PURPOSE We retrospectively evaluated the survival of patients with brain metastases from advanced gastric cancer (AGC) after radiosurgery (RS). METHODS Between 1998 and 2007, a total of 11 patients (median age, 61 years; range, 36-70) were diagnosed with brain metastasis from AGC and treated with RS. Each of five (46%) patients had two brain metastases.(More)
OBJECTIVE We analyzed our clinical experience with patients with intracranial hypotension and developed a strategic model for the diagnosis mainly using Radioisotope (RI) cisternography and treatment of spontaneous intracranial hypotension (SIH). METHODS AND MATERIALS We retrospectively analyzed our clinical experiences with 30 cases of SIH from January(More)
PURPOSE We retrospectively evaluated the effect of brain atrophy on the outcome of patients after a large cerebral infarct. METHODS Between June 2003 and Oct 2008, 134 of 2975 patients with stroke were diagnosed as having a large cerebral infarct. The mean age of the patients was 70 (21-95) y. The mean infarct volume was 223.6±95.2 cm(3) (46.0-491.0). The(More)
OBJECTIVE We retrospectively evaluated whether antiplatelet preparation lowered the thromboembolic complication rate during the perioperative period. METHODS We reviewed 328 elective coil embolization procedures in which only microcatheters were used for coiling. No antiplatelet medication was prescribed before the procedure in 95 cases (29%, group 1),(More)
OBJECTIVE We retrospectively evaluated the survival outcome of patients with brain metastasis from hepatocellular carcinoma (HCC). METHODS Between 1991 and 2007, a total of 20 patients were diagnosed as having brain metastasis from HCC. The mean age of the patients was 55 +/- 13 years, and 17 (85.0%) were men. Seventeen (85.0%) patients had already(More)
OBJECTIVE With improved technology, the values of intraoperative computed tomography (iCT) have been reevaluated. We describe our early clinical experience with a mobile CT (mCT) system for iCT and discuss its clinical applications, advantages and limitations. METHODS Compared with intraoperative magnetic resonance imaging, this mCT system has no need for(More)
OBJECT Moyamoya disease (MMD) is a rare cerebrovascular disease and its natural history is still unclear. The authors aimed to investigate the natural course of hemodynamically stable cases of adult MMD, with the analysis of stroke risk factors. METHODS Two hundred forty-one patients were included in this retrospective study. One hundred sixty-six (68.9%)(More)
BACKGROUND The fate of the contralateral unaffected side of the surgically treated unilateral moyamoya disease (MMD) in adults has not been well described due to the limited number of cases and the heterogeneous ages and treatment methods. The aim of this study was to evaluate the contralateral angiographic progression rate and its risk factors in(More)
We investigated the safety and clinical applicability of 7.0 Tesla (T) brain magnetic resonance imaging (MRI) in patients with brain tumors. Twenty-four patients with intraaxial or extraaxial brain tumors were enrolled in this study. 7.0T MRIs of T2*-weighted axial and T1-weighted coronal or sagittal images were obtained and compared with 1.5T brain MRIs.(More)
OBJECTIVE The purpose of this study was to assess the risk factors of prospective symptomatic haemorrhage in a large series of adult patients with cerebral cavernous malformation (CM). METHODS Three hundred twenty-six patients >18 years of age with 410 CMs were evaluated retrospectively. Symptomatic haemorrhage was defined as new clinical symptoms with(More)
