twincam,
sorry to hear of your ordeal.
Bleeding is a complication of heart catheterization. You have a very severe sequelae from your event. Even with the most meticulous care, the puncture of the artery is still a blind event and can result in bleeding in the most experienced hands. Factors that increase the risk of bleeding include obesity and the use of various blood thinners.
I would work with a neurologist and a rehabilitation specialist to try to attempt to get you back to work.
good luck
I always tell him that I can't take a chance on messing up my femoral artery, as my legs and agressive cholesterol meds are keeping me alive.
Both times that I was cathed it took about a month to get back to normal - of course that's nothing like your situation.
I just don't think that the risk is properly assessed or related to patients prior to these procedures.
Good Luck.
