Hip Fracture-Dislocation (pipkin Type Iv) Associated With an Apparent Traumatic Aortic Valve Rupture. Case History

Abstract

Traumatic aortic valve rupture with resultant aortic insufficiency is a rare complication of blunt trauma. Here reported is a case with a posterior fracture-dislocation of the hip (Pipkin type-IV) and an undisplaced sternum fracture who developed hemodynamic instability in the clinical follow-up and was diagnosed having a traumatic aortic valve rupture using echocardiography. He first was treated with a biological valve replacement. Two weeks later a total hip arthroplasty combined with the osteosynthesis of the posterior wall of the acetabulum was performed. Sternum fracture healed conservatively. In multiply injured patients especially with a blunt thorax trauma hemodynamic instability despite appropriate fluid replacement should rise the suspicion of cardiac injuries, especially traumatic aortic valve rupture. Echocardiography is a simple but reliable method for the diagnosis.
