                        rediculous.  he can have blood drawn off instead of transfused...this will help him from having a stroke.  There is also an unbrella procedure where a device is implanted that actually catches the emboli before they hit their target.  You need to see a hematologist.  There may be some chemotherapy that will help you.  Don't give up...never underestimate the power of prayer.  As you church to start a prayer chain for him...involve other churches as well.  Medicine may fail...but God does not.  Good Luck
