[Technical specification of epidural blood patch for treatment of spinal cerebrospinal fluid leakage].

Spinal cerebrospinal fluid leakage is a common cause of spontaneous intracranial hypotension. Traditional treatment methods include conservative treatment and surgical treatment, but conservative treatment is ineffective for some patients, while surgical treatment is rarely used in clinical practice due to severe trauma. Minimally invasive surgery at appropriate time is an important method to handlecerebrospinal fluid leakage. Therefore, the Group of Headache and Facial Pain, Pain Branch of Chinese Medical Association formulated this technical specification of epidural blood patch for treatment of normal dural sac tension spinal cerebrospinal fluid leakage. This paper mainly discusses the concept and mechanism, indications and contraindications, operation methods, complications and treatment methods of epidural blood patch in order to improve clinical efficacy, reduce neuralsystem complications and reduce the incidence of adverse events.
