Sudden development of the upper and lower limb ischemia as the first manifestation of COVID-19 infection

INTRODUCTION AND IMPORTANCE: Atherosclerosis is the most common cause of peripheral vascular disease, and common predisposing causes are inflammation and diabetes. It is over two year that the COVID-19 pandemic has impacted the world and costed millions of lives. CASE PRESENTATION: The patient was a case of COVID-19 infection presenting as acute arterial occlusion in the upper and lower limb. CLINICAL DISCUSSION: Hyper coagulopathy is one of the COVID-19 outcomes that may develop PAD following the involvement of vascular endothelium in the cytokine storm phase. Endothelial damage following COVID-19, especially in those with underlying diseases such as diabetes mellitus or inflammatory diseases with vascular involvement, can cause acute vascular events. CONCLUSION: Patients with inflammatory diseases and diabetes are prone to the uncommon symptoms of COVID-19 and more vulnerable to peripheral vascular occlusion, especially when the underlying disease remains uncontrolled, so anticoagulation with therapeutic doses is recommended for their treatment. Inflammation as a predisposing factor for PAD should be controlled using plasmapheresis or anti-inflammatory drugs depending on the patient's condition.
