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).

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.

Objectives Novel coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) virus has been declared a pandemic by the World Health Organization as of March 11, 2020. Pregnant women naturally have a reduced immune system due to immunological changes and decreased lung capacity due to respiratory adaptations, making them more susceptible to coronavirus complications. Within the Mount Sinai Health system, more than 15,000 deliveries are performed annually. We began to care for pregnant women with known COVID-19 infections in late March of 2020. In early April 2020, a policy was implemented to perform universal COVID-19 testing for all women planning to deliver within the Mount Sinai Health system. We examined the antibody response of postpartum women who delivered at Mount Sinai Hospital with a SARS-CoV-2 infection between the study intervals during March 15, 2020, through April 30, 2020. Study Design This was a prospective observational study examining the immune response of pregnant women who delivered at Mount Sinai Hospital with a polymerase chain reaction (PCR)-confirmed SARS-CoV-2 infection. Women with a SARS-CoV-2 infection were contacted via phone to discuss participation in the study. Patients who consented were scheduled for a phlebotomy visit to assess their antibody titer levels to COVID-19. The COVID-19 enzyme-linked immunosorbent assay (ELISA) immunoglobulin (Ig)-G antibody test was used to evaluate the patients' antibody titers. The assay detects IgG antibodies for the detection of IgG seroconversion in patients following a known recent SARS-CoV-2 infection. Results A total of 120 patients were identified with a documented SARS-CoV-2 infection who delivered within the prespecified time frame. Of those patients, 25 women agreed to participate and were included. Of them, 64.00% were Caucasian with a mean age of 35 years. The mean body mass index (BMI) was 30 kg/m2 and the majority of patients had commercial insurance (88.00%). The majority of women were asymptomatic for COVID-19 at the time of admission (80.00%) and the average gestational age of delivery and diagnosis of COVID-19 was 39 weeks' gestation. The later the gestational age at the time of diagnosis, the lower the antibody titer response. When examining the interval from diagnosis to antibody titer analysis, patients with the highest titers (2,880) tended to have a shorter interval between their COVID-19 diagnosis and the time at which the titer level was drawn. Patients with symptoms on admission had similar antibody titer levels when compared with women who were asymptomatic. Conclusion The antibody response among women infected with COVID-19 during pregnancy appears to be greater when the patients are diagnosed at an earlier gestational age. Key Points

Objective This study aimed to investigate pregnancy rate, pregnancy outcomes, and resumption of menses after transcatheter arterial embolization (TAE) for obstetric hemorrhage (OH). Study Design Sixty-seven patients who underwent TAE for OH from 2006 to 2020 within an urban, multihospital health care system were identified retrospectively. Selected patients were interviewed by phone to complete a survey with a primary outcome of self-reported pregnancy in those seeking pregnancy. Secondary outcomes included pregnancy outcomes and resumption of menses. Univariate testing of association of pregnancy and miscarriage rate with embolic agent was performed using Fisher's exact test. Results Thirty-three of 50 patients (66%) meeting the inclusion criteria completed the survey on fertility, a median of 47 (range, 13–123) months after TAE for OH. Of the 13 patients who attempted pregnancy, there was a pregnancy rate of 77% and miscarriage rate of 38%. Those who delivered live newborns conceived spontaneously, carried to term, and delivered a healthy newborn via cesarean section at a weight appropriate for gestational age. Thirty (91%) patients resumed menstruation, and the majority with unchanged frequency. Most patients underwent bilateral uterine artery embolization with radial artery access (54%). The most common embolic agents used were gelfoam only (30%) and glue only (24%). There was no statistically significant association between embolic agent and pregnancy or miscarriage rate. Conclusion Spontaneous pregnancy with live birth and resumption of menses can occur in a majority of patients after TAE for OH. Key Points
