The global SARS-CoV-2/COVID-19 pandemic has required a reduction in nonemergency treatment for a variety of disorders. This report summarizes conclusions of an international multidisciplinary consensus group assembled to address evaluation and treatment of patients with thoracic outlet syndrome (TOS), a group of conditions characterized by extrinsic compression of the neurovascular structures serving the upper extremity. ⋯ Catheter-based interventions may also be considered for selected patients with central subclavian vein obstruction and threatened hemodialysis access in all pandemic phases, with definitive surgical treatment postponed. • Evaluation and surgical treatment for arterial TOS should be reserved for limb-threatening situations, such as acute upper extremity ischemia or acute digital embolization, in all phases of pandemic response. In late pandemic phases, surgery should be restricted to thrombolysis or brachial artery thromboembolectomy, with more definitive treatment delayed until pandemic conditions resolve.

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.

Multicenter Study Comparative Study Observational Study
The impact of age on in-hospital outcomes after transcarotid artery revascularization, transfemoral carotid artery stenting, and carotid endarterectomy.
Previous data showed superior outcomes of carotid endarterectomy (CEA) compared with transfemoral carotid artery stenting (TFCAS) in elderly patients because of an increased stroke risk in TFCAS-treated patients. Transcarotid artery revascularization (TCAR) with flow reversal was developed to mitigate the maneuvers at highest risk for causing stroke during TFCAS, such as manipulation of a diseased aortic arch and crossing of the carotid lesion before deployment of an embolic protection device. This study aimed to compare the association between age and outcomes after TCAR, TFCAS, and CEA. ⋯ TCAR is a relatively safe procedure regardless of the patient's age. The advantages of TCAR become more pronounced in elderly patients, with significant reductions in in-hospital stroke compared with TFCAS in patients ≥77 years old, independent of symptomatic status and other medical comorbidities. These findings suggest that TCAR should be preferred to TFCAS in elderly patients who are at high surgical risk.
