ABSTRACT

Although coronavirus disease 2019 seems to be the leading topic in research number of outstanding studies have been published in the field of aorta and peripheral vascular diseases likely affecting our clinical practice in the near future. This review article highlights key research on vascular diseases published in 2020. Some studies have shed light in the pathophysiology of aortic aneurysm and dissection suggesting a potential role for kinase inhibitors as new therapeutic options. A first proteogenomic study on fibromuscular dysplasia (FMD) revealed a promising novel disease gene and provided proof-of-concept for a protein/lipid-based FMD blood test. The role of NADPH oxidases in vascular physiology, and particularly endothelial cell differentiation, is highlighted with potential for cell therapy development. Imaging of vulnerable plaque has been an intense field of research. Features of plaque vulnerability on magnetic resonance imaging as an under-recognized cause of stroke are discussed. Major clinical trials on lower extremity peripheral artery disease have shown added benefit of dual antithrombotic (aspirin plus rivaroxaban) treatment.

ABSTRACT

BACKGROUND: A systemic coagulation dysfunction has been associated with COVID-19. In this case report, we describe a COVID-19-positive patient with multisite arterial thrombosis, presenting with acute limb ischaemia and concomitant ST-elevation myocardial infarction and oligo-symptomatic lung disease. CASE SUMMARY: An 83-year-old lady with history of hypertension and chronic kidney disease presented to the Emergency Department with acute-onset left leg pain, pulselessness, and partial loss of motor function. Acute limb ischaemia was diagnosed. At the same time, a routine ECG showed ST-segment elevation, diagnostic for inferior myocardial infarction. On admission, a nasopharyngeal swab was performed to assess the presence of SARS-CoV-2, as per hospital protocol during the current COVID-19 pandemic. A total-body CT angiography was performed to investigate the cause of acute limb ischaemia and to rule out aortic dissection; the examination showed a total occlusion of the left common iliac artery and a non-obstructive thrombosis of a subsegmental pulmonary artery branch in the right basal lobe. Lung CT scan confirmed a typical pattern of interstitial COVID-19 pneumonia. Coronary angiography showed a thrombotic occlusion of the proximal segment of the right coronary artery. Percutaneous coronary intervention was performed, with manual thrombectomy, followed by deployment of two stents. The patient was subsequently transferred to the operating room, where a Fogarty thrombectomy was performed. The patient was then admitted to the COVID area of our hospital. Seven hours later, the swab returned positive for COVID-19. DISCUSSION: COVID-19 can have an atypical presentation with thrombosis at multiple sites.
