How to use

Tap or click any coloured artery

Each artery is coloured by what the radiologist wrote about it. You can also pick any item from the list below. The body outline, bones and kidneys are only there to help you find your way.

All findings, top to bottom

What this means in plain words

The scan followed the body's main artery (the aorta) from the diaphragm down through the belly, and then the arteries of both legs down to the feet. The arteries show widespread hardening and plaque (atherosclerosis).
One widened spot: high up, where the aorta passes through the diaphragm and 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 a focal fusiform (spindle-shaped) aneurysm.
Narrowed places (how much of the channel is blocked by plaque): left kidney artery about 80%, right kidney artery about 50% (both at their start); the aorta below the kidney arteries up to 60% (at the L2–L3 spine level); right common iliac about 75% and left about 70%; the main thigh arteries (superficial femoral) up to 80% in their lower third, in both legs.
Below the knee: in both legs, no X-ray dye (contrast) was seen in the middle and lower parts of the 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. The left posterior tibial has mild narrowing. Flow in the arteries on top of both feet (dorsalis pedis) was weak.
Mild changes only, no significant narrowing: gut arteries (coeliac and mesenteric), where the aorta splits, external and internal iliacs, groin (common femoral) arteries, the arteries behind the knee (up to 20%), tibioperoneal trunks and peroneal arteries. The deep thigh arteries (profunda femoris) were normal.
Other notes: a few tiny liver cysts and wear-and-tear (degenerative) changes of the spine. The report ends with “Recommend clinical correlation”, which means the doctors need to 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

These are 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? When should it be scanned again, and what size or change would worry you?
Do the kidney artery narrowings (left about 80%, right about 50%) affect his kidney function or blood pressure? Are blood or urine tests needed?
Do the narrowings in the aorta, iliac and thigh arteries need treatment, or will medicines and regular checks do?
With no contrast seen in parts of the shin arteries, how well is blood reaching his feet? Would other tests help, such as an ankle-brachial index (ABI) or a Doppler ultrasound?
Which medicines, activity and foot-care routines do you recommend, and what should we check for every day?
Exactly which symptoms should make us come to hospital straight away?
Do the liver cysts or the spine changes need any follow-up?

Seek 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. Also see a doctor urgently for a 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. The shape of the body, the vessel paths, sizes and the lengths of the coloured segments are approximate and only for orientation. “Absent flow” / “no contrast seen” describes what the scan showed in that segment. It is not proof that no blood reaches that area. This page is not a diagnosis and not treatment advice. Please discuss the findings with his treating doctors.
