Clostridium septicum is an anaerobic, motile, spore-forming, toxin-producing gram-positive bacillus that can lead to rapidly progressive gas gangrene due to the release of alpha toxin. Aortic aneurysm secondary to C. septicum infection is a rare condition with 60 cases reported in the literature; however, we have recently treated several patients with the condition in our large tertiary care and aortic center. ⋯ In the largest reported case series, only a small percentage of patients with C. septicum-infected aortic aneurysms survived >1 year. In the patients described, those who did not receive an operation had 100% mortality. Earlier recognition and prompt operation with appropriate antimicrobial therapy are needed to improve the outcome of patients diagnosed with this rare infection.

A diverse array of measures are used to evaluate academic physicians. One critical factor is the scholarly influence an author has on the research discourse within a field. The National Institutes of Health recently developed the Relative Citation Ratio (RCR) as a method to quantify the influence of published research. The aim of this study was to examine the academic influence of vascular surgeons using RCR within common vascular disease research fields. ⋯ Vascular surgeons exhibit a moderate academic influence in the field of aneurysmal disease but lag behind medical subspecialists in high-impact scientific contributions to the fields of PAD and DVT. Innovative strategies and collaborations are likely needed to increase the influence of vascular surgeons on the academic discourse of several vascular disease research fields.

Frailty syndrome confers a greater risk of morbidity and mortality after operative interventions. The aim of the present study was to assess the effect of frailty on the outcomes after carotid interventions, including both carotid endarterectomy (CEA) and carotid artery stenting (CAS). ⋯ Frailty syndrome was associated with morbidity and mortality among patients undergoing surgical interventions for carotid stenosis. In the present study, frailty was associated with significant mortality and morbidity for those who had undergone CEA but not for those who had undergone CAS. However, the present study was not designed to determine the optimal treatment of frail patients. Incorporating frailty status into the treatment algorithm (CEA vs CAS) might provide a more accurate risk assessment and improve patient outcomes.

Data regarding the treatment of tandem carotid artery lesions at the bifurcation and ipsilateral, proximal common carotid artery (CCA) are limited. It has been suggested that concomitant treatment with carotid endarterectomy (CEA) and proximal ipsilateral carotid artery stenting confers a high risk of stroke and death. The objective of this study was to evaluate the technique and outcomes of this hybrid procedure at a single institution. ⋯ In appropriately selected patients, concomitant CEA and ipsilateral carotid artery stenting can be safely performed in high-risk patients with a low risk of myocardial infarction, neurologic events, and perioperative mortality when careful surgical technique is used, using direct carotid access, and distal carotid clamping for cerebral protection before stenting.
