What happens during an angiogram to fix l subclavian steal? total blockage, solid scar tissue.
A doctor has provided 1 answer
Only dye; blood flow: Angio (blood) gram (picture) is a technique to see a shadowgram of dye (absorbs X-Ray gamma rays) mixed with blood on an X-Ray sensitive film or imaging device. Results: shadows of the dye, still or motion picture. Angiograms NEVER fix anything, only a blood visualization technique & dye (filtered out of blood by kidneys over hours) can create problems. Clots→Scar tissue=always what blocks flow.
