Coronavirus disease 2019 (COVID-19) is a novel coronavirus that has typically resulted in upper respiratory symptoms. However, we have encountered acute arterial and venous thrombotic events after COVID-19 infection. Managing acute thrombotic events from the novel virus has presented unprecedented challenges during the COVID-19 pandemic. In our study, we have highlighted the unique treatment required for these patients and discussed the role of anticoagulation for patients diagnosed with COVID-19. ⋯ We have described our experience in the epicenter of the pandemic of 21 patients who had experienced major thrombotic events from infection with COVID-19. The findings from our cohort have highlighted the need for increased awareness of the vascular manifestations of COVID-19 and the important role of anticoagulation for these patients. More data are urgently needed to optimize treatment and prevent further vascular complications of COVID-19 infections.

Little is known about the arterial complications and hypercoagulability associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We sought to characterize our experience with arterial thromboembolic complications in patients with hospitalized for coronavirus disease 2019 (COVID-19). ⋯ Patients with SARS-CoV-2 are at risk for acute arterial thromboembolic complications despite a lack of conventional risk factors. A hyperinflammatory state may be responsible for this phenomenon with a preponderance for aortoiliac involvement. These findings provide an early characterization of arterial thromboembolic disease in SARS-CoV-2 patients.

Review Meta Analysis
A Meta-Analysis of Locoregional Anesthesia Versus General Anesthesia in Endovascular Repair of Ruptured Abdominal Aortic Aneurysm.
To conduct a meta-analytic review of studies investigating the effect of the anesthesia modality on perioperative mortality in endovascular repair of ruptured abdominal aortic aneurysms (REVAR). ⋯ REVAR under LA is associated with a lower 30-day/in-hospital mortality than REVAR under GA. However, because the included studies may have had some observation bias, further randomized controlled trials are warranted to validate the present results.

Multicenter Study
Outcomes of transcarotid artery revascularization with dynamic flow reversal in patients with contralateral carotid artery occlusion.
The outcomes of carotid revascularization in patients with contralateral carotid artery occlusion (CCO) are controversial. CCO has been defined by the Centers for Medicare and Medicaid Services as a high-risk criterion and is used as an indication for transfemoral carotid artery stenting. With the promising outcomes associated with transcarotid artery revascularization (TCAR), we aimed to study the perioperative outcomes of TCAR in patients with CCO and to assess the feasibility of TCAR in these high-risk patients. ⋯ In this analysis, TCAR seems to be safe in patients with CCO. Caution should be taken in symptomatic patients with CCO and a history of prior stroke as they might have worse outcomes compared with patients with patent contralateral carotid arteries. Studies with larger sample size and longer follow-up are needed to assess the perioperative and long-term outcomes of TCAR in patients with CCO in comparison to other procedures.

Acute limb ischemia (ALI) and cannulation site bleeding are frequent complications of venoarterial (VA) extracorporeal membrane oxygenation (ECMO) and are associated with worse outcomes. The goals of this study were to assess our rates of ECMO-related ALI and bleeding and to evaluate the efficacy of strategies to prevent them, such as distal perfusion cannula (DPC) and ultrasound-guided cannulation. ⋯ ALI and significant bleeding are common occurrences after peripheral VA-ECMO cannulation. Whereas DPC placement did not significantly decrease risk of ALI, ultrasound-guided cannulation decreased the risk of bleeding. Cannulation in the operating room is associated with decreased risk of ALI at the expense of increased risk of bleeding. ALI, older age (≥65 years), and worse heart failure increased risk of in-hospital mortality.
