BARBOSA, K; PEREIRA, R; TANAJURA, D  y  MELO, A. Repair of dura mater with polyesterurethane. Rev Cubana Cir [online]. 2005, vol.44, n.1. ISSN 0034-7493.

The purpose of this study was to prove the use of polyesterurethane as a dural graft material and to inform the postoperative results. Methods: A duraplasty with polyesterurethane as a graft material was performed in 30 patients that required dural implants. The polyesterurethane used was extracted from the protective polyfoam of the drug boxes. Patients with signs of infection in the site where the neurosurgical procedure was carried out were excluded. The clinical observations were made a day after surgery, at 15 and 90 days later to find signs of filtration of cerebrospinal fluid, wound infection and meningitis. Results: Neither filtration of the cerebrospinal fluid nor infection was found in any of the 30 patients (craniotomy 53.3 %, craniectomy 3.3 %, repair of depressed fractures of the cranium 20 %, repair of lumbar myelomeningocele 6.7 %, instrumentation and fusion of thoracolumbar spine 3.3 %, thoracic laminectomy 3.3 %, lumbar laminectomies 6.7 %, and lumbar discectomy 3.3 %). In a patient that was reoperated on (relapse due to cerebral metastasis), there were not observed adherences of the graft to the cortical surface. Conclusions: It seems that polyesterutherane is an appropriate dural substitute that can be easily manipulated (and in this case with no cost) and that produces a hermetic closure of the dura mater without complications or adherences to the cortical surface. Key words: Duroplasty, dural substitute, polyesterurethane

Palabras clave : Duraplastia; sustituto dural; poliesteruretano.
