IYSC07 - Arterial Thromboemboli in Hospitalized COVID-19 Patients: A Multi-center Experience

Saturday, June 18, 2022
7:06 AM – 7:12 AM EDT
Objectives: We assessed the incidence of arterial thromboembolic events in in hospitalized patients with coronavirus disease 2019 (COVID-19).

Methods: We performed a retrospective review of 9,460 prospectively collected data from hospitalized COVID-19 patients from March 11, 2020 to December 20, 2021. The primary end point was the incidence of arterial thromboembolic events. The secondary outcomes included death, neurovascular events and amputations in this carefully assessed case series.

Results: A total of 9460 hospitalized COVID-19 patients were reported in the study period. There were 27 (0.3%) with an arterial thromboembolic event. There were 14 (0.15%) with thromboembolic events in the aorta including 8 (0.09%) in the abdominal aorta, 5 (0.05%) in the aortic arch and 1(0.01%) in the descending aorta. There were 12 (0.1%) patients with thromboembolic events in the distal limbs, 11 (0.1%) patients with thromboembolic events in the neurovascular tree and 2 (0.02%) patients with thromboembolic events within the heart (Figure 1). The mortality rate was 30%, stroke rate was 40% and amputation rate was 4%.

Conclusions: Although arterial thromboembolic events are much lower than the rate of venous thromboembolic events, the arterial thromboembolic event risk is not insignificant in the COVID-19 hospitalized patient population. Therefore, careful clinical vascular assessment of all COVID-19 patients is strictly necessary.
