1. Thoracic and
coronary
angiography

Dr.Tayseer jamal Aldeen1

2. Common types include:
 coronary angiography – to check the heart and
nearby blood vessels
 cerebral angiography – to check the blood vessels in
and around the brain
 pulmonary angiography – to check the blood vessels
supplying the lungs
 renal angiography – to check the blood vessels
supplying the kidneys

insertion :-
 Radial artery
 Femoral artery

4. Thoracic aortography
 is an angiographic study of the aorta, the
arch, the descending portion of the thoracic
aorta and major branches….

5.  The thoracic aorta extends from the aortic bulb to
the diaphragm and is generally divided into three
main sections: ascending aorta, arch, and descending
aorta. The classic pattern of branching consists of a
right brachiocephalic, left common carotid, and left
subclavian artery

6. Clinical Indications
 Clinical indications for
thoracic angiography include
the following:
• Aneurysms
• Vessel stenosis
• Embolus
• Trauma
• Congenital abnormalities

7.  Catheterization
 The preferred puncture site for a thoracic
aortogram is the femoral artery.
 Contrast Media
 The amount of contrast media for thoracic
angiography is 30 to 50 mL

9. An aneurysm is an abnormal bulge or ballooning in the wall
of a blood vessel. "A proportion of these patients will go on
to have a rupture

11. Arch aortogram clarifies the saccular arch aneurysm arising distal
to the origin of the left subclavian artery in addition to the fusiform
aneurysmal dilatation of the lower descending aorta

12. coronary arteriography
 is a procedure that uses X-ray imaging to see
heart's blood vessels.

13. coronary arteriography
 indications
 Coronary artery
disease
(atherosclerosis)
 Myocardial infarction
1/16/2021

14.  There are three arteries that run over the surface
of the heart
 There is one artery on the right side and two
arteries on the left side of the heart. The one on
the right is known as the right coronary. On the
left side, which is the main side, we have the left
anterior descending (LAD) and then the left
circumflex that supplies the side wall.
 When (LAD) is totally blocked or has a critical
blockage, at the beginning of the vessel, it is
known as the Widow Maker.

19. Catheterization
 the femoral artery is the preferred
site for catheterization .
 both right and left coronary arteries
are routinely examined. Specially
shaped catheters are designed to fit
each of the coronary arteries.

22. Contrast Media
 Approximately 30 to 40 mL of a nonionic, low-
osmolar, water soluble iodinated contrast
media is injected.
 The coronary arteries typically require 7 to 10
mL of contrast media per injection.

23. Imaging
 The imaging rate for angiocardiography is
very rapid, in the range of 15 to 30 frames per
second,
1/16/2021
Dr.Tayseer jamal Aldeen
23

24.  A series of oblique images is obtained to
visualize the coronary arteries .
 Routinely, six views of the left coronary
artery and two views of the right coronary
artery are obtained.

26. Balloon angioplasty
A procedure used to widen
narrowed arteries . typically
to treat arterial
atherosclerosis.
 A deflated balloon
attached to a catheter (a
balloon catheter) is
passed over a guide-wire
into the narrowed vessel
and then inflated to a
fixed size.
1/16/2021
Dr.Tayseer jamal Aldeen
26

27.  The balloon forces expansion of
the blood vessel and the
surrounding muscular wall,
allowing an improved blood
flow.
 A stent may be inserted at the
time of ballooning to ensure the
vessel remains open, and the
balloon is then deflated and
withdrawn.
1/16/2021
Dr.Tayseer jamal Aldeen
27

28.  Stent placement
 To assist in maintaining
patency of the vessel.

32. Risks and Complications
 Risks of angioplasty include
1. vessel rupture
2. vessel perforation,
3. vessel occlusion,
4. embolus formation
5. stent thrombosis,
