Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Ultrasound-guided injection of thrombin into a pseudoaneurysm sac to trigger immediate localized clotting and obliterate the cavity without surgery. Typical procedural contexts include femoral and other access-site pseudoaneurysms.
What most clearly distinguishes it from similar devices?
Key distinctions
Thrombin injection treats the pseudoaneurysm sac by inducing immediate localized thrombosis under ultrasound guidance, rather than closing the original arteriotomy with a mechanical access-site device.
