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
Outcomes and Predictors of Popliteal Artery Injury in Pediatric Trauma.
Popliteal artery injury (PAI) is a rare occurrence in pediatric patients with significant consequences. Delays in diagnosis lead to severe complications such as lifelong disability and limb loss. We sought to identify outcomes and clinical predictors of PAI in the pediatric trauma population. ⋯ A higher index of suspicion should be present for PAI in pediatric trauma patients presenting with a closed patella fracture/dislocation after blunt trauma. PVI is most strongly associated with PAI in penetrating trauma. Prompt recognition of PAI is crucial as there is a greater than 10% amputation rate in the pediatric population.

Comparative Study
Perioperative Outcomes of Lower Extremity Revascularization for Rest Pain and Tissue Loss.
Critical limb ischemia (CLI) is the clinical manifestation of severe peripheral artery disease presenting as rest pain (RP) and tissue loss (TL). Most studies compare CLI as a homogenous group with claudication with limited database studies specifically studying these differences. We hypothesize that CLI should be stratified into RP and TL because of significant differences in disease severity, comorbidities, and outcomes. ⋯ Patients with RP and TL have drastic differences that impact perioperative mortality and readmissions. TL is an independent predictor of 30-day morbidity and major amputation. The stratification of CLI into RP and TL can provide insight into variations in outcomes and provide a means to quantify the risks associated with the 2 manifestations of the disease.

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.

Although recent data on the treatment of thoracoabdominal aortic aneurysms (TAAAs) are promising, in some cases, the paravisceral segment of the aorta may not be suitable for a branched endograft due to space restrictions. A combination of a fenestrated aneurysm repair (FEVAR) with a thoracic aneurysm repair (TEVAR) may represent a feasible treatment option. The current investigation was performed to assess the stability of a fenestrated Anaconda device implanted into a set of thoracic endografts from different manufacturers. We then assessed our clinical results with the FEVAR/TEVAR combination. ⋯ The combination of a thoracic tube graft and a fenestrated Anaconda device is a viable option for the treatment of patients with Extent I or IV TAAAs with no adequate landing zone above the celiac trunk. Although pull-out testing has shown good stability with most assessed grafts, the thoracic devices with thicker Dacron membranes seemed to be especially suitable.
