Abstract:
An 83-year-old Chinese man presented with a huge left chest wall hematoma and hemorrhagic shock 4 months after permanent pacemaker implantation. Computed Tomography of Angiogram of the left subclavian artery revealed a pseudoaneurysm. He underwent radiologically guided stenting followed by hematoma clearance. It is rare to have delayed formation of pseudoaneurysm at 4 months post pacemaker implantation. Radiologically guided stenting is the preferred treatment, followed by hematoma clearance. It is strongly advised against blind surgery for wound debridement or bleeding detection. Familiarizing with axillary vein anatomy, improving axillary vein cannulation skills, and detecting early complications of artery injury are key strategies in preventing pseudoaneurysm formation post pacemaker implantation.
