Objective Chronic subdural hematoma is a common and relatively benign disease. However, recurrence after surgical treatment, the rate varies from 5% to 33%. The aim of this study was investigate predictive factors for chronic hematoma. Methods We analyzed data 248 patients with who were treated by burr-hole craniostomy closed drainage system evacuation in five-year retrospective study. Results Thirty-one (12.6%) underwent re-operation Univariate analysis revealed that anticoagulation...

Assessment of the collateral status has been emphasized for appropriate treatment decisions in patients with acute ischemic stroke. The purpose this study was to introduce a multiphase MRA imaging method (collateral map) derived from time-resolved dynamic contrast-enhanced and verify value map stroke by comparing it (MRP susceptibility MR perfusion. From prospectively maintained registry stroke, data caused steno-occlusive lesions unilateral ICA and/or M1 segment MCA were analyzed. We...

Mechanical thrombectomy is increasingly being used for the treatment of acute ischemic stroke. The population over 80 years age growing, and many these patients have infarction; however, are often excluded from clinical trials, so aim this study was to compare functional outcomes complication rates in very elderly (age ≥80 years) aged (60-79 treated with mechanical thrombectomy.Between January 2010 June 2015, we retrospectively reviewed 113 senior (over 60 old) at our institution stroke...

Recently, mechanical thrombectomy with stent retriever has achieved faster and higher rates of recanalization for intracranial major vessel occlusion. However, comparative studies the most widely used Solitaire Trevo stents have been rarely published. The authors retrospectively reviewed a total 200 patients who performed at our center during 4 years divided into 2 groups: (Group 1: Solitaire) 2: Trevo). All underwent clinical assessment National Institutes Health Stroke Scale (NIHSS) score...

The association between cigarette smoking and the risk of developing malignant glioma (MG) remains unclear. We aimed to evaluate this potential in a large general population, using well-established validated longitudinal nationwide database. Using data from Korean National Health Insurance System cohort, 9,811,768 people over 20 years old without any cancer history 2009 were followed until end 2017. documented 6100 MG cases (ICD-10 code C71) during median follow-up period 7.31 years. Current...

Objective To identify the accuracy and efficiency of computed tomographic (CT)-based navigation system on upper cervical instrumentation, particularly C1 lateral mass C2 pedicle screw fixation compared to previous reports. Methods Between May 2005 March 2014, 25 patients underwent instrumentation via a CT-based system. Seven were excluded, while 18 involved. There 13 males five females; resulting in four degenerative diseases 14 trauma cases. A fluoroscopy used during procedure. Among 58...

The purpose of the study was to investigate incidence, prevalence, and survival malignant gliomas (MGs) using population-based Korean National Health Insurance Database (NHID) data.Using NHID, we identified patients with MG as C71 codes in KCD 5-7 according ICD-10 from January 1, 2007 December 31, 2017. Epidemiological characteristics MG, including annual mortality rates, were collected analyzed socioeconomic state (SES) treatments received.We 45,066 newly diagnosed-MG 2017, for an...

Non-traumatic convexal subarachnoid hemorrhage (CSAH) is a comparatively infrequent with various vascular and nonvascular causes, it rarely occurs concomitant to acute ischemic stroke. We report case of 59-year-old woman, visited emergency room right side subjective weakness spontaneously. Magnetic resonance diffusion-weighted images revealed an infarction anterior cerebral arterial territory. Computed tomographic angiography showed left frontal CSAH without any lesions. And other laboratory...

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by the presence of antiphospholipid antibodies (aPLA), such as anticardiolipin (aCL), anti-β2-glycoprotein I (aβ2GPI), or lupus anticoagulant (LA). Although cerebrovascular events are commonly associated with APS, comprehensive studies on risk factors for cerebral infarction in aPLA-positive patients remain sparse. In this retrospective single-center study, data from 9844 tested aPLA between January 2017 and March 2023...

Giant intraosseous schwannoma is very rare. Schwannomas arising around the sacrum can reach a considerable size before becoming symptomatic because of their insidious and slow growth, which allow displacement nerves internal organs, often resulting in extensive bone erosion. The treatment these giant schwannomas causes significant neurological disability. A 29-year-old woman was suffering from paresthesia her left posterior thigh. Her symptom aggravated since last 5 months. Neurological...

The spot sign on computed tomography angiography is little known about the relationship between and results of cerebral We retrospectively analyzed sign, digital subtraction results, other factors.From December 2009 to May 2014, DSA was performed in 52 ICH patients with non-specific location or abnormalities CTA findings. 26 those patients, whose initial showed were analyzed. Two groups, one ventricle (Group A) others another B) statistically compared.The mean age study subjects 46.9 years...

Neoplastic cerebral aneurysms with intracerebral hemorrhage (ICH) occur very rarely in young patients, and these cases are often observed relative to metastatic choriocarcinoma. We report a case of childbearing female patient recurrent ICHs, who was presumed be choriocarcinoma present review the literature. A 35-year-old woman visited emergency room ICHs left basal ganglia, parietal lobe, intraventricle. However, no vascular abnormalities were found initial magnetic resonance (MR)...

To compare the clinical outcomes of Target 360 nano (TG) and Microplex hypersoft 3D (MH) used as a finishing coil (FC).From January 2018 to December 2020, we retrospectively reviewed 243 embolization procedures performed using TG (n=152) MH (n=91) coils 1mm x 2 cm same size FC. Further, radiographic results were compared by matching propensity score between two groups.There no statistically significant differences in angiographic after matching. Successful occlusion was 89% 86.8% FC...

The purpose of this study was to compare the outcomes coil embolization using a 0.009 inches primary outer diameter as finishing (FC) that 0.01 inches.From February and August 2020, 131 aneurysms performed FC with second loop 1 mm, were reviewed retrospectively, conducting propensity score matching logistic regression analysis. Angiographic results such as, occlusion grade, packing density, failure event compared between GALAXY G3™ MINI microcoil (n = 54) coils 77).There no statistically...

Objective: We conducted this study to evaluate outcome of delayed cranioplasty using frozen autologous bone flap following decompressive craniectomy in patients with traumatic brain injury. Methods: In 27 patients, 30 sites have undergone flaps the past 3 years. After craniectomy, were stored at -40°C for 316 days (mean, 55.6 days). Bone thawed room temperature before and repositioned. Serial follow-up skull x-ray and/or computed tomography was performed monitor bony resorption other...
