© 2022 Elsevier Inc.Objective: To evaluate the clinical and radiological results of lumbar accessed catheter-assisted epidural blood patch (LACA-EBP) technique in treatment of spontaneous intracranial hypotension secondary to cervicothoracic cerebrospinal fluid leakage. Methods: Patients presenting with spontaneous intracranial hypotension where magnetic resonance imaging cisternography confirmed and localized the cerebrospinal fluid leakage at cervicothoracic levels were treated with LACA-EBP. Visual analog scale (VAS) score for headache at baseline, third day after treatment, and during long-term follow-up was used to assess the treatment response. Posttreatment VAS score ≤3 on the third day defined treatment success, and VAS score ≥4 indicated treatment failure. Results: LACA-EBP was performed in 10 patients (7 females, 3 males) with a mean age of 38.4 ± 10.5 years. Orthostatic headache was the most common presenting symptom (10/10; 100%) followed by nausea (5/10; 50%). Pituitary gland enlargement was the most commonly observed finding on pretreatment cranial magnetic resonance imaging (9/10; 90%). On magnetic resonance imaging cisternography, 8 patients had cervical and/or thoracic fistulas, whereas 2 patients had multiple-level fistulas. LACA-EBP was successful in all patients with no complications. All patients showed a treatment response with a 72-hour VAS score ≤3. Follow-up VAS scores were available for 8 patients with a clinical follow-up duration of 1–74 months (median 7.5 months). During clinical follow-up, headache recurred in 2 patients. Conclusions: In our study cohort, LACA-EBP was a safe and efficacious technique in treatment of cerebrospinal fluid leakage at cervical and thoracic levels.
