Bilateral platysma dystonia.

Platysma dystonia is an involuntary movement of platysma muscle. It is a rare form of dystonia. In this case report, we would like to report a good result of peripheral nerve denervation for bilateral platysma dystonia case.

Progress in the treatment of unruptured aneurysms.

Recent technological progress has reduced the complication rate of unruptured aneurysm. We treated 128 unruptured aneurysms between April 2006 and March 2012. Seventy-six aneurysms (59 %) were clipped and 52 (41 %) were coil embolized.

Relationship between preoperative magnetic resonance imaging and surgical findings: aneurysm wall thickness on high-resolution T1-weighted imaging and contact with surrounding tissue on steady-state free precession imaging.

This study evaluated the aneurysm wall thickness by high-resolution T1-weighted imaging and the contact between the aneurysm and surrounding tissue by steady-state free precession (SSFP) imaging. The surgical findings were prospectively compared with these preoperative magnetic resonance (MR) imaging findings in 35 consecutive patients with 37 unruptured cerebral aneurysms (UCAs). The aneurysm wall was not visible in 13 UCAs, but was visible in 23.

Rare variant of persistent primitive hypoglossal artery, arising from the external carotid artery.

A 63-year-old man presented with an extremely rare variant of persistent primitive hypoglossal artery (PHA), which was found incidentally during examination for a contralateral asymptomatic internal carotid artery (ICA) stenosis. This anastomotic vessel arose from the external carotid artery, not the ICA, and joined the vertebrobasilar artery through the hypoglossal canal. Persistent PHA is rare and the reported incidence is 0.

Treatment selection for ruptured aneurysm and outcomes: clipping or coil embolization.

The International Subarachnoid Aneurysm Trial has shown that coil embolization achieves a better outcome for aneurysms treatable by either clipping or coil embolization. However, many ruptured aneurysms are hardly treatable by either clipping or coil embolization. Selection of either clipping or coil embolization will affect the treatment outcome for ruptured aneurysms.

Effects and complications of stereotactic aspiration for spontaneous intracerebral hemorrhage.

Stereotactic aspiration of intracerebral hemorrhage (ICH) improves the general condition of patients, promotes improvement of consciousness, and decreases the incidence of pneumonia, but may induce rebleeding. The present study investigated the effects of stereotactic aspiration and factors that inhibit rebleeding in 70 consecutive patients who underwent stereotactic aspiration for ICH. Consciousness was significantly improved after surgery.

Percutaneous vertebroplasty under three-dimensional radiography guidance. Technical note.

An accurate, safe, and convenient method for performing percutaneous vertebroplasty (PVP) under three-dimensional (3D) radiography guidance has been developed. Six PVP procedures were performed in 5 elderly stroke patients complaining of back pain caused by compressive fracture which interfered with further rehabilitation. T(1)-weighted magnetic resonance imaging showed low intensity and T(2)-weighted imaging showed high intensity in the fractured vertebral body.
