The catheter has to be inserted through the right femoral artery, because in about two-thirds of cases the aortic dissection spreads into the left common iliac artery. The aortogram was previously considered the gold standard test for the diagnosis of aortic dissection, [ 1 ] with a sensitivity of up to 80% and a specificity of about 94%. [ 2 ]

Cerebral angiography is a form of angiography which provides images of blood vessels in and around the brain, ... Right common femoral artery (RFA) is the preferred ...
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
The procedure involves gaining percutaneous transarterial access by the Seldinger technique to the hepatic artery with an arterial sheath, usually by puncturing the common femoral artery in the right groin and passing a catheter guided by a wire through the abdominal aorta, through the celiac trunk and common hepatic artery, and finally into ...
Depending on the type of angiogram, access to the blood vessels is gained most commonly through the femoral artery, to look at the left side of the heart and at the arterial system; or the jugular or femoral vein, to look at the right side of the heart and at the venous system.
As more embolizing agent is administered, blood flow will slow down significantly. Over time, the decreased blood flow causes the fibroid to shrink. Both the left and right uterine arteries are embolized since unilateral UAEs have a high risk of failure. [28] The procedure can be performed in a hospital or surgical center.
