Long-term postoperative prognosis and associated risk factors of chronic subdural hematoma in the elderly.

Surgical treatment for chronic subdural hematoma（CSDH）has contributed to good outcome. However, several recent studies have revealed that surgical outcomes for elderly patients were not decisively good. In this study, prognosis of CSDH patients in elderly were analyzed.

Extensive extracranial growth of spheno-orbital meningioma: illustrative case.

Background: Spheno-orbital meningioma (SOM) typically presents with a classic triad of symptoms (i.e., proptosis, visual impairment, and ocular paresis), resulting from intraorbital tumor invasion.

The Effect of Goreisan on the Prevention of Chronic Subdural Hematoma Recurrence: Multi-Center Randomized Controlled Study.

The relatively high rate of post-operative recurrence in the treatment of chronic subdural hematoma (CSDH) is a significant problem. Goreisan is an herbal medicine that exhibits a hydragogue effect by inhibiting the expression of aquaporins, and its efficacy in preventing post-operative CSDH recurrence has been suggested by several case trials. This multi-center prospective randomized controlled trial was performed to investigate the preventative effect of goreisan on post-operative CSDH recurrence.

Long-acting statin for aneurysmal subarachnoid hemorrhage: A randomized, double-blind, placebo-controlled trial.

Statins have pleiotropic effects that are considered beneficial in preventing cerebral vasospasm and delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage (aSAH). Many studies using statins have been performed but failed to show remarkable effects. We hypothesized that a long-acting statin would be more effective, due to a longer half-life and stronger pleiotropic effects.

Preoperative Three-Dimensional Diagnosis of Neurovascular Relationships at the Root Exit Zones During Microvascular Decompression for Hemifacial Spasm.

Objective: Hemifacial spasm occurs when a blood vessel compresses against an area near the root exit zone of the facial nerve. Developments in diagnostic neuroimaging have allowed three-dimensional (3D) observation of artery and nerve locations, an effective aid for treatment selection. However, an accurate interpretation of the 3D data remains challenging because imaging representations of complex small vessels are drowned out by noise.

Effect of Cilostazol on Cerebral Vasospasm and Outcome in Patients with Aneurysmal Subarachnoid Hemorrhage: A Randomized, Double-Blind, Placebo-Controlled Trial.

Background: Several clinical studies have indicated the efficacy of cilostazol, a selective inhibitor of phosphodiesterase 3, in preventing cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH). They were not double-blinded trial resulting in disunited results on assessment of end points among the studies. The randomized, double-blind, placebo-controlled study was performed to assess the effectiveness of cilostazol on cerebral vasospasm.

Indications and Timings of Re-operation for Residual or Recurrent Hemifacial Spasm after Microvascular Decompression: Personal Experience and Literature Review.

We reviewed reports about the postoperative course of hemifacial spasm (HFS) after microvascular decompression (MVD), including in our own patients, and investigated treatment for delayed resolution or recurrence of HFS. Symptoms of HFS disappear after surgery in many patients, but spasm persists postoperatively in about 10-40%. Residual spasm also gradually decreases, with rates of 1-13% at 1 year postoperatively.

[Basal interhemispheric approach for distal anterior cerebral aneurysms].

Purpose: To investigate retrospectively the usefulness of basal interhemispheric approach for neck clipping of aneurysms located on genu or infracallosal portion of anterior cerebral artery.

Clinical Materials And Methods: Seventeen aneurysms in 17 patietns treated by clipping with basal inter-hemispheric approach in our department for past 8 years were reviewed. Of them, 12 were ruptured aneurysm and 5 were unruptured one.

Extravasation from rupturing aneurysm demonstrated by 3D digital subtraction angiography.

We describe the 3D digital subtraction angiography (3D-DSA) image of extravasation from a rupturing aneurysm. This image clearly showed that the extravasation was coming from a pseudoaneurysm on an aneurysmal wall. To the best of our knowledge, this is the first demonstration of a 3D-DSA image of a rupturing aneurysm.

[Surgical treatment for dissecting aneurysm of the anterior cerebral artery presenting only with headache: a case report].

The authors reported the first case of a dissecting aneurysm of the anterior cerebral artery (ACA) presenting only with headache successfully treated by trapping. A 23-year-old man was admitted to our department due to headache. CT scan and MRI showed neither hemorrhage nor infarction.

Effective solitary hyperthermia treatment of malignant glioma using stick type CMC-magnetite. In vivo study.

Various kinds of hyperthermic treatment for malignant glioma had been inhibited due to both their incomplete feverish action and strict cooling effect of the brain. The author shows an effective results of hyperthermia for the treatment of malignant glioma in an in vivo study using stick type carboxymethylcellulose (CMC)-magnetite, a newly manufactured magnetite-product. A stick type CMC-magnetite, containing magnetite particles, was inserted into the T-9 glioma in the rat brain stereotactically, and the rats were exposed to an alternative magnetic field (AMF).
