Spina bifida and intraspinal lipomas.

Experience with nine consecutive cases of intraspinal lipomas revealed some unreported observations. The results of surgery are discussed with regard to pathology, timing of surgery and a modified surgical technique. Earlier compared to later operative intervention produces less bleeding, shorter operation time, easier removal of softer lipoma and easier reconstruction of conus and cord after removal of mass. Adequate dura cover can always be obtained by stripping off the dura from the fibro fatty stalk of lumbosacral lipoma. Watertight closure of dura prevents cerebrospinal fluid (CSF) leak and is ensured by the use of continuous monofilament suture material such as prolene.
