Early detection of acute pulmonary embolism (PE) in patients with SARS‐CoV‐2 infection is integral to the clinical management of these patients. Many recently published studies have evaluated incidence of PE in hospitalized patients with COVID‐19 1‐9 , however there is relatively limited data describing patients with SARS‐CoV‐2 infection and concomitant diagnosis of acute PE upon initial presentation. Therefore, the purpose of this study is to (i) evaluate the incidence of acute pulmonary embolism (PE) in patients undergoing computed tomography pulmonary angiography (CTPA) in the emergency department (ED) across six hospitals in New York City during the height of the COVID‐19 pandemic compared to a non‐pandemic period, and (ii) compare the characteristics and early outcomes of patients presenting with PE during the pandemic (n=87) to patients presenting with PE during a non‐pandemic period (n=34).

Corticosteroid injection and viscosupplementation have been the most studied, but there is still no consensus about their value. Thermal nerve ablation, including both radiofrequency ablation and cryoneurolysis, is a promising new modality of therapy that may increase in clinical use given current data showing favorable outcomes. Of the future therapies that are currently under investigation, synovial embolization via the geniculate arteries represents an exciting new approach that may soon be available clinically. There are various percutaneous interventions available for the treatment of osteoarthrosis of the knee that address pain and prolong the time to arthroplasty.

BACKGROUND AND PURPOSE:In recent years, the transradial approach has become more widely adopted for neuroendovascular procedures. The purpose of this study was to evaluate the safety and feasibility of a transradial approach and distal transradial access for neuroendovascular procedures in a single center. MATERIALS AND METHODS:Retrospective analysis was performed for all patients who underwent transradial approach or distal transradial access neuroendovascular procedures from January 2016 to August 2019 at a single center. Exclusion criteria included a Barbeau D waveform, a radial artery of ,2 mm on sonographic evaluation, and known radial artery occlusion. Procedures were evaluated for technical success (defined as successful radial artery access and completion of the intended procedure without crossover to an auxiliary access site), complications, and adverse events during follow-up at 30 days. RESULTS:The transradial approach or distal transradial access was attempted in 279 consecutive patients (58.1% women; median age, 57.7 years) who underwent 328 standard or distal transradial approach procedures. Two-hundred seventy-nine transradial approach and 49 distal transradial approach procedures were performed (cerebral angiography [n ¼ 213], intracranial intervention [n ¼ 64], head and neck intervention [n ¼ 30], and stroke intervention [n ¼ 21]). Technical success was 92.1%. Immediate adverse events (2.1%) included radial access site hematoma (n ¼ 5), radial artery occlusion (n ¼ 1), and acute severe radial artery spasm (n ¼ 1). Thirty-day adverse events (0.3%) included a radial artery pseudoaneurysm (n ¼ 1). Twenty-six cases (7.9%) required crossover to transfemoral access. CONCLUSIONS:The transradial approach for neuroendovascular procedures is safe and feasible across a wide range of neuroendovascular interventions.
