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.
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 trans
More possible conditions should be taken into consideration as haematoma is discovered, and timely treatment might prevent severe adverse events.
Core Tip: Haematoma is one of the main complications of permanent pacemaker implantation. We report a case of patient with permanent pacemaker implantation that presented with a haematoma without the conventional presentation of a pocket haematoma. After further examination, the subclavian artery pseudoaneurysm caused by puncture was found. The haematoma was successfully relieved after transcatheter arterial embolization. This case is a rare clinical condition, and the haematoma occurring in this situation is often not easily detected in clinical practice and cannot be treated in a timely and effective manner. Clinicians are reminded that when haematoma-related manifestations occur after permanent pacemaker implantation, as more possibilities are considered, timely targeted treatment can avoid serious adverse events.
