A new variant of coronavirus (2019-nCoV) causing acute respiratory distress in humans was identified for the first time in 2019, in Wuhan, China. One of the many complications of infection with this coronavirus is hypercoagulopathy, resulting in acute thrombosis; often leading to acute limb ischaemia. Herein, we report 20 cases of COVID-19 with peripheral arterial thrombosis involving either upper or lower limbs. Some patients underwent vascular procedures and most had to undergo amputation at some level. All the cases (n=20) were referred to us during the 8-month period June 2020 to March 2021. The most common age group was between 51 and 60 years, of whom 80% were males; all the patients had diabetes. The right lower limb was most affected (50%); 15 patients underwent embolectomy. Twenty-five per cent of patients presented with wet gangrene. One patient with upper limb thrombosis recovered after embolectomy and did not require any amputation. Eighty-five per cent of patients underwent some form of amputation and the mortality rate was 10%. Arterial thrombosis is one complication patients may develop during COVID-19 illness, which may affect the outcome. Patients with comorbid conditions like diabetes are at higher risk of developing arterial thrombosis during COVID-19 infection. Susceptibility to coagulopathy may continue even after patient discharge and it is important that both patients and treating physicians are aware of this limb-threatening complication and seek early medical attention.
