This study analyzed risk factors for mortality in peripheral arterial disease (PAD), including body mass index (BMI) and estimated glomerular filtration rate (eGFR). Risk factors for long-term survival are unclear in patients with PAD. The origin of the obesity paradox, a paradoxical decrease in mortality with increasing BMI, is also uncertain in these patients. ⋯ Low BMI, eGFR, CLI, and diabetes are significant risk factors for mortality in PAD. The obesity paradox was verified and may be partly explained by low BMI mediated by malnutrition and systemic inflammation due to PAD or chronic obstructive pulmonary disease.

Selective tibial revascularization refers to the practice of vessel repair vs ligation or observation based on factors observed at the time of injury. Although commonly employed, the effectiveness of this strategy and its impact on sustained limb salvage is unknown. The objective of this study is to define the factors most relevant in selective tibial artery revascularization and to characterize limb salvage following tibial-level vascular injury. ⋯ This report provides outcomes data for wartime tibial vascular injury, which supports a selective approach to tibial artery revascularization. Clinical factors such as ISS and degree of ischemia guide which patients are best suited for tibial vascular repair, while injury-specific characteristics are associated with amputation regardless of revascularization status.

Endovascular repair of blunt traumatic thoracic aortic injuries (BTAI) has become routine at many trauma centers despite concerns regarding durability and aortic dilatation in these predominantly young patients. These concerns prompted this examination of thoracic aortic expansion after endovascular repair of a BTAI. ⋯ During the first several years of follow-up, the proximal thoracic aorta dilates minimally after endovascular repair of BTAIs, with the segment just distal to the left subclavian artery expanding at a slightly greater rate. Longer-term follow-up is necessary to determine whether this expansion continues and becomes clinically significant.

Carotid endarterectomy (CEA) has been repeatedly described as a safe and efficacious procedure to provide a stroke-risk reduction benefit in both symptomatic and asymptomatic cases. Contemporary outcomes are acceptable using the large-scale randomized trials as a metric of success. Class I and II data can be applied to improve the care process of patients undergoing CEA. ⋯ Statins are beneficial to patients undergoing CEA with trials demonstrating up to a 3% absolute reduction in the incidence of stroke following CEA. Aspirin therapy is associated with an up to 7% absolute reduction in early stroke following CEA; however, the efficacy of combination or high-dose antiplatelet therapy remains ill-defined. A treatment strategy that involves perioperative medical optimization is likely to improve surgical outcomes and long-term cardiovascular risk for patients undergoing CEA.
