Pulsatile Mass: Ruptured Common Femoral Artery Pseudoaneurysm with Active Extravasation.

Delayed rupture of a pseudoaneurysm represents an extremely rare and life-threatening complication of endovascular, radiographic, and cardiac procedures. We discuss a case of a 69-year-old man with delayed rupture of a known left common femoral artery pseudoaneurysm, highlighting the importance of rapid recognition, to include the use of point of care ultrasound, if available. Computed tomographic angiography allows for better anatomic characterization and aids in operative planning, which is the mainstay of treatment. However, surgical repair in ruptured pseudoaneurysms remains a high-risk procedure.
