Aorta, Peripheral Arteries and Venous Disease
Assess acute and chronic arterial and venous disease using ultrasound, CT, MRI and angiographic techniques.
How to prepare for the current Final FRCR Part A
Build general-radiology breadth, then practise integrating clinical context, anatomy, multimodality findings, technique and management to select the single best answer.
Core concepts
Concept 1
Define vessel, segment, lumen, wall, collateral circulation, end-organ effect and acuity for aneurysm, dissection, occlusion, stenosis and thrombosis.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Tailor Doppler, CT angiography, MR angiography, venography or catheter angiography to urgency, renal function and intervention planning.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Identify rupture, malperfusion, threatened limb, phlegmasia and other vascular findings requiring immediate specialist action.
Exam cue: Select the examination or intervention that changes management while accounting for contrast, radiation, access and urgency.
Concept 4
Apply normal and variant anatomy, modality technique, image quality and relevant imaging science to aorta, peripheral arteries and venous disease.
Risk pitfalls and guardrails
Reporting diameter or stenosis alone without technique, measurement plane, branch involvement, distal run-off and complication.
Guardrail: Do not anchor on one remembered sign; verify age, localisation, distribution, technique, alternatives and management consequence.
Do not choose a merely plausible SBA option before comparing every option with the full clinical and imaging context.
Guardrail: Re-read the command word and compare every option; the task is to select the best available answer, not the first plausible one.
Memory anchors
Acute aortic syndrome core
Look for dissection, intramural haematoma and penetrating atherosclerotic ulcer plus rupture and malperfusion.
Doppler stenosis assessment
Combine velocity change, waveform alteration, turbulence and downstream effect rather than relying on colour alone.
Threatened limb imaging priority
Do not delay revascularisation for elaborate imaging when clinical findings demand immediate vascular action.
Venous thrombosis extension
State proximal extent, occlusiveness, chronicity clues and complications that alter treatment.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A haemodynamically stable patient has tearing chest pain. CT shows an intimal flap involving the ascending aorta. What is the most appropriate management implication?
CT shows a focal contrast-filled outpouching extending beyond the aortic intima into a thick atherosclerotic wall. What is the most likely diagnosis?
