When I had my very first Angiogram back in 2007 after my first heart attack both the Angiogram and the subsequent Angioplasty a few weeks later were done via the groin it was the default option in the Catheter Suite at Derby Royal.
I was given the option the Nurse would shave my "Tackle"or do it myself - I opted to do it myself followed by an inspection by the Nurse who did the bit I had missed - my hairy bum area.(Think last frozen chicken at the bottom of the freezer to picture the scene)
I have now had about (lost count) about four/five Angiograms & four/five/six subsequent Angioplasty procedures done this way so as I knew the routine I always did the shave myself the night before.
When I got my appointment for another Angiogram in Jan 2020 I did the necessary preparation the day before only for them to go in radially via my left arm!
Yep I should have shaved my armpits instead.
I am happy to report that they now combine the Angiogram with the Angioplasty into the same Catherterisation so its a first time fix event being done radially whenever possible.
