title: False aneurysm with median nerve palsy after iatrogenic brachial artery puncture.
abstract: We report on a case in which a patient on oral anticoagulation for her aortic valve replacement, with an International Normalised Ratio of 2.13, developed a false aneurysm of the brachial artery after a routine arterial puncture, despite direct pressure to the aspiration site. The false aneurysm was complicated by the development of median nerve palsy.
