Severe Bleeding after Embolization

After my embolization surgery in October, when the nurse went to take the “needle” (not very good with medical terms) out of my arterie it took her over 2 hrs to get it to clot. After watching her release the pressure and see me squirting all over the place 3 times she ended up calling for more nurses and Doctors. No one new why this was happening. I got rushed plasma and had them all alternating putting pressure on my groin. It was very stressfull and scary! Has anyone else experianced this?
