Spontaneous intracranial hypotension (SIH) is characterized by postural headaches without obvious cause and is occasionally related to chronic subdural hematomas (CSHs). Brain sag due to decrease in cerebrospinal fluid, and growing CSHs may occur secondary to a decrease in intracranial pressure. Therapy for this condition differs from that for mere traumatic CSHs and is controversial. We report 2 cases of CSH related to SIH. One patient required drainage of the CSHs and an epidural self-blood patch. Furthermore, this patient had to undergo reoperation for drainage of the CSHs. The other patient was cured after the first time the CSHs were drained.
自发性颅内低压（SIH）的特征是无明显原因的体位性头痛，偶尔与慢性硬膜下血肿（CSH）有关。脑脊液减少导致脑下垂，颅内压降低可能继发CSH增大。这种情况的治疗与单纯创伤性CSH的治疗不同，且存在争议。我们报告2例与SIH相关的CSH病例。1例患者需要引流CSH并进行硬膜外自体血补片治疗。此外，该患者不得不再次手术引流CSH。另一例患者在首次引流CSH后治愈。
