Much of the time spent in immediate recovery post stenting is to ensure the access site is not bleeding. The patient is generally monitored using ECG etc. Medications to prevent a blood clots from forming generally and in the stent are given directly after the stenting procedure, commonly in the form of an immediate loading dose of the potent ...
With time-of-flight (TOF) magnetic ressonance it is no longer necessary to use a contrast. The word itself comes from the Greek words ἀγγεῖον angeion 'vessel' and γράφειν graphein 'to write, record'. The film or image of the blood vessels is called an angiograph, or more commonly an angiogram.
The risk increases with the exposure time, consisting of 1) time guiding the probe into and out of the heart and 2) time illuminating the contrast agent to perform the angiogram. Absorbed radiation is also a function of body mass index, with obese patients having twice the dose of normal-weight patients; exposure to the operator was also ...
Angioplasty recovery consists of avoiding physical activity for several days after the procedure. Patients are advised to avoid heavy lifting and strenuous activities for a week. [32] [33] Patients will need to avoid physical stress or prolonged sport activities for a maximum of two weeks after a delicate balloon angioplasty. [34]
Once at the level of the uterine artery an angiogram with contrast is performed to confirm placement of the catheter, and the embolizing agent (spheres or beads) is released. As more embolizing agent is administered, blood flow will slow down significantly. Over time, the decreased blood flow causes the fibroid to shrink.
A PCI involves performing a coronary angiogram to determine the location of the infarcting vessel, followed by balloon angioplasty (and frequently deployment of an intracoronary stent) of the stenosed arterial segment. In some settings, an extraction catheter may be used to attempt to aspirate (remove) the thrombus prior to balloon angioplasty.

Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
