文摘

Decompressive craniectomy is a controversial surgical procedure with high failure rates. It induces large mechanical strains, which are believed to be the cause of brain damage. To quantify strains in the brain we create a personalized finite element craniectomy model. Our simulations reveal three potential failure mechanisms: stretch, compression, and shear. Our craniectomy model can identify regions at risk for brain damage on a personalized basis.
