Doctrine of head injury sequelae

In this article, we provide the definitions of “sequelae” and “complications” of traumatic brain injury (TBI). We have developed the classification principles for TBI consequences and described their clinical forms and morphological substrates. We also provide a radiological grading for assessing the severity of sequelae of focal and diffuse brain injuries. The article covers conceptual approaches, technologies, and results of their application related to leading surgically significant consequences of TBI, including carotid cavernous fistulas, chronic subdural hematomas, post-traumatic hydrocephalus, long-term basal liquorrhea, and skull defects. We have developed the doctrine of sequelae of TBI.
