OBJECTIVE Remote cerebellar hemorrhage (RCH) is one of the rare complications occurring after supratentorial surgery, and its pathomechanism is poorly understood. We report 10 cases of RCH from our institution and review 154 cases from a database in order to delineate incidence, common presentation, risk factors, and outcomes of this complication. In(More)
OBJECTIVE This study investigated the outcome of early shunt placement in patients with poor-grade subarachnoid hemorrhage and the effect of intraventricular hemorrhage (IVH) and high proteinaceous cerebrospinal fluid (CSF) on subsequent shunt performance. METHODS This study included 33 consecutive patients with initial Fisher grade (3/4) subarachnoid(More)
Although many procedures have already been performed to mobilize and reconstruct the temporal muscle for pterional craniotomies, the authors described a novel cortical osteotomy technique for creating and mobilizing a cortical bone slat along the superior temporal line with the temporal muscle attached to it. Screw fixation of the cortical bone slat then(More)
Patients with traumatic subdural hygroma (SDG) are at an increased risk of developing chronic subdural hematoma (CSDH). However, the mechanism by which this occurs is still not fully understood. The purpose of this paper is to investigate the clinical characteristics and pathogenesis of CSDH, as well as the relationship between CSDH and SDG. We review the(More)
Accessory middle cerebral artery (MCA) is an infrequent vascular anomaly of the brain. Cerebral aneurysms associated with this anomalous artery are also very rare. To our knowledge, there have only been ten previous reports of an aneurysm associated with accessory MCA. The authors present two patients with accessory MCA-related aneurysms. A 38-year-old male(More)
OBJECTIVE We investigated the relationship between fibrinolytic factors and computed tomography (CT) findings in patients with chronic subdural hematomas (CSDHs). METHODS Thirty-one patients with CSDHs were divided on the basis of CT findings into heterogeneous and homogeneous groups. A sample from the subdural hematoma was obtained at surgery to measure(More)
BACKGROUND An intracranial stump of an occluded vessel is a rare but important aneurysm mimic. We present 2 cases of middle trunk atresia of the trifurcated MCA, in which the proximal stump of the atretic vessel mimics an MCA bifurcation aneurysm in angiograms. CASE DESCRIPTION Both patients were referred to the authors with a presumptive diagnosis of an(More)
OBJECTIVE This study investigated the incidence and risk factors for the postoperative occurrence of subdural complications, such as a subdural hygroma and resultant chronic subdural hematoma (CSDH), following surgical clipping of an unruptured aneurysm. The critical age affecting such occurrences and follow-up results were also examined. METHODS The case(More)
We reviewed and compared the clinical course and long-term prognosis of patients with non-aneurysmal subarachnoid hemorrhage (SAH) with and without a perimesencephalic pattern of hemorrhage on CT scan. In 876 patients with spontaneous SAH, 52 (5.9%) were diagnosed with non-aneurysmal SAH. Based on their CT scans, the SAH was classified as perimesencephalic(More)
The aim of this study was to compare the effectiveness of gamma knife radiosurgery (GKS) for the treatment of multiple brain metastases from lung cancer with that of whole brain radiation therapy (WBRT). Patients with multiple (2-20) brain metastases were divided into two groups for initial brain tumor management: a GKS group (14 patients) and a WBRT group(More)
