Management of Recurrent Cerebral Aneurysm after Surgical Clipping : Clinical Article.

Objective: Surgical clipping of the cerebral aenurysm is considered as a standard therapy with endovascular coil embolization. The surgical clipping is known to be superior to the endovascular coil embolization in terms of recurrent rate. However, a recurrent aneurysm which is initially treated by surgical clipping is difficult to handle.

Multiple Intracranial Aneurysms Associated with Behçet's Disease.

Behçet's disease is an inflammatory disorder involving multiple organs. Its cause is still unknown, but vasculitis is the major pathologic characteristic. The common vascular lesions associated with Behçet's disease are aneurysm formation, arterial or venous occlusive diseases, and varices.

Clinical analysis of giant intracranial aneurysms with endovascular embolization.

Objective: The purpose of this study was to perform a clinical analysis of nine patients with giant aneurysms managed with endovascular embolization.

Methods: From March 2000 to September 2009, nine cases of giant intracranial aneurysms were treated (five unruptured and four ruptured). The nine patients included two males and seven females who were 47 to 72 years old (mean, 59.

Symptomatic myelopathy caused by ossification of the yellow ligament.

Objective: This study was performed to describe the clinical presentation, surgical outcome in patients with symptomatic myelopathy caused by ossification of the yellow ligament (OYL).

Methods: The authors reviewed consequent 12 patients in whom posterior decompressive laminectomies were performed for OYL from 1999 to 2005. Diagnostic imagings including simple radiographs, computed tomography and magnetic resonance images were performed in each case.

Paraspinal Muscle Sparing Versus Percutaneous Screw Fixation: A Comparative Enzyme Study of Tissue Injury during the Treatment of L4-L5 Spondylolisthesis.

Objective: Screw fixation via the paraspinal muscle sparing approach and by percutaneous screw fixation are known to diminish the risk of complications, such as, iatrogenic muscle injury as compared with the conventional midline approach. The purpose of this study was to evaluate tissue injury markers after these less traumatic screw fixation techniques for the treatment of L4-L5 spondylolisthesis.

Methods: Twenty-two patients scheduled for posterior lumbar interbody fusion (PLIF) at the L4-L5 segment for spondylolisthesis were prospectively studied.

Incidence rate of Aneurysmal SAH in Gwangju City and Jeollanamdo Province in 2007.

Objective: The incidence of subarachnoid hemorrhage (SAH) worldwide varies considerably. In spite of many reports about the incidence of SAH, there has been no report about the incidence of SAH on the basis of the Korean population. The purpose of this hospital-based study was to assess the actual incidence rates of aneurysmal SAH in Gwangju city and Jeollanamdo province.

Large cystic cavernous angioma of the cerebellum mimicking pilocytic astrocytoma.

Objective And Importance: Cavernous angiomas are relatively rare vascular malformations. They are generally located supratentorially with a rare incidence in the cerebellum. Cavernous angiomas, accompanied by a large cyst, are very rare.

Myxopapillary ependymoma of the fourth ventricle.

Myxopapillary ependymoma is a benign variant of ependymoma, occurring almost exclusively in the cauda equina region of the back. Here, we report an extremely rare case of primary myxopapillary ependymoma, and also present our review of the existing literature. This tumor occurred in the fourth ventricle of a 62-year-old woman.
