implantation of patient
1.
(A ) At day 6, X-ray radiography showed a blurred texture of
bilateral lungs. (B ) At day 10, representative COVID-19 lesions
could be seen in bilateral lungs. (C-D ) IVC filter implantation
was successfully performed with the aid of DSA guiding. The IVC was
patent. (E ) At day 13, there were fewer inflammatory lesions
compared to day 6 (A ). (F ) At day 23, the follow-up CT
scan showed fewer inflammatory lesions compared to the day 10 CT image
(B ).
Figure 2. Bedside ultrasound-guided IVC filter implantation
of patient 2 on the isolation
ward.
(A-B ) Severe ischemia signs were observed in the right thigh
and left toes. (C ) There was no blood flow in the right iliac
artery and vein. (D ) The tip of the IVC filter sheath was
adjusted to be 1 cm below the right renal vein. (E ) One
retrievable inferior vena cava filter was implanted. (F ) At day
3, after emergent right thigh amputation surgery, X-ray radiography
showed obvious inflammatory lesions in bilateral lungs. There was no
shift of the inserted IVC filter. (G ) At day 9, in the
intensive care unit, bedside X-ray radiography presented exacerbation in
bilateral lungs. Black arrow indicates the inferior vena cava filter.
Figure 3. Radiographic information and bedside IVC filter
implantation of patient
3.
(A-B ) At day 3, a CT scan showed representative COVID-19
lesions in transverse and coronal windows, respectively. (C-D )
X-ray radiography presented the compressed fractures in the 12th
thoracic vertebrae (T12) and the 1st lumbar (L1) vertebrae. (E )
There was no blood flow in the left iliac vein. (F-G ) After
adjusting the tip of the IVC filter sheath, one retrievable inferior
vena cava filter was implanted 1 cm below the right renal vein.
(H-I ) At day 9, X-ray radiography showed successful internal
fixation surgery. There was no shift of the inserted IVC filter.
(J-K ) At day 18, there were obviously fewer inflammatory
lesions in transverse and coronal windows compared to day 4
(C-D ), respectively. Black arrow indicates the inferior vena
cava filter.
