The aim of this review is to determine the efficacy and optimal strategy for epidural blood patch placement in the treatment of spontaneous intracranial hypotension. We present a 37-year-old man who developed a 4 week duration postural headache without sustaining significant trauma. The diagnosis of spontaneous intracranial hypotension with associated subdural hygromas was confirmed with lumbar puncture and radiologic imaging. ⋯ No clear evidence exists on comparative efficacy due to paucity of randomized trials. However, epidural blood patches in general result in positive outcomes with overall efficacy near 90%. Some trials have suggested greater efficacy for targeted rather than blind epidural blood patches, but randomized studies and long-term prognosis remain to be evaluated.

Ventriculoperitoneal (VP) shunt placement is used to treat hydrocephalus. Shunt migration following VP shunt placement has been reported. The risk factors related to this complication have not been previously evaluated to our knowledge. ⋯ Body mass index >30 kg/m(2) and number of previous shunt procedures were found to be independent risk factors for distal catheter migration. Obesity and number of previous shunt procedures were factors for distal catheter migration. Providers and patients should be aware of these possible risk factors prior to VP shunt placement.
