What is difference between angiography and venography?

One of the most common reasons for Angiograms is to see if there is a blockage or narrowing in a blood vessel that may interfere with the normal flow of blood through the body. Venography uses an injection of contrast material to show how blood flows through the veins.

How safe is a venogram?

What are some of the possible risks? There is a very slight risk of an allergic reaction if contrast material is injected. In rare cases, a venogram can cause a deep vein thrombosis (blood clot). There is a risk of injury to the kidneys with contrast injection.

What is venography used for?

A venogram is used to confirm a diagnosis of DVT. It is also used to tell if a vein problem is a blood clot or another kind of blockage. It can be used to look at vein problems present at birth (congenital) or to find a vein for bypass graft surgery. It may be used to find out what is causing swelling or pain in a leg.

What is difference between angiogram and arteriogram?

An angiogram, also known as an arteriogram, is an X-ray of the arteries and veins, used to detect blockage or narrowing of the vessels. This procedure involves inserting a thin, flexible tube into an artery in the leg and injecting a contrast dye. The contrast dye makes the arteries and veins visible on the X-ray.

What do you need to know about angiography and venography?

overview Angiography and Venography are specialized X-ray exams of the arteries and veins to diagnose blockages and other blood vessel problems. One of the most common reasons for Angiograms is to see if there is a blockage or narrowing in a blood vessel that may interfere with the normal flow of blood through the body.

What do you need to know about a venogram?

A venogram is used to diagnose deep vein thrombosis (DVT) or other abnormalities of your veins. This test can also help your healthcare provider diagnose other health problems. A venogram can be done in several ways: Ascending venography.

When to use CT venography for deep intracranial veins?

CT venography (CTV) of the dural venous sinuses and deep intracranial veins is typically indicated for patients who cannot undergo MR venography (MRV) or as a problem-solving tool in complex cases as an alternative to catheter angiography.

Can you have a venogram if you are allergic to contrast?

A bleeding disorder or are taking blood-thinning medicine (anticoagulant), aspirin, or other medicines that affect blood clotting. You may not be able to have a venogram if you are allergic to the contrast dye, or have severe congestive heart failure or severe pulmonary hypertension.
