Successful transcatheter arterial embolization treatment for chest wall haematoma following permanent pacemaker implantation:A case report

BACKGROUND Haematoma is one of the main complications associated with pacemaker implantation.Pseudoaneurysm is a rare condition that is not easy to identify and is often overlooked.CASE SUMMARY A female patient diagnosed with high-grade atrioventricular block underwent permanent pacemaker implantation.During the operation,puncturing a small branch of the right subclavian artery developed into a pseudoaneurysm and resulted in further haematoma formation.Conventional treatment of compression haemostasis and haemostatic drugs was not effective.A series of timely transcatheter arterial embolizations avoided serious complications.CONCLUSION More possible conditions should be taken into consideration as haematoma is discovered,and timely treatment might prevent severe adverse events.
