Thirty-six spontaneous intracranial hypotension patients with multiple-level leakages of cerebrospinal fluid were enrolled in the study.After 30 patients received targeted epidural blood intervention for 2 times and 6 patients received targeted epidural blood intervention for 3 times,the clinical symptoms were completely relieved.During injection of autologous blood,pain at the puncture site occurred in 24 cases,radiating pain in upper extremities in 5 cases,numbness in the upper extremity in 9 cases,radiating pain in lower extremities in 6 cases,numbness in lower extremities in 7 cases,headache in 4 cases,dizziness in 3 cases and transient bradycardia in 3 cases.Most of these symptoms were self-relieved after the end of injection or after slowing the injection rate,and some were self-relieved hours later.Neck stiffness was found in 2 cases and self-relived within a few hours or days after operation,and no severe nervous systemrelated complications were found.Recurrence happened in 2 cases at 3 months after the end of treatment,and the symptoms were self-relieved after receiving targeted epidural blood intervention for a second time.The patients were followed up for 15-36 months,and no serious nervous system-related complications were observed.Therefore,targeted epidural blood intervention is safe and effective when used to treat spontaneous intracranial hypotension caused by multiple-level leakages of cerebrospinal fluid in patients.
