Spontaneous Intracranial Hypotension (SIH) is a condition characterized by a decrease in the pressure of the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord, occurring without any significant trauma or medical intervention. This low pressure typically results from fluid leaking through a spontaneous small tear or hole in the membrane surrounding the spinal canal (the dura mater). The reduction in CSF volume causes the brain to lose its \"cushioning\" support within the skull, leading the brain to sag downward and exert pressure on pain-sensitive structures.<\/p>\n\n\n\n
The most typical and diagnostic symptom of the condition is an \"orthostatic headache.\" This pain begins severely shortly after a person stands up or sits down but disappears completely or significantly subsides when lying down. The headache is frequently accompanied by symptoms such as neck pain, nausea, sensitivity to light and sound, ringing in the ears (tinnitus), or hearing changes. Contrast-enhanced brain and spinal MRI imaging are primarily used in the diagnostic process; characteristic signs such as enhancement of the meninges and brain displacement are sought in the MRI findings.<\/p>\n\n\n\n
The first step in the treatment of SIH usually involves conservative (non-surgical) methods such as bed rest, high fluid intake, and caffeine consumption. In cases where these methods are insufficient or the leak persists, a procedure called an \"Epidural Blood Patch\" is performed. In this procedure, the patient's own blood is injected into the leakage site in the spinal canal to act as a plug, allowing the tear to close on its own. In rarer and more persistent cases, microsurgical methods are utilized to directly close the site of the leak. Early diagnosis is critical for rapidly restoring the patient's quality of life.<\/p>\n","protected":false},"excerpt":{"rendered":"
