. We described the history and management of the infection, depending on the type of prosthesis used.

Dalbavancin as suppressive therapy for implant-related infections: a case series with therapeutic drug monitoring and review of the literature.

Implant-related infections may need suppressive antibiotic therapy (SAT). We describe a SAT strategy using dalbavancin with therapeutic drug monitoring (TDM). This is a retrospective bicentric study of patients with implant-related infection who received dalbavancin SAT between January 2021 and September 2023.

Burden of Candida-related vascular graft infection: a nested-case control study.

Purpose: We aimed to assess risk factors of candida-related Vascular Graft Infections (VGIs).

Methods: We did a case-control study (1:4) matched by age and year of infection, nested in a cohort of patient with a history of VGIs. Cases were defined by a positive culture for Candida spp.

Tolerability of High Doses of Daptomycin in the Treatment of Prosthetic Vascular Graft Infection: A Retrospective Study.

Introduction: In treatment of prosthetic vascular graft infection (PVGI), appropriate antimicrobial treatment is crucial for controlling the septic process and preventing re-infection of the new graft. Glycopeptides are the mainstay of treatment for device-related infections by methicillin-resistant Staphylococcus aureus strains, but with some limitations, especially concerning vancomycin-intermediate and glycopeptide-intermediate S. aureus.

Factors predictive of treatment failure in staphylococcal prosthetic vascular graft infections: a prospective observational cohort study: impact of rifampin.

Background: There exists considerable debate concerning management of prosthetic vascular graft infection (PVGI), especially in terms of antimicrobial treatment. This report studies factors associated with treatment failure in a cohort of patients with staphylococcal PVGI, along with the impact of rifampin (RIF).

Methods: All data on patients with PVGI between 2006 and 2010 were reviewed.

Intra-abdominal aortic graft infection: prognostic factors associated with in-hospital mortality.

Background: Mortality associated with aortic graft infection is considerable. The gold standard for surgical treatment remains explantation of the graft. However, prognostic factors associated with early mortality due to this surgical procedure are not well-known.

Comparison of short- and mid-term follow-up between standard and fenestrated endografts.

Background: This study compared early and mid-term results of endovascular treatment for abdominal aortic aneurysms (AAAs) and pararenal aneurysms (PRAs).

Methods: Using data from a prospective database, patients treated with endografts for AAA and PRA between January 2007 and December 2009 were analyzed. In both groups, mortality, endoleak rates, evolution of renal function, reintervention rate at 30 days and at mid-term follow-up, and aneurysmal sac evolution at 1 year were compared.

Endovascular treatment of thoracoabdominal aortic aneurysms.

Background: Development in endograft design has extended endovascular treatment to include thoracoabdominal aortic aneurysms (TAAA). We report our experience using fenestrated and branched endografts in the management of TAAA.

Methods: We analyzed a cohort of consecutive patients treated electively for TAAA using endovascular techniques between 2006 and 2011.

Vascular graft infections.

Purpose Of Review: This review provides a focus on infections of prosthetic vascular grafts used to treat peripheral arterial diseases.

Recent Findings: The incidence of infections varies between 1 and 6%. Risk factors of infection are not well identified.

Fenestrated endovascular repair of type IV thoracoabdominal aneurysms: device design and implantation technique.

Treatment of thoracoabdominal aortic aneurysms has traditionally been by means of open surgery, but in recent years endovascular approaches have emerged as a viable and perhaps superior alternative. Some confusion appears to exist in discussions in the literature regarding the exact definition of the various types of thoracoabdominal aneurysm depending on whether open or endovascular repair is undertaken, with some authors comparing the preoperative extent of disease and others comparing the degree of aortic coverage required. Accurate preoperative planning and meticulous implantation technique are critical to successful outcomes with the endovascular approach.

Should we modify our indications after the EVAR-2 trial conclusions?

Background: To compare the results of the endovascular aneurysm repair (EVAR) in patients considered as unfit for surgery in a "high volume" center with the EVAR-2 trial results.

Methods: In our center, between January 2006 and December 2008, 469 endovascular aorta treatments were performed in high-risk patients. All the data were prospectively collected in a database.

Anatomic study of juxta renal aneurysms: impact on fenestrated stent-grafts.

Background: Fenestrated stent-grafts allow for treatment of patients with juxtarenal aneurysms (JRA) when they present with contraindications for conventional treatment. The fenestrated module is a custom-made module, specially designed to fit a specific patient, using computed tomographic scan measurements, which entails manufacturing delay and high cost. The aim of our study was to evaluate the possibility to reproduce the interrenal aorta anatomy to design a standard fenestrated module that would fit the maximum number of patients with JRA.

Inverted limbs in fenestrated and branched endografts.

Purpose: To describe our experience with the use of custom-designed branched or fenestrated endoprostheses incorporating an inverted contralateral limb in the bifurcated component.

Methods: Retrospective analysis was performed of a prospectively maintained database of all patients undergoing endovascular aneurysm repair using modular branched or fenestrated devices at a university teaching hospital between January 2004 and February 2010. Of 102 cases, 7 male patients (mean age 69 years) were treated with modular devices that incorporated an inverted contralateral limb in the bifurcated component.

Challenging treatment of a secondary endoleak in a fenestrated endograft.

Purpose: To describe the novel use of an Amplatzer occluder device to seal a secondary endoleak arising at a scallop in a fenestrated stent-graft.

Case Report: A 67-year-old man with comorbidities precluding standard endovascular repair of a pararenal aortic aneurysm was treated with a fenestrated endoprosthesis containing one fenestration for the left renal artery and one scallop for the celiac trunk; the right renal and superior mesenteric arteries were occluded at presentation. Interval imaging at 2 years showed a proximal type I endoleak at the celiac trunk scallop associated with expansion of the aneurysm sac.

Challenging catheterization of a branch in an endovascular thoracoabdominal aneurysm repair.

Purpose: To describe a novel technique of cannulating a side branch during endovascular repair of a thoracoabdominal aneurysm (TAAA).

Technique: The approach evolved during endovascular repair of a type III TAAA in which a custom-designed graft with 3 caudally directed branches was being deployed in a patient who had a prior surgical repair for a type IV TAAA. Two of the branches were successfully cannulated and stented, but repeated efforts to cannulate the left renal branch and artery via the standard brachial approach were unsuccessful.
