The inpatient admissions was for a STEMI, for which the patient had been a coronary angiography and intervention.

This pseudoaneurysm was found incidentally, the patient was not symptomatic and it was successfully treated with an ultrasound guided thrombin injection. Pseudoaneurysms are reported to complicate ~1% of diagnostic coronary angiography and ~4% when intervention is performed.
