OBJECTIVE
Spontaneous intracranial hypotension (SIH) is an important cause of orthostatic headaches caused by spinal CSF leaks. It has a strong negative impact on patients' socioeconomic status and health-related quality of life (HRQOL). This study aimed to analyze the impact of surgical and endovascular treatments on patients' HRQOL.
METHODS
The authors conducted a prospective, observational cohort study that included all patients treated for SIH with microsurgery or embolization, depending on the type of CSF leak, at their institution between April 2022 and May 2023. Patients were asked to complete a specifically designed questionnaire, as well as the 15D HRQOL questionnaire, before and 3 months after treatment.
RESULTS
A total of 21 patients (14 female; mean age 51.7 years) were treated in the study period. There were 12 (57%) type 1 leaks, 3 (14%) type 2, and 6 (29%) type 3. While 20 (95.2%) leaks were localized in the thoracic spine, only 1 (4.8%) was found in the lumbar spine. All patients completed the questionnaires. Fifteen (71.4%) patients underwent microsurgery and 6 (28.6%) endovascular embolization. The mean 15D score improved from 0.802 before to 0.889 after treatment (p = 0.013). Compared with an age- and sex-matched general population, HRQOL was significantly impaired in patients with SIH before treatment. After treatment, the authors found no significant difference in the overall HRQOL between patients and the healthy population. Mean headache intensity on a numeric rating scale improved from 8.1 before treatment to 2.3 after treatment (p = 0.003). Patients reported that SIH had a notable impact on their social and working life.
CONCLUSIONS
SIH has a considerable negative impact on HRQOL. Microsurgery or embolization can dramatically improve HRQOL, subjective perception of health, and headache intensity. Therefore, surgical or endovascular treatment should be considered given the improvement observed in HRQOL for patients with SIH.
