sentinel lymph node removal and "at risk" arm

I’ve had a bilateral procedure in regards to the Senitel lymph node procedure and awaiting double mastectomy so when they were taking blood and administering the anaesthetic it didn’t matter which side they proceeded with. I chose the left simply because I am right handed. Not sure if this answers your questions all.

I had a WLE and 4 nodes removed on the right side, I have no lymphoedema. A few weeks after surgery, I went into hospital to have a portacath fitted. It needed to be fitted on my left upper chest. The procedure needed me to have frequent blood pressure checks from an automated machine. They couldn’t put it on my left arm because if would have interfered with the procedure. They didn’t want to put it on my right arm. They tried my leg but it caused severe cramp and I needed to remain still for the procedure. So they gave in and put it on my right arm. I didn’t have any problems and have stopped worrying about it since. I almost always get blood taken from my right elbow anyway because it has a better vein. 

Thanks very much, that's very reassuring.

I had centinal lymph nodes taken on both sides. I decided to have a pic line inserted to help with chemotherapy. When I went to have the pic line inserted they were worried because they usually insert the pic line in the other side. My oncologist told them to insert the pic line in the best vein, I was told that there was an increased chance of problems but overall the pic line was advantageous over having to find a vein each time i needed chemotherapy. My consultant said that it was ok to use vein in either arm but when I was in hospital they did my blood pressure on my leg

Thanks, that's helpful to know.

Thanks.  I hope all goes well for you.
