Symptomatic postlaminectomy cerebrospinal fluid leak treated with 4-dimensional ultrasound-guided epidural blood patch.
A persistent cerebrospinal fluid leak after spinal surgery can be associated with both meningitis and/or pneumocephalus. Therefore, early active intervention is recommended with surgical exploration, lumbar subarachnoid drain, and less commonly epidural blood patch. In the absence of a ligamentum flavum, the use of high-resolution ultrasound (US) spine imaging enables real-time advancement of a Tuohy needle towards the dura and the precise injection of blood to cover the dural defect. ⋯ Real-time US guidance allowed accurate positioning of the Tuohy needle and deposition of the epidural blood patch in the setting of a surgically removed ligamentum flavum. Further investigations are needed to confirm that an US-guided epidural blood patch may offer reliable symptomatic relief to postsurgical persistent cerebrospinal fluid leak and may serve as an intermediate step along a spectrum between conservative initial management and surgical reexploration.
