Angiography is a relatively safe procedure. But it does have some minor and very few major complications. After an angiogram, a sudden shock can cause a little pain at the surgery area, but heart attacks and strokes usually do not occur, as they may in bypass surgery.
Some bruising is common, but occasionally a hematoma may form. This may delay hospital discharge as flow from the artery into the hematoma may continue (pseudoaneurysm) which requires surgical repair. Infection at the skin puncture site is rare and dissection (tearing) in the interior wall of an arterial blood vessel is uncommon.
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 .

The possibility of tape removal causing trauma is also significantly increased in older people, people with sensitive skin, dermatitis, dehydration or side effects of medications. [ 14 ] As noted above, there have been several studies looking at the efficacy and safety of eye ointments/lubricants as adjuncts with tape or as a stand-alone ...
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
The most common angiographic techniques were fluorescein (FA) or indocyanine green angiography (ICGA), which both involve the use of an injectable dye. Intravenous dye injection is time-consuming and can have adverse side effects.
An imaging dye is loaded into the blood vessel through the catheter and the movement of the dye in the blood vessel is recorded as an angiogram. [18] Doctors could determine if there are any abnormalities in the blood vessel using fluoroscopy , computed tomography (CT) angiography or magnetic resonance (MR) angiography .
Since a CT angiogram has a sensitivity of 100% and less invasive due to the peripheral placement of the IV line than aortagraphy it is the primary imaging choice. [4] This allows visualization of the aorta and provides precise locations of traumatic injury. [9] A CT angiogram does show both direct and indirect signs of aortic injury.
