Chronic Subdural Hematoma: Past, Present, and Future

Chronic subdural hematoma (CSDH) is a common neurosurgical condition characterized by abnormal collection of blood products in the subdural space with indolent course of progression. Its pathophysiology is complex and many theories have been put forward over time. Its presentation varies from a minimally symptomatic event to potentially serious neurosurgical emergencies. The surgical evacuation is the mainstay of its management although there has been some interest in pharmacological and minimally invasive endovascular options in this millennium. The prognosis depends on a number of factors, some of which are interdependent.
