A novel treatment for breast pseudoaneurysm in the anticoagulated patient

A 74‐year‐old woman requiring lifetime anticoagulation for antiphospholipid syndrome was noted to develop a pseudoaneurysm (PA) of the breast following core needle biopsy. She was successfully treated via thrombin injection and suffered no complications. In patients requiring anticoagulation, definitive management of PA may be desired. In appropriately selected patients, ultrasound (US)‐guided thrombin injection offers superior outcomes to alternative conservative management and obviates the need for surgical intervention.
