Background: Disruptions caused by COVID-19 pandemic have profoundly influenced the management of many conditions, especially vascular pathologies including limb preservation care. The aim of this study is to evaluate the impact of the pandemic on patients with peripheral arterial disease (PAD) focusing on lower limb revascularisation procedure volume, their indication and urgency of surgery. Methods: The Australian Vascular Audit (AVA) was used to capture data on revascularisation procedures before and after the onset of the pandemic in Victoria, Australia. Information on patient demographics, procedures performed, their indication and urgency of surgery were collected. Results: There was a significant 22.7% increase in revascularisations for PAD during the COVID-19 pandemic, driven solely by a 31.9% increase in endovascular revascularisation procedures. Endovascular procedures for all indications of PAD, namely claudication, rest pain and tissue loss, increased by 22.3%, 62.9% and 35% respectively, during the pandemic compared to pre-pandemic times. Open procedures declined by 10.2% during the pandemic. There were significant 13.9% and 62.2% increases in elective and semi-urgent revascularisations respectively during the pandemic while emergency revascularisations for PAD fell by 4.2%. Conclusions: This study found that the volume of revascularisation for PAD increased significantly during the pandemic indicating that patients with PAD had significant deterioration of their condition during the pandemic. This is likely multifactorial; due to disruptions to standard provision of podiatry, vascular surgery and endocrinology services to these patients, a decline in overall health and changes in health-related behaviours due to restrictions and infection control methods imposed during the pandemic. The number of elective and semi-urgent procedures also increased during the pandemic which reflects the significant deterioration of PAD patients during the pandemic. This study highlights a concerning trend of worsening PAD when routine care of these patients is disrupted. Such data should be instrumental in contingency planning and resource allocation for managing the ongoing pandemic.

Revascularisation procedures for all indications of PAD, namely claudication, rest pain and tissue loss, increased by 14.8%, 39.2% and 27.4% respectively, during the pandemic compared to pre-pandemic times. Open procedures declined by 10.2% during the pandemic. There were significant 13.9% and 62.2% increases in elective and semi-urgent revascularisations respectively during the pandemic while emergency revascularisations for PAD fell by 4.2%. There were no significant increases in toe, forefoot or below knee amputations during the pandemic compared to pre-pandemic times. Conclusions This study found that the volume of revascularisation for PAD increased significantly during the pandemic indicating that patients with PAD had significant deterioration of their condition during the pandemic.
