Formation of a Pseudoaneurysm after a .22 Caliber Bullet Embolized to the Left Femoral Artery: A Case Report.

ABSTRACT

Bullet embolization is a rare and potentially life-threatening complication of gunshot wounds, particularly in lowpowered and small-caliber bullets. When these small bullets enter a large elastic vessel, they have the potential to leave a small entrance hole that can form a traumatic pseudoaneurysm. These pseudoaneurysms, which may be life-protecting at first, may rupture and lead to exsanguination if not found. We report an interesting case of an 18-year-old male gunshot victim where a bullet formed an aortic pseudoaneurysm and subsequently embolized and present a review of the literature regarding bullet embolization and traumatic pseudoaneurysms.
