RT Journal Article SR Electronic T1 Contrecoup haemorrhage in a patient with left pubic fracture but right obturator artery bleeding JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 598 OP 599 DO 10.1136/emj.2007.046193 VO 24 IS 8 A1 Ying C Huang A1 Peter Liu A1 Jenn-Shyan Su A1 Yi-Lii Lin YR 2007 UL http://emj.bmj.com/content/24/8/598.abstract AB Contrecoup injury following head trauma is well known. It is caused by the acceleration–deceleration mechanism that can be fully explained by Newton’s first law of motion. We report on a victim of a motor vehicle accident with non-displacement left pubis fracture but haemorrhage from the right obturator artery. Contrecoup haemorrhage should be excluded first in unstable patients without evidence of significant trauma but with a minor pelvic fracture.
