Angiography provides important information regarding the perfusion and patency of distal arteries (e.g. femoral artery). The presence of collateral arteries in the pelvic and groin area is important in maintaining crucial blood flow and lower limb viability. However, angiography should only be used if symptoms warrant surgical intervention. [2]
The common iliac artery is a large artery of the abdomen paired on each side. It originates from the aortic bifurcation at the level of the 4th lumbar vertebra.It ends in front of the sacroiliac joint, one on either side, and each bifurcates into the external and internal iliac arteries.
Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta.The procedure is known as an aortogram. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
CO2 Angiogram showing Abdominal Aorta, visceral arteries and iliac arteries. Carbon dioxide angiography is a diagnostic radiographic technique in which a carbon dioxide (CO 2) based contrast medium is used - unlike traditional angiography where the contrast medium normally used is iodine based – to see and study the body vessels.

Contrast angiography is the most readily available and widely used imaging technique. [citation needed] Modern computerized tomography (CT) scanners provide direct imaging of the arterial system. Studies have shown the sensitivity and specificity of CT in identifying lesions with >50% stenosis to be 95% and 96%, respectively. [58]
Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, ...
Ultrasonography of suspected or previously confirmed chronic venous insufficiency of leg veins is a risk-free, non-invasive procedure. It gives information about the anatomy, physiology and pathology of mainly superficial veins.
Fluorescence angiography enables the visualization of regional blood flow using a charge-coupled camera. A 2016 study determined that it “is a valuable tool in visualizing real-time procedural outcomes and providing additionally useful information on regional tissue perfusion.” [ 6 ]
