    Groin Swelling After Angiogram: Pseudoaneurysm Warning Signs

    Learn when groin swelling, bruising, pain, a pulsating lump, or leg symptoms after angiogram or catheterization may need urgent assessment and vascular ultrasound.

    What a pseudoaneurysm means

    A pseudoaneurysm can occur when an artery wall is injured and blood collects outside the vessel while still communicating with the artery. It can happen after catheter-based procedures, especially around the femoral artery in the groin.

    Warning signs after angiogram

    Groin swelling, unusual or worsening pain, a pulsating lump, expanding bruising, skin change, numbness, leg weakness, cold foot, or dizziness after a procedure should be taken seriously. Severe pain, rapid swelling, bleeding, fainting, or a cold painful leg needs urgent care.

    How ultrasound helps

    Duplex ultrasound can distinguish a simple hematoma from a pseudoaneurysm, assess flow in the sac and neck, and document surrounding vessels. Management is decided by the treating vascular or cardiology team.
