Critical: 70–80% narrowed Critical: no flow seen Significant: 50–60% / weak flow Aneurysm Mild / normal

What this means in plain words

The scan followed the body's main artery (the aorta) from the diaphragm down through the belly, and the arteries of both legs down to the feet. There is widespread hardening and plaque (atherosclerosis).
One widened spot: where the aorta passes through the diaphragm, above the kidney arteries, a short piece (over about 2 cm long) is widened to 2.8 cm front-to-back. The report calls this an aneurysm.
Narrowed places: left kidney artery about 80% and right about 50% (at their start); the aorta below the kidney arteries up to 60% (level of the L2–L3 spine disc); right common iliac about 75% and left about 70%; both main thigh arteries up to 80% in their lower third.
Below the knee: in both legs no dye was seen in the middle and lower anterior tibial artery, and its upper part had significantly weak flow. In the right leg the same was seen in the middle and lower posterior tibial artery, with weak flow in its upper part. Flow on top of both feet was weak.
Mild changes only: gut arteries, where the aorta splits, external and internal iliacs, groin arteries, behind the knees (up to 20%), tibioperoneal trunks, peroneals and the left posterior tibial. The deep thigh arteries were normal.
Also noted: a few tiny liver cysts, and wear-and-tear changes of the spine. The report ends “Recommend clinical correlation”, which means the doctors will combine these images with his symptoms, an examination and other tests. This page does not say what treatment, if any, is needed.

Questions you could ask the vascular surgeon

Ideas to help the conversation. They are not medical advice.

Which of these findings matter most for his symptoms right now?
How should the 2.8 cm aneurysm near the diaphragm be followed up, and when should it be scanned again?
Do the kidney artery narrowings affect his kidney function or blood pressure? Are tests needed?
Do the narrowings in the aorta, iliac and thigh arteries need treatment, or will medicines and regular checks do?
With no dye seen in parts of the shin arteries, how well is blood reaching his feet? Would an ankle-brachial index (ABI) or Doppler ultrasound help?
What medicines, activity and daily foot care do you recommend?
Exactly which symptoms should make us come to hospital straight away?
Do the liver cysts or spine changes need any follow-up?

Get emergency care immediately for sudden severe pain in the belly, back or chest, fainting or collapse, or if a leg or foot suddenly becomes very painful, cold, pale or blue, numb or weak. See a doctor urgently for any foot wound, sore or dark patch that is new or not healing.

Please read: this is an illustration drawn from the written radiology report. It is not a 3D reconstruction or segmentation of his actual CT images. Body shape, vessel paths, vessel thickness and the length of each coloured part are approximate, and vessels are drawn thicker than life so they can be seen. “No flow seen” / “absent opacification” describes what the scan showed in that segment. It is not proof that no blood reaches that area. This page is not a diagnosis or treatment advice. Please discuss everything with his treating doctors.
