The causes can be divided into respiratory and non‐respiratory (Fig.  1 ). A respiratory cause for such presentation is pain referring from lower lungs involved by the SARS‐CoV‐2. The SARS‐CoV2 infection seems to increase the risk of thrombosis 4 ; thus, the non‐respiratory causes can be further classified as thrombotic and non‐thrombotic. Non‐thrombotic causes include pancreatitis, peritonitis, colonic distension, and colitis, while thrombotic etiologies are mesenteric vessel ischemia (occlusive or non‐occlusive), renal vessels infarcts, appendagitis, and omental infarcts (Fig.  1 ).
