The influence of pre-operative anaemia on clinical outcomes following infra-inguinal bypass surgery.
Anemia is associated with greater mortality and complications in cardiovascular surgery. Within chronic limb-threatening ischemia, the effect of anemia is becoming apparent. This study aimed to further understand the influence of anemia in patients undergoing surgical revascularization for lower limb ischemia. ⋯ Preoperative anemia in infrainguinal bypass surgery has a significant association with mortality and morbidity. Preoperative anemia should prompt the vascular team to consider these patients as high risk and consider optimization of Hb.

Ultrasound-enhanced catheter-directed thrombolysis (UET) using the Ekosonic® Endovascular System device for acute, peripheral arterial ischemia has been purported in clinical trials to accelerate the fibrinolytic process to reduce treatment time and lytic dosage. We aim to describe outcomes of UET in a real-world clinical setting. ⋯ UET with the EKOS device demonstrates acceptable real-world outcomes in the treatment of acute limb ischemia. UET is generally safe and effective at re-establishing in-line flow to yield high limb salvage rates. However, UET is associated with a high rate of reintervention. Further investigation is needed into specific predictors of limb salvage and need for reintervention, as well as cost-efficacy of this technology compared with that of traditional methods.

Case Reports
Severe Acute Respiratory Syndrome Coronavirus 2 Infection and the Upper Limb Deep Vein Thrombosis Risk.
Little or nothing is known about the correlation between the upper limb deep vein thrombosis (UL-DVT) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We describe the increased risk of UL-DVT in 3 patients with SARS-CoV-2 who require continuous positive airway pressure with a hood and the need for early adequate antithrombotic prophylaxis.

Comparative Study
High Prevalence and Mortality Associated with Upper Extremity Deep Venous Thrombosis in Hospitalized Patients at a Tertiary Care Center.
Upper extremity deep venous thrombosis (UEDVT) and its associated complications are increasing in incidence, but management strategies are largely derived from experience treating lower extremity deep venous thrombosis (LEDVT). The purpose of this study is to examine our single institution's experience with in-hospital venous thromboembolism (VTE), specifically the characteristics and outcomes of the UEDVT population as it compares to LEDVT. ⋯ This study demonstrates a high prevalence of UEDVT in hospitalized patients who experience VTE. Despite a lower incidence of synchronous PE, patients with UEDVT had a higher prevalence of significant medical comorbidities and higher all-cause mortality on the index hospital admission.

Comparative Study
Management and Outcomes of Isolated Axillary Artery Injury: A Five-Year National Trauma Data Bank Analysis.
The aim of this study is to evaluate recent national trends in the clinical characteristics, management, and outcomes of patients with isolated axillary artery injuries. ⋯ Axillary artery injury is more often caused by penetrating trauma. Despite introduction of novel endovascular techniques, the majority of patients with isolated axillary artery injury are managed using open repair. Penetrating axillary artery injury is significantly more likely to be managed using open repair and by surgical occlusion. Patients with blunt injury have higher complication rates and longer hospital length of stays. The mortality rate is lower than previously published.
