Husband has aaa stent. right groin was site of heart cath as well as aaa stent .3 weeks post op still has hard swelling.is this bad?

Not necessarily: He may have had some bleeding into the area after the cath or groin exposure for the AAA stent. If the wound is healing well and isn't red or draining this should resolve. If there is a lot of pain, redness or drainage from the wound you should call the vascular surgeon.

Not necessarily: 2 intervention via one femoral artery, can cause scar tissue, but be in touch with your cardiologist and he might order a doppler from the site.

Hematoma: It is very common to have a bruise and small collection of blood at the groin site. This can become a rubbery firm nodule after a week or so. It should not be painful, warm, or red. If you have a concern your doctor will want to see it.
