References

Chest CTA

Pulmonary embolism

3% relevant findings

 

[210,211,212,213,214,215,216]

Follow-up abdominal aorta CTA

Post EVAR

3.6% relevant findings

Reduce the number of follow-ups in patients with normal CTA with no endoleak 1 month after EVAR

[222, 223]

Use doppler US as surveillance unless patient has symptoms or abnormalities on first follow-up

[224]

Spine CTA

Blunt vertebral artery injuries

No relevant findings

 

[225]

Lower extremity CTA

Lower extremity vascular injuries

40% relevant findings

Use CTA only in patients with high clinical suspicion and absence of hard signs

[226]

Routine Compression US

Deep venous thrombosis in patients with Lower Extremity Cellulitis

8% relevant findings

 

[217]

Routine lower extremity veins US

Asymptomatic leg in patients with deep venous thrombosis

0–0.8% relevant findings

 

[218]

Deep venous thrombosis

No relevant findings

Use a D-dimer test together with a Wells score risk factors as screening

[219]

Post-op lower extremity veins US

Deep venous thrombosis

No relevant findings

US pre-op only

[220]

Four extremity vein duplex US

Deep venous thrombosis
