Regression of asymptomatic intracranial arterial stenosis by aggressive medical management with a lipid-lowering agent.

Objective: The incidence rate of stroke as a result of intracranial arterial stenosis (ICAS) is higher in Asian countries than in the West. We aimed to analyze the regression, lack of change, or progression of asymptomatic ICAS after the administration of rosuvastatin and associated factors.

Methods: The patients who had undergone computed tomography angiography (CTA) at our hospital and had been diagnosed with ICAS with no ischemic event in the stenosed vascular territory were included in the study.

Delayed Operation of Acute Subdural Hematoma in Subacute Stage by Trephine Drainage using Urokinase.

Objective: The principle operation of acute subdural hematoma (ASDH) is a craniotomy with hematoma removal, but a trephination with hematoma evacuation may be another method in selected cases. Trephine drainage was performed for ASDH patients in subacute stage using urokinase (UK) instillation, and its results were evaluated.

Methods: Between January 2016 and December 2018, the trephine evacuation using UK was performed in 9 patients.

Multiple Intracranial High Density Foci after Brain Parenchymal Catheterization.

Objective: To report an observational investigation of small high attenuated foci in computed tomography (CT) scan followed by brain parenchymal catheterization.

Methods: From January 2011 to March 2015, we retrospectively reviewed the 381 patients who had undergone brain catheterization in our clinic and enrolled the patients who had newly developed high attenuation foci in the postoperative CT scans. The brain CT scans were reviewed about the lesion location, Hounsfield Unit (HU) and the time of appearance.

Clipping of incidental aneurysm of middle cerebral artery through small temporal craniotomy and linear skin incision.

The authors introduced a new approach for clipping of the incidental aneurysm of the middle cerebral artery (MCA) and reported the clinical results. We retrospectively reviewed 26 patients with 27 incidental MCA aneurysms who were treated from January 2010 to December 2012. All clippings were performed through a small temporal craniotomy and linear skin incision.

Factors related to catheter-induced hemorrhage after brain parenchymal catheterization.

This article aimed to investigate the incidence rate and possible risk factors for catheter-induced hemorrhage (CIH) after brain parenchymal catheterization. Between January 2011 and March 2013, 381 patients (572 punctures) who underwent brain parenchymal catheterization were retrospectively evaluated. All patients were checked by computerized tomography scan for the detection of hemorrhage within 48 hours after catheter insertion.

Intraspinal ganglion cyst.

The pathogenesis of juxtafacet cysts is closely related to degenerative instability of the lumbar spine and degenerative changes in the ligamentum flavum and the facet joint. A 56-year-old man presented with severe right thigh pain and numbness for 1 month after a laminar fracture of the L4 spine. Magnetic resonance imaging revealed a heterogenous cystic mass surrounding the facet joint between the fourth and fifth lumbar vertebrae on the right side.

Outcome evaluation of intravenous infusion of urokinase for acute ischemic stroke.

The aim of this study was to evaluate the clinical effect of a continuous infusion of urokinase in cerebral stoke patients who were late admitted over 6 hours after onset. From January to December in 2008, acute cerebral stroke patients (n=143) treated with intravenous urokinase infusion (Group I, n=93) or not (Group II, n=50) after 6 hours and within 72 hours of stroke onset were reviewed. Continuous intravenous infusion of urokinase was done for 5 days.

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.
