Review Case Reports
[Superior sagittal sinus occlusion caused by a compound depressed skull fracture: a case treated by emergency surgery].
Depressed skull fractures compressing major venous sinuses are rare, and the treatment is a matter of controversy. The majority of depressed fractures are treated conservatively for fear of bleeding from venous sinuses, but surgical intervention was conducted in a few cases. We report a case of a 59-year-old man with a compound depressed fracture occluding the superior sagittal sinus (SSS). ⋯ The patient exhibited slight disorientation and was transferred to another hospital for further rehabilitation. Because of symptomatic severe venous congestion, we had to perform emergency surgical decompression and removal of bone fragments. Treatment strategy for depressed skull fracture with SSS involvement was discussed with review of the literature.

The combination of trigeminal neuralgia and ipsilateral hemifacial spasm, known as painful tic convulsif (PTC), is a relatively rare entity in neurovascular compression syndrome. A case of PTC attributable to different offending arteries is described, the mechanisms and characteristics of PTC are discussed, and a review of the literature is presented. This 80-year-old woman had a 10-year history of left trigeminal neuralgia and ipsilateral hemifacial spasm. ⋯ Microvascular decompression of the lesions via left lateral suboccipital craniotomy resulted in immediate and complete symptom improvement. Our case demonstrates that different arteries can affect the trigeminal and facial nerve at a stage that precedes compression by a tortuous vertebrobasilar artery. We suggest that the presence of PTC should be considered in patients with a tortuous vertebrobasilar artery, irrespective of the offending arteries.

Cerebral vasospasm remains a leading cause of morbidity and increasing mortality rates following aneurysmal subarachnoid hemorrhage (SAH). The rate of vasospasm and the outcome (Glasgow Outcome Scale; GOS) especially in poor WFNS grade were retrospectively analyzed over a 6-year period. Patients were divided into three different groups. ⋯ Although the rate of favorable outcome in GOS was highest and the rate of death was least in the mil-cis group in both grade IV and V, only the trend was observed. Many factors should be considered, Cisternal irrigation therapy with milrinone reduced the occurrence of vasospasm. However, outcome was not improved because of the initial poor clinical condition.

We reviewed the records of 1,335 minor head injury patients with initial Glasgow Coma Scale (GCS) scores of 15 treated by our neurosurgery service between January 1998 and December 2000. Skull X-ray was performed in 945 patients (71%), and Computed tomography (CT) was performed in 590 patients (44%). Skull fracture was shown radiographically in 24 patients (2.5%), and abnormalities on the initial CT were seen in 29 patients (4.9%). ⋯ Patients required neurosurgical intervention in 4 cases, and all of those were acute epidural hematoma with skull fracture. In this study, the first thing we should do for asymptomatic minor head injury patients with a GCS score of 15 is to investigate the presence of a skull fracture by skull X-ray. Head trauma patients with a skull fracture and post-traumatic vomiting should undergo CT to facilitate detection of intracranial lesions, even when there are no abnormal neurological signs.

Case Reports
[Symmetrical bilateral epidural hematoma after head injury in the mid parietooccipital region: case report].
The authors presented a patient with acute symmetrical bilateral epidural hematomas, which are rare but life threatening. A 72-year-old male accidentally fell from the roof at a height of about 3 meters and hit his head against the ground. He was transferred to the emergency ward in our hospital. ⋯ Injury of both of the middle meningeal arteries was revealed to be the cause of the bilateral epidural hematomas. Clinical course after operation was uneventful and the patient was discharged without any neurological deficit. Simultaneous bilateral craniotomies and removal of the epidural hematomas would have contributed to obtaining the good result in this patient.
