Angiography: preparation and aftercare
Angiography images blood vessels; balloons and stents are separate treatments. Confirm preparation and discharge instructions with your procedure team.
Distinguish imaging from treatment
Angiography examines blood vessels using contrast. Catheter angiography differs from CT or MR angiography. Finding a narrowing does not automatically mean a stent is needed; in some people a separately agreed treatment can take place in the same session.
Preparation checklist
- Report medicines, previous contrast reactions, kidney disease and possible pregnancy.
- Get written fasting and medicine instructions; do not stop blood thinners or diabetes medicines yourself.
- Ask about transport home, support and discussing results.
What to expect on the day
Catheter angiography commonly uses access at the wrist or groin with local anaesthetic. Your team explains the method, expected benefit and alternatives. Preparation and observation affect the total time; discharge timing is not identical for everyone.
Risks and returning home
Bruising or tenderness may occur. Bleeding, contrast reactions, kidney effects and rare serious vascular problems are assessed individually. Follow discharge advice for the access site, activity and fluids, respecting any heart- or kidney-related fluid restriction.
Which symptoms must not wait?
Seek prompt help for increasing swelling, persistent bleeding, severe pain or a cold, pale treated limb. Call 112 for chest pain, severe breathlessness, fainting or sudden speech difficulty or weakness; do not drive yourself.
