The authors conducted a study to determine the effectiveness of mitomycin C in preventing postlaminectomy peridural fibrosis in rabbits.
Methods
Laminectomies were performed at L-4 in 12 rabbits. Color-coded cotton pads soaked either with 0.02% mitomycin C or saline were applied in a blinded fashion to the operative sites, with saline-treated laminectomy sites serving as controls. The rabbits were killed 30 days after surgery. The extent of peridural fibrosis was evaluated by histological analysis.
The mitomycin C—treated sites showed significantly decreased peridural fibrosis.
Conclusions
Peridural fibrosis can be a devastating condition that develops after laminectomy. Topical application of mitomycin C may be a successful method of preventing postlaminectomy peridural fibrosis.
Among 1142 patients with head injuries hospitalized in the Neurosurgery Department of Gazi University Medical School during the period between 1979 and 1992, 583 had initial CT scans. A retrospective analysis of these initial CT images revealed intracranial air on admission in only 21 cases. These were classified as acute traumatic intracranial pneumocephalus: a potentially serious complication of head injury. CT scans were re-evaluated so as to reveal whether air was situated in the epidural, subdural, or subarachnoid spaces or intracerebrally; whether associated space-occupying lesions were present and whether the air bubbles were single or multiple. Clinical data such as the presence of persistent rhinorrhea and/or otorrhea, tension pneumocephalus, severity and type of trauma, and outcome were were also assessed to determine the significance of this rare finding.
Most of the patients are dead born, and the others die in a few hours. There are only six previously documented long-term survivors. In our case, our patient with iniencephalic signs and findings is still living. She is 2 years old now. We think that this patient presents a mild form of iniencephaly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
