Objective:

To determine the clinical-surgical features of critical limb ischaemia (CLI) within the context of infection by SARS-CoV-2.

Methods:

Cross-sectional, retrospective, observational, descriptive study, with clinical data obtained from printed and electronic records of patients with CLI treated by the Angiology and Vascular Surgery Service of the General Hospital of Mexico in the period between January 2020 and July 2021.

Results:

We evaluated the data of 33 patients with critical limb ischaemia of which 15 were positive for SARS-CoV-2 in the period from January 2020 to July 2021, females were the most affected representing the 53.3% of the total, patients under 60 years old accounted for 26.67%. Twenty-six percent of the patients presented critical limb ischaemia without having previous comorbidities, 60% of these presented with an advanced state of the disease and a delay in specialised medical care of more than 6 hours after the onset of symptoms, which warranted a major amputation in 37% of cases, the lower extremities represented 90% of the affected anatomical regions.

Conclusions:

the outcomes in our study show that the incidence of critical limb ischaemia during the SARS-CoV2 pandemic period occurred in an atypical way in a segment of young patients and without known event-generating comorbidities. Thromboembolic events, probably associated with the hypercoagulable state generated by this infection, also evolved rapidly and aggressively from the onset of symptoms despite prompt treatment.
