Pseudoaneurysm

Pseudoaneurysm (false aneurysm) is a contained rupture of an artery with blood bounded by surrounding tissue, not all three vessel layers; most often iatrogenic (after catheterization), traumatic, or mycotic. Clinical: pulsatile mass, pain, risk of rupture/thrombosis/embolism. Treatment: ultrasound-guided compression or thrombin injection for small iatrogenic pseudoaneurysms; endovascular embolization/stenting; surgical repair for large/complex/mycotic; treat infection; control anticoagulation if applicable.

Common Symptoms

Pulsatile mass; pain; rupture/thrombosis risk; by iatrogenic/traumatic/mycotic

Causes and Pathogenesis

Iatrogenic/traumatic/mycotic arterial wall breach with contained extravasation.

Treatment

Compression/thrombin for small iatrogenic; embolization/stenting/surgery for large/complex/mycotic; treat infection

Preventive Measures

Careful vascular access; treat infection; control anticoagulation.
