Introduction
Since December 8, 2019, an epidemic of coronavirus disease 2019
(COVID-19) has spread rapidly. There are more than 3,672,238 COVID-19
patients worldwide, with 254,045 deaths having been reported to
date1. Deep venous thrombosis (DVT) has been reported
to be as high as 31% in intensive care unit (ICU) patients with
COVID-19 infections2. Moreover, fatal pulmonary
embolization (PE) has been reported to be as high as 20.6% in severe
ICU COVID-19 patients3. Inferior vena cava filter
(IVCF) implantation is the recommended precautionary strategy for fatal
PE among DVT patients 4. IVCF implantation is
generally performed under X-ray or color ultrasound (US) guidance4. Ultrasound-guided IVCF implantation at the bedside
is however more convenient and carries a lower risk of infection5. There is currently no guidance with respect to the
preferred method of implantation during the current COVID-19 pandemic.
Here, we present three confirmed cases of DVT-COVID-19 patients. All of
them had reached IVCF implantation intervention indications. We
performed IVCF implantation for the first patient under digital
subtraction angiography (DSA) in the DSA operating room and for the
other two, under bedside ultrasound in the COVID-19 isolation ward. All
patients or their representatives have consented to the publication of
details and images pertaining to the cases.
