RT Journal Article SR Electronic T1 But Did You Use HydroCoil? Perianeurysmal Edema and Hydrocephalus with Bare Platinum Coils JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 299 OP 300 DO 10.3174/ajnr.A0877 VO 29 IS 2 A1 J.B. White A1 H.J. Cloft A1 D.F. Kallmes YR 2008 UL http://www.ajnr.org/content/29/2/299.abstract AB SUMMARY: Bioactive coils were developed to improve aneurysm packing and accelerate neointimal healing. Recent reports, however, have implicated these coils in the development of aseptic meningitis, perianeurysmal edema, and hydrocephalus. This report demonstrates that the same clinical phenomena can occur with the use of bare platinum coils.
