Contraction band necrosis is most likely to be seen in which clinical scenario?

Contraction bands are intensely eosinophilic transverse bands of hypercontracted sarcomeres. They occur when calcium-rich blood is restored to dead or dying cells (reperfusion), causing them to contract one last time and lock in place.
