What does this intervention involve?

Background and indications

A pseudoaneurysm (false aneurysm) may form after arterial catheterization, surgery or trauma, most commonly at the femoral artery. If it does not close spontaneously or with compression, thrombin injection is offered.

Benefits

Quick, effective (>95% success) and minimally invasive treatment, performed at the bedside using ultrasound.

Procedure

Under ultrasound guidance, a fine needle is introduced into the pseudoaneurysm cavity. Thrombin (clotting agent) is slowly injected, causing near-immediate thrombosis. The procedure lasts 10-20 minutes.

Risks

Native artery thrombosis (rare), distal embolization, recurrence. Allergic reaction to thrombin (exceptional).

Recovery and follow-up

Follow-up ultrasound at 24-48 hours to confirm complete thrombosis. No specific hospitalization if the patient is already outpatient.

Practical information

Local anesthesia. Outpatient procedure (return home the same day).
