resternotomy
Pronunciation: ree-ster-NOT-oh-mee
Reopening of the sternum for repeat cardiac surgery or emergency access.
Full Definition
Resternotomy refers to the surgical reopening of a previously divided sternum, typically for repeat cardiac operations or emergency re-exploration. This procedure carries increased risks compared to primary sternotomy due to adhesions, proximity of cardiac structures to the sternum, and potential for catastrophic bleeding. Resternotomy requires specialized surgical techniques and anesthetic considerations including availability of immediate cardiopulmonary bypass and blood products.
