Peripheral (Leg Artery) Angiography

Peripheral angiography maps the arteries that supply the legs, from the aorta in the abdomen down to the feet. It can be done non-invasively with CT or MR angiography, or by catheter, with dye injected directly into the artery while X-ray images are taken (digital subtraction angiography).

It shows exactly where arteries are narrowed or blocked in peripheral arterial disease, and the catheter version lets the specialist treat a lesion with a balloon or stent in the same session. It is a planning test for intervention; a diagnosis of leg artery disease is normally made earlier with simple pressure measurements and ultrasound.

What Peripheral (Leg Artery) Angiography shows

The images display the iliac arteries in the pelvis, the femoral and popliteal arteries in the thigh and behind the knee, and the three tibial arteries in the calf. For each segment the report describes the degree and length of narrowing, complete occlusions, calcification, aneurysms and the collateral vessels that bypass blockages. Crucially, it shows whether there is a good artery below the blockage for a balloon, stent or surgical bypass to connect to, and which vessels feed a non-healing foot wound.

When Peripheral (Leg Artery) Angiography is recommended

• People with calf, thigh or buttock pain on walking that limits life despite exercise therapy and medicines
• People with rest pain in the foot, ulcers or gangrene, where restoring blood flow is urgent
• Diabetic patients with foot wounds that are not healing
• Before planned angioplasty, stenting or bypass surgery of the leg arteries
• Follow-up of a failing bypass graft or stent
• Assessment of popliteal or iliac aneurysms

Limits and situations where another test is better:

• A suddenly cold, pale, painful or numb leg is an emergency that needs a vascular team locally within hours
• Mild claudication is first treated with supervised walking, stopping smoking and medicines, without any angiogram
• Leg swelling and varicose veins are vein problems and are assessed by venous duplex ultrasound instead
• Severe kidney impairment calls for duplex ultrasound, carbon dioxide angiography or non-contrast MR as alternatives
• Heavy calcium in diabetic calf arteries can limit CT accuracy

How to prepare

• A kidney function blood test within the past few weeks
• Fasting for 4 to 6 hours before catheter angiography
• Instructions on metformin and blood thinners from the team
• Good hydration the day before and after
• Bring ankle-brachial index results, duplex reports and photos of any wounds
• Tell staff about contrast allergy

What happens during the test

CT angiography takes 10 to 15 minutes with contrast through an arm vein. Catheter angiography takes 30 to 60 minutes, longer with treatment. Local anaesthetic is injected at the groin, or sometimes the arm or foot, and a catheter is placed in the artery. Each dye injection gives a warm feeling down the leg and you need to keep very still. If a balloon is inflated you may feel a brief ache. The puncture is sealed with pressure or a closure device and you rest flat for 4 to 6 hours.

Results and next steps

Catheter findings are explained immediately, and CT or MR reports follow within about 24 hours. A vascular surgeon or interventional specialist then advises on medicines alone, angioplasty with or without stent, atherectomy, or bypass surgery. For limb-threatening ischaemia, treatment should follow within days. Everyone with leg artery disease needs antiplatelet therapy, a statin and risk factor control, since heart attack and stroke risk is raised.

• Test time: 15 to 60 minutes
• Results ready: Same day to 24 hours
• Back to everyday activity: 1 to 2 days after catheter test

Safety and risks

• Bruising, bleeding or a false aneurysm at the puncture site
• Kidney injury from contrast, especially with diabetes or existing kidney disease
• Allergic reaction to contrast
• Artery dissection, clot or debris travelling downstream, which may need immediate treatment
• Radiation exposure

Arranging Peripheral (Leg Artery) Angiography in Türkiye

For stable claudication, a visit of 4 to 6 days can cover assessment, angiography and an endovascular procedure if suitable. Foot ulcers and critical ischaemia are different: long flights, repeated dressings and the possibility of staged surgery make local care safer. A remote review of your duplex or CT report beforehand helps set honest expectations.
