Emergent decompressive craniectomy in patients with fixed dilated pupils due to cerebral venous and dural sinus thrombosis: report of three cases.
OBJECTIVE
Cerebral venous and dural sinus thrombosis is a rare cause of stroke. Although morbidity and mortality have greatly decreased in recent years as a result of early diagnosis and timely medical treatment, when coma occurs the prognosis remains poor. We evaluated whether emergent decompressive craniectomy has a role in the treatment of patients with brain herniation from dural sinus thrombosis and hemorrhagic infarct.


METHODS
Three patients developed large hemorrhagic infarct with coma and bilaterally fixed and dilated pupils resulting from aseptic dural sinus thrombosis.


METHODS
Two patients underwent emergent surgical decompression as soon as brain herniation developed, and these patients had complete functional recovery. One underwent delayed surgical decompression and remained severely disabled.


CONCLUSIONS
Our results provide preliminary evidence that emergent decompressive craniectomy is effective in patients with brain herniation from dural sinus thrombosis, provided that the clinical onset is recent. We therefore recommend consideration of this aggressive surgical technique for such patients, who may survive with good outcomes.
