Clinical Application: Pulmonary Angiography and Thoracic Aortography

PULMONARY ANGIOGRAPHY

It is the study of the blood

circulation leading from the right

ventricle of the heart to the

lungs to the left atrium of the

heart

Arteriovenous malformation

abnormal connection between arteries and veins

Pulmonary Embolism

Formation of clots

Arterial hypoplasia

underdevelopment of the artery

Pulmonary hypertension

It is a term to describe a rare disease in which the blood pressure in the lungs (pulmonary artery

system) is higher than normal, results when the blood vessel constricts

Contraindications

• Patient who had recent myocardial infarction

• Pulmonary hypertension (arterial pressure above 60mm hg)

• Severe systemic illness

• Allergy to CM

• Percutaneous venous puncture of upper extremity

• Cut-down antecubital approach

• Transjugular approach

• Femoral vein approach

Approaches for PA

low-osmolar, non-ionic

contrast media

Contrast media for PA

• Trunk of pulmonary artery - 50-60 ml

• R or L pulmonary artery - 30-40 ml

• Lobes - 15-20 ml

Amount of Contrast Media employed

closed-end

multiple side holes catheter

The prepared catheter for pulmonary angiography is _______ for pulmonary artery injection however it

is hard to manipulate.

hockey stick catheter

For selective catheterization of segmental branches headhunter and

______ is used.

Straight Tip

Used for non-selective angiography.

Single Curve

Used for selective angiography

Pigtail

Frequently placed on the aortic arch to demonstrate the primary vessels that

arise off the arch.

Coronary Arteriography

• Used to visualized blood vessel supplying the heart which includes the coronary arteries and its branches.

Left Ventriculography

• An examination of the left ventricle of the heart which is an integral part of every coronary arteriographic study.

Right Ventriculography

An examination of the right ventricles of the heart.
