ABSTRACT
Subperiosteal haematoma of the orbit is an uncommon complication of maxillofacial trauma, hence easily missed. It usually presents subacutely with proptosis and diplopia. In our case, the subperiosteal haematoma is complicated with high intraocular pressure, necessisating measures to reduce the intraocular pressure. Unresponsive to only medical treatment, surgical evacuation was carried out in this patient. Removal of the clot finally relieved the intraocular pressure and simultaneously improved the proptosis and the cumbersome diplopia.
ABSTRACT
We report the case of a severe head injured 43-year old male patient with a large extradural hematoma, Glasgow Coma Scale 3 and dilated fixed pupils. Patient was promptly submitted to surgical evacuation of the lesion, but remained in persistent vegetative state in the post-operative time. Head computed tomography scans performed before surgery, and at early and late post-operative periods comparatively revealed extreme bilateral cortical atrophy. Late consequences of severe head trauma drastically affect the prognosis of patients, being its prevention, and neuroprotection against secondary injury still a therapeutical challenge for neurosurgeons.
Relatamos o caso de um paciente de 43 anos, com traumatismo cranioencefálico grave, com grande hematoma extradural, Escala de Coma de Glasgow 3 e pupilas fixas e dilatadas. O paciente foi prontamente submetido à evacuação cirúrgica da lesão mas permaneceu em estado vegetativo persistente no período pós-operatório. As TC de crânio realizadas antes da cirurgia e nos períodos pós-operatórios precoce e tardio revelaram comparativamente extrema atrofia cerebral bilateral. As conseqüências tardias do traumatismo craniano grave afetam drasticamente o prognóstico dos pacientes, sendo sua prevenção, e a neuroproteção contra a injúria secundária ainda um desafio terapêutico para os neurocirurgiões.
