AngiographyThe term “angiography” is composed of two

part:angeion : vessel(artery, vein etc )graphy : record•Angiography(arteriography)is a medical

technique to diagnose or healing of the arteriosclerosis or other cardiovascular disease

•Two important procedure of angiography is catheter angiography & angioplasty

AngiographyAn angiograhy is also called arteriogram, is

an invasive diagnostic test that uses X-RAYS to take pictures of your blood vessels.

A long flexible catheter is inserted through the blood stream to deliver dye (contrast agent) into the arteries making them visible on the X-RAYS.

This test helps to diagnose the stroke,tumor,clots and arterial stenosis.

AngiographyAngiography was first performed by a

Portuguese physician whose name was “Egas Moniz”

It was done in 1927.

AngiographyAn angiogram uses a radiopaque (radiation

can‟t pass through it) substance, or dye, to make the blood vessels visible under x ray. this substance is named as “contrast media” .

X-ray is not able to move across contrast media so it makes shadow in the image and if the vessel have stenosis (being narrow) , it will be seen.

In angiography , we take a lot of picture per a second ,so we have a data like movie.

Angiographyto look at the left side of the heart and the

arterial system we use the femoral arteryto look at the right side of the heart and the

venous system we use the jugular or femoral vein

in order to diagnose the problem by cardiologist ,The final data will copy on CD

Angiography

AngiographyThere are several type of angiography that

can be performed for different organs and by different technique but here, we discuss about catheter angiography and angioplasty.

For example there are micro angiography, neurovascular angiography and peripheral angiography.

Coronary catheterizationIt is a diagnostic testWe can diagnose cardiac disease through ita physician guides a small tube-like device

called a catheter, typically ~2.0mm in diameter, through the large arteries of the body until the tip is just within the opening of one of the coronary arteries

blood pressures are monitored through the catheter to verify that the catheter does not block blood flow

Catheterdesigned to be radiodense for visibility

through vesselsBy it, we can inject the contrast mediaHas a sensor for monitor the blood pressure

Catheter

Catheter

AngioplastyIt is a therapeutic procedureBy this, we can prevent the heart attach in

result of artheriosclerosisWe insert a stent and a balloon by catheterStent is extended by balloon in the place of

stenosisExtension of stent keep the blood open

How does angioplasty done?

Catheter and balloon

Please don,t be cardiac patient…

Thank you
