Treating Peripheral Arterial Occlusive Disease and Acute Limb Ischemia During a COVID-19 Pandemic in 2020.

ABSTRACT

BACKGROUND: For many surgeons the outbreak of SARS-CoV-2 meant a downscaling of surgical interventions. The aim of this study was to investigate the impact of the measures taken on the care for patients with peripheral arterial disease (PAOD) and acute limb ischemia (ALI). METHODS: A retrospective analysis of the vascular practices of 2 major teaching hospitals in the Netherlands was performed. All interventions and outpatient visits for PAOD or ALI in 2020 were included. Patients treated in 2018 and 2019 were to serve as a control group. Data were analysed using descriptive statistics. RESULTS: In 2020, a total of 1513 procedures were performed for PAOD or ALI. This did not differ significantly from previous years. Overall, Fontaine 2 and 4 were the most frequent indications for intervention. A significant increase in the number of major amputations was observed in 2020 compared to 2018 (P< 0.01). This was mainly due to patients suffering from PAOD Fontaine 4. Inversely, a reduction in the number of femoro-popliteal bypasses was observed between 2020 and 2018. The number of outpatient visit due to Fontaine 2 was significantly lower in 2020 compared to 2018. CONCLUSIONS: The vascular practices of our hospitals were minimally influenced by the measures taken due to the outbreak of SARS-CoV-2. There was an increase in the number of amputation but an enormous surge in patients presenting with critical limb ischemia was not observed.
