Direct complications of repeat median sternotomy in adults.

Whilst the potential risk to underlying vital structures from redo-sternotomy is well recognized, the actual risk is poorly quantified. Our aim was to determine the incidence of complications directly attributable to redo-sternotomy and to ascertain whether the use of femoro-femoral CPB (FF) prior to redo-sternotomy alters operative morbidity and mortality. Case notes of 185 patients undergoing cardiac surgery necessitating redo-sternotomy between May 1998 and November 2002 were reviewed.
