Vascular Surgery

Arteries and veins outside the heart: aneurysms repaired from within by stent graft or from without by sew, carotid disease and the strokes it threatens, and the ischaemic limb, where the six Ps and the clock decide everything.

Read the scan

Imaging

See the study, interpret it, then answer the surgical question.

The studies that shape surgical decision-making. Not a radiology curriculum: what the scan changes about the plan, then practice reading it.

Practice the image

Measure what matters

A 74-year-old smoker, screening ultrasound abnormal, now a CT of the abdomen. (Fictional educational case.)

Synthetic educational image · schematic axial CT for aneurysm practice

Find the aneurysmal aorta, understand the mural thrombus, and connect the diameter to the repair decision: the surveillance-versus-EVAR arithmetic practised on one slice.

What each study decides

Investigations

  • ABPI & toe pressures

    • The ankle-brachial index puts a number on perfusion: under 0.9 is disease, under 0.5 is severe, and rest pain usually lives below 0.4.
    • Calcified diabetic vessels resist compression and flatter the ABPI: toe pressures tell the truth the ankle cannot.

  • Duplex ultrasound

    • The specialty's stethoscope: grades carotid stenoses, surveys aneurysms, maps vein for conduit and interrogates grafts and fistulas.
    • Velocities are the language: flow accelerates through a narrowing, and the numbers grade the squeeze.

  • CT angiography

    • The operative map: aneurysm neck and access for EVAR, the level and length of occlusions, and the rupture question answered in one pass.
    • Read it as plumbing: where does contrast enter, where does it stop, what refills beyond, and what would carry a bypass.
