COVID-19 first appeared in Wuhan, Hubei Province, China, in December 2019. Thought to be of zoonotic origin, it has been named SARS-CoV-2 (COVID-19) and has spread rapidly. As of April 20, 2020, there have been >2.4 million cases recorded worldwide. ⋯ Those with more severe disease and with other risk factors, including increasing age, male sex, obesity, cancer, comorbidities, and intensive care unit admission, are at higher risk of these events. However, there is little international guidance on managing these risks in COVID-19 patients. In this paper, we explore the current evidence and theories surrounding thrombosis in these unique patients and reflect on experience from our center.

Multicenter Study
Index and follow-up costs of endovascular abdominal aortic aneurysm repair from the Endurant Stent Graft System Post Approval Study (ENGAGE PAS).
Trials for endovascular aneurysm repair (EVAR) report lower perioperative mortality and morbidity, but also higher costs compared with open repair. However, few studies have examined the subsequent cost of follow-up evaluations and interventions. Therefore, we present the index and 5-year follow-up costs of EVAR from the Endurant Stent Graft System Post Approval Study. ⋯ Costs associated with index EVAR are driven primarily by cost of operating room supplies, including graft components. Subsequent admissions are largely not aneurysm related; however, cost of aneurysm-related hospitalizations is higher than for nonaneurysm admissions. These data will serve as a baseline for comparison with open repair and other devices.

Developing competence in open aortic surgery is increasingly challenging in vascular surgery training programs. Although static cadaver models provide an opportunity for dissection and exposure, the lack of pulsatility limits further education in managing blood vessels. We developed an affordable pulsatile cadaver simulation model to improve training in open abdominal aortic surgery with the primary objective of determining whether it incorporated the fidelity required to teach critical surgical techniques. ⋯ The implementation of a pulsatile cadaver-based simulation model for abdominal vascular surgery has the potential to be both affordable and provide necessary haptics and fidelity for training fellows in critical abdominal vascular techniques.

The prognostic value of asymptomatic perioperative troponin rise in vascular surgery is unclear. We conducted this systematic review and meta-analysis to determine the significance of clinical and subclinical troponin elevation after vascular surgery. ⋯ Elevated postoperative troponin is strongly prognostic of worse survival and greater likelihood of MACEs after vascular surgery, regardless of whether symptoms of myocardial ischemia are present. These data support the benefit of postoperative troponin monitoring in identifying patients at increased risk of worse outcomes and who may be candidates for personalized preventive interventions.

Long-term safety concerns have been raised that the use of paclitaxel-coated balloons and stents is linked to excess mortality. Our objective was to compare outcomes in patients treated with paclitaxel vs uncoated devices and to analyze long-term mortality. ⋯ The use of paclitaxel-coated balloons and stents does not increase mortality compared with uncoated devices out to 3.5 years. Paclitaxel-coated devices can be used with continued caution, especially in patients at increased risk of restenosis. Further long-term studies are needed to determine the risk of late mortality.
