Abstract:
The pathophysiology and predictability of radial artery thromboembolic events in patients with COVID-19 is not fully understood. We report a case of thumb and index finger gangrene and multiple digit amputations secondary to digital artery occlusion after radial artery cannulation in a patient admitted with COVID-19 pneumonia and encephalopathy. The exact association, causality, and potential hand manifestations in this patient population is unclear at this time, but is of particular interest in the current state of the pandemic.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
