You'll need to go to your GP, or ask the staff at the hospital.
No-one here is medically qualified to give any advice.

I hope you have a good result.

Depends on the cause of the blockage. If it's a constriction of tissue, a Stent is sometimes used:

However, your cardiologist/vascular specialist will be better able to explain the options and their risks associated with any treatment. We are not medical specialists with your fathers case notes to hand.

If the blockage is a clot then clot dissolving drugs may be indicated.

Your dad's consultant at the hospital where the angiogram was done must be your first line of enquiry. Your GP will also have been informed of the result but may not be able to advise on the most appriate course of treatment.

As above.

But there is also a treatment where they insert a long endoscope (usually via a small cut in the leg) and use this to position an inflatable "balloon" at the point of the blockage.
When inflated, this stretches the artery and can clear the blockage.

The balloon is then deflated and removed.


No doubt the hospital will do further tests prior to deciding which form of treatment to carry out.

Good luck
