Comparison of clinical characteristics with spontaneous intracranial hypotension complicated with subdural hematoma between surgical treatment and non-surgical treatment.

OBJECTIVES: The aim of this current study was to analyze the possible surgical predictive factors about spontaneous intracranial hypotension (SIH) complicated with subdural hematoma (SDH). METHODS: 178 patients diagnosed with both SIH and SDH were retrospectively reviewed. All the participants were divided into as EBP group (BPG) and surgical treatment group (STG). The demographic, clinical manifestations, radiographic and treatment data of the two groups were collected and compared by the electrical medical history system. RESULTS: The male patients accounted for the majority in the STG (77.88 %), which was significantly larger than those in the BPG(p = 0.004). Patients who regularly smoked and drunk alcohol in the STG group were significantly greater than those in the BPG group (p(smoking)= 0.049, p(drinking)= 0.014). The headache occurring in the temporal position in the STG accounted for 44.44 % which was significantly greater than those in the BPG (25.17 %, p = 0.040). The durations days of symptoms were 54.85 ± 34.78 and 33.72 ± 34.97 in the STG and BPG respectively (p = 0.005). The midline shift degree in the STG was also significantly greater than that in the BPG (p = 0.001). The largest hematoma depth in the STG was significantly greater than that in the BPG (p = 0.000). The frequency of blood patch in the STG was significantly greater than that in the BPG(p = 0022). CONCLUSION: Male, unhealthy living habits, temporal headache, duration of headache, midline shift, hematoma depth and blood patch frequency were possible related factors with the poor outcome of blood patch and surgical treatment.
