There are other options for limiting bleeding risk of the spleen.
Ask your physician about intra-arterial splenic artery embolization. This would be done by an interventional radiologist, not a surgeon.
The procedure would involve a small cut in the groin and they would occlude the splenic artery (thus cutting off it's blood supply and causing it to shrink and fibrose) from a catheter inserted in your groin.
That way, you avoid the post-operative morbidity of an open laparotomy (ie. you don't get your belly cut).
They may not perform the procedure, however, depending on the population size of the city in which you live (ie. not as many specialists capable of performing the embolization).
Hope this helps.
