Diagnosis for fibromuscular dysplasia is dependent on the health, position of the damaged artery & various other health conditions. Usually diagnosis for this ailment includes medications, surgery & procedures.

Percutaneous transluminal angioplasty (PTA):

This process is considered to be more effective than surgery. This process can be executed at precisely the same time when an angiogram that is catheter based is being executed.

When the dye injected via the angiogram reflects the narrow area of the artery, a wire is first threaded into the artery followed by a catheter to which a balloon is attached. The balloon is inflated in the narrow part thereby expanding that area. Stents which are used in angioplasty is not necessary in this case.

Revascularization through Surgery:

When PTA is not the option & the narrowing problem is quite serious, then your doctor might advise you for a severe surgery tocure your narrowed artery.
