Severe ischemic complications in Covid-19-A case series.

ABSTRACT

INTRODUCTION: Covid-19 has the propensity to result in a wide array of manifestations. Recently, thromboembolic complications of Covid-19 have been denoted in literature. We report 5 cases of Covid-19 positive patients with no significant comorbidities who developed 1st time episodes of either; acute limb ischemia or bowel ischemia. MATERIAL AND METHODS: This is a retrospective observational study analyzing the clinical characteristics and outcomes of five Covid-19 positive patients. Five patients aged 38-60 presented to our institution from 1st April to 1st June and were diagnosed with Covid-19 pneumonia, subsequently developing severe vascular complications. None of our patients included had any history of thromboembolism nor risk factors that could justify the presentations. PRESENTATION OF CASES Patient 1; presented with bowel ischemia as a first presentation. Patient 2 and 3 developed unsalvageable lower limb ischemia secondary to partial to complete occlusion of infra-renal aorta. Patient 4 presented with acute upper limb ischemia due to complete occlusion of the axillary and brachial artery. Patient 5 developed bilateral lower limb unsalvageable ischemia secondary to aortic bifurcation occlusion. All patients tested Covid-19 positive upon admission, and received standard care. DISCUSSION AND CONCLUSION: The thromboembolic complications seen in our cases were devastating and resulted in significant mortality and morbidity. All vessels affected were medium-large vessels. None of our cases had any significant predisposing medical conditions or history of thromboembolic or ischemic events. A high index of suspicion is necessary when evaluating such patients regardless of thromboembolic history. Appropriate anticoagulation regimens are essential. Our cases add to the currently increasing severe thromboembolic complications of Covid-19.
