Blood Patch for Post-Surgical Cerebrospinal Fluid Leak: A Case Report

Intracranial hypotension syndrome may occur secondary to Cerebrospinal Fluid Leak (CSFL). Its etiology can be iatrogenic, traumatic or spontaneous. The most common cause is related to incidental or intentional punctures during anesthetic approaches. It is a rare complication during lumbar spine surgery. The clinical manifestations of this syndrome are characterized by orthostatic headache as the most frequent symptom, accompanied by a wide variety of manifestations, which frequently result in a disability for daily life activities and a delayed recovery. Diagnosis is made through a detailed medical history, the presence of symptoms and signs, and additional imaging studies. Initial treatment is conservative; however, using a hematic patch is recommended for a significant number of patients as the next step, reserving surgical treatment for cases that are not resolved with these measures. This paper presents the clinical case of a 56-year-old female patient diagnosed with CSF fistula following a surgical procedure, which is treated by applying a blood patch with complete remission of symptoms; similarly, a therapeutic algorithm is proposed for the diagnosis of CSFL.
