When you get home after angioplasty for renal artery disease, or renal artery stenosis (RAS), you should monitor the puncture site in your skin where the catheter was inserted. After an interventional procedure such as angioplasty for RAS, it is normal to have a bruise or discolored area near where the catheter was inserted. At the same site, there may also be a small lump (which should not get bigger), soreness when pressure is applied, and perhaps a small amount (one or two drops) of discharge.
When to call the doctor:
- If the puncture wound gets bigger, turns red, drains a thick yellow/brown material, or is painful, even when no pressure is applied. A larger, painful lump may be a sign that the puncture hole is not healing properly or is leaking blood.
- If you have fever.
- If you experience swelling - with or without pain - anywhere in the leg in which the catheter was inserted.
