Abstract
Dural substitutes are used to achieve watertight closure of the dura mater when adequate closure is not possible. The purpose of this study was to evaluate the efficacy and safety of a new collagen matrix dural substitute (Duradry, Technodry, Belo Horizonte MG) in the repair or expansion of cranial and spinal dura mater. Thirty patients, operated on between March and September, 2008, were studied. Surgical records were reviewed for sex, age, location of graft, technique, and presence of fistula or infection. The patients were followed up for at least 3 months, and presence of complications, such as cerebrospinal fluid leakage, infection, aseptic meningitis hydrocephalus, pseudomeningocele, was analyzed. Only one patient presented cerebrospinal fluid fistula. No patients presented wound infections, hydrocephalus, pseudomenigocele, meningitis, brain abscesses or signs of toxicity related to the dural substitute. The new dural substitute used in this study is effective and safe, and the initial results are similar to those of other dural substitutes reported in the literature.
