Requirements for Cerebrovascular Surgery in Comprehensive Stroke Centers in South Korea.

Objective: Cerebrovascular disease (CVD) was the third most common cause of death in South Korea in 2014. Evidence from abroad suggests that comprehensive stroke centers play an important role in improving the mortality rate of stroke. However, surgical treatment for CVD is currently slightly neglected by national policy, and there is still regional imbalance in this regard.

Korean Clinical Practice Guidelines for Aneurysmal Subarachnoid Hemorrhage.

Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs.

Epidural Fluid Collection After Percutaneous Endoscopic Lumbar Discectomy.

Objective: The frequency and extent of epidural fluid collection after percutaneous endoscopic lumbar discectomy (PELD) have not been previously described. The purpose of this study was to evaluate the significance of epidural fluid collection after PELD.

Methods: From March 2008 to November 2015, immediate postoperative magnetic resonance imaging (MRI) of 464 consecutive patients, comprising 284 men and 180 women, were obtained after PELD.

Thromboembolic complication following neurointervention in ruptured anomalous hyperplastic anterior choroidal artery aneurysm.

The anterior choroidal artery (AchA) is an important cerebral artery despite its small diameter and relatively short course, because it provides blood supply to several important structures. Hyperplastic AchA is an extremely rare anomaly, and its clinical significance is the increased occurrence of intracranial aneurysm formation compared with an ordinary AchA. Because it has many small choroidal branches, subtle injury to the artery may result in severe complications.

Adjacent segment disease after interbody fusion and pedicle screw fixations for isolated L4-L5 spondylolisthesis: a minimum five-year follow-up.

Study Design: A retrospective study.

Objective: The purpose of this study are (1) to analyze prevalence of clinical and radiologic adjacent segment diseases (ASD), (2) to find precipitating factor of clinical ASD in each isthmic and degenerative spondylolisthesis groups, and (3) to compare clinical and radiologic change in isthmic and degenerative spondylolisthesis.

Summary Of Background Data: There is no clinical report regarding the use of magnetic resonance imaging (MRI) for evaluating ASD in patient who underwent 360° fusion with single-level spondylolisthesis with healthy adjacent segment.

Radiological findings of spinal schwannomas and meningiomas: focus on discrimination of two disease entities.

This study evaluates the effectiveness of CT and MR imaging in differentiating intradural extramedullary spinal schwannomas and meningiomas in a large group of patients. In addition, the study correlates tumour location, morphologic characteristics and enhancement pattern. From January 2000 to June 2007, we retrospectively reviewed 128 consecutive patients (51 male, 77 female; mean age at admission 53.

Evidence for rat organic anion transporter 3 association with caveolin-1 in rat kidney.

The rat organic anion transporter 3 (rOAT3) has recently been identified as the third isoform of the OAT family. The mechanisms that regulate rOAT3's functions remain to be elucidated. rOAT3 contributes for moving a number of negatively charged organic compounds between cells and their extracellular milieu.
