Neurosurgery

Neurosurgery is the surgical discipline that involves any pathology affecting the nervous system, including the brain, spinal cord, peripheral nerves, and cerebrovascular system.

Learning the basic principles of flow and pressure within the cerebrovascular system allows for a greater understanding of many of the pathologies that affect the nervous system and their sequelae. The Monro-Kellie Doctrine is a core concept of neurosurgery, describing the relationship between the contents of the cranium and intracranial pressure (and is an exam favourite too!)

Haemorrhage within the cranium can occur in various places and significantly affects patient presentation, management options, and overall outcome. As such, knowing the key features and investigation findings for subarachnoid, subdural, and extradural haematomas is essential for every clinician.

Cauda Equina Syndrome and Spinal Cord Compression are two important neurosurgical conditions that also need to be identified early and managed quickly if good outcomes are to be achieved. There are multiple causes of both these conditions, therefore ensure to learn about these important topics.
