Recurrence of Upper Extremity Deep Vein Thrombosis Secondary to COVID-19.

Infection with SARS-CoV-2 leading to COVID-19 induces hyperinflammatory and hypercoagulable states, resulting in arterial and venous thromboembolic events. Deep vein thrombosis (DVT) has been well reported in COVID-19 patients. While most DVTs occur in a lower extremity, involvement of the upper extremity is uncommon.

COVID-19 as a Trigger of Recurrent Guillain-Barré Syndrome.

Coronavirus 2019 (COVID-19) has been reported to trigger Guillain-Barré syndrome (GBS). While uncommon, recurrent GBS (rGBS) episodes, triggered by antecedent viral infections, have been reported in a small proportion of GBS patients, here we describe a patient with a recurrent case of GBS, occurring secondary to COVID-19 infection. Before this patient's episode, he had two prior GBS flares, each precipitated by a viral infection followed by complete recovery besides intermittent paresthesias.
