Occult arterial bleeding associated with cardiac device implantation.

The appearance of hematomas or hemorrhages after the implantation of a cardiac implantable electronic device (CIEDs) is a well-known early complication, which can be associated with reinterventions, infections, readmissions, and longer hospital stays. Occasionally, these bleedings may correspond to arterial hemorrhages, which require early identification and specific treatment. We reviewed two clinical cases of inadvertent arterial bleeding after Pacemaker implantation that required a high clinical suspicion together with a multidisciplinary evaluation of cardiologists, radiologists and interventional medicine that allowed a fast and effective endovascular approach.
